Abstract
North Sulawesi is one of the production centers of cattle as well as maize in Indonesia. On the other hand, there is problem in cattle grazing decrease causing some farmers cultivate maize as a forage, even though this it is still cultivated carelessly so that the biomass productivity is low. This study aimed to evaluate the use of applied innovations in maize cultivation as forages. The Demonstration plot was conducted in Kembuan, Minahasa Regency at elevation of 700 m above the sea, in June-October 2019. The method used Technology Display, where the innovation package included recommended maize cultivation such as superior seeds, fertilizers, pesticides and tractor using. Fertilizing in 12 dap, Urea 250 kg + NPK (15-15-15) 150 kg, then in 60 dap, Urea 125 kg and NPK (15-15-15) 100 kg. Weeding using herbicides at 30dap. Harvesting as fresh forage, all biomass at 75 dap, 35.64 tons/ha with TDN content 20.54 t/ha (58%) and provided a carrying capacity 11.34 UT, providing feed along the year. Financial analysis indicated the feasibilities, ROI coefficient 2.27 and BC Ratio 1.27. It can be concluded that maize farming can be a solution of forage fodder in cattle commodity areas.
Highlights
North Sulawesi Province is one of the Indonesian production centres for beef cattle
The feed problems of cattle farming in North Sulawesi due to the habit of farmers generally applying traditional extensive-grazing system based on grazing land [5]
This study aims to evaluate the performance of implementing Integrated Plants Management, IPM (PTT- Jagung) as forage, especially on the total biomass yield, total nutrition, and forages technological package and its financial feasibilities that can be recommended as an alternative forage for cattle to solve feed problems and to support the development of beef cattle in North Sulawesi
Summary
North Sulawesi Province is one of the Indonesian production centres for beef cattle. Cattle farms in North Sulawesi are facing many problems yet, it is difficult to move from the slump in population, production, productivity and product quality [4]. The feed problems of cattle farming in North Sulawesi due to the habit of farmers generally applying traditional extensive-grazing system based on grazing land [5]. This kind of maintenance system is gradually under pressure because the dimensions of the grazing space are decreasing due to the incessant expansion of the area of food crops, industrial plants, etc
