Cotton is one of the important cash crops and plays a vital role in the economy of the farmer as
well as the country. Vidarbha is a major cotton and cotton-based cropping system growing
region in central India where it is grown predominantly as a rainfed crop on medium to deep
Vertisols. The low content of soil organic carbon in Vertisols in addition to low availability of N,
P, and Zn resulted in unsustainable productivity of cotton and cotton–based cropping systems
(Blaise et al. 2005) thereby deteriorating soil health. In the present conditions, the continuously
