International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad A field experiment was conducted during the rainy (kharif) season in 2019, 2020 and 2021 under rainfed conditions in a randomised block design with 4 replications. There were 6 treatments with different strip widths of maize and blackgram, which included maize strip 3 m wide and black gram 2.4 m(T1), maizestrip6 m wide and black gram 2.4 m (T2), maizestrip3 m wide and black gram 4.8 m (T3) , maize strip 6 m wide and black gram 4.8 m (T 4), sole maize (T 5) and sole black gram (T 6).The maize variety PMH-1 was sown at a spacing of 60 cm x 20 cm and blackgram variety mash-114 was sown at 30 cm x 10 cm spacing respectively using 20 kg seed per hectare for each crop. The crops were harvested from the last week of September to the first week of October during three years of experimentation. Results Strip-intercropping of maize and black gram resulted in higher yield than sole crops of maize and black gram. The highest maize equivalent yield (MEY) was recorded in maize strip 6 m wide and black gram 2.4 m (3439 kgha -1 ) which was significantly higher overthe sole crop of maize by 11.3% and black gram by 14.8% but at par with maize and black gram stripintercropping systems. The highest LER (1.14), rain water use efficiency (4.98kg ha -1 mm -1 ) and net returns (Rs 40393 ha -1 ) was recorded with maize and black gram strip-intercropping in 6 m and 2.4 m, respectively. However, the BC ratio (2.32) was highest in maize strip 3 m and black gram strip width 4.8 m followed by 6 m and 2.4 m strip width (2.27).

International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad Conclusion Results of this three-year study indicated that maize and blackgram strip-intercropping system is more effective than a monoculture system in resource utilization. The cultivation of maize in6 m wide strip and blackgram in 2.4 m wide or maize in3 m wide strip and blackgram in 2.4 m wide strip is the most efficient strip-intercropping system to get higher yield and economics than other combinations of rows.
