Effect of deficit irrigation in pepper plant (Capsicum annum) var Jupiter

Abstract

This research on pepper crop conducted at the farm College of Agriculture at the University of Damascus in (2014), to compare the full irrigation and water stress using three transactions water are: full irrigation, 0.75% of full irrigation, and 60% of full irrigation, has been designed experiment in a way random sectors full, use a variety of Jupiter plant peppers, and used drip irrigation method. Has Watering process upon the arrival of soil moisture to 80% of field capacity, and even access to 100% of field capacity in the treatment of full irrigation, has been providing 75% and 60% of the irrigation provided water in the treatment of full irrigation for treatments of deficit irrigation 75% and 60% respectively.

Full irrigation treatment achieved the highest average yield of 10.566 tons / h, while the treatment 60% achieved an increase in the efficiency of water use by 29%, and an increase in percentage of dry matter by 10% as well, compared to the full irrigation.
