Yield of green super rice (GSR) lines under legowo and squared planting system

Green Super Rice (GSR) is rice genotypes designed to have high yield which is stable under low input Conditions. Legowo was reported to give higher yield compared to The square planting system. This research aimed to study The yield of 10 GSR lines along with four checks. i.e. Situ Bagendit, Ciherang, Inpari 8, and Inpari 13 under legowo 2: 1 (20 cm x 10 cm x 40 cm) and square (20 cm x 20 cm) planting system. The experiment was conducted in ICRR experimental station in Sukamandi during DS 2012 following split-plot design of two replications with The spacing system as the main plot and genotype as a subplot. Transplanting was conducted at 21 days after sowing into 3 m x 7 m plots of 1 - 3 seedlings/hill. The results showed that the interaction between genotypes and spacing systems was identified only for plant height. There were differences among genotypes on plant height, tiller number, unfilled grain/panicle, 1000 grain weight and yield. The spacing systems affected The tiller number and yield. Huanghuazhan (8.81 t/ha) had highest yield, higher than The best check Ciherang (7.81 t/ha). FFZ1, IR 83140-B-11-B, IR 83142-B-19-B, WTR 1 dan Zhongzu 14 considered to be adapted for legowo planting system. Keywords: Green Super Rice, Planting System, legowo
