Abstract:
In the present investigation, we investigated the effects of conservation tillage and nutrition levels on productivity, profitability, and nutrient uptake of wheat (Triticum aestivum L.) during rabi season of 2020-21 at the Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U.P., India. Soil of the experimental plot was sandy loam in texture, medium in organic carbon and available NPK with neutral pH (7.4). Experiment was laid out in split-plot design with three replications. The main plots consisted of four crop establishment methods, i.e. Furrow Irrigated Raised Beds, Roto tillage, Reduced tillage, and Conventional tillage and six nutrient levels viz. Control, 100% RDF, 100% RDF + NPK consortia + Bio-stimulant, 75% RDF + NPK consortia + Bio-stimulant, 100% RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray after II irrigation, and 75% RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray after II irrigation were allotted in sub-plot. Results revealed that among the tillage methods, yield of wheat (grain, straw, and biological qha-1) differ significantly. Treatment furrow irrigated raised beds was recorded 21.21, 9.96 and 14.24% more grain, straw, and biological yield, respectively over conventional flood irrigation. Among the nutrition levels, after II irrigation, the crop fertilized with 100 percent RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray had the most effective tillers m-1 (156.21), ear length (12.40 cm), number of grains per spike (49.66), grain yield kg ha-1 (4751), and test weight (40.12g) in comparison to the prescribed NPK nutrition management method, the number of effective tillers m-1 was 127.17, the ear length was 7.20 cm, the number of grain per spike was 37.91, the grain yield kg ha-1 was 3214kg/ha, and the test weight was 36.23g.The crop fed with 100% RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray after II irrigation and 100% RDF + NPK consortia + Bio-stimulant recorded highest nitrogen, phosphorus and potassium content in grain as 1.62 & 1.64%, 0.31 & 0.31% and 0.68 & 0.70% while in straw as 0.56 & 0.59%, 0.11 & 0.12 % and 1.33 & 1.35%. Higher nutrient uptake (NPK) by grain and straw as well as total uptake were recorded under furrow irrigated raised beds followed by roto tillage and reduced tillage. Cost of cultivation, being lowest in control plots which ranged between Rs. 27324ha-1 while highest cost of Rs. 34795 and 35803 ha-1 was incurred with the application of 100% RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray after II irrigation and 100% RDF + NPK consortia + Bio-stimulant. Therefore, tillage methods sowing of wheat on FIRB with application of 100% RDF + NPK consortia + Bio-stimulant + NPK (18:18:18) spray after II irrigation were proved the most ideal approach to achieve the higher productivity, profitability and nutrient uptake under the irrigated ecosystem of Uttar Pradesh.
