The purpose of this study was to determine the effect of climate elements to flowering, fruit yield, and shallot seeds. The study was conducted on Vertisol soil types at an altitude of 98 meters above sea level. The experimental design used was a Randomize Complete Block Design (RCBD) with one treatment factor placed as block treatment, which is the planting season. The treatment planting season consists of four seasons: early rainy season, early dry season, dry season and rainy season. Analysis of data used analysis of variance followed by Duncan's Multiple Range Test 5%. Correlation analyzes were conducted between elements of climate with the percentage of flowering plants, fruit weight and seed weight. The analysis showed that the dry season is the most suitable time to initiate shallot flowering. In this season, plants able to flowering as much as 76.1%. While in other seasons, shallot able to flowering also, despite in the low percentage. Temperature and photoperiodism positively correlated, with a correlation value of 0.9. While the rainfall and humidity have a negative correlation with a correlation value of -0.6 and -0.9.
