Abstract
Ashraf Saad Gouda . Impact of Irrigation Water management
and Silicon Spraying on Avoiding Cold Injury Improvement
yield of Some Mongo Cvs. . Unpublished M.Sc. Thesis,
Department of Horticulture, Faculty of Agriculture, Ain
Shams University, 2018.
The present study was carried out during 2015 and 2016 seasons
on Kitt and Seddik mongo trees to evaluate the effect of three
irrigation water management (4000 m3 of irrigation water were
applied to the four physiological stages of mango tree growth as 15
& 20 & 40 & 25 % , 30 & 15 & 35& 20 % and 35 & 20 & 30& 15
% m3 / tree/ year, respectively) as well as four concentrations of
potassium silicate on avoiding cold injury and improvement yield
of Kitt and Seddik mongo trees.
Irrigation Mango tree by the second program water management
(30 , 15 , 35 , 20) recorded The highest values of vegetative growth
in terms of number of shoot /tree and lower values of leaves
percentage affected with cold injury, Also, an evident increase in
the content leaves of N & K elements , C/N ratio and final fruit set
% total yield by divided irrigation water at the four physiological
stages of mango trees (30 , 15 , 35 , 20) was recorded compared
with the other two water managements. No significant differences
between the second and third irrigation water management
programs (30% , 15% , 35% , 20% and 35% , 20% , 30% , 15%)
on values of leaf area, P% and total carbohydrates as well as on
TSS, acidity and L-ascorbic acid content of fruits .
Spraying trees with potassium silicate in three times during the
period from October to January at the rate of 1000 ppm give the
highest values of quality characteristics at mango trees and their
fruits. While sprayed with potassium silicate at 2000 ppm achieve
moderate values of the mentioned characteristics
It could be recommended from the obtained data that irrigation
water management at the four physiological stages (30 , 15 , 35 , 20)
of Kitt and Seddik mongo trees and spraying 1000 ppm potassium
silicate in dormancy period is considered a good treatment to avoid
cold damage on leaves and fruits as well as in giving the highest
yield and quality of mango fruit
