ABSTRACT
Field studies were carried out during third year of the fixed site in kharif and rabi seasons of 2015-16 at MARS, Dharwad to evaluate different conservation tillage systems and nutrient management practices on crop yields in three sequence cropping systems. No tillage with BBF and FB, crop residues retained on the surface and application of inorganic fertilizers along with FYM (CT1NM2 and CT3NM2) were recorded significantly higher yields in all the cropping systems in both the seasons over other treatments and conventional tillage systems. With respect to system productivity CT1 and CT3 recorded significantly higher maize equivalent yield (7914 and 7786 kg ha-1) as compared to other tillage practices. With respect to cropping systems groundnut followed by sorghum has recorded higher productivity over rest (9575 kg ha-1). Between the nutrient management application of RDF along with FYM found significantly superior over RDF alone (7629 and 7266 kg ha-1 respectively). CT3 found significantly superior with respect to net returns over rest of the treatments (60654 ha-1). Among the interactions CT1CS1NM1 recorded significantly higher net returns ( 95777 ha-1) and found superior over other interactions.
