Soil organic carbon (SOC) is a strong determinant of soil quality and crop productivity,
especially in the arid and semiarid environments of the tropics. Drought stress, high
temperatures reaching up to 45 C for 8–10 weeks in a year, coupled with low biomass
productivity are common features of dry agroecosystems. India, with only 2.5% of the
world’s geographical area, is a home to 17% of the global population. Population
increased from 361 million in 1951 to 1140 million in 2011, more than threefold increase
over 50 years. Productivity levels of rainfed dryland crops are far below those of global
average. Thus, increasing productivity of rainfed cropping systems is an urgent task to
meet the food demand of an ever-increasing population because 57% of the total arable
land area of 141 Mha is under rainfed farming.
Yields of important rainfed production systems in long-term manurial experiments
under different climate and soil types show declining trends even with adoption
of some recommended management practices (RMPs). Some RMPs include diverse
crop rotations with legumes, and integrated nutrient management (INM) involving
addition of farmyard manure (FYM), use of groundnut shells (GNS) and other
crop residues (CRs), green leaf manuring (GLM), etc. These RMPs have been tested in
seven long-term experiments of 13–27 years duration established in diverse soils and
agroecoregions.
