GROWTH AND YIELD OF CHICKPEA AS INFLUENCED BY DIFFERENT MICRONUTRIENTS

Abstract

An experiment was conducted at the research field of Department of Agronomy, Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2011 to March, 2012 to find out the influence of the different micronutrient application to chickpea crops for increased seed yield. The treatment were designed with two factors i. Cultivars; V = BARI Chola-6 and V 2 = BARI Chola-9 and ii. Micronutrient application; F 1 = Control (No fertilization), F 1 0 = Recommended NPK + all (B,S,Zn,Mg) +Zypsum in soil, F = Recommended NPK + B,S,Zn,Mg (Sprey), F =Recommended NPK + 3 without B (Sprey), F 4 3 = Recommended NPK + 3 without S (Sprey), F = Recommended NPK + 3 without Zn (Sprey), F 6 5 = Recommended NPK + 3 without Mg (Sprey). The experiment was laid out in randomized complete block design with three replications. Results revealed that cultivars had significant effect on yield attributes and yield of chickpea. BARI Chola-6 gave maximum pods plant (30), 1000-seed weight (117.44 g), harvest index (43.97%) as well as seed yield (1.72 t ha -1 ) whereas BARI Chola-9 which showed lowest grain yield. In case of micronutrient application, significant variations were observed in yield attributes and yield of chickpea. F 1 () gave higher pods plant -1 (45.98), 1000 2 -1 seed weight (122.3 g), harvest index (46.39%) as well as seed yield (2.19 t ha ) while control gave minimum yield. Out of 14 treatment combinations, BARI Chola-6 cultivated with Recommended NPK + all (B,S,Zn,Mg) +Zypsum in soil performed the best results in terms of growth and yield. The maximum pods plant -1 (55.57), seeds pod -1 (2.21), 1000-seed weight (124.3 g), harvest index (48.45 %) as well as seed yield (2.51 t ha () minimum results. -1 ) were recorded in V 1 F 1 () while V 2 -1 F 0
