Influenced of Panchakavya on soil fertility status and yield of ashwagandha (Withania somnifera)

The field experiments were conducted to study the available N,P,K and S in soil with the effect of Panchagavya made from cow (PK-C) and buffalo (PK-B) products sprayed to plants and applied to soil with different concentrations (3 and 5 per cent to plant and 9 and 15 per cent to soil) at different intervals (3 sprays -30, 60 and 90 DAS; 4 sprays -20, 40, 60 and 80 DAS) during rabi 2007–08 and kharif 2008. The available nutrients viz., N, P, K, and S was highest with PK-C @ 15% to soil (T₁₀) but it was at par with soil application of PK-B @ 15% to soil and PK-C@ 5% -4 sprays.
