Effects of Soil Tillage on the Agronomic Performance of Maize-Soybean Intercropping in Dry Land North Lombok, Indonesia By IJISRT

Abstract

If land processing techniques on dry land are not carried out correctly, it can cause soil erosion and poorer soil fertility. Therefore, one way that can be done to prevent the soil from becoming sour is through proper soil processing accompanied by the addition of bio- ameliorants to the soil. This research aims to determine the effect of soil tillage on the agronomic performance of corn and soybean intercropping on dry land in North Lombok, Indonesia. The research was conducted from May to July 2023 in Pemenang Barat Village, Pemenang District, and North Lombok Regency. The study used an experimental method in the field using a randomized block design by testing five tillage techniques, i.e., Oo: without tillage; O1: without tillage, only sprayed with pre-growth herbicides before planting; O2: minimum tillage is only hoeing; O3: simple tillage and leveling; and O4: intensive tillage by hoeing, loosening, and leveling. The results showed that treatment-intensive and complete processing can increase the growth performance and biomass yield of maize and soybean intercropping. Treatment-intensive and complete processing can improve the performance of intercropping maize and soybeans in the dry land of North Lombok. To improve the agronomic performance of maize-soybean intercropping in the dry land of North Lombok, the best results are obtained using intensive and complete processing accompanied by the addition of bio-ameliorant at a dose of 15 tons per ha.
