ABSTRACT
One method to increase production of onion is using the tuber size and addition
biourine. The purpose of this research was to know the effect of tuber size and
biourine concentration on growth and result onion tubers. This resarch did in
August until October 2016, in farmland State of Polytechnic Jember. The research
did with using a randomized block design(RAK) consist two factors and three
replications.The first factor is tuber size and second factor is biourine
concentration. Factors of tuber size consist from three levels, that is U1 = small
tuber (Ø = <1.5 cm or <5 g/tuber), U2 = medium tuber (Ø = 1.5-1.8 cm or 5-10
g/tuber), U3 = large tubers (Ø => 1,8 cm or >10 g/tuber. Factors of biourine
concentration was consist three levels, that is B1 = concentration of 50 ml / liter,
B2 = concentration of 75 ml / liter, B3 = concentration of 100 ml / liter.
Observation data on each parameter analyzed using the formula F test (ANOVA)
followed by a further test BNT 5%. Result of this research showed that treatment
of tuber size give a significant effect on the observation variables plant height and
number of leaves at 14 and 28 days after planting. Treatment of tuber size give
significant effect on Weight parameters of wet tube, dry tuber and number per
clump parameter too. While treatment of concentration biourine give significant
effect on tuber diameter parameter. For the interaction between tuber size and
concentration biourine dont give significant effect on all parameters of
observation.
