INFLUENCE OF SUPPLEMENTARY FOLIAR SPRAY OF UREA AND BORON ON THE GROWTH AND YIELD OF CHICKPEA VARIETIES

Abstract

A field experiment was conducted at the Agronomy research field, Sher-e-Bangla Agricultural University, Dhaka, during the period from November, 2016 to April, 2017 to study the influence of supplementary foliar spray of urea and boron on the growth and yield of chickpea varieties. The experiment was carried out in split plot design considering two varieties i.e. BARI Chola-5 and BARI Chola-8 in the main plot and five levels of supplementary foliar spray viz. T = Recommended fertilizer (RF), T 2 1 = RF + Foliar spray (FS) of water at flower initiation (FI), T = RF + Urea (2%) FS at FI, T 4 = RF + Boron (1%) FS at FI, T = RF + Urea (2%) + Boron (1%) FS at FI in the sub plot replicated three times. Variety 5

3 BARI Chola-8 (V ) gave the highest above ground dry matter plant -1 (11.95 g), pods plant -1 (26.11), 1000 seed weight (273.87 g) and seed yield (1.47 t ha -1 ). In the case of supplementary foliar spray, highest above ground dry matter plant -1 (12.82 g), pods plant (28.27), seeds pod -1 (1.92), 1000 seed weight (220.90 g) and seed yield (1.69 t ha -1 ) was produced by T treatment (RF + 2% Urea FS at FI). Regarding combined effects, the highest pods plant 3 -1 (29.17), 1000 seed weight (298 g) and seed yield (1.75 t ha -1 ) were observed from V 2 T 3 (BARI Chola-8 along with RF + Urea (2%) FS at FI) when V (BARI Chola-5 along with RF + Urea (2%) FS at FI) was significantly at par for pods plant

and seed yield. So, BARI Chola-8 or BARI Chola-5 cultivation with recommended fertilizer plus additional 2% urea spray at flower initiation may be a way of maximizing yield of chickpea.
