Abstract


This study aims to determine the effect of layout trimming and urea fertilizer dose, and their interaction on the growth and yield of rice (Oryza sativa L.) varieties Ciherang on salibu system. The study was conducted by using Split Plot Design factorial. First factor is Urea fertilizer application consists of 4 levels. Ie. A0 = 0 kg ha-1 (control), A1 = 125 kg ha-1, A2 = 250 kg ha-1, A3 = 375 kg ha-1. Second factor is trimming layout consists of 3 levels. Ie. B0 = 5 cm from the base, B1 = 10 cm from the base, B2 = 15 cm from the base. Position trimming very significant effect on high Clump aged 4, 8 and 12 weeks after planting (WAP); the number of tillers per Clump aged 4, 8 and 12 WAP; the number of panicles per Clump; the production of dry grain. Urea fertilizer very significant effect on high Clump aged 4, 8 and 12 WAP; the number of tillers per Clump aged 4, 8 and 12 WAP; the number of panicles per Clump; the production of dry grain. Interaction trimming positions and urea fertilizer significant effect on the number of tillers per Clump age 8 WAP.
