Abstract: Effect of crop management practices on soil’s carbon pool index, lability index and carbon management index under cotton based intercropping system in Vertisol was investigated during 2015-16 and 2016-17 on Research Farm, Department of Soil Science and Agriculture Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The treatments comprised of control (only cotton), and cotton based intercropping systems viz. cotton + dhaincha (1:1), cotton + sunhemp (1:1), cotton + green gram (1:1), cotton + cow pea (1:1), cotton + black gram (1:1), cotton + pigeon pea (6:2) and cotton + soybean (1:1) which were executed in randomized block design with three replications. The in situ incorporation of dhaincha in cotton + dhaincha intercropping system recorded improvement in physical, chemical and biological properties. Various carbon pools and soil organic carbon stock was registered highest under cotton + dhaincha (1:1) intercropping system which helped to improve carbon lability index, carbon pool index as well as carbon management index.
