PENGARUH VARIETAS DAN WAKTU PENYEMPROTAN PESTISIDA TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KUBIS (BRASICCA OLERACEA L.) DATARAN RENDAH

This study aims to determine the effect of the variety and time of pesticide spraying on the growth and
yield of cabbage plants. This research was conducted in Keleke Village, Dolo Barat District, Sigi
Regency, Palu, which took place from July to September 2022. This research used a Randomized Block
Design (RBD) consisting of 2 factors. The first factor was the cabbage variety consisting of (V1) K-K
Cross, (V2) CR Ace and (V3) Green Gem. The second factor is the time of spraying which consists of
(S1) spraying in the morning, (S2) spraying during the day and (S3) spraying in the afternoon. Each
treatment combination consisted of 3 replications to obtain 27 experimental units. Based on the research
results, it can be concluded that there was no interaction effect between varieties and pesticide spraying
time on all observed parameters. There was an influence of variety on the parameters of crop weight and
crop volume at 45 HST, with the K-K Cross (V1) variety treatment but had no effect on other parameters.
The timing of spraying pesticides had an effect on the crop volume parameter at 45 HST, with the time of
spraying in the afternoon (S3) but had no effect on other parameters.
