EFFECT OF NITROGEN AND ZINC ON GROWTH AND YIELD OF BARI CHHOLA-2 (Cicer arietinum L.)

Abstract

This experiment was conducted at the Sher-e-Bangla Agricultural University farm, Dhaka, during the period from November, 2015 to April, 2016 to study the effect of nitrogen and zinc on growth and yield of chickpea (Cicer arietinum L.). In experiment, the treatment consisted of four Nitrogen levels viz. N 0 = No nitrogen (Control), N 1 = 10 kg ha -1 , N 2 = 20 kgha -1 , N 3

and three Zinc levels viz. Zn 0 = No Zinc (Control), Zn 1 = 4.0 kgha = 8.0 kgha -1 . The experiment was laid out in a two factors randomized complete block design (RCBD) with three replications. The collected data were statistically analyzed for evaluation of the treatment effect. Results showed that a significant variation among the treatments in respect of majority of the observed parameters. The tallest plant was found in the 20 kg N ha . The maximum number of branches plant -1 , pods plant -1 was recorded from the 20 kg N ha -1 . The highest seed yield (2.10 ton ha -1 ) was recorded from the 20 kg N ha -1 . The highest plant height was produced from 8.0 kg Zn ha . The highest number of branches of chickpea, number of pods plant -1 was obtained from 8.0 kg Zn ha -1 treatment. It was observed that the 8.0 kg Zn ha treatments produced the highest seed yield (2.08 t ha -1 ). Significant variation was observed on the seed yield of chickpea due to various treatment combinations of N and Zn. It was observed that the treatment combination of 20 kg N ha 8.0 kg Zn ha -1 produced the highest (2.25 t ha -1 ) seed yield. The combined use of 20 kg N/ha and 8 kg Zn ha -1 along with recommended doses of other fertilizer would be beneficial to increase the seed yield of chickpea variety BARI Chhola-2 (Baral).
