Production and quality of forage alfalfa (Medicago sativa L) with organic and inorganic fertilization

Abstract

The effect of organic and inorganic fertilizer on the quality of forage alfalfa (Medicago sativa L). The material used are alfalfa seed, land used for the research are area of 324 m2, KCl and urea fertilizer as basic fertilizer, P fertilizer as a treatment is SP 36, BP and organic fertilizers. Organic fertilizer derived from cow and goat manure, with each dose of 35 tons/ha. The research design is a randomized block design with 9 treatments and 3 replications as follows: P0: control (without P fertilizer, without organic fertilizer), P1: Manure A (cow), P2: Manure B (goat), P3: Manure ‘plus’ A, P4: Manure ‘plus’ B, P5: Manure A + BP, P6: Manure B + BP, P7: Manure A + SP-36, P8: Manure B + SP-36. The observed parameters were forage dry matter production, crude protein content and crude fiber content. The data was analysed by analysis of variance, followed by Duncan test. The results showed that manure ‘plus’ produce higher dry matter production than manure and manure A/B + SP 36 in the second cutting. Manure A/B + SP 36 fertilizer produce equal crude protein and crude fiber content to manure ‘plus’ both in the first defoliation and second defoliation.
