Integrated nutrient management for summer irrigated cotton - greengram cropping system

摘要

Extensive work has been done on the fertilizer management for cotton under summer irrigated conditions. However, work on INM for system as a whole is lacking. Besides, the increasing cost of chemical fertilizers coupled with its adverse effect on soil health has necessitated the researchers to evolve INM with reduced use of inorganic fertilizers, particularly N. The response of cotton to Azospirillum and greengram to Rhizobium (Shukla and Dixit, 1996) has been well documented. So far attempts were made to study the effect of combined use of chemical fertilizers and biofertilizer on crops individually. Hence, a need was felt to study the combined application of inorganic and biofertilizers in cotton based cropping system as a whole.
