PENGARUH DOSIS PUPUK UREA DAN PUPUK ZK TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KACANG PANJANG (Vigna sinensis L.) VARIETAS PARADE

Yard long bean (Vigna sinensis L.) is an annual vegetable plant that grows vines, upright and requires tillers to support its growth. The national productivity of long beans (Vigna sinensis L.) is only around 352,700 tons. Long bean production cannot meet the needs of the community which continues to increase every year, to develop long bean cultivation it is necessary to increase the production of long beans. Efforts to increase the yield and production of long beans are the use of appropriate fertilizers. This study aims to determine the effect of the dose of Urea fertilizer and the dose of ZK fertilizer on long beans (Vigna sinensis L.) Parade variety. This study used a Randomized Block Design (RAK) arranged in an orthogonal factorial contrast with two treatment factors and three repetitions. The first factor is the dose of N (Urea) fertilizer which includes N1 (20 gr Urea/plant), N2 (15 gr Urea/plant), N3 (10 gr Urea/plant), while the second factor is K (ZK). 12 g ZK/plant), K2 (8 g ZK/plant), K3 (4 g ZK/plant) and plants without treatment (control). Based on the results of the study showed that there was an interaction between the dose of Urea fertilizer and ZK fertilizer had a significant effect on the variables of plant height, number of leaves, stem diameter, number of flowers and variable weight per plant, weight per plant. hectare with doses of N2 (15 g Urea/plant) and K1 (12 g ZK/plant). The dose of urea fertilizer had a significantly effect on the growth and yield of long beans (Vigna sinensis L.) Parade variety. ZK fertilizer dose treatment significantly affected the growth and yield of long beans (Vigna sinensis L.) Parade variety. Meanwhile, between treatment and control there was a significant effect on long beans (Vigna sinensis L.) Parade variety
