Utilization of goat manure fertilizer with TSP fertilizer for the growth and production of red beans (Phaseolus vulgaris L.) and its impact on the environment

Abstract

The research was conducted in Negeri Bayu Muslimin, Kab. Simalungun. The research aims to determine the effect of goat manure and TSP on the growth and production of red bean plants. The research used a Randomized Block Design (RBD) with 2 factors. The first factor was the dose of Goat Manure Fertilizer (K) with 3 levels: K1= 5 tons/ha (1kg/plot), K2= 10 tons/ha (2kg/plot), K3= 15 tons/ha (3kg/plot). The second factor was the dose of TSP Fertilizer (P) with 4 levels: P1= 50kg/ha (10g/plot), P2= 100kg/ha (20g/plot), P3= 150kg/ha (30g/plot), P4= 200kg/ha (40g/plot). Parameters observed include plant height (cm), number of branches, number of pods per plant (pods), number of pods per plot (pods), wet pod weight per plot (g), and dry seed weight per plot (g). The research results show that the treatment of goat manure and TSP fertilizer doses has a significant effect on all observed parameters. The best dose of goat manure is 15 tons/ha (3 kg/plot), while the best dose of TSP fertilizer is 200 kg/ha (40 g/plot). The best combination of goat manure and TSP fertilizer is 15 tons/ha (3 kg/plot) of goat manure and 200 kg/ha (40 g/plot) of TSP fertilizer.
