The Effect of The Concentration of Coconut Water and Rice Water and Seed Soaking Time on The Germination of Mung Beans (Vigna radiata L.)

Abstract

Coconut water is a natural complex compound that is often used as a natural growth regulator. The use of coconut water as organic material is a way to replace the use of synthetic materials in plants. In addition, the benefits of coconut water are also commensurate with synthetic ingredients containing cytokines. So far, rice washing water is considered waste and just thrown away. but actually the washing water still contains carbohydrates, protein and B vitamins which are essential for plant growth. Efforts should be made to use waste into something useful, namely a hormone that is very important in plant growth. The purpose of this study was to determine the effect of coconut water concentration and rice washing water waste and the length of soaking time on the germination of mung bean seeds. Parameters observed were plumule height, number of radicles and radicle length. The treatments given to mung bean seeds were 100 ml of plain water, 10 ml coconut water + 90 ml rice washing water, 20 ml coconut water + 80 ml rice washing water, 50 ml coconut water + 50 ml rice washing water, 90 ml coconut water + 10 ml rice washing water and 80 ml coconut water + 20 ml rice washing water with a soaking time of 2 hours, 4 hours and 6 hours with 3 repetitions. Based on the results of the study, coconut water and rice washing water had an effect on plumule height where the highest plumula was found in the combination (20 ml coconut water + 80 ml rice washing water with 2 hours of immersion). The highest radicle length was found in the combination (10 ml coconut water + 90 ml rice washing water with 6 hours immersion). The highest number of radicles was found in the combination (50 ml coconut water + 50 ml rice washing water with 6 hours immersion).
