POLA PENANGANAN KUANTITAS AIR DENGAN SYSTEM OF RICE INTENSIFICATION UNTUK MENINGKATKAN PERTUMBUHAN PADI (Oryza sativa )

Abstract

System of rice intensification (SRI) is one method to overcome water shortages and can increase rice growth. Rice plants in general really need water for growth, one of which is using the SRI method. The purpose of this study was to determine the effect of water discharge on rice growth in Haekto Village, North Central Timor Regency. The method used in this study is the observation method, in the research area 4  experimental plots measuring 3x4m were carried out. The data collection technique used in this research is descriptive quantitative. The results showed that 2cm high standing water in SRI plots couid increase rice growth at 21 days after planting with a plant height of 39.81cm while the number of leaves was 46,2cm and the number of tillers was 26,58 stems with a water requirement of  345,12 /dt. While in ordinary plots 5cm water puddle height can increase rice growth and has a significant effect treatment with the water requirement of 391,56/dt. This shows that the water demand in the SRI plots is lower than the regular plots.
