  • Visual Tracking using Invariant Feature Descriptor

    • Abstract: The process of identifying the state of an object in a video sequence is referred as visual tracking. It is mainly achieved by using the appearance information from a reference image to recognize the similar characteristics from the other images. Since a digital image is built-up with rows and columns of pixels that are represented with finite set of digital values, the appearance information is measured with a mathematical formulation that is known as image intensity. The problem of distinguishing the intensity of the object of interest from the other objects and the surrounding background is always the main challenge in visual tracking. In this study, a novel invariant feature descriptor model is introduced to address the aforesaid problem. The proposed framework is inspired by the theoretical model of local features that has been widely-used for image recognition. From the large number of diversified scenarios in the surveillance applications, the performance of the proposed model is demonstrated with the benchmarked dataset of single-target tracking. The experiment results shown the advantage of our proposed model for tracking non-rigid object in the changing background as compared to other state-of-the-art visual trackers. In addition, the important aspects of the proposed model are analyzed and highlighted as well in the experimental discussions. 
  • The Analysis of High Dimensional Contingency Table with Interactions

    • Abstract: This paper is focused on the analysis of categorical data in a 2 × c × K contingency table. The theoretical frame work of a 2 × c design is extended to 2 × c × K with provision for testing interactions among subsets of either lower or upper columns of the designated table. The developed chi square tests for the total interactions as well as for the partitions are shown to be significant and the degrees of freedom additive. 
  • Towards a Higher Learning Motivation among Malaysian Undergraduate
           Students - A Case Study of Motivation Change in Malaysian Undergraduate
           Students after the Global Study Program (GSP) in Japan

    • Abstract: This research paper outlines the Malaysian and Japanese undergraduate students' learning motivation, before and after joining a Global Study Program (GSP) held in Chiba University, Japan from 14 March-28 March 2016. A total of 15 Malaysian undergraduate students from Multimedia University, consisting of 2nd year to 4th year students, joined the GSP together with 15 Japanese 1st year to 4th year undergraduate students from Chiba University. The study focused on examining students' learning motivation in three experiment phases. The 1st phase of experiment consisted of conducting surveys on all students before the commencement of GSP. The 2nd phase of experiment consisted of daily observational measurements toward students' motivation and performance. Lastly, the 3rd phase of experiment consisted of conducting the same surveys again on all students after the GSP. Note that the survey consisted of 29 questions covering value components, expectancy components, affective components and self-perceived learning components. The results of this study indicated that the learning motivation of Malaysian and Japanese undergraduate students had significantly improved after joining the GSP course. 
  • Application of Morphological Component Analysis to Optical Image Fusion

    • Abstract: The image fusion technique is widely used in remote sensing. Its purpose is to provide comprehensive information without arte facts by combining the partial information from different source images. In this study, we propose a new model of images fusion with very high spatial resolution. We use the separation capacities of the Morphological Component Analysis (MCA) to extract the smooth and texture components of our images. These morphological components are then fused separately using the decomposition in the Laplacian pyramids for the smooth part and bivariate Hahn polynomials for texture part. Finally the image fusion is obtained through linear combination of merged smooth and texture components. The experiments carried out on IKONOS, LANDSAT and Quick Bird remote sensing images show the good performances of our method which has been compared to conventional methods. The performances obtained in our experiments are characterized by a small global metric such as ERGAS equals to 3.88 for IKONOS image and 3.65 for QuickBird image compared to 8.70 for IKONOS image and 6.97 for QuickBird for conventional HIS algorithms. We also have a mean loss of 15% for spectral information com pare to those of the conventional methods which revolve around 25%. The degradation of spatial information in order of 17% in contrast to conventional HIS algorithms which oscillate around 21%.

  • High Gain Multiband Stacked DRA for WiMax and WLAN Applications

    • Abstract: Dielectric resonator antennas find widespread applications in high speed wireless systems because of low loss, compact size and light weight. In this study, performance of a multiband Dielectric Resonator Antenna (DRA) with higher gain and improved radiation efficiency for 3.8 GHz band Wi-Max, fixed point satellite links and 4.8GHz band 5G services and 5GHz wireless networks is presented. The proposed design consists of stacked rectangular dielectric resonator fed by a microstrip line placed above grounded Arlon substrate. Simulation results of the proposed DRA shows dualband operation from 3.65 to 4.45GHz and 4.7 to 5.6GHz with impedance bandwidth of 20.25 and 17.47% respectively. The gain and directivity of the DRA is 8.22 and 8.17dB respectively
  • Characterization of Activated Carbon from Eggshell Membranes Prepared
           Using Sodium Acetate and Zinc Metal Activation

    • Abstract: The eggshell membranes of ducks and hens were carbonized or activated with 4 wt% sodium acetate or zinc at 400-600°C. The carbonized or activated products were characterized by SEM-EDS, TEM, FTIR and XRD. It was found that the suitable activation temperature for eggshell membranes is 500°C with 30.03-35.26% yield. The activation performance of CH3COONa for eggshell membrane activated carbon production was higher than that of Zn metal. The CO3-2, Ca-O, C=C, Na-O and C-O functional groups have been formed on the surface of eggshell membrane activated carbon materials during both CH3COONa and Zn activation. Furthermore, CaO, MgO, Na2O and ZnO have also accumulated on eggshell membrane activated carbon materials with high content and regular dispersion. It was shown that the particles on the duck eggshell membrane activated carbon formed with Zn had weaker attachment on the surface than for duck eggshell membrane activated carbon formed with CH3COONa at same temperature. The XRD and TEM results revealed that the eggshell membrane activated carbons consist of an amorphous carbon matrix with some disordered graphite carbon matrix, spherical particles and nanofiber.
  • Improving Routing Discovery Based Velocity-Aware Probabilistic Using AODV
           with Link Prediction in Mobile Ad-hoc Networks

    • Abstract: The current process associated with enhancing the QoS in routing for MANETs has reserved a high importance due to the limitation of available route discovery in dynamic topology. The conventional methods of route discovery schemes in MANETs are commonly designed in order to estimate the number of nodes in routes using the standard probabilistic models. Such models are utilized by estimating the flood in a network using the RREQ packets. However, the current development in mobility, frequent breakages become more common which as a result lead to relocate the properties of same routes. As such, the network may experience additional demands for channel contention and high packets collision rate. For this, we proposed a new scheme for enhancing the routing discovery based velocity-aware probabilistic using AODV properties with link prediction in MANETs. The result of the new scheme was found to outperform the old one in which it offers better ROH, throughput and delay time. This study provides an important insight for predicting the routing failure in a network when using the velocity-aware probabilistic scheme alone.
  • Research of Effect of Peculiarities of Creasing a Polymer Sheet Material
           on a Rigid Base on Parameters of a Folding Operation

    • Abstract: Folded elements are widespread in design of various products. They are made of sheet metal, cardboard, plastics or other materials. For example, heat exchangers, printed products, cardboard or plastic folders, folded fillers for three- or multilayered panels, which are made of paper, cardboard or plastics material can be mentioned. Although folded fillers are significantly advanced in terms of structural or operational performance, their wide application is hindered by poor mastering of the mass production technology. At present, the process of shaping folded fillers using a creasing operation on a rigid base is the most prospective. However, the creasing operations on polymer materials while manufacturing folded fillers are performed with deformations significantly exceeding a uniform strain limit. There are no research works on the subject in the known technical literature. Therefore, the work intended to resolve the matters filling the gap is relevant. The purpose of the research is to obtain results enabling to develop optimal processes for shaping folded fillers of polymer materials taking into account considerations on the creasing on a rigid base. Based on the analysis of the initial and the final condition of the material at the creasing area, a mechanism of strain has been developed, objectives of determinations of the final shape in the creasing area have been solved analytically using an equilibrium equation adopted for the objectives in question; conditions for incompressibility, true (logarithmic) strain values, flat cross-section hypothesis have also been determined. As a result of the research, analytic dependences have been obtained for determinations of the residual thickness, curvature of the material at the creasing area, residual interfacial angle after release of the load. Experimental studies of the above parameters were carried out and comparisons with calculated values are shown.
  • Fabrication and Mechanical Properties of Glass Fiber/Talc/CaCO3 Filled
           Recycled PP Composites

    • Abstract: Until now, recycling studies brought to the agenda after the rapid increasing of plastic materials in every area and causing those plastics to environmental pollution after discarding them following the utilization. The purpose of recycling plastic waste is to minimize environmental pollution and to create of new resources. To perform the present study, Recycled Polypropylene Granules (RPP) belonging to Polypropylene (PP) will be used in most particularly in the automotive and in the packaging industry finding application area behind the Low Density Polyethylene (LDPE). To develop the several properties (physical and thermal) of RPP polymer and to get close to or greater value to the original PP features, different rates of micron-sized glass fibers, talc and CaCO3 are added into the polymer. By recycling waste, demand for natural resources (such as oil, which is plastic’s raw materials) will decrease and rapid consumption of energy sources will be prevented while providing the protection of natural resources. Raw materials imports would be reduced due to the usage of recycled products. In this study, Recycled Polypropylene Granules (RPP) were obtained from companies and glass fiber/talc/CaCO3 additive RPP granules in different ratios were produced with compounding extrusion process. These produced new composite pellets were produced in injection molding machine by means of designed mold to perform tensile and impact tests. In the thermal analysis, the melting temperature and crystallization rate were determined by DSC analysis; the thermal decomposition temperature was determined by TGA analysis. Micro structural examination was done using a Scanning Electron Microscope (SEM). 
  • Simple Fabrication and Characterization of Piezoelectric Nanogenerators
           from Cobalt-Doped Zinc Oxide Nanofibers

    • Abstract: The ferromagnetic cobalt doped into Zinc Oxide (ZnO) crystals is a promising method for enhancing the performance of Piezoelectric-Based Nano Generators (PENGs). The study reports the characterization and testing PENGs which simply fabricated from cobalt-doped ZnO nanofibers (NFs) synthesized by electro spinning machine. The electro spinning processes were conducted at a flow rate of 4 μL/min and at various cobalt concentrations followed by sintering at a temperature of 500°C. The X-Ray Diffraction (XRD) spectra demonstrate that the crystalline diameter of Co-doped ZnO NFs increased as the content of cobalt increased, up to a concentration of 9%. Meanwhile, the maximum output voltage and power density of PENGs with Co-doped ZnO NFs were 221.6 mV and 148.8 nW/cm2, respectively when the PENGs were subjected to a cyclic mechanical load of 0.5 kg. Therefore, PENGs fabricated from Co-doped ZnO NFs are challenging for the next generation of self-powered devices.
  • Identification of Characteristics of Land Cover in Mangkauk Catchment Area
           Using Support Vector Machine (SVM) And Artificial Neural Network (ANN)

    • Abstract: Land cover is anything that includes any types of appearance on the surface of the earth on a particular land. Information related to land cover can be used as at the parameter to determine the amount of runoff in a catchment area. This study was conducted in the Catchment Area (CA) of Mangkauk using Landsat 8 OLI/TIRS 2014 scene path/row 117/62 with the methods of Support Vector Machine (SVM) and Artificial Neural Network (ANN). The classification of land cover in Mangkauk catchment area included forests, plantations, shrubs, reeds/grasses, rice fields, open lands, settlements and water body. Based on the accuracy test of land cover classification using SVM, the value of the overall accuracy was 97.22% with Kappa Coefficient 0.96, while using ANN 86.33% with Kappa Coefficient 0.79.
  • Formal Credit and its Impact on Income - Evidence from the Poor Households
           in Vietnam

    • Abstract: The poor households are normally financial constrained, which inhibits them from income-generating activities. Formal credit market in Vietnam has been more and more improved and thus the poor households can be more accessible to formal sources. Thenceforth, they can relax their financial constraint and then invest in on-farm or off-farm activities to generate income and escape poverty in longer run. This research is aimed at examining the impact of formal credit on income of the poor households in rural Tra Vinh, one of the poorest provinces in Vietnam. The research applies the data from a survey of 381 rural poor and Propensity Score Matching (PSM) method for quantitative analysis. The estimated results find that formal credit borrowers benefit from self-employment activity rather than other income-generating activities. In particular, borrowers from formal sources have significantly higher self-employment income than non-borrowers, but there is no significantly different among them in terms of income from agriculture and wage sources.
  • Manufacturing Strategy and Competitive Advantage: A Mediating role of
           Organizational Culture (A Case Study of Small Industry Batik Trusmi

    • Abstract: The effect of manufacturing strategy and competitive advantage has empirically resulted varied studies with regards to industry or service sectors as object of the study. Manufacturing strategy on one side directly affects competitive advantage in addition to giving an effect to competitive advantage mediated by organizational culture variable on the other side. Regarding this condition, this study aims to investigate the effect of organizational culture mediation toward the correlation between manufacturing strategy and competitive advantage in small industry batik Trusmi. 200 batik makers located in Trusmi, Cirebon, Indonesia were selected as respondents of the study. They consisted of 131 males and 69 females dominantly age 41 to 60. Correlation and regression analysis were employed as methods of the study. It can be concluded based on the regression test on manufacturing strategy and competitive advantage variables and on the presence of organizational culture as mediator variable that there is a significant correlation between manufacturing strategy and mediator variables (organizational culture) and competitive advantage variable altogether. It shows that there is no a direct effect of manufacturing strategy variable toward competitive advantage variable.
  • Experimental Investigation of Thermo-Physical Properties of Soil Using
           Solarisation Technology

    • Abstract: Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases of fertilizers (chemical fertilizer, organic fertilizer and without fertilizer). The parameters explored in this study include soil bulk density (Mg/cm3), soil porosity (%), soil volumetric moisture content (cm3/cm3) and soil thermal diffusivity (m2/sec). Data management and analysis were performed using SAS 9.1 statistical software and the spilt-plot under Randomized Complete Block Design (RCBD). The results show that soil Tillage Depth (TD) strongly influences TPP, as well as a significant effect on soil bulk density (ρb), porosity (Φ), volumetric moisture content (θ) and thermal diffusivity (D). The results also reveal that a tillage depth of 15 cm produces lower values of ρb, θ and D (1.25 Mg/cm3, 0.131 cm3/cm3 and 1.24×10-6 m2/sec, respectively) and a higher value of Φ (52.78%). In addition, the finding indicates that ρb is increased by increasing TD. There was a significant positive correlation between the number of plastic film and parameters studied. The soil double plastic film produced lower values of ρb and D for soil (1.253 Mg/cm3, 7.76×10-7m2/sec). However, it recorded higher values for Φ and θ for soil (52.70% and 0.231 cm3/cm3, respectively). Furthermore, the current study shows significant differences between the types of fertilizers on ρb. Organic Fertilizer (OF) obtained a lower value of ρb (1.2 Mg/m3), compared with chemical fertilizer and without fertilizer (1.28 and 1.31 Mg/m3, respectively). In contrast, contrary to expectations, this study did not find significant differences between the types of fertilizer on D and θ for soil. A positive correlation was found in the interaction between the studied factors in the parameters. Furthermore, D increased with increasing soil bulk density (pb) and tillage depth.
  • Extracting Unique Personal Identification Number from Iris

    • Abstract: The aim of this research is to propose an enhanced model that significantly reduces the noise in the iris templates and thus present an efficient and reliable iris recognition system. Accuracy of Iris recognition system significantly depends on reducing noise at every stage of recognition process especially at eye image acquisition and iris segmentation stages. The proposed Iris recognition model combines Canny edge detector and circular Hough transform which yields more rapid and accurate localization of Iris inner and outer boundaries. The eyelid and eyelashes occlusion is also dealt with by applying non maxima radial suppression technique. The segmented Iris area is then normalized and converted from annular shape to fixed-sized rectangular block. In this stage all iris templates converted from circular to rectangular shape will have standard dimensions thus enabling Iris recognition system to perform comparison between them. Fast Fourier Transform function is then applied to normalized Iris image. Input image is viewed as a signal that is converted from time to frequency domain in which the number of frequencies is equal to number of image pixels. The resulting matrix is consisted of real and imaginary part represented by complex numbers. The matrix is encoded according to the pre established encoding pattern that assigns certain sequence of binary numbers to each possible combination of complex numbers thus producing Iris code. In the matching phase the iris codes are compared and if the determined degree of dissimilarity between the two is below the pre-established threshold value than the codes belong to the same user. The proposed Iris recognition method, therefore, successfully treats eyelids and eyelashes noise issues and present the efficient set of algorithms whose performance is superior compared to other existing methods.
  • Can Emotional Stability Buffer the Effect of Job Stress on Deviant

    • Abstract: The interrelationships between job stress, WDB and emotional stability have not been studied in a model to comprehend whether emotional stability could weaken the impact of job stress on employee deviant behavior. We tested a model on the moderating role of emotional stability, a personality factor, in the relationship between job stress and workplace deviant behavior. The model was developed based on the general strain theory and the integrated general model of workplace deviant behavior. Structural equation modeling analysis was conducted on survey data from 261 employees from six Malaysian public service agencies. Our results supported the proposed model. The stress-deviance relationship is significant. The stress-deviance linkage is stronger among employees who are less emotionally stable than those who are more emotionally stable. The results suggest that emotional stability as a personality factor plays a vital role in further understanding the impact of job stress on employee deviant behavior. Based on the results, the general strain theory and the integrated general model of workplace deviant behavior could serve as the bases for explaining the stress-deviance relationship and the moderating role of emotional stability.
  • A Conceptual Model for Risk Allocation in the Construction Industry

    • Abstract: Appropriate risk allocation influences positive project delivery on construction projects while inappropriate allocation results in disputes, quality shortfalls, time and cost overruns. The existing body of knowledge provides guides on how risks should be allocated between the contracting parties. Nevertheless, the full appreciation of risks allocation is rarely given as risk allocation is more than just which party should bear a risk. This study provides a conceptual model of the various ways risks could be allocated. Furthermore, the FIDIC-Redbook (1999), NEC3 2005/2006 and JCT Major building contract 2005, JBCC (2014), JLC (1972) and open national bidding contract (2013) are used to demonstrate the practicality of the conceptual model. An understanding of risk allocation prerequisites might help to mitigate risks that influence project performance negatively. The use of this conceptualization may help to assign a risk with more than one treatment option to maximize a positive outcome of a negative risk factor.
  • Stationarity and Cointegration between Health Care Expenditure and GDP for

    • Abstract: This paper explores the Granger-causality relationship between real GDP per capita and real health care expenditure per capita for Jordan during 1995 through 2013. The findings point out that the dominant type of Granger-causality is unidirectional. Furthermore, income elasticity of health expenditure is less than 1, which means that health care is a necessary good in Jordan. To this end, policies must be aimed at raising national income to improve eventually the well-being of the population.

  • Comparison of Microbial and Heavy Metal Contents in Soils and Roots under
           Mangrove Forest Stands with Different Levels of Pollution in the Niger
           River Delta, Nigeria

    • Abstract: Oil and gas exploration in the Niger Delta, has resulted to increased heavy metal contamination. It is thus postulated that increased heavy metal will lead to decreased microbial content in soil and root. To test this hypothesis ten replicates each of soil and root samples were collected from already established sites. Samples were sent to the laboratory for analyses of heavy metals (spectrophotometric method), total hydrocarbon (colorimetric method) and microbial (Sabouraud Destrose Agar) contents. The result indicates that bacterial population outnumbered fungal population in soils and roots. Similarly, there were significant differences in both microbial and heavy metal contents between highly and lowly polluted plots (p = 0.0001) and between polluted and non-polluted locations (p = 0.0001). Heavy metal has negative linear relationship with microbial content. As heavy metal increases the microbial activities reduces with implication on litter decomposition and nutrient cycling, which may eventually affect mangrove growth and development.
  • Water Filter Fabrication from a Mixture of KMnO4 Modified Kapok Carbon
           Fiber, Zeolite, Bentonite and Clay for Fe3+Removal and Water Hardness

    • Abstract: A water filter was fabricated from a mixture of KMnO4 modified kapok carbon fiber, zeolite, bentonite and kaolinite clay for Fe3+ removal and water hardness treatment. The effects of amount of KMnO4 modified kapok carbon fiber (30-60 wt%), zeolite (20-40 wt%) and sintering temperature (500-700°C) on the properties of sintered products were evaluated. The best of sintered products were tested for treatment of solutions with 5 mg L-1 Fe3+ and 40-200 mg L-1 total water hardness. The results show that the physical properties of the sintered products were affected by the contents of KMnO4 modified kapok carbon fiber and sintering temperature. The linear drying shrinkages of the mixture of raw materials increase with increasing content of modified kapok carbon fiber amounts due to the effect of water amount used for mixing process. Furthermore, firing shrinkages of sintered products increased with increasing sintering temperature for the same ratio of raw materials. Finally, the firing shrinkages and density of sintered products decrease with increasing content of the modified kapok carbon fiber at constant sintering temperature. It was shown that the sintered product made with 40 wt% of KMnO4 modified kapok carbon fiber and sintered at 600°C is suitable for filter fabrication. The KMnO4 modified kapok carbon fiber filter could adsorb 5-6% more Fe3+ at equilibrium than filter made with kapok carbon fiber. The Fe3+ was removed by adsorption and precipitation processes. The Fe3+ adsorption process of modified kapok carbon fiber filter was fitted to the Langmuir model with maximum adsorption capacity of 53.76 mg g-1. For hardness removal, the Ca2+, Mg2+ and HCO3' ions removal capacities from solutions of total hardness in the range 40-200 mg L-1 by modified kapok carbon fiber filter are 4.49-19.21 mg g-1 for Ca2+, 1.55- 5.31 mg g-1 for Mg2+ and 28.1-123.5 mg g-1 for HCO3', respectively. 
  • Least Absolute Deviation Regression and Least Squares for Modeling

    • Abstract: Considering the importance of the statistical analysis of regression in modeling based separately on study for Quantitative structure retention indices on Carbowax 20 M (ICw20M) and OV-101 columns (IOV-101) relationships (QSRR) are determined for 114 pyrazines.

  • Rutting and Fatigue Cracking Susceptibility of Polystyrene Modified

    • Abstract: The absence of studies investigating the influence of waste Polystyrene (PS) on the performance characteristics of rutting resistance and fatigue cracking resistance of the indigenous asphaltic materials Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB), has hindered the possible use of PS as a performance enhancer as observed with other asphalts from different sources thus also developing a sustainable approach for the disposal of PS. The influence of PS on TLA and TPB was investigated by measuring the rheological properties of complex modulus (G*) and phase angle (δ) of prepared blends and calculating the fatigue cracking resistance and rutting resistance parameters (G*sin δ and G*/sin δ respectively). The addition of PS to TLA resulted in an increase in the fatigue cracking resistance as well as the rutting resistance compared to the pure TPB binder. Despite having improvements in rutting resistance due to PS addition, the fatigue cracking resistance of the TPB parent binders were superior compared with the PS modified TPB blends. The incremental increase in temperatures for TPB and TLA based blends resulted in gradual improvements in their fatigue cracking resistances but gradual deterioration in the rutting resistance of the modified blends. The conclusions were identical for both the Research Program Super pave specification and the Strategic Highway Research Program specifications. There is strong rheological evidence of the possibility to utilize waste PS as an asphalt performance enhancer for both TLA and TPB thus creating a sustainable strategy for the reuse of waste PS.
  • Impact of Microfinance on the Efficiency of Maize Producers in Nigeria

    • Abstract: The study applies descriptive analysis, Slacks-Based Measure (SBM) of efficiency model and fractional regression model to data collected in 2016 using cross-sectional survey of maize producers in Nigeria. The purpose was to determine the impact of microfinance on the technical efficiency of maize producers and evaluates factors that influence inefficiency among credit beneficiaries and non-credit beneficiaries. Results show that the respective mean technical efficiency of credit beneficiaries and non-credit beneficiaries were 79 and 69%, which is far from the frontier technology. This means that technical efficiency can be improve by 21 and 31% respectively, with the same set of inputs. Slacks analysis shows that in order to attain optimum efficiency, credit beneficiaries should reduce fertilizer usage by 32.34%, seeds by 6.03%, labour by 7.79% and agrochemicals by 2.44% per hectare. Similarly, non-credit beneficiaries should reduce the usage of fertilizer slacks by about 19.48%, seeds by 2.73%, labour by 2.54% and agrochemicals slacks by 1.76% per hectare. Microfinance credit, household size, years of farming experience and education increases efficiency, while drought and age declines efficiency. Findings are useful to the farmers as appropriate input reduction for inefficient farms can be set to enable them attain optimum efficiency level. Maize producers should be encouraged to collect microfinance loan in order to increase their scale of operations and government in collaboration with research institutes should educate farmers on the actual input quantities to apply. This could help to reduce production costs, increase the farmers’ efficiency and provide maize to consumers at an affordable rate.
