Abstract:
A field experiment was carried out in a loamy sand soil at Rajasthan Agricultural Research Institute, Durgapura during Rabi seasons of 2021-22 and 2022-23 to study the effect of irrigation scheduling and nitrogen management on yield and yield attributes of wheat. Wheat (cv. Raj 4083) was grown in a split plot design with four irrigation scheduling (0.6 IW/CPE, 0.8 IW/CPE, 1.0 IW/CPE & at critical growth stages) as main factor and five nitrogen management strategies (Control, 100% RDN through FYM, 50% RDN through FYM + 2 foliar spray of nano urea, 100% RDN through chemical fertilizer & 50% RDN through chemical fertilizer + 2 foliar spray of nano urea) as subplot factor. It was observed that number of effective tillers/m², number of spikes/plant, number of grains/spike, weight of spike/plant, test weight and yield of wheat was statically higher with an irrigation scheduling 1.0 IW/CPE. The maximum yield attributes and grain yield of wheat was recorded with 100% RDN through chemical fertilizer over other doses of nitrogen.
