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.

Abstract

Jarak pagar (Jatropha curcas L.) is one of biodiesel resources with high oil content of 35 to 45%. It can grow up in vegetative and generative way. Growth of this plant could be enhanced by giving natural Plant Growth Regulator (PGR) such as cow’s urine which is easy to take, easy to apply, and cheaper than other materials. PGR will be useful for plant if given in low concentration, but in high concentration it will damage the plant. This research aimed to know influence of interaction of storage period and urine concentration to the plant’s growth. It used randomized factorial block experiment with two factors and three replications. The two factors were: (1) storage time of urine (8, 12, and 16 days), and (2) cow’s urine concentration of 25, 50, 75, and 100%.Key Word : cow's urine, jarak pagar, Jatropa cuircas
