  • Assessment of Sedimentation Rate in Rain-Fed Irrigation Tank Systems Under
           Different Agro-Climatic Zones in Karnataka, India
    • Authors: U. Satishkumar; G. S. Dasog; P. Balakrishnan; K. Ramaswamy
      Pages: 47 - 56
      Abstract: Abstract The tank systems spread across Karnataka in southern India serve as traditional but sustainable means of water harvesting and flood control measures and a source of protective irrigation. In recent decades, these are fast losing their storage capacity due to sedimentation. To derive appropriate plans for rate of desiltation and reclamation, ruling rate of sedimentation and life expectancy of these tanks need to be estimated. The present investigation aims at predicting sedimentation rate of 254 tanks spread over different agro-climatic zones of Karnataka to assess the influence of climatic conditions along with topography and soil conditions. The modified Morgan Finney, a lumped sediment yield model, was used which agreed well with the measured sediment yield through capacity-contour and sediment concentration methods. The sediment yield (0.7–1.1 kg m−2) rate does get influenced by climate, the slope and soil characteristics together and would help in evolving desiltation plans. The life expectancy of the sample tanks varied from 2.0 to 85.1 years.

  • Response of AquaCrop Model to Different Irrigation Schedules for Irrigated
    • Authors: G. S. Pawar; M. U. Kale; J. N. Lokhande
      Pages: 73 - 81
      Abstract: Abstract Agricultural sector faces the challenge to produce more food with less water by increasing crop water productivity. As such, the question of improving the present level of crop water productivity in general and for irrigation in particular assumes a great significance in perspective water resource planning. This study was undertaken to improve water productivity, i.e., ‘more crop per drop.’ In this study response of cabbage to different irrigation schedules under mulch and non-mulch condition using calibrated AquaCrop model was evaluated. AquaCrop is a crop model that simulates yield response to water developed by FAO and is appropriate to consider effects where water is the limiting factor for crop production. AquaCrop was calibrated for cabbage (Brassica oleracea var. capitata), a leafy vegetable. Simulations were carried out for the period November 27, 2013, to February 19, 2014 with T1, T2, T3 (treatments irrigation scheduling at 50 % moisture depletion of available water capacity under black, silver, and no polyethylene mulch with drip irrigation) and T4, T5, T6 (irrigation scheduling at 100 % evapotranspiration under black, silver, and no polyethylene mulch with drip irrigation). The model provided excellent simulation of canopy and yield. The harvest index was observed as 80 % for cabbage. Formulated Schedule with S1, S2, S3, S4, and S5 (irrigation schedule at 110, 90, 80, 70, and 60 % ETc) and S6, S7, S8, S9, and S10 (mulch + Irrigation schedule at 110, 90, 80, 70 and 60 % ETc). S8 saved 25.19 % water with only 4.63 % reduction in the yield of cabbage head compared to control and resulted in water use efficiency as 6.05 kg m−3. Thus S8 is recommended to be used for cabbage production, to water productivity.

  • Validation of Seed Weight-Associated SSR Markers and Their Usefulness in
           Distinguishing Chickpea Genotypes According to Seed Size
    • Authors: Vaishali V. Borse; Pawan L. Kulwal; Laxman B. Mhase; Ashok S. Jadhav
      Abstract: Abstract Chickpea is an important cool-season grain legume. High-quality seed has the potential to attract premium prices. Hence, the breeding for desirable quality traits, including seed size and weight, is important. A set of 27 chickpea genotypes comprising 14 small and 13 large seeded, representing desi and Kabuli types, were used in the present study. A total of 43 SSR markers which were earlier reported to be associated with 100-seed weight and yield-contributing traits following QTL mapping in unrelated genetic background were used for validation purpose. Out of 43 SSR primers, 33 showed polymorphism amplifying 135 alleles. Neighbor joining-based analysis separated small- and large-seeded genotypes into two broad groups. These markers could distinguish small-seeded chickpea from that of large-seeded ones as well as desi types from that of Kabuli types, thereby validating all these QTL-linked markers in different genetic backgrounds. Fifteen of these primers also amplified 20 unique alleles in 13 chickpea genotypes and can be useful in molecular characterization and identification of specific genotype which has now become mandatory under Protection of Plant Varieties and Farmers Rights’ Act of India.

  • Electrophoretic Separation of Humic Acids Isolated from Tropical Soils
           Through Modified Denaturing Polyacrylamide Gel Electrophoresis
    • Authors: Divya Pandey; Abhijit Sarkar; S. B. Agrawal; Madhoolika Agrawal
      Abstract: Abstract Electrophoretic separation of humic acids obtained from soil was attempted through denaturing polyacrylamide gel electrophoresis (dn-PAGE) by modifying the known methods. The modifications of sample preparation and gel composition led to significant improvement in both visibility and intensity of humic acid profile. The comparative profile showed a similar nature of humic acid components in all the samples and the commercial standard. The Fourier transform infrared spectroscopy (FTIR) spectra indicated the presence of carboxyl and carbonyl functional groups and aliphatic chains in humic acid samples. The modified method facilitated better separation of humic acid. The results of the present study indicate the potential of dn-PAGE for electrophoretic separation of different components of humic acids.

  • Assessment of Water Retention Performance of Pectin-Based Nanocarriers for
           Controlled Irrigation in Agriculture
    • Authors: Raineesh Sharma; Jaya Bajpai; A. K. Bajpai; Somen Acharya; Bhuvanesh Kumar; R. K. Singh
      Abstract: Abstract This paper describes synthesis and characterization of calcium-crosslinked nanocarriers of pectin biopolymer and examines their possible applications in controlled irrigation in agriculture. Nanocarriers were characterized by Fourier transform infrared spectroscopy for structural characterization, while the size and surface morphology of the particles was studied by field emission scanning electron microscopy. The water sorption capacities of nanocarriers were investigated under the influence of various experimental factors such as varying amounts of biopolymer and crosslinker, different pH and temperatures of the swelling media. The capacity of the nanocarriers to retain imbibed water was judged by conducting their deswelling experiments. The so-prepared water-loaded nanocarriers were applied to soil, and soil pot experiments were conducted to see their water-releasing potential. Soil pot studies indicated that a judicious combination of soil with pectin-like hydrophilic polymers can be used in arid and semi-arid areas to enhance the drought tolerance of plants by providing sustained irrigation. The effect of different amounts of nanocarriers was studied to evaluate the moisture retention properties of the soil.

  • Agriculture and Poverty Responses to High Agricultural Commodity Prices
    • Authors: Saeed Solaymani
      Abstract: Abstract A rise in global agricultural commodity prices negatively affects the wellbeing of poor people, especially in developing countries and inversely for a decline in prices of these commodities. On the other hand, they may gain or lose from high or low prices especially those groups that work in production of these commodities. This study, by applying a computable general equilibrium approach, aims to investigate the impacts of high and low agricultural commodity prices on agricultural sector and poverty across nine household groups in an unemployment situation of factors of production. It is found that, as a whole, a 45% increase and decrease in agricultural commodity prices negatively influences the economic performance of Malaysia, in real terms, by 0.24 and 0.91%, respectively. While high agricultural price stimulates the investment and export of agricultural sectors and aggregate household consumption, lower agricultural commodity prices declines investment and export in these sectors and causes a decrease in aggregate household consumption. Although both high- and low-price scenarios increase the poverty level of all household groups, with greater magnitude for lower-price scenario, all rural household groups compared to urban groups experience more increase in their poverty.

  • Site-Specific Fertilizer Nitrogen Management Using Optical Sensor in
           Irrigated Wheat in the Northwestern India
    • Authors: Bijay-Singh; Varinderpal-Singh; Yadvinder-Singh; H. S. Thind; Ajay Kumar; O. P. Choudhary; R. K. Gupta; Monika Vashistha
      Abstract: Abstract An optical sensor-based fertilizer nitrogen (N) management strategy that relies on visible and near-infrared spectral response from plant canopies was evaluated for irrigated wheat in the northwestern India. GreenSeeker™ optical sensor-guided fertilizer N dose, computed from an estimate of potential yield and response index, takes into account both the temporal and field-to-field variabilities and is applied only once after measuring in-season spectral response from the crop canopy. Seven field experiments were conducted in four wheat seasons to decide whether to apply the optical sensor-guided fertilizer N dose at 2nd or 3rd irrigation stage and to work out the appropriate N management before applying it. Robust relationships between in-season sensor-based estimates of yield and actual wheat yields were observed both at 2nd (R 2 = 0.64) and 3rd (R 2 = 0.86) irrigation stages of the crop. GreenSeeker-based fertilizer N management resulted in high yield levels and high N-use efficiency. Application of 30 kg N ha−1 at planting and 45 kg N ha−1 at 1st irrigation was found to be the appropriate N management before applying the GreenSeeker-guided dose at 2nd irrigation stage. Grain yields obtained by following sensor-guided N management were at par with those observed with the blanket recommendation of 120 kg N ha−1, but with greater recovery efficiency (by 6.7–16.2%) and agronomic efficiency [by 4.7–9.4 kg grain (kg N applied)−1]. The major outcome of this study was that applying a moderate amount of fertilizer N at planting and enough fertilizer N to meet the high N demand during the period between crown root initiation stage and maximum tillering stage before applying a sensor-guided fertilizer N dose at 2nd irrigation stage results not only in high yields but also in high fertilizer N-use efficiency in irrigated wheat.

  • Genotypic Variation of Microelements Concentration in Sesame ( Sesamum
           indicum L.) Mini Core Collection
    • Authors: Sarita K. Pandey; Eshita Majumder; Tapash Dasgupta
      Abstract: Abstract Evaluation of germplasm for mineral content and selecting varieties with high quantities of essential minerals and incorporating those varieties in breeding program can assist in developing mineral-efficient crops with higher yield which can accumulate minerals from marginal soil. Sesame an oldest oilseed crop is a popular food with medicinal value although its production is often focussed in marginal and sub-marginal lands. In the present study, 60 sesame genotypes of diverse origin collected from Bangladesh, Bulgaria, India and USA were examined in the acid-digested samples by atomic absorption spectrophotometer for Fe, Zn, Cu, Mn, Cr and Co contents. All elements except Cr were found to be highly variable among genotypes. A significant discrimination showed that elements content in the sesame seeds was a seed coat coloured specific character. High-yielding developed varieties of India contain high Zn but low Fe concentration in seed. The concentration of mineral elements in black-seeded genotypes was significantly higher than those in white seeded. The indigenous collections were found to be a good reservoir of mineral elements. Correlation study among trace elements and yield attributes indicated that though Fe and Zn were not correlated significantly with yield and its components, but the two elements were interrelated. Phenotypic and genotypic coefficient of variability and heritability were high for Fe and Zn. The study suggests that observed large genetic variability for element concentrations in the genotypes provides good prospects to breed improved sesame cultivars with elevated levels of micronutrients to mitigate mineral deficiency.

  • Using Credible Soil Loss Tolerance Value for Conservation Planning and
           Managing Diverse Physiographic Regions in Rajasthan
    • Authors: R. K. Singh; J. Somasundaram; Brij Lal Lakaria; D. Mandal; B. K. Sethy; N. K. Sinha; R. Lal
      Abstract: Abstract Accelerated soil erosion degrades soil quality and undermines ecosystem functions and services. It is important to assess the severity of erosion, demarcate tolerable limits for sustainable crop production, conservation planning for soil resources, and identify the alternative land uses. Irrespective of soil type, climate and vegetation cover, the tolerable level of soil erosion in India has traditionally been taken as 11.2 Mg ha−1 year−1. However, this is an excessive rate for most agro-ecosystems and land uses; hence, this study aims to establish credible soil loss tolerance (‘T’ values) for some soils of western India on the basis of critical soil parameters (i.e., bulk density, infiltration rate, total organic carbon and soil reaction). The condition of a soil or ‘soil state’ (S) is defined through a quantitative model involving different soil functions. The ‘T’ values for some soils of western India ranged between 2.5 and 12.5 Mg ha−1 year−1 compared to default ‘T’ value of 11.2 Mg ha−1 year−1. About 50% of the land area has ‘T’ value >10 Mg ha−1 year−1, and the remaining 50% has <7.5 Mg ha−1 year−1, of which 13.02 M ha is having only ‘T’ value of 2.5 Mg ha−1 year−1. Using the revised ‘T’ values for soil mapping units will help in planning of appropriate conservation measures for effective erosion control, sustainable crop production and improved watershed management in the Rajasthan State of western India.

  • A Comprehensive Study of Variation in Selected QPM and Non-QPM Maize
           Inbred Lines
    • Authors: Ankita Sood; Kalpna Thakur; P. N. Sharma; Dorin Gupta; Avinash Singode; Maneet Rana; S. Lata
      Abstract: Abstract To enhance the nutritional value of maize (Zea mays L.), genetic characterization and conversion of common maize into crop enriched with quality protein maize may be beneficial. With the hope of producing a superior maize cultivar, the pattern of relationship among 40 maize inbred lines (QPM and non-QPM) adapted to hills was examined using molecular, biochemical and morphological characteristics. Among the non-QPM set, early maturing lines BAJIM-08-26 and KI-30 were found superior for grain yield, and among QPM set, CML189 line was found superior for high tryptophan content. Phenotypic performance-based clustering using Mahalanobis distance revealed seven clusters. Genotypes were grouped on the basis of flowering and yield traits. Two major clusters were defined, one consisting of all QPM lines and other have all non-QPM lines. This distinction is well observed in the plot generated by principal component analysis. This information may be used in selecting genetically divergent lines for ongoing breeding programs for quality enhancement. The selected QPM line(s) could be used as donor and the well-adapted agronomically superior lines as recurrent parent for conversion of non-QPM to QPM lines.

  • Quality Characterization of Brown Rice Pasta Supplemented with Vital
           Gluten and Hydrocolloides
    • Authors: Navjot Kaur; Savita Sharma; Deep Narayan Yadav; Hanuman Bobade; Baljit Singh
      Abstract: Abstract Pasta was prepared from brown rice (var. PR 118) flour incorporated with sodium alginate (0.5–2.5%), xanthan gum (0.5–2.5%), vital gluten (2–10%) and pre-gelatinized flour (10–50%) as binders. Effect of these binders on the quality characteristics of brown rice pasta was evaluated. Incorporation of xanthan gum (1.5%), vital gluten (8%), pre-gelatinized flour (40%) individually and their combination as xanthan gum (1.5%) + vital gluten (4%) + pre-gelatinized flour (20%) were found optimum to improve the cooking quality and overall acceptability of brown rice pasta. Xanthan gum (1.5%) + pre-gelatinized flour (20%) in combination can also be incorporated into brown rice in order to prepare gluten-free pasta. In addition to being a diversified convenience food, non-wheat pasta would be suitable for people suffering from wheat intolerance. Shelf life of selected pasta samples was evaluated during storage at ambient conditions for 3 months. Type of binder and storage period did not influence the cooking quality and sensory attributes of pasta significantly (p ≤ 0.05). Least significant variation was found in moisture, water activity and free fatty acid content of pasta over 3 months of storage period.

  • Weed and Nitrogen Management Effects on Weed Infestation and Crop
           Productivity of Wheat–Mungbean Sequence in Conventional and Conservation
           Tillage Practices
    • Authors: C. P. Nath; T. K. Das; K. S. Rana; R. Bhattacharyya; H. Pathak; S. Paul; M. C. Meena; S. B. Singh
      Abstract: Abstract Weeds appear as a challenge in conservation agriculture, and hence, weed management is of paramount importance. The nitrogen (N) management under changing tillage scenarios is another important dimension of research. Therefore, a field experiment was laid out in a split-plot design with six tillage, residue and N management options in main plots and four weed control practices in subplots. The results showed that the zero tillage (ZT) + residue (R) + 75% of required N + rest N based on GreenSeeker™ (GS) and sequential application of pendimethalin followed by sulphosulphuron alone and in combination resulted in significant reductions in weed dry weight and caused a considerable increase in weed control efficiency and weed control index in wheat. Their carry-over effect was also significant on the reduction in weed growth in mungbean. Residue retention in ZT gave 5.5 and 6.1% higher wheat grain yield in 2013–2014 and 2014–2015, respectively, than the residue incorporation, whereas in mungbean the increment was to the extent of 8.4 and 7.8%. Zero tilled plots recorded 25.5 and 42.8% higher water productivity (for wheat) and mungbean productivity. Highest net energy returns were observed in ZT + R + 75N + GS in wheat in both the years. The treatment ZT + R + 75N + GS also fetched higher gross and net returns in wheat and mungbean. In all cases, herbicides with sequential application proved better than one-time ready-mix application.

  • Long-term Effects of Feeding a Novel Phytoadditive on Nutrient
           Utilization, Growth Performance, Metabolic Profile and Antioxidant Status
           of Goats
    • Authors: Santosh L. Ingale; Ashok K. Pattanaik; Shalini Baliyan; Sarita Kankoriya; Narayan Dutta; Kusumakar Sharma
      Abstract: Abstract The present study was undertaken to ascertain the health-promoting effects of a phytoadditive (PA) having confirmed in vitro antimethanogenic potential. The PA was prepared by mixing fixed proportions of Withania somnifera, Boerhavia diffusa and Holarrhena antidysenterica. Eighteen Jamunapari kids of three months of age were used in a 180-day study. The kids were divided into three equal groups and supplemented with the PA at 0 (PA-0), 1.5 (PA-1.5) and 2.5 (PA-2.5) percent of expected mean daily feed (DM) intake. A metabolism trial conducted following 180-days of feeding trial indicated no variations (P > 0.05) in intake and digestibility of organic nutrients. The plane of nutrition and nitrogen retention was also similar (P > 0.05) across the treatments. Blood collected at 30-days intervals was assessed for erythrocytic antioxidants and metabolic indices. The PA improved (P < 0.05) the erythrocytic lipid peroxidation, and activities of superoxide dismutase, catalase and glutathione peroxidase. The serum levels of glucose, urea, total protein, globulin and alanine aminotransferase remained similar (P > 0.05) among the groups, whereas serum levels of albumin were improved (P < 0.05) in the PA-supplemented groups with a reverse trend (P < 0.05) for total cholesterol. The serum aspartate aminotransferase activity was reduced (P < 0.05) in both the PA-groups. The dietary treatments imparted no difference (P > 0.05) on the average daily gain (g) which was 35 ± 4.0, 31 ± 3.4 and 34 ± 4.0 for the PA-0, PA-1.5 and PA-2.5 groups, respectively. The feed conversion ratio was also comparable across the dietary groups. Overall, it is concluded that while the dietary supplementation of the PA had no influence on the nutrient metabolism or growth, it did stimulate the antioxidant status of growing kids and thus possess potential to be of practical value in stressful management situations.

  • Potentials of Bamboo-Based Agroforestry for Sustainable Development in
           Sub-Saharan Africa: A Review
    • Authors: Samuel T. Partey; Daniel A. Sarfo; Oliver Frith; Michael Kwaku; Naresh V. Thevathasan
      Abstract: Abstract There is widespread assertion among scientists, government and development experts that bamboo agroforestry could contribute to sustainable rural development in Sub-Saharan Africa (SSA). However, there are limited available data to verify the suitability of the system in the region. In addition, the current state of knowledge and adoption of agroforestry in SSA offers very little guidance as to which type of agroforestry systems bamboo could be integrated. Here, we reviewed the potential socioeconomic and environmental benefits of bamboo agroforestry and accentuate implications on sustainable rural development in SSA. In addition, we analysed potential research areas that could be intensified, so that future developments and scaling-up of bamboo agroforestry can be rooted in robust scientific findings rather than the intuitions of governments and development actors.

  • A Farmer-Led Approach to Achieving a Malnutrition-Free India
    • Authors: Nitya Rao; M. S. Swaminathan
      Abstract: Abstract Overcoming the widespread malnutrition prevailing in the country has become a priority task. Based on the experience of the green revolution, it is clear that a farmer-led approach is essential for achieving the goal of freedom from malnutrition. Also there is need for concurrent action in the following five areas—overcoming undernutrition, protein hunger as well as hidden hunger caused by micronutrient malnutrition, attention to clean drinking water and sanitation, and finally ensuring safe handling of food at the post-harvest level to avoid mycotoxins. If we are to achieve our goal of ending malnutrition in the country, it is essential that agriculture, nutrition and health are attended to in an interactive way.

  • Edaphic Stresses and Agricultural Sustainability: An Indian Perspective
    • Authors: P. S. Minhas; G. P. Obi Reddy
      Abstract: Abstract Increase in agricultural productivity in India is likely to come primarily from sustained intensification, but the increases in the recent past have been accompanied by severe degradation of agroecosystems and the resultant edaphic constraints. The emerging nutrient deficiencies with mining (8–10 million tonnes of NPK annually) along with acidity (pH < 5.5 in 17.93 M ha), salinity (6.73 M ha) and soil contaminants are the most common chemical stresses. Among the physical stresses, severe soil erosivity (water 82.47 M ha and wind 12.40 M ha), shallow soils (26.4 M ha), soil hardening (21.4 M ha) and low water holding capacity (13.75 M ha) threaten the soil productivity. The soils are inherently low in low organic carbon, and climate change is further impacting the farming systems. Conservative estimates show that about two-third losses in agricultural production are caused by these edaphic factors. Therefore, to alleviate the adverse effects of multiple edaphic factors, a holistic approach to build up systems perspectives is urgently required. The new tools emerging especially in the areas of conservation agriculture, precision irrigation technologies, biotechnology and omic sciences etc., are opening up new opportunities for tackling these stresses.

  • Estimating Water Balance of Small Reservoirs in Arid Regions: A Case Study
           from Kachchh, India
    • Authors: Deepesh Machiwal; Devi Dayal; Sanjay Kumar
      Abstract: Abstract Quantification of hydrological processes is necessary for management of small reservoirs especially in arid regions characterized by hot climate, scanty rainfall magnitudes and large rainfall variability. This study focuses on estimating inflow and outflow components of a small reservoir situated in arid Kachchh region of Gujarat, India, by developing a water balance model. Daily reservoir water levels were monitored for years 2012 and 2013. All water balance components, i.e. rainwater directly falling into reservoir, surface runoff, irrigation extractions, and evaporation and percolation, were either measured or estimated. Results indicated that rainfall has a fair control on amount of harvested runoff water. In year 2012, meagre rainfall (79 mm) could store 925 m3 of water with 66 cm depth. In contrast, reservoir water levels were at 2.85 m depth in year 2013 with full capacity of 24,879 m3 when rainfall totalled to 291 mm. The mean percolation rate (0.14 cm h−1), determined from 24-h long-term infiltration tests, revealed that full storage will get depleted within 85 days. A major portion (51%) of storage was lost through evaporation and percolation, and only 21% stored water could be utilized for supplemental irrigation. This finding suggested that suitable measures need to be adopted to check evaporation and seepage losses from the reservoirs in arid regions for improved agricultural productivity. Moreover, results of this study may be useful for water resources managers and decision-makers to develop appropriate operational strategies for the reservoirs in the study area as well as in other arid regions of the world.

  • Crack Formation in a Swell–Shrink Soil Under Various Managements
    • Authors: D. K. Painuli; M. Mohanty; Nishant K. Sinha; A. K. Misra
      Abstract: Abstract Swell–shrink soils generate wide and deep cracks, generally considered undesirable for crop husbandry. However, there is a lack of information about the management options available to reduce formation of wide and deep cracks in such soil. Therefore, the present study was conducted on an Entic Chromusterts. The results revealed that width (mm) and depth (mm) were 7 and 23, respectively, for initial soil wetness by weight 43% compared to their negligible values for initial wetness 14%, at bulk density 1.15 g cm−3, and these two parameters were 7 and 27 mm, respectively, compared to 6 and 19 mm at bulk density 1.02 g cm−3. Thus excessive wetness and higher compaction generated wide and deep cracks and should be avoided. Incorporation @10 t ha−1 of organic matter and gypsum in the soil reduced width and depth of the cracks and may be practiced; temperature beyond 35 °C generated narrow and shallow cracks. These management options should, however, be adapted for field application as per local needs and available resources.

  • Influence of Chromium Contamination on Carbon Mineralization and Enzymatic
           Activities in Vertisol
    • Abstract: Abstract Chromium (Cr) contamination may affect different biochemical process in the soil. In a laboratory experiment, graded doses of hexavalent chromium were applied to a clay loam soil to investigate the impact on carbon (C) mineralization rate and the enzymatic activities at various time intervals. The maximum reduction in C mineralization was noticed at 100 mg/kg Cr at 45 days after incubation. Initially, the C mineralization rate was high but decreased at faster rate with lapse of time. It was observed that increasing the Cr concentration from 0 to 100 mg/kg resulted in reduction in dehydrogenase, alkaline phosphatase and fluorescein diacetate activities to the extent of 70, 63 and 41%, respectively. Among the enzymes, dehydrogenase activity was more sensitive to Cr toxicity. In conclusion, Cr toxicity negatively affected the microbial mediated C mineralization and enzymatic activities, which may adversely affect nutrient transformation in the soil and deterioration of soil health.

  • Path Loss Estimation for Wireless Underground Sensor Network in
           Agricultural Application
    • Authors: Xiaoqing Yu; Wenting Han; Zenglin Zhang
      Abstract: Abstract Path loss models are used to estimate the path loss between transmitter and receiver in applications that involve transmission of electromagnetic waves. This paper describes the wireless underground sensor networks, which communicates within the soil and is different from the terrestrial wireless sensor network. An integrated study of electromagnetic waves propagation for a wireless underground sensor network is described in this paper. Here, path loss model and signal strength are presented, because of electromagnetic waves attenuation in the soil medium. Tests were conducted at various soil volumetric water contents and node deployment depths using three different frequencies, when soil consists of 0% sands, 35% silt and 15% clay. The results showed that radio signal path loss was minimum when frequency and moisture content are low. The experimental results revealed that a 20% increase in the soil moisture content increased the path loss by more than 30%.
