Abstract

The mentoring and demonstration plot program with the application of technology carried out by the Faculty of Agriculture Universitas Gadjah Mada Team was proven to be able to increase the productivity and quality of soybeans, although some were only applied partially (not completely) from the recommended technology package, this was constrained by many factors in each mentoring area. In the Cilacap area, the demonstration plot results showed a fairly high potential reaching 2.24 tons/ha in Bantarsari, 2.94 and 3.77 tons/ha in Kawunganten, while in Majenang before harvesting soybeans showed good potential with 130-140 pods. per plant, this is of course the potential yield can reach above 3.0 tons/ha, but unfortunately it was affected by the flood due to the broken embankment, so the soybeans were inundated and damaged (rotten) in a relatively short time. The process of technology transfer and adoption that occurred went well, and many farmers gave testimony that this mentoring program was good to be developed and continued, so that under conditions according to the growing season, they would be able to show even better potential.

Abstract

The main issue with hybrid maize is its low nitrogen uptake, ranging from 30% to 50%. This study aims to improve nitrogen fertilization efficiency by selecting hybrid maize varieties in an agroforestry system. The research was conducted from January to April 2024 at the Menggoran Forest Management Resort (RPH Menggoran), Playen, Gunungkidul, Yogyakarta. A split-plot experimental design was employed, with 15 hybrid maize varieties as the main plot and urea fertilization as the subplot. The results revealed that nitrogen fertilization in the agroforestry system increased grain weight by 25%–68% compared to no fertilization. The highest grain weight was observed in the Pertiwi 6 and KS-89 Monster varieties, even without nitrogen fertilization. Meanwhile, the ADV Jago, Bomber R101, Turbo B-59, Si Tampan, and Twinn 1 varieties produced high grain weights when nitrogen fertilizer was applied.
