Effect of Irrigation Regime on the Cultivation of Five Wild Colocynth[Citrullus colocynthsis (L.) Schrad.] Ecotypes in Terms of Their Growth, Seed Yield and Oil content

The objective of this research was to evaluate the response five wild colocynth (an important medicinal plant) ecotypes toirrigation regime as a basic input cultural practices. laid out in split plot design with three replications. Treatments were two irrigation regimes (Q1= 100 % Etc and Q2= 50 Etc) (G, SF, SD, GD NK). experiment run for seasons (2014 2015). Parameters measured days flowering, number fruits per plant, seeds fruit weight 1000 seeds, seed yield oil content seeds. Days %flowering not significantly affected by watering seasons; however, effective first season only. Number plant both yet, highest fruits/plant wasproduced ecotype G NK second season. lowest produced SD seasons. different between it was, among There no significant difference yields Ecotype seasons.The regarding but season.Mean percent resulting from irrigated (15.2%) higher than that collected (12.1%).Moreover, mean high low individually habitat. In habitat, (16.0%) (6.4%). When irrigated, showed differential positive response. conclusion, ectypes responded positively which is most product, indicating possibility inclusion existing cropping system thereby ensuring its conservation economic use. More research, needed todetermine, precisely, water requirement production.
