A solution to solve this problem combination with fertilizers. Coffee pulp compost one example So, research was conductedto investigate NPK fertilizer and coffee on growth production shallot which Randomized Block Design withtwofactors. Firstfactor (0, 150,300, 450kg/ha) thesecondfactor (0,5, 10, 15 ton/ha).The results showed that treatment significantly affect plant height 3,5,6 weeks after planting per plot.NPK at 150 kg/ha can increase 15.32% compared no fertilization.Coffee plot.Compost 10 ton/ha 10.26% giving compost. interaction between non all parameters.
