Abstract
Greenhouse experiment were conducted during two successive seasons of
2000 and 2001 aiming to study the effect of different irrigation systems (drip and 20
em subsurface irrigation) and different water quantities (33 %, 66 % and 100) of field
capacity on growth, yield and quality of cucumber plant. Also soil humidity and
reflected radiation of plants.The results showed that, using drip irrigation system was
in favour for producing the highest plant height, number of leaves/plant, dry/fresh
weight ratio per plant, leaf area/plant, number of fruiVplant, shape index, total
yield/plant, dry/fresh weight ratio per fruit, soil humidity and average fruit weight. The
100 % of field capacity treatment gave the highest values for plant height, number of
leaves/plant, drylfresh weight ratio per plant, leaf area/plant, drylfresh weight
ratiolfruit and soil humidity. On the other hand the 66 % of field capacity treatment
gave the best results for number of fruit/plant, shape index, total yield and average
fruit weight. The interaction between irrigation systems and water quantitative
produced the highest values for number of leaves/plant, drylfresh weight ratio per
plant, leaf area/plant, drylfresh weight ratio/fruit and soil humidity by using drip
irrigation with 100 % of field capacity, however, the highest values for plant height,
number of fruit/plant, shape index, total yield/plant, average fruit weight and reflected
radiation of plant per all waves length were recorded after using drip irrigation with 66
% of field capacity treatment. Finally it is possibly suggested that drip irrigation with 100 % or 66 % of field capacity could be useful for enhancing growth, yield and reflected radiation of
cucumber under greenhouse condition in AI-Hassa Oasis KSA.
