Effects of Vermicompost and Mineral Water on the Growth Parameters of the KDML 105 Rice Cultivar

抄録

The purpose of this research aimed to study the effects of vermicompost and mineral water from a wellspring in Ban Haubueng Community Forest, Nampong District, Khon Kaen Province, Thailand on the growth parameters of rice cultivar KDML 105. The rice growth experiments were conducted in a completely randomized design, with four irrigation treatments: irrigation water (T0), irrigation water with vermicompost (T1), mineral water (T2), and mineral water with vermicompost (T3) under greenhouse conditions. The results found that the application of the vermicompost with mineral water gave the highest rice growth parameters; such as plant height, panicles, grains per panicle, and number of tillers per hill, with a significant difference of p ≤ 0.05. The highest plant height (139.63 cm.) was found in the T1 treatment, and the highest number of tillers per hill and grain weight were found in the T3 treatment at 7.00 and 175.28 grams per plot, respectively; as vermicompost is a rich source of readily available nutrients and contains growth hormones. Although the application of mineral water produced lower plant heights than that of the irrigation water, the tillered rice demonstrated an increased number of tillers per hill and grains per panicle. The results of this experiment revealed that the addition of vermicompost and mineral water had significant positive effects on plant growth parameters of rice. It can conclude that the utilization of mineral water from the wellspring community forest with vermicompost could help farmers to increase rice production.
