PENGARUH PEMBERIAN DOSIS PUPUK N DAN P TERHADAP PERTUMBUHAN DAN HASIL KACANG PANJANG (Vigna Sinensis L)

Abstract

The purpose of this research is to know whether the influence of using fertilizer N and P dosage towards the growth and yield of long beans (vigna sinesis L). This research was carried out in Onelako Village, Ndona subdistrict of Ende regency. The method used was Randomized Block Design with two factors of treatments and three replications. The first factor is nitrogen fertilizer which consists of three dosages namely N0: (non-nitrogen fertilizer), N1 (30 kg/ha), N2 (60 kg/ha) and second factor is phosphor fertilizer which comprises three dosage: P0 (non-phosphor fertilizer)), P1 (50 kg/ha) and P2 (100 kg/ha). Observation variables are the diameter of the rod, leaf number, leaf area, pods length, pods diameter, pods number, fresh weight of pods/plants, fresh weight of pods/ha, fresh maximal yield and residues/ha and harvest index. The result showed that no interaction between two factors of treatment (N x P). Nitrogen fertilization treatment of 60 and phosphor with a dosage of 100 kg/ha (P2)  produce the best yields towards all observed variables.  The yields of fresh weight of pods per highest plant is 62,56 gr acquired from plants which get N2 and P2 fertilizer. However, the treatments between N1 and N2 do not have a real difference in all observation variables as well as treatment of P1 and P2.
