Indigenous Bacteria for Increasing the Shelf Life of Seaweed (Caulerpa lentillifera) in Laboratory Scale
The optimum of culture time and concentration of alginate for antimicrobial activity of both potential strain L18 and L8 were carried out for 12h, 24h, 36h, 48h, 60h, 72h, 84h, 96h, 108h and 120h by agar well diffusion method. The cultured broth of two best parameters in the previous experiment was designed as bio-products for application on preservation of sea grapes after harvesting. The effectiveness of those bio- products was expressed in the number of pathogenic bacteria counted. The physiological state of sea grapes was reliably evaluated with a diving pulse-amplitude-modulation fluorometer quantifying the chlorophyll fluorescence parameter of maximum quantum yield of photosystem II (PSII, Fv/Fm). Results showed strain L8 was strongly inhibited against Pseudomonas sp. A1 and Klebsiella variicola S1 after 36h cultivation whereas the strain L18 was most inhibition Pseudomonas sp. A1, Enterobacter sp. T1, Citrobacter freundii A2 after 60h cultivation. The concentration of alginate which was the most effective for antimicrobial activity of L8 was 0.3% and L18 was 0.2%. The bio-products added treatments showed a lower number of pathogenic bacteria from 1000 to 10000 times than those in the control samples. Bio-products treatments had not shown significant differences in total phenolic content and chlorophyll-a. In addition, the data from PSII measurement showed that two treatments L8 plus 0.3% alginate and L18 plus 0.2% alginate yielded much better productivity of PSII than other two control samples. The shelf life of edible seaweed could be increased up to 10 days at room temperature, when it was sprayed with bio-products.
Linking Actors Related-Stakeholders By Applying Network Analyses In Promoting Economic Advantages of The Goat Business In West Papua
The goat has been taking the places on farmers' needs just recently due to its products, i.e. slurry. It has brought a significant impact on economic advantages for small farmers. Those are due to stakeholders’ involvement in promoting its development. The study was done in Manokwari using the descriptive method by using focus group discussion towards twenty various represented individuals, groups, and mass institutions. The queries discussed concerning the background, resources delivery, inter connectivity among actors using Pearson correlation coefficient and similarity matrix, power, and interest of actor’s delivery of intervention and innovation of actors. The goat farming system in West New Guinea is shaped by related groups, lawyers, privates, and stakeholders rather than shareholders. The actors are important and have a positive effect. The actors have a low direct threat and slight high turn back effect. The four top shared resources consist of access, satisfaction, time, and space. The actors have a willingness to contribute in a long-term period and can sustain their support. However, the power of resources shared is neutral and therefore needs further intervention. The relationship of SNA is showing a relationship of similarity and with a greater positive correlation of each actor due to high interest and high power. The five top intervention for goat farming system is skills, feed materials, policy, funds, and satisfaction. While innovation needed by actors are skills, policy, knowledge, feed materials, and fund.
Effect of LCC based nitrogen application on nutrient uptake and use efficiency in wheat under irrigated sub tropics of Jammu
A two-year field experiment was conducted to investigate the effect of leaf colour chart (LCC) and chlorophyll meter (SPAD meter) based nitrogen fertilization on nutrient uptake, use efficiency and productivity of wheat crop under irrigated sub tropics of Jammu. The investigation conducted at Divisional Research Farm of Agronomy, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus Chatha during Rabi 2018-19 and Rabi 2019-20. Experiment was laid out in randomized block design with four replications and six treatments viz. control, nitrogen application based on LCC ≤ 3, nitrogen application based on LCC ≤ 4, nitrogen application based on LCC ≤ 5, sufficiency index based nitrogen application and recommended dose of fertilizer (100:50:25:37.5 kg/ha N:P2O5:K2O:S) along with well fertilized reference plot with 150 per cent recommended dose of nitrogen (150:50:25:37.5 kg/ha N:P2O5:K2O:S) for calculating sufficiency index. Among different treatments of nitrogen management, significantly highest yield and nutrient uptake were recorded with LCC ≤ 5 based nitrogen application. However, sufficiency index based nitrogen application recorded numerically higher nitrogen use efficiency and apparent recovery of nitrogen whereas recommended dose of nitrogen application recorded maximum physiological efficiency.
Dissipation Patterns and Effect of Household Processing on Lowering of Tebuconazole Residues in Chili and Soil Using GC-MS/MS
The issue of food safety and food security are the two key aspects in our country. Also the food we consume is safer or not is the most important topic of concern now-days. In order to estimate the potential risks due to pesticide exposure from food, it is required to evaluate the level of exposure at the time of consumption. The aim of this study conducted during 2016-17, was to assess the level of Tebuconazole (Folicur 25.9EC @ 125 and 250 g a.iha−1) residues in chili fruit. Gas chromatography-tandem mass spectrometry (GC-MS / MS) was used to analyze collected samples. Residues dissipated with time showing a half-life of 1.61 days at a single dose and 2.19 days at double dose after kinetics of first order. The processing is very efficient in reducing tebuconazole residues in chili fruits. By washing with tap water, tebuconazole reduction ranged from 55.71 percent to 30 percent. While the percent reduction of residues on washing with NaCl solution was in the range of 72.38 to 33.33 percent. Results indicate that washing with NaCl solution as better household practice for reducing the residues in the chili fruits for consumption purpose.
SMART AGRICULTURAL PRACTICES FOR SUSTAINABLE AGRICULTURAL PRODUCTION
Integrated management practices offer optimum use of land and farm resources through combination of various climate smart agricultural practices and other improved farming practices at common platform. However, there exists a major concern of their awareness level among farmers which ultimately leads to low level of adoption among the farmers particularly in situation like Haryana where small and marginal land holdings farmers are dominated. The data were collected from Haryana state of India with the help of well- structured and pre-tested interview schedule and analysed with Statistical Package for the Social Sciences. Research findings concluded that farmers awareness level was observed to be the highest about the INM increase the crop yield with weighted mean score (WMS) 2.02, excessive pesticides use is hazardous (2.03), weeds compete for light, water and nutrients (2.14), integrated farming system helps to reduce the cost of production (1.91), organic farming reduces input cost and enhances food quality (2.36), zero tillage reduce the field preparatory, labour and fuel costs (1.78), information and communication technologies provide information accurately, frequently and timely (1.64), e-marketing promote the cashless transaction (1.88), and crop insurance minimize the risk of crop failure (2.28). Hence, it is suggested that sincere efforts by government are required for promotion of such eco-friendly and sustainable practices in the country.
