Abstract

Peanuts are a potential commodity to be developed in Indonesia after soybeans and green beans. Low peanuts seed production is an existing problem that must be solved, with one of the ways is fertilizing bokashi and P. The purpose of this study is to determine the effect of the interaction of bokashi and P fertilizer application on yield and seed quality of peanuts (Arachis hypogaea L.). The experiment was started from Desember 2016 to April 2017, at the Ciparanje Experiment Field and Seed Technology Laboratory of the Faculty of Agricalture, University of Padjadjaran, Jatinangor, Sumedang, West Java. The experiment design used is a pattern of factorial randomized block design with two factors and three replication. The first factor is the dose of bokashi fertilizer with three levels, 0 5, 10 ton ha-1 and the second factor is the dose of P fertilizer with four levels, 0, 50, 75, 100 kg ha-1. The result showed that there is no interaction between bokashi and P on all of parameters. Application of Bokashi fertilizer and P fertilizer significantly on yield but not significantly on seed quality parameter. Bokashi fertilizer has an effect on increasing the weight of seeds per plant. Bokashi fertilizer with dose 5 ton ha-1 gave the best influence to the weight of seeds per plant. Effect of application of P fertilzer with dose 50 kg ha-1 gave the best effect on harvest index parameter. Keywords: bokashi, peanuts, phospahate fertilizer, seed quality

Abstract

The variation of the seed size in each species and individuals might be from of difference species adaptation for  a difference environment. This difference may also arise from the constraints of limited formation of seed size. The use of adaptive ciltivars on the growth environment is very influential on the succes in the farm field. This research was aimed to find the adaptation of phase and size seed of two cultivars of soybeans in Jatinangor and Cikajang. This research was held in Jatinangor (Sumedang regency) and Cikajang (Garut regency) from April to July 2016. The design that used in this research was Randomized Block Design (RBD) and Duncan at 5% rate. Improved cultivars that tested in this research were placed at Grobogan and Anjasmoro which were repeated 5 times. The results of experiment showed that adaptation of size seed showed of 100 grains and large seeds. The low temperature condition can increase of variability of seed size. Heterogeneity of environment can not sustain the size of soybean seed. Genetic and environment factors influence significantly for weight of 100 grains and seed size Grobogan in Jatinangor. The weight of 100 grains Grobogan in Jatinangor and Cikajang haved a greater than Anjasmoro. Environmental factors influence yield of soybean, weight of 100 grains of cultivars in Cikajang haved a greater than Jatinangor caused by the seed size.
