ABSTRACT
The result and quality of soybean seed (Glycine max (L.) Merrill) is still low, it is
necessary to improve the quality of seed yield, one of them is through the
improvement of cultivation technique using rhizobium bacteria inoculation
application as well as providing nutrient in take of nitrigen (Urea). The purpose
of this study was to determine the results and quality of soybean seeds by
inoculation treatment of rhizobium bacteria and dosage of Urea fertilizer. This
research was conducted in September 2016 - February 2017 using Randomized
Complate Block Design (RCBD) with 2 factors. The first factor (R1) = 5 gr, (R2) =
6 gr, (R3) = 7 gr and (R4) = 8 gr Rhizobium / kg seed, Second factor (N1) = 25 kg,
(N2) 50 kg Urea / Ha. The observational data were tested using DMRT with 5%
level. The parameters observed were flowering age, plant height, number of root
nodule, number of branches, number of pods, crop yield, 100 grain weight, seed
germination rate, seed growth rate, and seedling simultaneity. The results showed
that the best treatment was (R2) = 6 gr and (R4) = 8 gr of rhizobium / kg seed,
significant effect the number of root nodules and number of pods. (N2) = 50 kg
Urea / ha, significant effect on the number of root nodule (N1) = 25 kg Urea / ha,
significant effect on crop yield and 100 grain weight.
