Abstract

The experiment was conducted at Kampangsaen Campus, Kasetsart University to investigate the possibility of growing sweet corn (variety Hawaiian sugar supersweet DMR) and soybean (variety S.J.4) in the intercropping. Three intercrop combinations of 75% corn+25% soybean, 50% corn+50% soybean, and 25% corn+75% soybean were used in the experiment in comparison with corn and soybean monocultures. Soybean was harvested for seed while corn was harvested for greed cob.

Abstract

The study of different land preparations and planting methods on the growth and yield of soybean after rice was conducted at Kapangsean Campus of Kasetsart University between January - April 1984. The different land preparations were 1) tillage; 2) no-tillage + straw burned; 3) no-tillage + no straw burned, and 4) no-tillage + rice stubble left over; and three planting methods of 1) drill planting, 2) hill planting, and 3) broadcasting were alternatively arranged into eight treatments. Soybean variety S.J. 4 was planted using the seeding rate of 62.5 kglha. The result of the study indicated that no-tillage + straw burned method provided efficient weed control measures as similar to the tillage operation. Without straw burning, weed infestation was high. The yield of soybean in the tillage plots was higher than no-tillage + straw burned treatments, because tillage provided a better root condition for soybean growth. The yield of no-tillage + no straw burned was low due to weed infestation. Seed size of soybean on no-tillage + no straw burned was smaller than those of other treatments due to weed infestation at the later stage of plant development.
