Improper soil tillage management often leads to soil degradation that eventually decreases rice productivity. The aim of the research was to identify the best soil tillage management and planting systems to improve rice productivity and vertisol properties in a rainfed agroecosystem. The field experiment was laid out as a split plot design with two planting systems of direct seeding (DS) and transplanted seeding (TS) treatments as the main plot and three soil managements treatment, i.e., no tillage (NT), minimum tillage (MT), and conventional tillage (CT) as sub-plots and four replications. The results showed that vertisol properties such as bulk density, porosity, and permeability tend to be better in NT and MT than in CT, although these were not significantly different. However, rice plants were harvested about 10 days earlier in the DS treatment than in the TS treatment without significantly reducing yield. The DS technology has been able to streamline the planting time earlier than the usual method or the farmer's method (TS) with NT or MT soil management. The agronomic parameters of rice plants did not significantly differ either in combination treatments or in single treatment except for dry biomass weight. The highest dry biomass was obtained in the conventional tillage treatment and was significantly different from the treatment with no tillage but not significantly different from the minimum tillage. The cultivation of no tillage combined with direct seed planting was able to produce the same rice yield as transplanted seed with conventional tillage. The existence of earlier planting time will provide an opportunity to utilize irrigation water resources more efficiently for the next season of planting time. [ABSTRACT FROM AUTHOR] |
