Effect of some treatments on yield and quality of sweet pepper (Capsicum annuum L.) grown under plastic houses

Abstract

Sweet pepper (Capsicum annuum L.) yield and fruit quality have been evaluated during the growing seasons of 1992-1993 and 1993-1994 under unheated plastic houses at Bousaily. The study comprised 7 treatments, 4 out of them were foliar spray nutrients (Superphosphate 1%, 2%; Magnesium sulphate 500, 1000 ppm.), water sleeves, P.E. mulch and control. The parameters recorded were yield and fruit characters i.e length, diameter, flesh thickness and average fruit weight from Dec-May. Foliar application of superphosphate 2% proved to be the best treatment among all of them followed by superphosphate 1%. These treatments led to increase significantly the total yield/plot and the same trend was true for fruit weight, length, diameter and flesh thickness in the studied months in both years while control gave the least parameters.
