Description
Summary:Intercropping is an agricultural method that involves planting more than one type of crop in the same area. The goal of this practice is to maximize the use of nutrients, water, and sunlight to achieve optimal results. This study aims to evaluate the chemical properties of soil as well as the growth of soybeans (Glycine max L. Merill) by using vetiver (Vetiveria zizanioides) as an intercropping system and organic mulch application. The research design used random blocks with five treatments, namely K0 (soybean monoculture); K1 (intercropping of soybeans and vetiver); K2 (intercropping of soybeans and vetiver with organic mulch); K3 (soybeans with organic mulch); and K4 (vetiver monoculture), repeated five times each. The results showed that intercropping soybeans with vetiver added organic mulch did not increase soybean or vetiver growth. The land equivalency value for K1 treatment (intercropping of soybeans and vetiver) was recorded at 1.80, while the K2 treatment (intercropping with the addition of organic mulch) was 1.26. The competition index for K1 is 1.06 and for K2 is 0.80. These results show that intercropping soybeans with vetiver plus organic mulch is more advantageous compared to soybean monocultures.
