The varietal and spacing study was laid out in randomized complete block design with two factors replicated thrice. There are three varieties (Jaya, Rasi and MTU -1010) and six planting geometry cm (30x10,30x15, 30x20, 30x30 cm, 40 x 10 and 40x15). The results of the study reveal that, significantly higher grain yield (55.95 q ha-1) was obtained with Rasi, which was significantly superior over MTU-1010 (53.76 q ha-1) and Jaya (50.58 q ha-1) varieties. Among the different planting geometry, (30 cm x30 cm) showed significantly higher grain yield (57.02 q ha-1) compared to 30 cm x 15 cm (52.94 q ha-1) and 30 cm x10 cm (50.31q ha-1). Experiment on intercropping in aerobic rice was laid out in a randomized complete block design with three replication having two factors. viz. two row patterns (normal row 45 cm x 20 cm, and paired row 30/60 cm x 20 cm) and seven intercrops (rice + bhendi, rice+cluster bean, rice + french bean, rice +ragi, rice +radish, rice + soybean, and rice+sunhemp) consisted of 14 treatments. Significantly higher grain yield (23.7 q ha-1) was obtained in paired row intercrops than in normal row (19.7 q ha-1) intercropping. Significantly higher grain yield (27.7 q ha-1) was recorded with rice + bhendi intercropping system and rice+ cluster bean (26 q ha-1) intercropping systems. Significantly, lower grain yield (6.8 q ha-1) was obtained in rice + ragi intercropping system. In conclusion, Rasi variety grown with 30cmx30cm under aerobic condition resulted better yield. Rice + bhendi intercropping system provided high Rice yield as well as rice equivalent yield (8167 kg ha-1).ennullThesis
