organic carbon, and CaCO3 were found to be non-significant. Whereas numerically higher
values for pH were observed in T 10 and higher values of EC and organic carbon were
observed in T 3. The differences in micronutrients were found to be significant. Among
various treatments, T3 showed a higher concentration of all micronutrients. Among various
organic sources of nutrients the treatment i.e. T 3: 100 % RDN through 33% FYM + 33%
VC + 33% NC available macronutrient in soil N, P, and K . (218, 21.52 and 516 kg/ha). The
treatments had RWUE of more than one except the control plots and it was found highest in
treatment T 13 followed by T 2. The positive effects of organic manure application on the
performance of soybean and other crops in black soils are well documented by Aher et al.
2015. The differences for pH, EC, organic carbon, and CaCO 3 were found to be nonsignificant.
Whereas numerically higher values for pH were observed in T10 and higher
values of EC and organic carbon were observed in T 3.
Conclusion
Among various organic sources of nutrient treatments, application of 100 % RDN through
33% FYM + 33% VC + 33% NC (T3) recorded the highest available nutrients in soil N, P,
and K (218, 21.52 and 516 kg/ha). Potassium was found in RDF + FYM 5 t /ha (T 13) followed
by 33% FYM + 33% VC + 33% NC (T3) as a organic source of nutrients.
