The effect of salinity stress and over irrigation on yield and yield components of green pepper

The goal of this study was to investigate the effect of salinity and amounts of irrigation water on yield and yield components green pepper (Capsicum annum) variety of green Hashemi in greenhouse conditions.The research was done based on factorial experiment in completely randomized design including three replications as pot planting in Gorgan University of Agricultural Sciences and Natural Resources.Irrigation water quality consist of five levels of salinity (0%, 10%, 20%, 30% and 40% of the mixing sea water and tap water) and the quantity of irrigation water consist of three levels (100%, 125% and 150% of water requirement were considered). Data were analyzed with SAS and the results showed that the effect of irrigation water quantities on length, diameter and length to diameter ratio of fruit was significant (P
