Growth and results response of two soybean varieties toward fertilizing package at acid dry land in Aceh Province

Acidic dry land is a potential suboptimal land as a source of agricultural production with proper management and utilization. The aim of this research is to determine the growth response and soybean yields of Kipas Merah and Demas varieties to several fertilizer packages. This research was conducted in July to October 2018 in Pidie Jaya Regency of Aceh Province. The study design used a randomized block design (RBD) with 3 replications and in each treatment set 15 plants as samples. The first factor is the variety (V), that is V1 = Kipas Merah; V2 = Demas. The second factor is fertilization package (P) consisting of 2 (two) levels: P1 (specific location) (2 tons/ha organic fertilizer, ameliorant 500 kg/ha and NPK 150 kg/ha); P2 (Recommendation) (urea 75 kg/ha, SP-36 100 kg/ha, KCl 100 kg/ha, ameliorant 500 kg/ha). The results showed the Demas variety with the recommended package gave the highest production of 1.97 tons/ha.
