The adaptive trials were conducted during 2002–04 in four villages of two districts in Meghalaya to find out the productivity, profitability and economic feasibility of maize – mustard cropping system. Significantly higher grain yield (36.18 q ha−1), increase of grain yield over farmers’ practices (74.94%), productivity (50.18 q ha−1 MEY), net return (Rs. 10178 ha−1 year−1) and benefit: cost ratio (2.03) were recorded maximum with IPNS technology of FYM @ 5 t ha−1 + recommended dose of fertilizers in maize (80:60:40 kg NPK ha−1) on farmers field at all the locations. The highest production potential (40.91 q ha−1) was recorded at Lumkremmonbhut followed by Mawlasnai (38.65 q ha−1). However, the highest harvest index (0.126) was recorded at Mawlasnai and land utilization efficiency (71.78%) at Mawbri.
