Effect of Various High Puddles on the Growth of Aerenchyma and the Growth of Rice Plants (Oryza sativa L) in Pot

Abstract

Long-term goal of the research is to improve the productivity of paddy crop which is a modification of the SRI (the System of Rice Intensification) of environmentally sound, reducing water use effectively and efficiently (saving water). In that case, the cultivation of which will be applied in the future is that paddy cultivation requires no much water (less than SRI and PTT) and the land from the beginning until the harvest is not stagnant but still moist (because the aeration of soil is pretty good) and oxidation of the soil layer becomes thicker as needed for rice productivity. While the specific objectives of this research is to study the growth of Aerenchyma tissue as a pathway where the release of methane gas from the soil and the growth of rice in the rice fields. This study wanted to obtain an optimal soil conditions, using Complete Randomized Design through vary of water depth level treatment (levels of soil water in pot) in the pot varies. The obtained results of this research are the latest results as different from previous research results. Finally the research obtained some conclusions; 1.) The growth of Aerenchyma in roots of rice plant Batang Piaman was not affected by high of inundation and soil water content in the potting media, 2.) The best rate of assimilation is treatment D (inundation of 10cm from the ground); 3.) the highest total number of seedlings obtained in treatment D (high pool of 10cm from the ground) which is 64.26 rods, far more than the other treatments and descriptions of varieties of rice Batang Piaman itself ie from 14 to 19.4; 4.) Base on the number of seedling growth parameters, high-tech farming with an inundation of 10cm below the soil surface (treatment D) can produce 180% better than conventional cultivation techniques (treatment A) 5.) We applied the latest rice cultivation technology with a high inundation of ±10 cm below the ground surface will provide an optima l effect on the growth of rice plants in field.
