TAILIEUCHUNG - Effect of varieties and planting geometry on the yield performance of rice (Oryza sativa L.) under aerobic system of cultivation

A field experiment was conducted during Kharif season of 2004 and 2005 at UAS, Hebbal Bengaluru, on the Performance of Varieties and Planting Geometry in Aerobic Rice Cultivation. The experiment was laid out in Factorial randomized complete block design (RCBD) with three replications. Two factors viz. – variety (3) and spacing (6).Variety consists of Jaya (V1), Rasi (V2) and MTU -1010 (V3), while planting geometry consists of six spacing Viz., 30 cm x 10 cm (S1), 30 cm x 15 cm (S2), 30 cm x 20 cm (S3), 30 cm x 30 cm (S4), 40 cm x 10 cm (S5) and 40 cm x 15 cm (S6). Significantly higher grain yield ( q ha-1 ) was obtained in Rasi, which was significantly superior over MTU-1010 ( q ha-1 ) and Jaya ( q ha-1 ) varieties. Increased yield in Rasi variety is attributed to improved growth and yield parameters. Among different plant geometry, wider and square planting at 30 cm x 30 cm obtained significantly higher grain yield ( q ha-1 ) as compared to closer spacing of 30 cm x 10 cm ( q ha-1 ) and 30 cm x 15 cm ( q ha-1 ) respectively. The result showed that Rasi variety with square planting performed better in aerobic method of cultivation. | Effect of varieties and planting geometry on the yield performance of rice (Oryza sativa L.) under aerobic system of cultivation
