APPLICATION OF VARIOUS TYPES OF MULCH ON THE GROWTH AND PRODUCTION OF SOYBEAN (GLYCINE MAX L. MERRIL) IN SUSTAINABLE AGRICULTURE SYSTEM

Abstract

Utilization of natural resources to increase agricultural production is part of the concept of sustainable agriculture, the natural resources in question are rice husks, sawdust and other materials derived from nature. This study aims to determine the best type of mulch in increasing the growth and yield of soybean plants. This study used a one-factor Randomized Block Design (RBD) consisting of 5 treatment levels, namely: without mulch (F0), rice husk mulch (F1), wood sawdust mulch (F2), black plastic mulch (F3) and mulch silver plastic (F4). Each treatment was repeated 3 times so that there were 15 study plots. The results of the study by giving rice husk mulch gave better results than all types of mulch used. In observing the height of the soybean plants, at the ages of 20, 30 and 40 DAP, they were 18.39 cm, 20.49 cm and 22.80 cm respectively. The average number of leaves at the ages of 20 and 30 HST were 14 each. 33 pods and 29.27 pods, the average number of pods per plant was 177.67 pods, and the average seed weight per plant was 120.72 g. Utilization of rice husk mulch can increase the growth and yield of soybean plants.
