Growth and Yield of Urdbean Influenced by Vermicompost and Vermiwash

Abstract

The field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) to evaluate the Growth and yield of urdbean [Vigna mungo (L.) Hepper] influenced by vermicompost and vermiwash. The field experiment was carried out during the Kharif season, 2020 on loamy sand soil. The experiment comprising 20 treatment combinations with different doses of vermicompost (control, vermicompost 1.5 t/ha, vermicompost 3.0 t/ha, vermicompost 4.5 t/ha and vermicompost 6.0 t/ha,) and foliar spray of vermiwash (control, vermiwash 5%, vermiwash 10% and vermiwash 15%) was carried out in a 3 times replicated factorial randomised block design. The research explored the effect of various doses of vermicompost and vermiwash on different growth parameters and yield of urdbean on various stages. Results revealed that application of vermicompost 4.5 t/ha significantly enhanced the growth attributes of urdbean viz., plant height, number of branches/plant, dry matter accumulation at 50 DAS and at harvest, CGR (Crop Growth Rate), LAI (Leaf Area Index), chlorophyll content, number of total and effective root nodules, fresh and dry weight of nodules. It also recorded significantly higher seed, stover and biological yields (940, 1920 and 2860 kg/ha) over lower levels. However, it was seen to be at par with vermicompost 6.0 t/ha. Results further showed that application of vermiwash 15% foliar spray at the time of flower initiation stage also resulted in significant increase in the above all mentioned growth parameters as well as recorded highest yield.
