Abstract

Zinc (Zn) and boron (B) deficiency are widespread nutritional disorders in crop plants, including mustard. However, Zn-B interaction on the performance of mustard crops is not well documented. A field experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh, during November 2021 to February 2022 to evaluate the effect of rate and method of Zn and B application on the yield performance of mustard (BARI Sarisha-18). The experiment comprised nine doses of Zn & B as a basal and foliar application viz., recommended Zn (2 kg ha-1) and B (2 kg ha-1) as basal, 75% Zn and B as basal + 25% Zn and B foliar spray at pre- flowering stage, 50% Zn and B as basal + 50% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn and B foliar spray, 100% Zn and B as basal + 25% Zn foliar spray, 100% Zn and B as basal + 25% B foliar spray, 100% Zn as basal (without B), 100% B as basal (without Zn), control (no Zn and B). The experiment was laid out in a Randomized Complete Block Design with three replications. The result revealed that yield was influenced significantly by the rate and method of Zn and B application. The highest plant height (140.57 cm), the maximum number of branches plant-1 (5.84), maximum number of effective pods plant-1 (87.57), maximum number of seeds pod-1(31.53), the highest seed yield (1.85 t ha-1) and the highest stover yield (4.47 t ha-1) were obtained from 100% Zn and B as basal + 25% Zn as foliar. The lowest number of seeds pod -1 (27.20), 1000-seed weight (3.35 g), seed yield (1.33 t ha-1) and stover yield (3.35 t ha-1) were obtained from the control treatment. The result showed that the seed yield of mustard increased with increasing levels of both Zn and B as basal 100% with only Zn 25% as foliar, respectively. Therefore, 100% zinc combined with 100% B as basal and 25% Zn foliar application may be recommended for higher seed yield of mustard (cv. BARI Sarisha-18).

锌硼用量和施硼方式对芥菜产量的影响

锌(Zn)和硼(B)缺乏症是包括芥菜在内的农作物普遍存在的营养失调症。然而，锌-硼互作对芥菜作物生产性能的影响还没有很好的文献记载。2021年11月至2022年2月，在孟加拉国农业大学Mymensingh农学田间实验室进行了一项田间试验，以评估锌和B的施用量和方法对芥菜(BARI Sarisha-18)产量性能的影响。实验由九个剂量的锌& B作为基底和叶面应用程序即。,推荐锌(2公斤是)和B(2公斤农业作为基底,75%的锌和基底+ 25%锌和B叶面喷雾在开花前的阶段,50%的锌和基底+ 50%锌和B叶面喷雾,100%锌和B基底+ 25%锌和B叶面喷雾,100%锌和B基底+ 25%锌叶面喷雾、100%锌和B基底+ 25% B叶面喷雾,100%锌基底(没有B), 100% B作为基底(没有锌),对照(不含Zn和B)。试验采用随机完全区组设计，3个重复。结果表明，锌和硼的施用速率和方式对产量有显著影响。100% Zn + 25% Zn处理的最高株高(140.57 cm)、最大分枝数(5.84)、最大有效荚果数(87.57)、最大种子数(31.53)、最高种子产量(1.85 t ha-1)和最高秸秆产量(4.47 t ha-1)。对照处理的种子荚数(27.20)、千粒重(3.35 g)、种子产量(1.33 t ha-1)和秸秆产量(3.35 t ha-1)最低。结果表明，随着锌和硼含量的增加，油菜籽粒产量均有显著提高。因此，建议采用100%锌+ 100% B的基施和25%锌的叶面施可以提高芥菜的籽粒产量(cv。巴里Sarisha-18)。
