Abstract :
The primary objective of this study was to identify the influence of irrigation and fertilization regime on some phenological stages and earliness of pruned pepper grown in plastic house. We applied four experimental treatments in this study. Three of the treatments were irrigated with drip irrigation and drip fertigation (KK1, KK2, KK3), while the last one was irrigated with furrow irrigation and conventional application of fertilizer (ØB). From the results obtained during the three years of investigation, we can conclude that treatments with drip fertigation frequency of every 2 and 4 days (KK1 and KK2) and drip fertigation scheduled by tensiometers (KK3) shows from 4 to 10 days earlier initial technological maturity in comparison with ØB. Results indicate that drip fertigation is an effective practice to achieve earlier yield. Namely, the drip fertigation treatments show from 19.34 to 38.89% higher earliness index compared with ØB. Similar results were obtained for marketable yield, e.g. the lowest yield was obtained in treatment ØB, while the highest one in treatment KK1.
