Effect of different irrigation methods and rates on growth of Cycas revoluta, thunb seedlings [electronic resource].

Includes references.

The present work was designed to study the effect of different rates of irrigation(300 , 450 , 600 and 750 ml per plant) and two irrigation methods (drip or manual irrigation) on growth of Cyeas revoluta seedlings during two seasons ( 2006 and 2007)in the green-house at Antoniades Branch, Hart. Res. Insl., ARC. Alexandria., Egypt. The results indicated that different irrigation rates had little effect on some plant characters of Cycas seedlings (number of leaves I plant. leaf length, number of leanetI leaf, stem circumference and total chlorophylls content). While, the other characters revealed negligible affects in this concern. However, the high and medium rates of water 750 and 600 ml, plant recorded the same results by using the rate of 450 mi. plant while, the lowest rate (300 ml) of water gave the lowest values of all plant trials were stUdied. So, it could be concluded that the present stUdy revealed great economic value in terms of rational use of water for irrigation.
