Abstract


The objective of this research was to study the response of two soybean varieties growth and yield
on the biofertilizer and NPK compound fertilizer application. The factorial randomized block
design was used in this research with three factors i.e. : varety (Anjasmoro and Grobogan),
biofertilizer    (0, 50 and 100 kg/ha) and NPK fertilizer (0, 125, and 250 kg/ha). This research was
conducted on the experimental field of North Sumatera University from April to August 2014. The
results showed that varieties significantly affected the plant height (2, 3, 4 and 6 weeks planted, the
leaf greeness level, time of flowering, the time of harvest, the number of productive branches, the
number of pods per sample, the number of seeds per sample and the dry weight of 100 seeds.
Biofertilizer unsignificantly affected on all parametres. The NPK compound fertilizer significantly
affected the the plant height 5 weeks planted, the leaf greeness level and the number of seeds per
sample. The interraction between variety and biofertilizer singnificantly affected the time of
flowering, however the interraction between variety and NPK fertilizer affected the time of
flowering and the number of seeds per sample.
Keywords: soybean, variety, biofertilizer and NPK fertilizer.
