Abstract

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

叶面施用蚯蚓水对茄子生长和品质的影响

本试验于2019-2020年和2020-2021年在孟加拉国贾马尔布尔区域农业研究站(RARS)进行，旨在研究蚯蚓水对茄子生长、产量和品质的影响，并确定蚯蚓水叶面用量以优化茄子产量。5个处理分别为T1=化肥(CF) +蒸馏水叶面喷施(对照)、T2 = CF +叶面喷施10%驱虫水、T3 = CF +叶面喷施20%驱虫水、T4 = CF +叶面喷施30%驱虫水和T5= CF +叶面喷施40%驱虫水。结果表明，蚯蚓水处理茄子植株的生长和产量指标均优于对照植株。结果表明，叶面喷施20%杀虫剂的T3处理茄子平均产量最高(29.99 t ha-1)，对照最低(26.35 t ha-1)。另一方面，营养品质(水分含量、TSS、β -胡萝卜素和营养成分含量)均高于对照处理。研究表明，20%浓度的蚯蚓水可作为有效的叶面喷雾剂用于茄子的生态友好和高产。
