Abstract

Dryland has the potential to increase agricultural production, by increasing the cropping index. The main problem of dryland is the availability of water which depends on rainfall. Groundwater can be an alternative option to meet the availability of water in the dryland. This study aimed to determine the cropping pattern and increase of cropping index supported by groundwater irrigation in the dryland. The research was conducted in the dryland of Playen, Gunungkidul, Special Region of Yogyakarta, supported by groundwater irrigation. This research used a combination of survey, interview and plot demonstration methods. Surveys and interviews were conducted to determine the condition of cultivation and profit in the first and third growing seasons. The plot demonstration, to increase the rice cropping index from 1 to 2, was applied in the second growing season. The results showed that rice productivity in the first growing season was 5.215 ton ha-1, with a profit of 12,288,000 IDR ha-1 and B/C of 1.28. In the second growing season, Sidenuk productivity was 8.025 ton ha-1, with the dry straw of 8.049 ton ha-1, grain carbon of 3.471 ton ha-1 and straw carbon of 3.723 ton ha-1, higher than those of Situbagendit, but comparable those of Inpari-42, with a profit of 20,700,000 IDR ha-1 and B/C of 1.54. Rice contributed to higher biomass, carbon and profit than groundnut. In the third growing season, groundnut productivity was 2.026 ton ha-1, with a profit of 15,572,000 IDR ha-1 and B/C of 1.78. Groundwater irrigation can support the increase in the cropping index on dryland and intensify agricultural production as well.

Abstract

Soybean is a highly nutritious and strategic food. The harvested area and production of soybeans tend to decrease, not sufficient for national needs, which must be met through imports. Breakthroughs are needed to develop soybean, with specific strategies to adapt to particular conditions, including in Gunungkidul Regency. This study aimed to reveal the soybean development strategies in the dryland agroecosystem in Gunungkidul Regency. Survey and interview methods were used in this research, supported by secondary data analysis and data from the previous year's research. The correlation analysis was used to determine the decrease in harvested area. Other data were analyzed descriptively. The results showed a significant decline in soybean harvested area between 2009 to 2020. The soybean development strategy is area-based, from upstream to downstream, involving both main soybean products and by-products. Soybean planting was carried out in the first, second and third growing seasons, using site-specific soybean cultivation technology, providing seeds through the Jabalsim System supported by irrigation. Policies are needed within the organization's scope, rules, guidance and protection. The final results of this research are embodied in the form of an area-based soybean development diagram in Gunungkidul Regency, which can be used as a development reference.
