Title Of Article :
THE RELATIONSHIPS BETWEEN SALINITY LEVELS OF WATER USED FOR IRRIGATION WITH YIELD AND QUALITY PARAMETERS IN RED PEPPER (Capsicum annum cv. Kapija)
Abstract :
This study was conducted to determine the effect of saline irrigation water applications on yield and fruit quality of red pepper. Research was laid out in randomized parcel design with six replication and 12 plants in each replication on lysemeters formed in greenhouse. Plants in the lysemeters were irrigated with tap water [control, electrical conductivity (EC): 0.3 dS m-1] or salinized water [EC: 1.5, 3.0, 4.5, 6.0 and 7.5 dS m-1]. Research results showed that the yield and paste output decreased with increasing salinity above 1.5 and 3.0 dS m^-1, respectively. Dry matter, total acidity, total karotenoid contents for pepper fruits were significantly increased up to 6.0 dS m^-1 and the soluble solids, total sugar, protein, lycopene gave the highest contents at 4.5 dsm^-1, but their values were decreased with increasing salinity of above mentioned levels. In this study, vitamin C contents were highest at control and 1.5 dS m^-1 salinity levels. Vitamin C content of fruit on peppers was significantly decreased by of irrigation with saline waters having the concentrations of 3.0, 4.5, 6.0 and 7.5 dS m^-1. Considering the quantity and quality for red pepper production, the water salinity of the irrigation of 1.5 dS m-1 for fruit yield, 3.0 dS m^-1 for paste yield, and 4.5 dS m^-1 for fruit quality characteristics can considered as threshold values.
