Abstract

An experiment was conducted at the agriculture research field of Noakhali Science and Technology University, Noakhali-3814, Bangladesh during the period 1st November 2021 to 30 January 2022 to observe the effect of different levels of nitrogen (N) fertilizer on growth and yield of mustard. The experiment comprised four levels of nitrogenous (N) fertilizer viz; control (N0) 0 kg ton ha-1, (N1) 90 kg ton ha-1, (N2) 140 kg t ha-¹, (N3) 190 kg t ha-1. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Application of different levels of nitrogen significantly influenced the Plant height (cm), branches plant-1 (no.), effective siliqua plant-1 (no.), seeds siliqua (no.), 1000-seed weight (g), grain yield (t ha-1), stover yield (t ha-¹), biological yield (t ha-1), harvest index (%) content of mustard. Application of 190 kg ha-1 nitrogen gave the maximum plant height (77.83 cm), Branches plant-1 (5.80), Effective siliqua plant-1 (23.60), Siliqua length (6,17 cm), Seeds siliqua (33.87), 1000-seed weight (3.57 g), grain yield (1.53 t ha-1), Stover yield (3.90 t ha-1), Biological yield (5.43 t ha-1) and the lowest yield was found from control (N0) 0 kg ton ha-1. Consequently, ‘BARI SARISHA-14’ may be suggested to grow for higher yield with N3 treatment. Res. Agric. Livest. Fish. Vol. 10, No. 2, August 2023: 99-107

不同氮肥(尿素)用量对芥菜(Brassica sp.)产量的影响

本试验于2021年11月1日至2022年1月30日在孟加拉国Noakhali-3814 Noakhali科技大学农业研究基地进行，旨在观察不同氮肥水平对芥菜生长和产量的影响。试验包括四个水平的氮肥，即;对照(N0) 0公斤吨公顷-1，(N1) 90公斤吨公顷-1，(N2) 140公斤吨公顷-1，(N3) 190公斤吨公顷-1。试验采用随机完全区组设计(RCBD)， 3个重复。施氮量对芥菜株高(cm)、分枝1号(no.)、有效硅1号(no.)、籽粒硅(no.)、千粒重(g)、籽粒产量(t ha-1)、秸秆产量(t ha-1)、生物产量(t ha-1)、收获指数(%)含量均有显著影响。施氮190 kg hm -1的最高株高(77.83 cm)、分枝1株(5.80 cm)、有效硅1株(23.60 cm)、硅长(6.17 cm)、种子硅(33.87 cm)、千粒重(3.57 g)、籽粒产量(1.53 t hm -1)、秸秆产量(3.90 t hm -1)、生物产量(5.43 t hm -1)，对照(N0)最低产量为0 kg t hm -1。因此，‘BARI SARISHA-14’可能建议在N3处理下获得更高的产量。阿格利司》。力所能及的。鱼。第10卷第2期，2023年8月:99-107
