Abstract

A study aimed to examine the effect of combination of cow manure and NPK fertilizer, and to determine the best combination of fertilizer doses on growth and yield of cowpea. The research was carried out in a plastic house in Sleman from September to December 2014. The design of a 3 x 4 factorial experimental study was arranged in a Completely Randomized Design with three replications. The first factor is dose of cow manure (K), consisting of three levels (K1: 10 tons/ha, K2: 15 tons/ha and K3: 20 tons/ha). The second factor is the dosage of NPK fertilizer (D), consisting of four levels (D1: 0 kg/ha, D2: 75 kg/ha, D3: 100 kg/ha, and D4: 125 kg/ha). The observational data were analyzed variance by the F test at 5% level of trust, and to test the difference in treatment effect, using Duncan's Multiple Range Test (DMRT) at 5% level of trust. The result of experiment showed that the combination of cow manure and NPK fertilizer had significant effect on plant height, branch number, flowering age, pod number, pod weight. The real interaction between treatments is shown in the number of pods. Meanwhile, K3D3 that is combination of dosage treatment of cow dung 20 ton/ha and dosage of NPK 100 kg/ha fertilizer, showed as the best treatment combination effect on crop production of cowpea which is 70 dap. Keywords: cowpea, cow manure, NPK fertilizer
