| dc.description.abstract | Field experiments were conducted during the kharif season of 2004 and 2005 at Mian Research Station, Hebbal, University Agricultural Sciences, Bengaluru, to study the Performance of varieties and planting geometry and intercrops in Aerobic rice cultivation. 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). | en_US |
