Effect of Pruning and Spraying of Ascorbic Acid on Growth, Fruits Yield and Quality and Some Physiological Attributes of Cucumber
This study was carried out during the two winter seasons of 2012-2013 and 2013-2014 to evaluate the effect of pruning and foliar application of ascorbic acid (AsA) on the growth, fruit quality and yield of cucumber cv. Fahd. The experiment included 4 treatments arranged in a split-plot design and replicated three times, where pruning treatments (pruning in the main stem and no pruning) were distributed randomly in the main plots, while the foliar application of AsA (using or without using AsA) were arranged in sub plots. The results indicated that plant height, leaf area, chlorophyll readings and fruit length were significantly increased in pruned cucumber plants than non-pruned plants. Otherwise, total yield was not affected significantly with pruning. Moreover, Spraying AsA on cucumber led to a positive significant influence on the plant height, early and total yield, fruit length and photosynthesis.
