أجريت الدراسة على كرم شجيراته بعمر 17 سنة عند بدء الدراسة مزروع بصنفين (حلواني، بيتموني). و درست معاملتان للري الناقص (80%, 60%) إضافة للشاهد (ري كامل) بمعدل ثلاثة مكررات للمعاملة, و طبقت تقنية الري بالتنقيط (خط ري لكل صف شجيرات و ثمان نقاطات لكل شجيرة), و قورن تأثير المعاملات المائية في كمية الإنتاج و نسبة السكر في الثمار.
This study was carried out on a 17 years Vineyard (Helwani,
Betamooni. Cvs) when the study started. Two deficit irrigation
treatments were studied (%88, 60%), in addition to the control (full irrigation), and each treatment included three replications. Drip irrigation technique was applied (one irrigation line for each tree line, and eight drippers for each tree). Fruit yield and sugar
percentage were observed under different water treatments.
