Abstract

This study as a phase I research was carried out on farm (in situ) in the farmer's coconut (Cocos nucifera) land with different designs every year. In this study, the treatments are dwarf elephant grass (Penisetum purpureum cv. Mott) planting and the use of organic fertilizer processed from cattle manure and coconut waste. The variables that become the parameters of technical productivity were measured in first year of three years of research, namely the amount of fresh forage production of dwarf elephant grass, the amount of nuts per coconut bunch, and the stocking rate of forage forages in coconut fields in the Coconut and Beef Cattle Integrated Farming System (Coco-Beef IFS). The results of the study as follows: (1) Productivity of Pennisetum purpureum cv. Mott in coconut field that has been fertilized with cattle manure based compost, produces the yield of fresh forage per year can reach 661,947.64 kg per hectare per year, then the stocking rate of grass Pennisetum purpureum cv. Mott per hectare of land under coconut trees can be given to around 45.34 heads of adult cattle a year; and (2) Production of coconut (Cocos nucifera) around 7.88±2.44 nuts or in average about 8 nuts per bunch in land planted with Pennisetum purpureum cv. Mott and fertilized with cattle manure-based compost. Coconut productivity is seen in two parameters (around the bunches and number of coconuts) in the first year of study is still low. The results of the influence of cattle manure-based compost fertilizer on several parameters of coconut productivity are expected to increase in the second or third year of research to be conducted later.
