Abstract

The main aim of this investigation was to determinate the effect of drip fertigation on
hydofphytotermical coefficient of two stem pruned pepper crop (“V”system). The field experiments
were conducted with green pepper crop ‘Bela dolga’ grown in experimental plastic house near by the Faculty of Agricultural Sciences and Food in Skopje, during the period of May to October in 2005, 2006 and 2007. Therefore, four experimental treatments were applied in this study. Three 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 (control treatment ØB). From the results obtained during the three years of investigation, it can be concluded that the average hydrophytotermical coefficient in 2005 is 1.52 in 2006 the coefficient is decreasing (1.46), while in 2007 hydrophytotermical coefficient again is increasing (1.48). According to year of investigation, the treatments with drip fertigation (KK1, KK2, KK3) shows from 14.6 to 23.6% lower average hydrophytotermical coefficient in comparison with treatment with furrow irrigation and traditional application of fertilisers ØB.
