PENGARUH PENGGUNAAN JARAK TANAM TERHADAP PERTUMBUHAN DAN PRODUKSI PADI SAWAH (ORYTXI SATIVA L.) VARIETAS IR 42 DENGAN METODE SRI (SYSTEM OFRICE INTENSIFICATION)

Abstract

Kampar District is one ofriceproduction centres in Riau, so it is important to develop SRI (System of RiceIntensiOcation) method. To apply this method, we should know therightdbunce for thericeto be plantedbecause the farmers stfll use pbinting disUnce of25 x 25 on. The research used Randomized Block design,with four treatments and three repltcattoas. The treatment is the planting distance as ibUow: 25 1 25 cm (SI),30 X 30 cm (S2), 35135 cm (S3) and 40 x 40 cm (S4). The result of analysis was tested by Duncan's NewMultiple Range Test (DNMRT) at 5% level. The research result showed that by SRI method, thericepiantgrow and produce very well with planting distance of 40 K 40 cm and the production of dry unpolished grainis 6^8 kg per plot.
