The effect of water hyacinth (Eichhornia crassipes) and Rhizhobium sp bacteria on growth and yield of peanut (Arachis hypogaea L)

Abstract

Peanut is one of the agribusiness commodities with high economic value, and is a source of protein for the population of Indonesia. National peanut production is still low, even from 2008 to 2012 it continued to decline. In 2008 peanut production. land was around 770 054 t, and in 2012 it was around 709 063 t. The average production capability is only about 1 t ha-1 dry beans. This decrease occurred by several factors, ranging from extreme climates, decreasing nutrient content, lower soil quality and pest attacks. Organic fertilizers can help improve soil quality and provide nutrients, while bacteria (Rhizobium sp) available nitrogen in the soil becomes available to plants. Purpose of the study to determine the interaction between fake water hyacinth fertilizer and rhizobium sp. Bacteria and its effect on the growth and yield of Kancil Peanut (Archis hypogea L) varieties. To determine the optimum dose of hyacinth organic fertilizer, rhizobium bacteria in each cultivar on growth and yield of peanut plants soil (Archis hypogea L) variety Kancil. The method used in this study was a randomized block design with 2 treatments and 3 replications. The first treatment is bohasi water hyacinth = dose 0 tonnes ha-1, 15 tonnes ha-1, 30 tonnes ha-1. The second treatment was rhizobium bacteria = dose 0 g 100 gr-1 seed, 5 g 100 gr-1 seed dose, 10 g 100 gr-1 seed dose, 15 g 100 gr-1 seed dose. The results showed that the independent treatment had a significant effect on bohasi water hyacinth treatment at plant height 42-49 days after planting, and rhizobium bacteria with a dose of 15 g 100 gr-1 seeds. Significantly affect plant height at 42-49 days after planting.
