Effect of Foliar Application of Vermiwash on Growth and Quality of Brinjal

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.

“…The spent wash collected through a drainage pipe provided at the bottom of the vermicompost pit. Vermiwash contains 0.50 per cent nitrogen, 0.39 per cent phosphorus and 0.46 per cent potassium [8]. It is coelomic fluid extraction which contains several enzymes, plant growth stimulating hormones like cytokinins, gibberlines and vitamins along with micro-nutrients and macro-nutrients as nitrogen in the form of mucus, nitrogenous excretory substances [9].…”
