Critical analysis of performance of Farmer Producer Organizations (FPOs) in Rayalaseema region of Andhra Pradesh
Farmer Producer Organizations enable member farmers to reap the benefits of economies of scale in purchase of inputs, marketing, processing and value addition to their produce. The findings of performance of FPO would help the FPO promoting agencies, NGOs and management of FPO to focus their efforts on further improvement of functioning and services provided by the FPO to its members. The results revealed that, the overall mean performance score related to functioning was good. Among five components related to functioning indicator, the performance of audit system was ranked first followed by performance of members representation group dynamics, infrastructural facilities and governance and management. Whereas the overall mean performance score related to services was average. Among five service components, the performance of technical services was ranked first followed by the performance of input services, financial services, marketing services, processing and value addition.
On Farm Evaluation of Balanced Fertilization on Productivity, Nutrient use Efficiency and Economics of Pre-dominate R-W Cropping System of Jammu Region
A field experiment was conducted at 24 locations (four farmers in a village, three villages viz., Kothimorh, Dabber and Chakbana of Bishnah and Shekhupur, Chakmajra and Chakkeema of Arnia in two blocks i.e. Bishnah and Arnia) to evaluate the effect of balanced fertilization on productivity, nutrient use efficiency and economics of Rice-Wheat predominant cropping system of Jammu district of J&K during 2017-18 to 2019-20. The Experiment was laid out in RBD design. Seven fertilizer treatments; Control (0-0-0), N alone (N-0-0), NP (N-P-0), NK (N-0-K), NPK (N-P-K), NPK + Zn (N-P-K-Zn), FP (Farmers Practices) were taken under study and the data revealed that the application of recommended dose of NPK +ZN realized the highest grain yield of rice 2916.14 kg/ha and wheat (2926.29 kg/ha) and productivity in terms of REY 5772.85 kg, system net returns Rs 133188 with B:C ratio of 3.16 in comparison to other treatments. However, the average partial factor productivity was observed in the order of NPK in Rice (97.20, 145.80 and 291.61) and in Wheat (29.26, 58.52 and 117.05 kg grain/kg) along with agronomic use efficiency of 54.86, 82.29 and 164.58 in rice and 15.47, 30.94 and 61.89 kg grain/kg of applied nutrient in wheat. And Nutrient response in rice (26.7 kg grain/kg) and wheat (28.23 kg grain/kg) was also observed in the plots fertilized with recommended dose of NPK+ Zn. Balanced application of N, P and K was found to increase the system productivity and nutrient use efficiency of Rice-Wheat cropping system.
Efficacy of Sulfoxaflor 12 % SC against aphid (Myzus persicae) in Potato
A field experiment was carried out at Agricultural Research Station, Kota (Rajasthan) during rabi-2017-18 & 2018-19 to evaluated efficacy of sulfoxaflor 12% SC against aphids viz., aphids (Myzus persicae). The various doses of sulfoxaflor 12% SC i.e. 175, 200, 225 and 450 ml/ ha (450 ml/ha only for phytotoxicity test) along with standard check thiamethoxam 25 % WG at 100 g/ha were evaluated against aphids of potato. The minimum population (0.95 & 0.75 and 1.46 & 0.96 aphids/plant) was recorded in sulfoxaflor 12% SC @ 225 ml/ha after 10 days of spray during 2017-18 & 2018-19, respectively and was statistically significant in compare to other treatments. It was followed by sulfoxaflor 12% SC @ 200 ml/ha and thiamethoxam 25% WG @ 100 g/ha. The highest mean tuber yield of 10.69 t/ha was recorded in sulfoxaflor 12% SC @ 225 ml/ha followed by sulfoxaflor 12% SC @ 200 ml/ha. The different doses of sulfoxaflor 12% SC i.e. 225 and 450 ml/ ha did not cause any phytotoxicity symptoms to potato crop besides this all treatments of insecticides not differ significantly population of natural enemies during study period.
A comparative study on nutritional and functional composition of fresh apple pomace and dried apple pomace powder
Apple pomace is considered a major by-product of apple juice processing, which is generated in several million metric tons worldwide every year. Due to its low recovery rate, it is generally disposed of as waste, resulting in various public hazards and environmental pollution. However, it is a rich source of numerous nutritional and functional compounds such as carbohydrates, phenolic compounds, dietary fibre, minerals, and, organic acids. Therefore, this study was undertaken to study the nutritional and functional composition of fresh and dried apple pomace powder to explore its possibilities of usage in the food industry. The fresh pomace and dried apple pomace powder were subjected to various physio-chemical analysis such as bulk density, tapped density, flow ability (Carr Index), cohesiveness (Hausner ratio), carbohydrates, energy value, total polyphenols, antioxidant activity and, hydration properties. While, the functional characterization was obtained by Fourier Transform Infrared Spectroscopy (FTIR) analysis. The comparative analysis revealed that the moisture content decreased from 80.04% to 8.23 percent, while, the ash content, fat, fibre, protein, carbohydrates, energy value, ascorbic acid, total phenols and antioxidant activity increased significantly from 1.12 to 2.06 percent, 0.63 to 2.39 percent, 4.65 to 20.68 percent, 0.81 to 3.12 percent, 12.75 to 63.52 percent, 12.75 to 290.25 kcal/100g, 6.15 to 12.21 mg/100g, 95.26 to 451.14 percent and 75.21 to 85.37 percent, respectively. Moreover, the FTIR analysis confirmed the presence of carbohydrates, fats, proteins, water, phenols and identified various functional compounds including quinones, organic matter, ethers, lignin, aromatic compounds, oxy compounds and disulphides, etc.
Indian Potato Markets Linkage and Impulse Response of Price Shocks
Potato is the most cultivated vegetable accounting for 27 per cent of the total production of vegetables in the country. Production of potato in the country during 2019-20 is estimated around 20.73 lakhs ha and 519.47 Lakh Tonnes. It is always quoted that potato suffers from a significant price volatility across spatial and temporal dimensions. This paper objectively examines the potato price shocks transmission and time to adjust the shocks from other markets. The analysis is based on time series monthly data on prices of potato for four major markets viz. Agra, Allahabad, Farrukhabad and Kanpur of Uttar Pradesh. Vector autoregression (VAR) and VAR impulse response analysis was employed to examine the potato price shock response between the markets. The study revealed that when the shock is given to any market, the responses of all other markets disappear between 6 to 10 months. Agra market emerged as a prominent market which influences the price of potato in other markets.
