  • Effect of Marination Method, Holding Temperature and Time on
           Physicochemical Parameters, Sensory Attributes and Microbial Quality of
           Broiler Chicken Breast Meat

    • Abstract: We assessed the effect of holding temperature and time on physicochemical parameters, sensory attributes, and microbial quality of unmarinated and marinated broiler chicken breast meat. A factorial arrangement of treatments (4 x 2 x 2) was used in assessing four methods (unmarinated control, immersion, injection, and tumbling), two holding temperatures (4 °C and 8 °C), and two holding times (4 and 8 h). The Pectoralis major breast meat samples were marinated and randomly allocated into treatment combinations. The highest marinade uptake was reported from the injection method (P<0.05). Injection (4 °C - 4 h; 4 °C - 8 h, 8 °C - 4 h and 8 °C – 8 h), immersion (4 °C - 4h and 8°C - 8 h) and tumbling marination (4 °C - 4 h; 4 °C - 8 h and 8 °C – 4 h) resulted the highest cooking yield (P < 0.05). Injection and tumbling resulted from the minimum cooking loss. Marination improved the external surface b* value and reduced the internal surface L* value compared to the control (P<0.05). Holding meat at 8 °C for 8h after tumbling marination reported the highest (P<0.05) score for aroma, surface color, marinade penetration, color penetration, and overall acceptability. The total microbial counts of all the treatments ranged between 3.30 and 4.45 log CFU/g. The present study concluded that holding meat at 4 °C for 8 h following injection marination was the best for the development of meat quality. The overall acceptability was highest when meat was held at 8 °C for 8 h after tumbling marination. All products tested were safe for human consumption within 42 days when stored at -18 °C.

  • Time Series Analysis of Rainfall Using Seasonal ARIMA (SARIMA) and Sama
           Circular Model (SCM): Study from Vadamaradchi, Jaffna, Sri Lanka

    • Abstract: The time series analysis was performed with Seasonal Autoregressive Integrated Moving Average (SARIMA) and Sama circular model (SCM) for the rainfall of Ampan, Karaveddi, and Puloly regions of Jaffna to understand the behaviour of rainfall and forecast it with a suitable model. Minitab 17 software was used to run the model with the available monthly data from 2013 to 2019. Time series plots were used for pattern recognition, the independence of the residuals was checked using autocorrelation function (ACF), and Lijung-Box Q statistics (LBQ). The normality of residuals was checked using probability plot. The model with the lowest predicting errors was selected to forecast the future values. The monthly rainfall fluctuates around the mean of 41.6, 71.9, and 35.3 mm for Ampan, Karaveddi, and Puloly respectively. The models SARIMA (0,0,0) (0,1,1)6, SARIMA (1,2,1) (0,1,1)6, and SARIMA (1,1,0) (0,1,1)6 were found as most appropriate for Ampan, Karaveddi, and Puloly respectively and Published on 2022-03-30 00:00:00
  • Wild Rice Species in Sri Lanka as Genetic Resources for Breeding for Brown
           Plant Hopper (Nilaparvata lugens (Stål)) Resistance in Rice

    • Abstract: Brown pl anthopper (BPH) Nilaparvata lugens (Stål.) is considered the most destructive rice pest in rice-growing countries  including Sri Lanka. Resistance breeding considered the most e conomical management strategy, starts by identifying new genetic resources for BPH resistance and comparative analysis wi th existing donors. So far, scientists have identified 38 genes/QTLs responsible for BPH resistance. This study explored the BPH resistance in five wild rice species in Sri Lanka, inc luding the endemic species Oryza rhizomatis. One recommended rice variety; Bg 352, fourteen O. rhizomatis accessions, and one accession from Oryza nivara, Oryza rufipogon,  Oryza granulata and Oryza eichingeri screened by the honeydew test. The experiment was arranged in a complete randomize d design with fifteen replicates with Bg 380 and Ptb 33 as susc eptible and resistant checks respectively. The lower amount of honeydew excretion recorded in all tested O. rhizomatis  accessions, O. nivara, O. granulata, and O. eichingeri accessions  suggested BPH resistance. Both Ptb 33 and O. rufipogon showed a similar level of resistance with low honeydew  excretion. The varieties Bg 352 and Bg 380 showed a high amount of honeydew excretions confirming higher susceptibility to the BPH. Therefore, all fourteen accessions of O. rhizomatis and the selected accessions of O. nivara and O. eichingeri are potential donors for rice breeding programs. Further, th e coding sequences (CDS) of known BPH genes of O. sativa were used as queries to search similar genes in wild rice genomes. The CDS coverage and phylogenetic analysis suggest, of known BPH resistance genes, at least BPH6, BPH9, BPH14-1, and BPH18 are present in O. rhizomatis, O. eichingeri, O. nivara, and O. rufipogon genomes. This information will assist in marker-as sisted breeding attempts. Published on 2022-03-30 00:00:00
  • Prevalence of Bovine Tuberculosis among Cattle and Buffaloes in the
           Central Province of Sri Lanka

    • Abstract: The Bovine tuberculosis (bTB) is a chronic disease condition in dairy cattle and a proven global zoonosis. This study was designed to identify the prevalence of bTB in dairy cattle and buffaloes in the Central Province (CP) of Sri Lanka. Single Intradermal Comparative Cervical Tuberculin (SICCT) test was performed in 20 farms (n=616 cattle and buffaloes) in three districts (NuwaraEliya; NE, Kandy; KN, and Matale; MT) in the CP. Out of the SICCT positive samples, randomly selected serum samples (n=33) of eight farms were subjected to the rapid antibody (Ab) test for further confirmation. Results were evaluated for different risk factors; age, sex, parity, body condition score (BCS), breed, herd origin, reproductive status, herd size, type of management, and duration of farm establishment. The prevalence of bTB among individual cattle and buffaloes was 22% with a 50% herd-level prevalence. In NE and KN, 34% and 19% of individuals showed positive reactions for SICCT, respectively, while all the individuals in MT were negative. There were significant statistical associations (P<0.05) were observed with the prevalence of bTB and BCS, breed, herd origin, and reproductive status; however, age, sex, parity, herd size, type of management, and duration of farm establishment were not statistically significant (P>0.05) with the prevalence of bTB.The conclusion is that, based on the SICCT test, the estimated prevalence of bTB in cattle and buffaloes in the central province of Sri Lanka is relatively high (>20%). The SICCT test could be recommended for the screening of the bTB in cattle and buffaloes in all regions of Sri Lanka to assess the island-wide prevalence of bTB, as this disease carries the risk of transmitting to humans and other susceptible animal species.

  • The Effect of Nutrient Management and Crop Rotation on Weed Dynamics in
           Rice under Dry Zone (DL1B) of Sri Lanka

    • Abstract: The Integrated weed management (IWM) is widely used to manage we eds in diverse cropping systems. Crop rotation and diverse n utrient management strategies are essential components in IWM. However, the effect of crop rotation and nutrient management systems on weed dynamics in Sri Lankan rice-based cropping systems is scarce. Therefore, an experiment was conducted to identify weed density, biomass, and abundance of two different nutrient management systems (Synthetic; SNM and Integrated; INM) and under rice monoculture and rice-maize rotation during four seasons within the  farm premises of the Faculty of Agriculture, Rajarata University of Sri Lanka. Rice variety Bg300 and maize hybrid Pacific-998 were cultivated. Growing maize in the Yala season increased  weed density and weed biomass compared to growing rice in both crop rotation cycles. During the first cycle, weed den sity was high under INM in the Rice crop phase. However,  in the second cycle, both crop phases (rice and maize) had low weed density under INM compared to SNM. A higher density of  sedges was reported with the crop rotation in the Yala season s, and grasses were dominant in the mono-cropping in both seasons. Grass biomass did not change with the nutrient manageme nt systems, while the biomass of sedges increased with synthetic fertilizer only. High weed density and biomass in maize during the first cycle were substantially reduced in the second cyc le for both nutrient management systems. Overall, reducing chemical fertilizer by 50% and incorporating organic matter, INM, substantially supported weed management in both rice and maize crops. Published on 2022-03-30 00:00:00
  • Evaluation of Clay Brick and Laterite Brick as Low-Cost Adsorbents for the
           Removal of Cd2+ and Pb2+ in Aqueous Solutions

    • Abstract: Adsorption is recognized as a low-cost and effective method for treating C admium and Lead in wastewater. Therefore, this study focu sed on investigating the potential of construction demolition wastes (CDWs), laterite bricks (LB), and clay brick (CB) to re move Cd and Pb in synthetic wastewater. A series of batch a dsorption experiments were conducted to study the adsorption characteristics and capacities. The results revealed that the ma ximum adsorption capacity of CB and LB reached 210.85 mg/g and 210.72 mg/g for Pb2+, respectively. The maximum adsorption capacity of Cd2+ by CB and LB was 4.52 mg/g and  4.51 mg/g. From adsorption isotherms, the Langmuir and Freundlich models fitted well for 0 ≤ Ci ≤ 1000 mg/L of Cd2+ adsorption on both CB and LB. Adsorption of Pb2+ onto CB and LB is well  captured by all isotherm models tested. A similar pattern of adsorption was observed among all particle sizes of CB and LB  (<0.5, 0.5-1.0, and 1.0–2.0 mm), indicating that the particle size  of tested adsorbents is not affecting the adsorption isotherms of Cd2+ and Pb2+. However, the particle size ranges used in this  study lay within a narrower range, which might be the reason  for not showing any difference in adsorption among the different size fractions. Therefore, it is concluded that both CB and  LB are effective and environmentally friendly adsorbents to remove Pb2+ and Cd2+in wastewater. Published on 2022-03-30 00:00:00
  • Pesticide Usage Pattern in Rice Cultivation in Trincomalee District in Sri

    • Abstract: Use of pesticides in Sri Lanka's rice cultivation has increased tremendously in the past decades. This study examined the current practices of pesticide use among randomly selected 174 farmers in the district of Trincomalee. A questionnaire survey and face-to-face interviews were conducted in 2019/2020 to collect primary data. The study revealed that 97% of farmers used herbicides, 70% used insecticides, and 4% used fungicides. Sixty three percent (63%) of the active ingredients of pesticides used were belong to class II (moderately hazardous), 31% belong to Class III (slightly hazardous) and 6% belong to Class U (unlikely to present acute hazard) according to WHO pesticides hazard categories. The most popular herbicide, insecticide and fungicide are Pretilachlor 30% EC (34%), Carbosulfan 200 g/L SC (36%), Tebuconazole 250 g/L EW (2%), respectively. Over 50% of farmers did not follow the guidelines recommended by the Department of Agriculture. 26% of farmers combine two or more chemicals to produce a mixture, as they believe such mixtures are more effective in controlling pests. Farmers are well aware about the bad effects of pesticides and the importance of protective gears but 63% of farmers did not use protective gears when applying pesticides. Violation of scientific recommendations, malpractice in the use of pesticides such as overuse, underuse, mixing and applying can be observed in the study area. Most of the user-level problems are related to farmers' attitudes. This study recommends educating the farmers on correct use of pesticides and monitoring the use of pesticides. It is proposed to take legal action against malpractices. Published on 2022-03-30 00:00:00
  • The Typology of Tea Smallholding Development Societies: Assessing Their
           Multifunctional Approach in Badulla District of Sri Lanka

    • Abstract: The Farmer-based organizations (FBO) have mechanisms to address the  collective issues of farmers. In the present socio-economic  context, the traditional approaches adopted by the FBOs to empower the farmers have been challenged by internal and extern al dynamics. The ‘Multipurpose Service Approach’ has been  proposed to address the broader needs of farmers. Tea Small Holding Development Societies (TSDS) were establishe d to work on the wellbeing of the tea smallholders. This study sought to identify the various activities carried out by TSDS in the Badulla district and classify TSDS based on adherence  to the Multifunctional service approach. Data were collected from twenty-one TSDS using structured interviews, selected by stratified random sampling technique. TSDSs' participatio n in the identified twelve activities was assessed using a 0-10 score method. Data were analyzed descriptively, using signs , the Man-Whitney test, and cluster analysis. TSDS in the Badulla district showed a different level of execution of multifunctions. When considering production support packages, the supply of inputs was at a satisfactory level (Score 6) in the  majority of TSDS. However, the role of the organization in linking the extension service with the members was not sa tisfactory. The provision of loans and other financial services wa s poor. Market-oriented activities were kept to a minimum. There was a lack of policy dialogue within the organizatio n. Based on the variability of the practicing of multifunc tional service approach, six clusters could be identified, including one with almost dormant TSDSs in many of the activities considered. Five other clusters had varying levels of engagement in different functions on certain aspects. The overall multifunctional service approach performances of TSDS were not satisfactory.

  • Effect of Water Stress during Seed Production and Storage Time on
           Germination and Seedling Growth of Cowpea Grown in the Dry Zone of Sri

    • Abstract: The water stress during the flowering stage of cowpea reduces the seed yield of the same season, but its effect on seed germination and seedling growth in the following season remains poorly understood. This study was carried out to determine the effect of soil water stress maintained during the onset of flowering stage and storage period of seeds on seed germination, vigor index, and seed physical characteristics of five cowpea varieties (Waruni, Dhawala, MI 35, ANKCP 01 and Bombay) in the following season in the dry zone of Sri Lanka. Seed production under well-watered and water-stressed conditions was done at the Field Crops Research and Development Institute (FCRDI), Mahailuppallama, in a Randomized Complete Block Design. The germination study was conducted in a polytunnel at the Faculty of Agriculture, Rajarata University of Sri Lanka, Anuradhapura, following the Completely Randomized Design. Seeds of five cowpea varieties produced after exposing the plants to two soil moisture levels (water stress: -50 kPa and well-watered: -30 kPa) were used in a series of germination trials conducted after 1, 1½, 2, and 2½ months of storage. Three hundred seeds from each genotype, randomly sub-divided into three replicates of 100 seeds each, were sown in sterilized sand media. Germination percentage was recorded on the 4th and 6th days after sowing. The seedling characters were assessed on the 6th day after sowing, using five randomly-selected seedlings from each replicate. The results revealed that the storage time significantly affected germination (p= 0.0133). However, the soil water status maintained during seed production did not affect the germination percentage of any variety in the following season. The majority of the varieties showed an increase in germination percentage with storage time. Although the vigor index did not change with either the well-watered or water-stressed treatments in all five varieties, the vigor index of all varieties declined with storage period irrespective of the water treatment (p< 0.0001). The findings suggest that moderate water deficits during cowpea seed production do not compromise seed germination and seedling vigor in the following season while emphasizing the importance of utilizing the seeds for subsequent field cultivation in the following season before their vigor is decreased.

  • Management of Sugarcane Smut Disease using Triazole Fungicides and
           Synthetic Elicitors

    • Abstract: Sugarcane smut caused by Sporisorium scitamineum is a devastating disease of sugarcane. As a management strategy, seed sets of resistant varieties treat with fungicides after the hot water treatment. As a novel management strategy, we evaluated the possibility of using low concentrations of fungicides and synthetic elicitors under in vitro and field conditions. Three fungicides (i.e. Tebuconazole, Hexaconazole, and Metalaxyl 8 % + Mancozeb 64 % WP) and two synthetic elicitors (i.e. salicylic acid (SA) and jasmonic acid (JA)) were tested in vitro at four concentrations (i.e. 250, 500, 750, and 1000 ppm) for their efficacy on inhibition of the germination of smut teliospores. Tebuconazole, Hexaconazole, and salicylic acids completely inhibited the germination of the teliospores at 500 ppm, 250 ppm, and 750 ppm concentrations, respectively. Metalaxyl 8 % + Mancozeb 64 % WP and JA inhibited the teliospore germination by 52 and 58 % respectively at 1000 ppm concentration. In the field evaluation, smut pathogen was artificially inoculated to the seed sets of a resistant (Co 775) and a susceptible variety (SL 88 116) treated with fungicides and SA at selected concentrations. Disease incidence (DI) was recorded, and disease severity (DS), Area Under Disease Progress Curve (AUDPC), and Percentage Reduction of the Disease (PRD) were calculated. Tebuconazole 500 ppm, Hexaconazole 250 ppm, Hexaconazole 500 ppm, and salicylic Acid 1000 ppm successfully controlled the disease significantly(P=0.05) in terms of DI, DS, AUDPC, and PRD, hence can be used as a dip treatment of seed sets to control sugarcane smut disease.
