The field experiment was carried out during the two successive winter seasons 2008/2009 and 2009/2010 in private sector farm at Kafr Elsohbi village, Kalubia governorate, to investigate the effect of soil addition of Humic acid, Rootmost or Softguard as well as the foliar spray with Amino power, Caboron or Chitosan on growth, chemical composition, yield and quality of strawberry cv. Festival. Obtained results showed that the soil addition of Rootmost at 2ml/l three times to strawberry plants combined with spraying the plants with Amino power at 0.5ml/l ten times during the growing season are recommended to increase the vegetative growth, early as well as total produced yield. Moreover, Rootmost at 2ml/l combined with Caboron at 1ml/l are recommended to obtain the highest exportable yield with best quality(T.S.S, vitamin C, total acidity, reducing and total sugars as well as anthocyanin). |
