potential to increase SOC sequestration in the rice-based cropping system. The equilibrium SOC
concentration is higher with an integrated application of N with FYM. Climate change decreases
the rate of SOC sequestration in all the studied agroecosystems, with higher decreases reported
under RCP 8.5, followed by RCP 6.0, RCP 4.5, and RCP 2.6.

Cotton is one of the most important cash crops which plays a key role in the economy of farmers.
The nutrient removal by crops is generally more than that supplied through chemical fertilizer
and this negative balance over the year led to low fertility status of soil, which resulted in a
decline in the crop yield. Adequate and timely application of organic and inorganic fertilizers not
only increases crop yield but also improves the physical, chemical, and biological properties of
soil. When integrated nutrient management through chemical fertilizers and different organic
sources is applied on a long-term basis, they show a beneficial impact on soil quality (Swarup
2010).The application of green manures to soil is considered a good management practice in any
agricultural production system because it stimulates soil microbial growth and their activities,
besides mineralization of organically bound plant nutrients, and therefore increases soil fertility
and quality (Doran et al., 1988). Therefore, the present study was carried out to study the effect
of conjoint use of organic and inorganic sources on soil fertility, chemical properties, and
productivity of cotton under cotton-based intercropping systems in Vertisols in the Vidarbha
region of Maharashtra, India.
Methodology
The present investigation was conducted at Research Farm, Department of Soil Science and
Agricultural Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year
2017-18 to 2020-21 on Vertisols. The study has focused on the conjoint effect of nutrient
management and a cotton-based intercropping system. The field experiment was comprised of the
main plot (nutrient management) and subplot (cotton-based intercropping systems) with three
replications. There are two treatments of nutrient management (INM and only organics) and five
