Abstract
This study aims to evaluate the response of growth and production of three varieties of irrigated rice (Oryza sativa L.) to paclobutrazol application with jajarlegowo 4: 1planting system. This research was carried out in the rice field area of Serbajadi 1 Village, Sunggal District, Deli Serdang Regency, Medan. This study uses a separate plot design (RPT) with 2 treatment factors. The first factor is paclobutrazol as the main plot consisting of 4 levels, namely P0 = 0 ppm (without the application of paclobutrazol), P1 = 50 ppm, P2 = 100 ppm, P3 = 150 ppm. The second factor is varieties as subplots consisting of 3 levels, namely, V1 = Inpari 32, V2 = Inpari 4, V3 = Mekongga. The results showed that the best growth and production of rice plants were in the treatment of paclobutrazol concentration of 150 ppm in the Inpari 4 variety, with a plant height of 59.93 cm, number of tillers 33.40 tillers, panicle number of 18.60 panicles, grain weight containing 26.98 g and grain production 1.82 g per plot.
