Description Thesis-PhD
Agricultural sustainability implies an increasing trend in per capita productivity to meet the present needs without jeopardizing the future potential. This demands an appropriate method of land and nutrient stewardship for the development of sustainable agricultural systems. Soil tillage and nutrient management influences agricultural sustainability through its effects on soil processes, soil properties, and crop growth & development. In this prospect the present investigation was carried out during rabi seasons of 2009-10 and 2010-11 at Norman E. Borlaug Crop Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, entitled “Nutrient Management in Wheat under various Tillage system after transplanted Rice”. The experiment was laid out in split-plot design with three main-plot treatments i.e. three tillage methods (viz zero tillage, conventional tillage and subsoiling) and five sub-plots i.e. nutrient management options (viz, FP, GRD, STCR target @ 40 q ha-1, STCR target + FYM @ 10 tone ha-1, SSNM) with three replications. The observations were recorded on growth and physiological parameters (Plant height, flag leaf area and relative leaf water content), yield (grain, straw and biological) and yield attributing observations (spike
length, no. of spike, grains per spike and thousand grain weight) and nutrient study of soil and plants (available N, P and K, its uptake and total uptake) under different tillage and nutrient management options. The tillage methods and nutrient management options had significant influence on yield & yield attributing characters and nutrient study of soil and plants. The average grain, straw, biological yield and plant nutrient uptake in wheat showed highest records under conventional tillage method and STCR target + FYM nutrient management option. Economics of an experiment showed that the cost of cultivation was higher under subsoiling and GRD treatment, whereas, gross and net monetary returns were higher under conventional tillage and STCR target + FYM and SSNM treatment respectively. The Benefit: Cost ratio was also higher under conventional tillage and STCR target + FYM nutrient management treatment.
