Abstract
Two greenhouse experiments were carried out at The Experimental Farm of the Faculty of Environmental Agriculture Sciences, in EI-Arish, Suez Canal University, during 1999-2000 and 2000-2001 early summer seasons. Sweet pepper (Capsicum annuum L.) plants cv. Sonar were grown in plastic greenhouse (9 x 60 m.) under drip irrigation system. The main object of this research was to study the effect of some irrigation treatments on sweet pepper growth and yield. Also, it included the effect of these treatments on soil moisture distribution and sweet pepper actual evapotranspiration. Five irrigation treatments were carried out as follow: Treatment A: one irrigation per day, treatment 8: two irrigations with the same quantity (half in the morning and half at evening) per day, treatment C: one irrigation per 2 days, treatment D: two irrigations with the same quantity (half in tfle morning and half at evening) per 2 days, and treatment E: one irrigation per 3 days. Every treatment was irrigated with the same quantity of irrigation water (based on water requirements for one day), which gradually increased from December to June. A complete block design in three replicates was used. The area of the plot was 18 m2 (10m long x 1.8 m wide). The distance between plants alon~ the lateral irrigation line was 50-em. Transplanting was carried out at December 25 h and harvest began after (121) days from transplanting and extended for (67) days in both seasons. Before and after irrigation, soil moisture decreased with both depth and distance from the emitter. Moreover, it is noticed that, soil moisture content almost reached penn anent wilting point, 3.17%, particularly for the studied deeper soil depths, 20-30 em. and at a far distance from the emitter, 15-25 cm. The sequence of weighed average of soil moisture contents are B >A>D>C>E. We can recommended by using treatment (8) which gave the best results and should be avoided irrigated with treatment (El which gave the lowest results.
