EFFECT OF NITROGEN AND BORON ON GROWTH AND YIELD OF CHICKPEA (Cicer arietinum L.)

Abstract

An experiment was carried out at the experimental field of Sher-e- Bangla Agricultural University(SAU), Sher-e-Bangla nagar, Dhaka-1207 during the period from November 2018 to April 2019. A set experiment was conducted of two different factors viz. Factor A: Nitrogen fertilizerlevel-3; i) N 0 = No nitrogen (Control) ii) N 1 = 25 kg ha = 35 kg ha 1 -1 and factor B: Boron fertilizer level-3; i) B and iii) B 2 = 1.5 kg ha -1 0 = No Boron (Control) ii) B . The experiment was laid out in Randomized Complete Block Design (RCBD) with three replication. The data on plant growth characters, yield contributing characters and harvest index were analyzed using analytical computer software program statistix-10. The mean differences among the treatments were compared by least significant difference test at 5% level of significance. Experimental results revealed that application of nitrogen in 25 kg ha -1 -1 )showed best performance in terms of higher yield and yield contributing characters viz.number of branch plant -1 (24.38), pod length(1.91cm), effective pod plant -1 and iii) N (N 1 1 (39.04), pod plant (45.35), seed pod -1 (1.90), 1000-grain weight(151.64 g), grain yield(2.14 t ha ) and straw yield(2.31t ha -1 ). whereas the lowest results were recoreded in without nitrogen (N ). 1.5 kg ha -1 (B 2 ) boron application showed higher results on branch plant -1 (25.17), height pod length(1.75cm), effective pod plant -1 (40.96), pod plant -1 (47.03), seed pod (1.93), 1000grain

weight 1 (153.45g), grain yield(2.19 t ha -1 ) and straw yield(2.37 t ha )over no boron application (B ). The finding of present research work suggest that application of nitrogen in 25 kg ha -1 0 (N 1 )and 1.5 kg ha -1 (B ) boron application can be practices to chickpea cultivation. Among the interactions N 2 1 B demonstrated the best performance considering branch plant 1 -1 (25.17), branch plant (44.66), pod plant -1 -1 2 -1 -1 -1 2 = 1.0 kg ha (26.37), pod length(2.02cm), effective pod plant (50.36), seed pod -1 (2.05), 1000-grain weight(158.31g), grain yield(2.37 t ha -1 ) and straw yield(2.51 t ha -1 )can be for up lifting grain yield of chickpeain the salt Bangladesh.
