Abstract

A field study was performed at the Bangladesh Institute of Nuclear Agriculture (BINA) sub-station farm, Rangpur during Rabi season of 2021-22 to determine the effect of varieties and foliar application of boron on the growth and yield of green chili. The treatments were laid out in a Split-plot and replicated three times. Different concentrations of foliar Boron were applied as foliar sprays. The experiment comprised of nine treatments: T1= 0.5 g BL-1H2O at vegetative stage, T2= 1.0 g BL-1H2O at vegetative stage, T3= 0.5 g BL-1H2O at vegetative stage + 1.0 g BL-1H2O at Fruiting stage, T4= 1.0 g BL-1H2O at vegetative stage + 1.0 g BL-1H2O at Fruiting stage, T5= 1.5 g BL-1H2O at vegetative stage & T6= 1.5 g BL-1H2O at vegetative stage + 1.5 g BL-1H2O at Fruiting stage, T7= 2.0 g BL-1H2O at vegetative stage, T8= 2.0 g BL-1H2O at vegetative stage + 2.0 g BL-1H2O at Fruiting stage & T9 = Control and two chili varieties/lines viz. Binamorich-2 & RCL-1. From the present study, it was concluded that the highest fresh chili yield (18.11 tha-1) produced Binamorich-2 compared to RCL-1 which gave 14.52 tha-1. Among the nine treatments of foliar boron, B @ 2.0 g/L H2O at vegetative stage + B @ 2.0 g/L H2O at fruiting stage exhibited the highest fresh chili yield (21.22 tha-1). In respect of the interaction effect of foliar boron and variety, the Binamorich-2 was giving the highest fresh chili yield (25.00 tha-1). However, further research will be needed with different doses of foliar boron for promising production of chili at different locations of Bangladesh.

叶面施肥硼对青辣椒生长和产量的影响

2021-22 年腊月期间，孟加拉国核农业研究所（BINA）在兰普尔（Rangpur）分站农场进行了一项田间研究，以确定品种和叶面喷施硼对青辣椒生长和产量的影响。试验采用分株法，重复三次。叶面喷施不同浓度的硼。试验包括九个处理：T1=无性期 0.5 g BL-1H2O，T2=无性期 1.0 g BL-1H2O，T3=无性期 0.5 g BL-1H2O + 果实期 1.0 g BL-1H2O，T4=无性期 1.0 g BL-1H2O + 果实期 1.0 g BL-1H2O，T5=无性期 1.5 g BL-1H2O & T6= 1.5 g BL-1H2O 在无性期 + 1.5 g BL-1H2O 在果期，T7= 2.0 g BL-1H2O 在无性期，T8= 2.0 g BL-1H2O 在无性期 + 2.0 g BL-1H2O 在果期，T9 = 对照和两个辣椒品种/品系，即 Binamorich-2 和 RCL-1。本研究得出的结论是，Binamorich-2 的鲜辣椒产量最高（18.11 吨-1），而 RCL-1 为 14.52 吨-1。在 9 个叶面喷硼处理中，植株期喷 B @ 2.0 g/L H2O + 果实期喷 B @ 2.0 g/L H2O 的辣椒鲜重产量最高（21.22 tha-1）。在叶面喷施硼与品种的交互效应方面，Binamorich-2 的鲜辣椒产量最高（25.00 tha-1）。不过，还需要进一步研究不同剂量的叶面喷硼，以提高孟加拉国不同地区的辣椒产量。
