Respon Pupuk Hayati Iletrisoy Terhadap Pertumbuhan Dan Hasil Tanaman Kedelai

Abstract

Iletrisoy a biological fertilizer that contains nitrogen fastening bacterial isolates for soybeans in the land sour and non- sour. This assessment was conducted to determine the effect of biofertilizers iletrisoy on growth and yield of soybean plants. Assessment was conducted in farmers' fields in the Bumi Setia village, Seputih Mataram Subdistrict, Central Lampung District from April to July 2013. Used a randomized block design with factorial, six replications. The first factor was the soybean varieties, namely A). Anjasmoro and B) Tanggamus. The second factor was the inoculant Iletrisoy 1) Inoculation Iletrisoy and 2) Without inoculation Iletrisoy. Iletrisoy treatedas a seed treatment (5 g / kg seed). Ploting of observation 5 meters x 2 meters. Parameters measured were growth rate, pests attack, plant height at harvest, number of branches / plant, number of pods / plant, empty pods, pod borers attacked andyields. The results showed that there was an  interaction between varieties with inoculant iletrisoy on plant height, number of branches, the percentage of empty pods, attack of bean fly, armyworm attack and bean leaf roller. The yields of soybean that Iletrisoy inoculated 6.85-7.38% higher compared to without inoculation, though it was not significant.Keywords: soybean, biofertilizer, iletrisoy
