Influence of Fermented Rice-Water on Mung Bean

Abstract

INTRODUCTION

Throughout the world, farmers were ensuring that they harvest enough supply of crops that will match local demands. For this, fertilizers were applied. However, synthetic fertilizers pose as deleterious threat not only to human health but also on soil ecology, which interferes the interaction of plants and microorganisms, causing decreased plant growth; for these, a safe, cheap and readily available material was sought to become a potential bio fertilizer. Since rice water acquires the said qualities, it was investigated. Its influences on plants were evaluated using mung bean (Vigna radiata) as a subject for being commonly used as crop.

METHODS

The Randomized Complete Block Design (RCBD) was utilized with two (2) bocks"”W-block and R-block"”with five trials in which, W-block was the control block of mung beans irrigated with water while R-block was the experimental block irrigated with rice water that is openly fermented from the day when the mung beans were triggered to germinate. The irrigation of the two blocks started on day 5 up to day 30, relative to the start of mung bean germination. On day 30, all the mung beans were evaluated in terms of final height, stem count and leaf count. Hence, in the fourth parameter; height increase rate was investigated by determining the heights of plants on days 5, 10, 15, 20, 25 and 30.

RESULTS

The data gathered from the two blocks were comparatively analyzed. Based on the results, the mung beans irrigated with fermented rice water had an average leaf count of 8.4 that is 100% greater than the W-block leaf count of 4.2. In terms of stem count, W-block had a mean of 1.8 while R-block had 3.4. The comparison showed that the R-block was superior over W-block, with 89% higher than the latter. However, on final height and height increase rate of mung bean, W-block had means of 25.78 cm and 1.55 cm every five days, while R-block had 31.46 cm and 2.72 cm respectively. Thus, R-block was once again superior over W-block by a magnitude of 22%, in terms of final height; whereas, on height increase rate, it was greater by 75%.

DISCUSSIONS

The superiority of the mung beans irrigated with fermented rice water over the block irrigated with water is evident. When statistical analysis was applied, generally, there is a significant difference between the two blocks. These results demonstrate the positive influences of fermented rice water on mung beans. Hence, fermented rice water can be defined as an effective bio-fertilizer.
