GROWTH OF ARACHIS PINTOI FORAGE WHICH IS GIVEN VARIOUS OF TYPES AND DOSAGE OF ANORGANIC AND ORGANIC FERTILIZER

Abstrak

This study aims to assess the growth of Arachis pintoi forage which is given various types and doses of fertilizer and get the best level of various types of fertilizers in increasing the growth of Arachis pintoi plant. This research used to a completed randomized design with factorial pattern of two factors, the first factor is the type of fertilizer (A = Inorganic; OP = Organic Factory; BO = Bioorganic; BS = Biosluri), and the second factor is the dose of fertilizer (D0 = without fertilizer; D1 = 100 kg Nha-1; D2 = 200 kg Nha-1; and D3 = 300 kg Nha-1). There were 16 treatment combinations and each treatment was repeated 3 times, so consist of 48 experimental units. Variables observed included plant length, number of leaves, number of branches, stem diameter, leaf dry weight, stem dry weight, dry weight of total forage, leaf area per pot, and leaf/stem dry weight ratio. The results showed that there was no interaction between types and doses of fertilizer, all types of organic fertilizer produce growth of Arachis pintoi which tends to be higher than inorganic fertilizer, D1 and D2 fertilizer doses tend to increase, while D3 doses tend to decrease the growth of the pinto bean forage. Based on the results of the study, it can be concluded that there is no interaction between types and fertilizer dosage, all types of organic fertilizers produced plant growth of Arachis pintoi which tends to be higher than inorganic fertilizers, and fertilizer doses of 120-200 kg N ha-1 tend to be optimal in influencing the growth of Arachis pintoi forage.
