Abstract
This study was carried out at the Experimental Farm of the Faculty of Environmental Agriculture Sciences in EI-Arish. Suez Canal University. during the early summer seasons of 1999-2000 and 2000-2001. Sweet pepper (Capsicum annuum L.) plants cv. Sonar were grown in plastic greenhouse (9 x 60 m.). Irrigation water was supplied through trickle irrigation system. Five irrigation treatments were carried out as follow: (A) one irrigation per day,( B) two irrigations with the same quantity per day (half in the moming and half at evening),(C) one irrigation per 2 days. (D) two Irrigations with the same quantity per 2 days (half in the moming and half at evening). and ( E) one irrigation per 3 days. Every treatment was irrigated with the same quantity of irrigation (based on water requirement for one day), which gradually increased from December to June. Vegetative growth, yield and its components, fruit dimensions. leaves phosphorous and potassium contents, uptake of N, P and K and actual evapotranspiration (ETa) increased with increasing Irrigation water quantity. Treatment (D) gave the highest value of water use efficiency (W.U.E) followed by (B). (C), (E), (A). respectively. While, leaves total chlorophyll content, leaves nitrogen content, fruit content of total soluble solids and fruit content of vitamin (C) increased with decreasing irrigation water quantity.
