PENGARUH DOSIS PUPUK KANDANG SAPI DAN PUPUK NPK TERHADAP PERTUMBUHAN DAN PRODUKSI TANAMAN KACANGi PANJANG (Vigna sinensis L.)

Abstract

This research was conducted in Bijawang Village, Ujung Loe District, Bulukumba Regency, South Sulawesi Province, aiming to determine the effect of the dose of cow manure and NPK fertilizer and the interaction between the two on the growth and production of long bean plants. This research was conducted using a factorial randomized block design (RAK). The first factor was cow manure consisting of 3 levels, namely cow manure at a dose of 20 tons/ha (6 kg/plot), 30 tons/ha (9 kg/plot), and 40 tons/ha (12 kg/plot). The second factor consisted of 3 levels of NPK fertilizer, namely 150 kg/ha (45 grams/plot), 200 kg/ha (60 grams/plot), and 300 kg/ha (90 grams/plot). Each treatment was repeated 3 times to obtain 27 experimental units. The parameters of this study consisted of plant length, number of pods planted, length of pods planted, weight of planted pods, production per plot, and production per hectare. The results showed that the application of cow manure at a dose of 40 tons/ha (12 kg/plot) had a better effect on plant length, which was 249.95 cm, pod weight was 370 grams, and pod length was 56.17 cm. NPK fertilizer at a dose of 300 kg/ha (90 grams/plot) had a good effect on plant length, namely 224.93 cm, pod length, and 56.04 cm. The interaction of giving cow manure at a dose of 40 tons/ha (12 kg/plot) and NPK fertilizer 300 kg/ha (90 grams/plot) had a good effect on plant length, namely 250.7 cm and pod length, which was 56.93 cm. long.
