Abstract

This study aims to determine the effect of various types and concentrations of organic fertilizers on growth and yield of beans. Research conducted at the village Margosari, Ilir subdistrict Talo Seluma, in September 2015 until January 2016. This study was a completely randomized block design, arranged as factorial. Consists of two factors: the first is a kind of liquid organic fertilizer (P) consists of four treatments namely: P1 = Liquid Organic Fertilizer Hantu; P2 = Organic Fertilizer Crystal Sampurna; P3 = Liquid Organic Fertilizer Biotrent; P4 = Liquid Organic Fertilizer Biotama. The second factor is the concentration of liquid organic fertilizer (K) consists of four treatments namely: K0 = Control; K1 = concentration of 1 ml / l of water; K2 = 2 ml / l of water; K3 = 3 ml / l of water. Each combination treatment was repeated 3 times.The study concluded (1) The treatment of liquid organic fertilizers and the interaction between the type and concentration of organic fertilizers no real effect on the growth and yield of beans, while the concentration of organic liquid fertilizer treatments was highly significant. (2) The concentration of liquid organic fertilizer 3 ml / l of water deliver growth and long beans optimal results.Keywords: organic fertilizers,beans, types and concentrations

Abstract

This study aims to determine the effectiveness of biological herbicide formulas on smallholder coffee plantations in various agro-ecological conditions, namely smallholder coffee fields in the medium plains and plateau. The study concluded that the weeds found in the medium plains coffee fields were 17 species. The dominant weeds were Cynodon dactilon 38.1%, Asystasia gangetica 19.3%, Ageratum conyzoides 10%, Borreria latifolia 5.4%, Acmella paniculata 3.3%, and Clydemia hirta 3.3%. These six types of weeds dominate the land at 79.4%. Meanwhile, in the plateau, there were 20 types of weeds. The dominant weeds were Brachiaria ramosa 17.8%, Synedrella nodiflora 10.4%, Digitaria cyliaris 8.7%, Mikania micrantha, 8.7%, Brachiaria setigera 8.5%, Dryopteris filixmas 7.8%, Ottochloa nodosa. 5.7%, Hyptis rhomboidea 4.3%, Brachiaria reptans 3.9%, and Clidemia hirta 3.5%. These ten types of weeds dominate the land for 79.3%. Herbicides formulated Unihaz 3, 4, 5, 6, and 7 were effective in controlling weeds in smallholder coffee plantations, both in the medium plains and plateau.
