Abstract
A field experiment was conducted to evaluate the effect of vermicompost and vermiwash on the nutrient uptake and economics of black gram (Vigna mungo L.) at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during Kharif, 2020. The treatments comprised different doses of vermicompost and vermiwash totaling 20 treatments. It was replicated 3 times in FRBD (factorial randomised block design). Results revealed that application of vermicompost 6.0 t/ha significantly enhanced the nutrient content (nitrogen, phosphorus and potassium) in seed and straw, protein content in seed, the nutrient uptake by seed, straw and total uptake. It also recorded significantly higher gross returns over lower levels. However, higher net returns were observed under vermicompost 4.5 t/ha application. Results further showed that application of vermiwash 15 % foliar spray at the time of flower initiation stage also resulted in significant increase in nutrient content in seed and straw, protein content in seed, nutrient uptake by seed and straw with highest total uptake, gross and net returns of black gram.
Keywords: Gross returns, foliar spray, nutrient uptake, protein content, black gram
