Growth and Productivity of Lurik Peanuts ( Arachis hypogaea L. var. Lurikensis) after Biofertilizer-Sludge Biogas Application

Abstract

One of the most important crop commodities in Indonesia is peanut. Ipeanutse peanut production can be done in various ways, including plant breeding, and improving land quality through organic fertilization. The effect of the use of biofertilizer combined with sludge on crop productivity of peanuts, especially peanuts from the breeding products has still not been widely studied. This research aims to analyze the growth and productivity of breeding peanuts which is Lurik Peanuts or striated peanut. The treatment given to Lurik peanuts were 15 levels of concentration of biofertilizer and sludge combination then compared to Lurik peanuts cultivated without the treatments. There were 16 plots used for each treatment. The parameters observed including of plant height, number of leaves, wet weight of shoot, root, and pods, and also the number of pods per plant. The result obtained was biofertilizer-sludge is significantly affected the height of the plant, number of leaves, wet weight of shoot, root, and pods, and also the number of pods per plant. The conclusion was that the application of each biofertilizer and sludge treatment or a combination of the two significantly affected the increase in plant height, but did not affect the number of leaves parameter significantly. The sludge application and the combinations of sludge-biofertilizer effect the shoot and root wet weight, the weight of the wet pod, and the number of pods per plant, but does not affect the real by application biofertilizer.
