Effectiveness of bio-slurry on the growth and production of soybean (Glycine max (L.) Merrill)

Abstract

This research was aimed to determine the effectiveness of bio-slurry fertilizer on the growth and production of soybean plants which was conducted in the Pucak village, Tompobulu District, Maros Regency, South Sulawesi from July to October 2016. The research was set in randomized block design (RBD) with 8 treatments replicated three times. Treatment used were the application of bio-slurry consisted of 8 level of concentrations, namely: control (0 mL.liter-1 of water), 3, 5, 7, 9, 11, 13 and 15 mL.liter-1 of water. The variables measured were plant’s height, number of pods, weight of 100-seed, and soybean seeds’ yield per hectare. The results of research shows that the application of bio-slurry effectively improved growth and yield of soybean (pod’s number, 100-seed’s weight and seed yield per hectare). Optimal concentration of liquid bio-slurry to obtain maximum results were 9.27 mL.liter-1 of water for the highest number of pods (68.49 pods); concentration of 8.75 mL.liter-1 of water for heaviest weight of 100 grains (14.22 grams); and the concentration 8,12 mL.liter-1 of water for the highest production of seed per hectare (23.20 quintal).
