Identification of suitable intercrops performance under aerobic rice (Oryza sativa L) cultivation

Abstract

A Field experiment was conducted during Kharif season of 2004 and 2005 at UAS, Hebbal Bangalore, to investigate the suitable intercrops performance under aerobic rice (Oryza sativa) cultivation. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replication having two factors, factor A (2) row patterns, and factor B: Intercrops (7) and thus experiment was comprised of 14 treatments. Normal row spacing: (45 x 20 cm) and in paired row spacing: (30/60 cm x 20. The Intercrop combinations were as follows, I1 –Rice + Bhendi, I2-Rice + Cluster bean,I3-Rice + French bean, I4-Ric+Ragi, I5-Rice +Radish, I6-Rice + Soybean,I7-Rice + Sunhemph.Significantly higher grain yield (23.7q ha-1) was obtained in paired row intercrops than in normal row (19.7q ha-1) intercropping. Among various inter cropping systems, significantly higher grain yield (27.7 q ha-1) was recorded with Rice + bhendi intercropping system and it was statistically on par with Rice+ cluster bean (26.0 q ha-1) intercropping systems. Significantly lower grain yield (6.8 q ha-1) was obtained in rice+ Ragi intercropping system.
