Yield Performance of Mungbean Varieties under the Influence of Foliar Application of Urea and Boron

Abstract

The experiment was carried out in pre-kharif 2018 at Sher-e-Bangla Agricultural University in Dhaka to assess the effectiveness of foliar urea and boron spraying on mungbean.Two varieties viz. V1 = BARI Mung-5 and V2 = BARI Mung-6 and eight levels of fertilizer management viz. T1 = Recommended dose of fertilizer (RDF), T2 = RDF + Foliar spray (FS) of water at flower initiation (FI), T3 = RDF + Urea (2%) FS at FI, T4 = RDF + Boron (1%) FS at FI, T5 = RDF + Urea (2%) + Boron (1%) FS at FI, T6 = Urea (2%) FS at FI, T7 = Boron (1%) FS at FI and T8 = Urea (2%) + Boron (1%) FS at FI, were tested in a split-plot design with three replications. According to the results, BARI Mung-6 performed better than BARI Mung-5 across the majority of growth and yield metrics. The fertilizer treatments that had the maximum seed yield (1121 kg ha⁻¹), stover yield (1467 kg ha⁻¹), and harvest index (43.31%) were RDF mixed with urea (2%) and boron (1%) foliar spray (T5). Yield components, and biological yield (2631 kg ha⁻¹) were significantly improved by the combination of BARI Mung-6 and T5. Therefore, for better mungbean yield, BARI Mung-6 with RDF + urea (2%) + boron (1%) foliar spray at flower initiation is advised.
