Abstract:

An investigation was carried out to calibrate the soil test based balanced fertilizer doses with farm yard manure for wheat under high density planting system during rabi season 2016-17. Available nitrogen, phosphorus and potash before planting ranged between 197.6-257.2, 10.2-35.0 and 307.4-467.5 kg ha-1, respectively. The larger proportion of variation (about 91%) in grain yield of wheat was accounted for fertilizer nitrogen alone. About 95 % of the grain yield variations were estimated due to fertilizer N and P only. The amount of nutrients required to produce one quintal of grain was found to be 2.00 kg N, 0.54 kg P and 1.91 kg K. The fertilizer efficiencies of N, P and K for high density wheat crop were estimated as 34.4, 22.0 and 72.1 per cent, respectively. The efficiencies of soil test for high density wheat were as 13.08 % N, 65.02 % P and 7.98 % K. The efficiencies of farm yard manure were observed as 13.7, 5.6, and 8.0 per cent for N, P and K. respectively. Based on these basic parameters viz. nutrient requirement, efficiencies of fertilizer, soil test and farm yard manure, fertilizer adjustment equations and a readyreconer were evolved which is useful to achieve a definite yield goal of wheat crop under high density planting system in similar soil and agro-climatic conditions.
