Abstract
The purpose of this study was to determine the variables that lead to optimum weights onion bulbs. Independent variables were observed temperature, GA3, and time. And the observed response is the weight of onion bulbs. ANOVA results of significant factorial experiment is temperature, GA3, and the interaction between temperature with GA3. The resulting response surface model? = 2.45 + 0.04918 ?1 3 + 0.18502 ?2 − 0.05215 ?2 3 − 0.09014 ?1 3?2 2 , with all the significant coefficient. ?1 3 the temperature effect on cubic, ?2, ?2 3 influence of GA3 on linear and cubic, and ?1 3?2 2 interaction the temperature effect on cubic and quadratic GA3. Variables that lead to optimum weight of onion bulbs are located in the code GA3 1.5 and cubic level of GA3 level code that is located at -1.5. Namely the provision of GA3 at 30 ppm, and the maximum value of 2.90 for response.
