Nitrogen metabolism enzymes activity in flag leaf and roots of pearl millet during grain development stage
Get PDFNitrate reductase (NR), Glutamine synthatase (GS), Glutamate dehydrogenase (GDH) and Aspartate aminotransaminase (AspAT) were assayed in flag leaves and roots of four pearl millet genotypes, started from ear emergence till grain maturity at four days intervals. All enzymes showed higher activities in flag leaf than that of roots irrespective of growth stage and genotypes. A slight increase in flag leaf NR, GS and AspAT activity till anthesis started decreasing while GDH increased till 12 days after anthesis (DAA) and almost constant till 18 DAA and then started decreasing. While in roots a steep declining trend was observed in NR, GS and AspAT and reached to almost non-detectable level till maturity while GDH increased up to 6 DAA and then decreased sharply irrespective of the genotypes. The almost stable GDH activity and decreasing trend in NR, GS and AspAT suggested that re-assimilation of amino nitrogen takes place in flag leaf instead of direct assimilation from the roots for nitrogen deposition in pearl millet developing grains
Application of hazard and critical control point analysis (HACCP) in organic farming
Get PDFThe primary purpose of this discussion paper on the integration of food safety management systems based on the Hazard and Critical Control Point Analysis (HACCP) with organic certification was to inform those within and outside the organic industry of recent developments in this area. It is also intended to highlight the need for the organic industry to address food safety management as part of the organic certification process. During the past two years, legislation and international demand in the marketplace for food safety management (complete with verification of the use of these systems) has led to a situation where it has become more a matter of ‘how’ than ‘if’
Application of smart phone agro-advisory services of m4agriNEI in climate smart natural resource management in agriculture by tribal farmers of Meghalaya: an empirical study with structural equation modeling
Get PDFSmart phone applications are increasingly being used by farmers of North East India to help them make informed decision on Climate-Smart Natural Resource Management (CSNRM). The research project m4agriNEI is an innovative mix of Smart Phone and web applications along with Toll Free IVRS based farmer specific agro-advisory system being implemented at College of P.G. Studies in Agricultural Sciences of CAU, Imphal at Umiam, Meghalaya in collaboration with Digital India Corporation, New Delhi. The present study aims to investigate and confirm a successful model application of smart phone Agro-Advisory Services (AAS) by the registered farmers of m4agriNEI by incorporating five constructs through Structural Equation Modelling on CSNRM in Agriculture. Survey research design was followed in the study by incorporating exploratory and confirmatory factor analysis. A total of 363 registered farmers were treated as respondents in the study. The study unveiled that ‘Smart Phone Agro-Advisory Services Acceptance Model’ of m4agriNEI is a successful model on empowering the tribal farmer of Meghalaya in climate smart natural resource management in agriculture by providing right information in right time through a smart phone based agro-advisory system
Cost benefit ratio of bio-control agents, botanicals and fungicide in the management of white rot of onion caused by Sclerotium rolfsii Sacc. in Manipur
Get PDFThe research investigation was undertaken to evaluate the economics of the management of white rot of onion by Trichoderma harzianum, Trichoderma viride, garlic (Allium sativum L.), turmeric (Cucurma longa L.), sweet flag (Acorus calamus L.) and Carbendazim (50% WP). Carbendazim recorded highest gross return followed by T. harzianum and T. viride respectively. Carbendazim also recorded highest net return followed by T. harzianum and garlic respectively. Among the treatments, Carbendazim gave the highest net return cost benefit ratio of 1:3.25. Garlic extract gave cost benefit ratio of 1:2.96. T. harzianum gave cost benefit ratio of 1:2.89
Studies on the nutritional properties of neem (Azadirachta indica) leaves at Pantnagar area of Uttarakhand
Get PDFThe present work was carried out to study the nutritional properties of neem (Azadirachta Indica) leaf powder collected from Pantnagar area. Equal quantity of neem leaves were collected from three different places such as College of Veterinary and Animal Science (C.V.A.Sc.), Instructional Poultry Farm (IPF) and Instructional Dairy Farm (IDF) inside the campus of G.B. Pant University of Agriculture and Technology Pantnagar. The leaves powder was prepared for proximate analysis i.e. Dry matter (DM), Crude Protein (CP), Ether Extract (EE), Total Ash (TA), Crude Fiber (CF), Calcium (Ca) and Phosphorus (P). Present study indicated that the neem leaf powder pre-pared from the leaves collected from Instructional Poultry Farm (IPF) have higher dry matter, crude protein and ether extract, whereas the value of calcium and phosphorus were found more in the leaves collected from College of Veterinary and Animal Science. So it can be concluded that neem leaf powder collected from Instructional Poultry Farm (IPF) can be included in the diet of the poultry for getting optimum results in growth performance, carcass characteristics, haematological, biochemical and immunological aspects
