Abstract

This research was conducted in Balai Benih Utama (BBU) of Sungai Rumbio Kari, Kuantan Tengah district’s, Kuantan Singingi Regency. The purpose of this research is to know the effectof solid plus plus (kosplus) compost on growth and production of beanplant (Vignasinensis L.) onultisol. The research method used is Non-Factorial Randomized Block Design (RAC) Non Factorialie Solid Plus Compost (Kosplus) consisting of 6 treatment levels and 3 replications. Treatment A = 10 ton cosplus, B = 20 ton cosplus, C = 30 ton cosplus, D = 20 ton of solid compostalone, E = 100% Artificial Fertilizer, F = No Fertilization. Each experimental unit consistsof 6 plants and 4 ofthem as sample plants. The data were analyzed statistically, with advanced test of real honest difference (BNJ) at 5% level. Based on the result of the research, it can beconcluded that the effect of solid plus compost (kosplus) on ultisol soil gives a real effect to long bean plant with plant height 346,67 cm, flowering age 33,00 day, podlength 64,42 cm and weight off reshpod 806.18 grams/ plant. The best treatmentis in C treatment (30 ton cosplus / ha).
