Abstract

An experiment was conducted in Indonesian Research Institute for Animal Production (IRIAP) Bogor, West Java. The objective of this research was to study the production and nitrogen uptake of three short grasses species for grazing namely Paspalum notatum, Brachiaria humidicola, Stenotaphrum secundatum on different shading and fertilization. This experiment was arranged in split-split plot design. The main plot was shading level (0, 38, and 56%); sub-plot was fertilizer dosage (0, 100, and 200 kg N/ha) while sub-sub plot was grass species. Data were analyzed by analysis of variance, and continued with Duncan multiple range test (DMRT) if there were significantly different among treatments. The highest shoot production, shoot/root ratio, and crude protein content were observed on S. secundatum with 38% shading levels and 100 kg N/ha fertilizer. The higher shading level had the lower nitrogen uptake by plant, whereas the higher fertilizer dosage gave higher nitrogen uptake.     Key Words: Shading, Fertilization, Production, Nitrogen Uptake

Abstract

The integration of livestock with plantations is one of efforts to support livestock agribusiness. The large potential  land area can be used for the development of cattle. However, the low production, nutrient content and digestibility of natural grasses in the plantation are still an obstacle to increase cattle productivity. Therefore, the development of shade tolerant of forages is  one of the strategies to improve the quality and production of forages in the plantation area. This paper aims to review the role of Stenotaphrum secundatum as a shade tolerant forage in oil palm plantations in supporting cattle productivity. Biomass production of Stenotaphrum secundatum obtained was relatively high at 42,209 kg DM/ha/yr in oil palm plantations aged 3.5 years, estimated to be able to accommodate cattle of 11.8 AU/ha. With a moderate composition of nutrition, it can improve cattle growth performance with an average body condition score of 3.8. The livestock integration system by developing S. secundatum in the oil palm plantation area has a positive effect because it can reduce fertilizer and weeding costs of 4 million IDR/ha/yr. The average production of fresh fruit bunches (FFB) reaching 19.5 tons/ha/yr. It can be concluded that the role of S. secundatum in  oil palm plantations can support cattle productivity and increase palm oil production.
