USE OF HORSE MANURE COMPOST FOR INTEGRATED NUTRIENT MANAGEMENT IN MUNGBEAN

Excessive use of nitrogen fertilizer in Indonesia along with detrimental effect of high nitrogen application rate to atmosphere, ground and surface water, as well as to quality of harvest has led to attention in the integrated nutrient management (INM) approach. The study is aimed at exploringthe possibility of using compost made from horse manure in INM for mungbean production. Compost made from horse manure at rate 0, 50, 70, and 90 g plant-1 in combination of NPK compound fertilizer at rate 0, 10, and 20 g plant-1 were tested on growth and yield of mungbeanusing Randomized Block Design field experiment. The result shows that combination of 90 g plant-1 manure with 20 g plant-1 NPK give the highest yield which is 1.42 ton ha-1 . Hence, horse manure compost can be used as organic component in INM to substitute partly inorganic fertilizer.
