PSBK-1. The treatments comprised of two levels of inorganic fertilizers (80% and 60% RDN) and three levels of natural farming formulations viz., jeevamrit (5%, 10% and 15%) and ghanjeevamrit (90%, 100% and 110%), along with positive control (100% RDN; N:P:K (125:76:72 kg ha-1). The experiment was laid out in Randomized Block Design with three replications. Application of. 80% RDN in conjunction with soil drenching of jeevamrit @ 15% at 21 days interval outperformed all other treatments in terms of growth and yield parameters and recorded maximum values for plant height (cm), number of leaves per plant, leaf size (cm2), stalk length (cm), curd size (cm2), gross curd weight (kg), net curd weight (g), marketable curd weight (g) and yield (q ha-1). Application of 80% RDN + Jeevamrit 15% (soil drenching at 21 days interval) recorded highest net returns and 21% increase in yield over control. Experimental results indicated that jeevamrit @ 15% proved effective in increasing soil microbial population and uptake of nutrients by the plantsEnglishThesis
