A talk on ‘4R nutrient stewardship in perennial crops’ by Dr. A. K. Srivastava, Pr. Scientist, ICAR – CCRI, Nagpur
A talk on ‘4R nutrient stewardship in perennial crops’ was delivered by Dr. A. K. Srivastava, Pr. Scientist, ICAR – CCRI, Nagpur at ICAR-CCARI, Old Goa on 30th May 2016 at 11.00 am. He has extensively pursued research work on different aspects of citrus nutrition like nutrient constraints analysis of citrus orchards by developing DRIS-based soil-plant nutrient diagnostics, orchard efficiency modelling, targeted yield-based site specific nutrient management exploiting spatial variability in soil fertility, citrus rhizosphere specific microbial consortium and soil carbon loading, INM module, fertigation scheduling, nutrient mapping using geospatial tools, nutrient dynamic studies, transformation of soil microbial biomass nutrients within citrus rhizosphere and soil fertility map as decision support tool for fertilizer recommendation.
Dr. Narendra Pratap Singh, Director, ICAR-CCARI welcomed Dr. A. K. Shrivastava and explained the importance of the new concepts of nutrient management like 4R stewardship with respect to west coast region of India. Dr. A. K. Shrivastava talked about development of soil test crop response based fertilizer recommendations to the perennial crops, use of microbes and microbial consortia for plant growth promotion, leaf testing based fertilizer recommendations, etc. He urged the need for development of the newer and faster diagnostic tools for leaf tissue testing e.g. spectroscopy based nutrient detection. The programme was attended by scientists, technical staffs and KVK staff of this Institute.
