Abstract

The lower produce of paddy crop ( Oryza Sativa L.) in Indonesia caused by the conventional system that still rely generally by the farmer in Indonesia. Conventional system used much water, more seed, narrow transplanting space, and late transplanting (3 - 4 week after planting). By using SRI method (The System of Rice Intensification) in paddy yields, can decreasing water usage, less seed, wide transplanting space, and earlier transplanting (1 – 2 week after planting). The main objective of this study was to propose the finest transplanting space and transplanting age in order to improving growth and result of paddy crop by SRI method. The result showed that modifying transplanting space and transplanting age can increase paddy result. There is three difference plant spacing ( 20 cm x 20 cm, 25 cm x 25 cm and 30 cm x 30 cm) and three transplanting age (1, 2 and 3 week after planting). Study used transplanting space 30 cm x 30 cm with earlier transplanting 1dan 2 week after planting gives best result since SRI method give opportunity to tillering grow maximally, lessening forming aerenchyma, and strengthen root, grow on to become health, increasing nutrition and crop metabolism.This condition become synergism to repairing canopy photosynthesis so that assimilates yielded better. The result of this study are wider spacing is better than narrow spacing, and earlier transplanting (1dan 2 week after planting) is better than late transplanting (3 week after planting). Kata Kunci : SRI (The System of Rice Intencification), jarak tanam, umur bibit
