Difference in planting time lag after rice harvesting on growth and yield of no tillage soybean (Glycine max L.)

Increasing soybean yields needs to be done with innovation in cultivation techniques, one of which is by applying the right planting time. This study aims to obtain planting time that can increase the growth and yield of soybeans in a system without tillage. The study was conducted from June to September 2019 on the former rice field land. This research was conducted using a Randomized Completed Block Design 1 factor with 5 treatments (2, 4, 6, 8 and 10 days after rice harvest) and repeated 5 times. Data from observations were analyzed using analysis of variance based on the 5% F test followed by Duncan's Multiple Range Test of 5% and a correlation test was performed to determine the relationship between soybean planting time difference and the yield. The results showed that the difference 2 days after harvest was able to increase the growth variables, namely plant height, leaf area, number of branches and increase the yield variable, namely the number of pods, seed weight per plant, seed weight per plot. Besides increasing soybean yield to 1.41 tons / ha compared to a longer gap.
