Abstract

Animal manure is a renewable natural resource as a biological fertilizer whose quality can be improved through various strategies. Research on fertilization strategies was carried out to get the best level of cow manure-manure compost enriched with various types and inorganic fertilizers doses on growth, production, and king grass (Pennisetum purpuphoides) carrying capacity. The study consisted of 9 treatments, namely enrichment of inorganic fertilizers Urea, NPK, and ZA in dairy cow manure with several doses equivalent to urea as much as 100, 200, and 300 kg per hectare per defoliation. The study was carried out on plots measuring 2 x 1.5 m² which were carried out on the second defoliation. The variables studied included growth, fresh production, and carrying capacity for cattle or large ruminants. The data obtained were analyzed based on a completely randomized design. The significance of differences was tested by orthogonal and regression. The results showed that dairy cow manure can be enriched with inorganic fertilizers up to a level of 300 kg equivalent to urea and has provided growth, fresh production, and high carrying capacity of king grass (Pennisetum purpuphoides). The average plant height is 195 cm, the number of plants is 16.37 stems per clump, the production of fresh forage is 17.08 kg per 3 m² or 512,400 kg/ha/year and the carrying capacity for large ruminants is 40.67 animal units (AU).
