Abstract

The provision of sufficient and sustainable food continues to increase as the population increases. A strategic effort to increase land productivity is the intercropping planting system. However, to what extent the profitability and land efficiency of the intercropping system, especially maize and soybeans in dryland, has not been thoroughly studied. This study aims to determine the profitability and efficiency of land use in various population combinations of soybean and maize in the intercropping systems in dryland. The experiment was arranged in a randomized block design involving five treatments of maize and soybean population, i.e., 1. maize monoculture (planting space: 40x35 cm); 2. 1 row of maize: 6 rows of soybeans (25%: 75%); 3. 2 rows of maize:4 soybean rows (50%:50%); 4. 3 rows of maize:2 rows of soybean (75%:25%) and 5. soybean monoculture (planting space 30x20 cm). All treatments were repeated 5 times. The experimental results showed land equivalent ratio (LER) of soybean and maize increased with the decrease in soybean population in the same land unit. However, the increase was moderate in the composition of soybean 2 rows of and 3 rows of maize. Thus, the optimum LER was obtained at the composition of 4 rows of soybeans and 2 rows of maize (land occupation of 50%:50%). Farmers income from intercropping soybean+maize was higher than the monoculture of soybean and maize in dryland. The most profitable combination of soybean+maize intercropping was at a composition of 50:50% or 4 rows of soybeans and 2 rows of maize. This is indicated by the optimum profit given by the combination population of soybean and maize intercropping with the B/C ratio of 1.92.
