Effect of Cattle Manure and Mycorrhiza on Medicinal Pumpkin

In order to evaluate the impact of cattle manure and mycorrhiza fungi on pumpkin plants (cucurbita pepo con Var.styriaca) under water deficit stress conditions, a split-factorial design was conducted as base of randomized complete block design with four replications. Irrigation interval (at three levels: 60, 120 and 180 mm based on cumulative evaporation from class A pan) as main plots that exerted on pre-flowering, cattle manure (at three levels: 0, 15 and 30 t/ha) and mycorrhiza fungi (at two levels: with and without application) as sub plots were considered. The results showed that irrigation factor had significant effect on grain number, grain yield, fruit yield, fruit diameter and fruit pericarp diameter. so that irrigation after 60 mm evaporation caused to increase fruit yield and fruit pericarp diameter. Whereas irrigation after 120 mm evaporation had most grain number and grain yield. The manure treatment had significant affect on fruit yield and fruit pericarp diameter. So that consumption of 30 t/ha manure led to significant increase on these traits. Mycorrhiza fungi had significant effect on grain number and grain yield.
