Assessment of wheat production potential under different tillage and precision nutrient management

Abstract: Field experiments were carried out to assess the wheat production potential under different tillage and precision nutrient management at D3 Block of Norman E. Borlaug Crop Research Center in Govind Ballabh Pant University of Agriculture and Technology, Pantnagar at Uttarakhand, India, during the rabi season of 2015-16 and 2016-17. The experiment was laid out in strip plot design with three replications. Conventional tillage, reduced tillage and zero tillage practices were taken in horizontal strips while in vertical strips precision nutrient management practices like- control, recommended dose of fertilizer, site specific nutrient management and SSNM + Green Seeker, were taken. Test crop was wheat, variety DPW 621-50. Study revealed that significant increase in yield was recorded in reduce tillage over zero tillage while it showed at par results with conventional tillage in both the year. In precision nutrient management in year 2015-16 RDF showed significant increase of 89.6% and 10.2% in yield over control and SSNM+GS, respectively but was at par with SSNM treatment. Similar trend was followed in second year the increase in yield in RDF over control and SSNM+GS were 93.0% and 8.8%, respectively. Biological yield was significantly higher in reduced tillage in year 2015-16 while in year 2016-17 reduce tillage gave at par yield with conventional tillage but significant higher over zero tillage. In precision nutrient management higher biological yield was recorded in RDF treatment which at par with SSNM, SSNM+GS in year 2015-16 and SSNM in year 2016-17. Tillage and precision nutrient management practices failed to have significant effect on harvesting index in both the year. All the yield contributing characters like spike m-2, spike length, grains/spike 1000-grain weight in both the year were found maximum in reduced tillage and RDF nutrient management practice.
