Abstract:

Fertilization with NPK fertilizers had a great effect on peanut pod rot infection during two successive seasons 2002 and 2003. Increasing K fertilizer level singly or in combination with P specially decreased the infection with pod rot. Meanwhile, using N fertilizer singly at the high level increased pod rot infection while, using P and K: fertilizers with high lefel in combination with N fertilizer decreased pod rot infection to moderate levels. Moreover, nc addition of K in presence of high levels of N increased the percentage of break down and brown rot as well as pink rot comparing with the treatments applied with K at high units. Addition of NPK fertilizers at all tested levels increased the yield of peanut pods. The best irrigation system was spray system where, it reduced the infection with total pod rot, pods break down, brown and pink rots. Drip irrigation system caused the highest total peanut pod rot especially in Sharkya and also increased pods with break down, brown and pink rots in this governorate. Early sowing of peanut during the Is April decreased severity of pod rot and then reduced the infection of pods with break down, brown and pink pods in two governorates (Beheira and Sharkya) during two growing seasons (2002 and 2003). It is pronounced also that delaying the sowing time after I81 April, increased gradually the pod rot infection to reach their maximum infections during the two seasons in the two governorates at Is1 June.
