Abstract:
A field experiment carried out at Agricultural Research Station, Brinjhagiri, Chatabar of Faculty of Agricultural Sciences, Siksha ‘O’ Anusandaha (Deemed to be University), Bhubbaneswar, Odisha during rabi season of 2018 and 2019. The experiment was laid out in randomised block design with eight treatments viz. T₁: Control, T₂: RDF (20: 40: 20 kg N, P₂O₅ and K₂O ha^-1), T₃: RDF + 2% Urea spray; T₄: RDF + 2% MOP spray; T₅: RDF + 2% DAP spray, T₆: RDF + 2% NPK 19:19:19 spray; T₇: RDF + 40 ppm NAA spray; T₈: RDF + 1% Salicylic spray, replicated 3 times. The test variety was Mahuri (OBG 31). The result revelled that foliar application of urea, DAP, MOP, NPK 19:19: 19, NAA and salicylic acid have positive increment over sole RDF. With 2% spray of NPK 19:19: 19 in addition to RDF (20: 40: 20 kg N, P₂O₅ and K₂O ha^-1 ) higher growth attributes were recorded. This treatment also produced the highest yield of 988.4 kg and 1053.3 kg per ha in 2018 and 2019 respectively. The highest NPK uptake was also calculated in the same treatment for both the years. Economically 2% foliar application of DAP along with RDF (20 kg N, 40 kg P₂O₅ and 20 kg K₂O kg ha^-1) found to be the best, with a return of Rs 1.85 and Rs 2.02 by investing a rupee for the respective year.
