Studi Penggunaan Pupuk Hayati Pada Tanaman Kedelai

Abstract

Study of the use of biological fertilizers on soybean. One of the efforts to improve the
growth and yield of soybean is to utilize biological fertilizer in the form of inoculants,
both root nodule bacteria and endophytic bacteria. Assessment carried out on land
formerly used for rice cultivation in Palangki, District Ampek Nagari, Sijunjung
regency, West Sumatra, in the dry season (June to September 2010). The design used
was a randomized block design (RBD) with 4 treatments and 4 replications, plot size
of 5 x 4 m, using Anjasmoro soybean varieties, spacing of 40 x 10 cm, each planted 2
seeds / hole. Treatment in this study, namely: Land given lime without bacterial
inoculation (A1); Land without lime, and soy beans inoculated bacteria (A2); Land
given lime and soy beans inoculated bacteria (A3); and Land sown with soybean
planting land former, given lime and seeds not inoculated bacteria (A4). Data were
collected for plant height, number of primary branches, total number of pods, number
of pods, amount number of seeds, seed fresh weight and dry weight of seeds. The study
showed that treatment of ex-land sprinkled with soybean planting, and seeds were not
inoculated lime and (A4) gives the highest response for each parameter of observation
compared with other treatments.

Keywords: soybean, bio-fertilizers, bacteria.
