Effect of different Jeevamrut based liquid organic formulations on biochemical properties of soil and on plant growth of blackgram [Vigna mungo (L.) Hepper] under pot culture conditions

Abstract

A pot culture experiment was conducted at organic farming unit, Rajasthan College of Agriculture, MPUAT, Udaipur, to study the effect of different jeevamrut based liquid organic formulations on biochemical properties of soil and on plant growth of blackgram during kharif 2019. The various types of liquid organic formulations were prepared from plant and animal origin wastes and are effective in the promotion of growth and fruiting in blackgram. Jeevamruth promotes immense biological activity in soil and enhance nutrient availability to crop. Similarly, beneficial effects of silicon, vermiwash and leaf extracts (of lemon grass and Aleo vera) have been reported to protect the crop from soil borne and seed borne pathogens and also improves seed germination. In the present study, significant highest plant growth and root length was recorded with the application of jeevamrut + lemon leaf extract (2.5%) + Aloe vera leaf extract (2.5%) + silica (1%) + vermiwash (5%) and it was found to be significantly superior over other treatments. The N, P, and K concentration of plants and microbial population and dehydrogenase activity of soil was significantly highest in the treatment given jeevamrut + lemon leaf extract (2.5%) + Aloe vera leaf extract (2.5%) + silica (1%) + vermiwash (5%).
