Abstract:
A laboratory experiment was conducted on shelf-life of jeevamrutha at Zonal Agricultural and Horticultural Research Station (ZAHRS), Brahmavar, Udupi. In this study cow dung and cow urine of three different desi cow breeds viz., malnad gidda, gir and sahiwal were collected aseptically and separately to prepare Jeevamrutha. After preparation of jeevamrutha samples were collected daily from 1^st day to 15^th days and enumerated the general and beneficial microorganisms viz., bacteria, fungi, actinomycetes, phosphate solubilizing microorganisms (PSM), nitrogen fixers, Pseudomonas, potassium solubilizing microorganisms (KSM), Zinc solubilizing microorganisms (ZnSM) and Trichoderma with their respective media. Among the three desi cow breeds the jeevamrutha prepared from, malnad gidda breed of cow contained the maximum microbial population. In general, the highest microbial population was noticed between 7 to 9 days after preparation (DAP) of jeevamrutha in all the desi breeds. Hence, it’s considered as a best time for the application of jeevamrutha to soil to improve the soil microorganisms.
