EFFECT OF BORON FERTILIZATION ON WHEAT UNDER INORGANIC AND INTEGRATED NUTRIENT MANAGEMENT

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University, Dhaka during the period from November 2015 to March 2016 to study the effect of boron fertilization on wheat under inorganic and integrated nutrient management. BARI Gom-24 (Prodip) was used as plant material. Six treatments were considered for the experiment viz. T = Control (no fertilizer application), T 1 0 = 120 kg N, 30 kg P, 90 kg K, 20 kg S, 1.5 kg Zn ha = 120 kg N, 30 kg P, 90 kg K, 20 kg S, 1.5 kg Zn ha -1 + 1.5 kg B ha -1 , T = 120 kg N, 30 kg P, 90 kg K, 20 kg S, 1.5 kg Zn ha -1 + 3.0 kg B ha -1 , T = 70% NPKSZn from Inorganic fertilizer + 5 ton compost ha -1 + 1.5 kg B ha 4 -1 3 -1 and T = 70% NPKSZn from Inorganic fertilizer + 5 ton compost ha -1 , T + 3.0 kg B ha . The experiment was laid out in Randomized Complete Block Design with three replications. Results showed that the highest number of tillers plant (4.05), dry weight plant -1 (37.96 g), spike length (11.60 cm), number of grains spike

(38.43), 1000 seed weight (52.64 g), grain yield (4.28 t ha -1 ), Stover yield (5.60 t ha -1 ) and harvest index (43.32%) were found from T (120 kg N, 30 kg P, 90 kg K, 20 kg S, 1.5 kg Zn ha -1 + 1.5 kg B ha -1 2 ) treatment where control treatment, T 0 (no fertilizer) gave the lowest results for all parameters. 5 -1 2 -1 -1
