Effect of bio-slurry fertilizer and chicken manure on growth and yield of green bean in latosol

Abstract

In general, latosol soil has a low nutrient content and organic matter, while the productivity of the soil is from moderate to high. The purpose of this study was to determine the growth and production of green beans planted with bio-slurry and chicken manure on latosol soil. This research was conducted at the Screen House of Agrotechnopark, Faculty of Animal Husbandry and Agriculture, Diponegoro University. This study use a completely randomized design with factorial patterns and three replications. The first factor is bio-slurry fertilizer, namely 300 kg ha−1 (P1), 600 kg ha−1 (P2), and 900 kg ha−1 (P3), while the second factor chicken manure is 0 kg ha−1 (A0), 200 kg ha−1 (A1), 400 kg ha−1 (A2) and 600 kg ha−1 (A3). This research using 12 treatment combination, in which each treatment was repeated five times. Therefore, the total experimental unit were 60 units. The results of the analysis of variance showed that the treatment of bio-slurry fertilizer and chicken manure significantly affected (P<0.05) the number of leaves, number of pods, pod length, weight of 100 grains and weight of seeds per plant. There was no interaction between the treatment of bio-slurry fertilizer and chicken manure for all observed parameters. The highest number of leaves each was obtained from the treatment of bio-slurry fertilizer 900 kg ha−1 (25.46 strands) and 200 kg ha−1 chicken manure treatment (27.70 strands). The treatment of bio-slurry fertilizer up to a dose of 900 kg ha−1 yielded the highest number and length of pods of 16.08 and 13.92 cm respectively. While the highest seed weight per plant of 7.50 g was obtained from bio-slurry fertilizer treatment at a dose of 900 kg ha−1.
