| Abstract | ||
| The present study was conducted at the experimental area of Horticulture research station at El-Kanater El-Khayria, Qalyubia Governorate, Egypt, during the two seasons 2019 and 2020), aiming to determine the best growth characters for three species of timber trees viz. Populus nigra, Paulownia hybrid T121 and Cedrela odorata irrigated under three water depletion rates 30, 45 and 60 % of the available water. The obtained results from the combined analysis of two seasons illustrate that Paulownia hybrid T121 achieved the highest significant increment of seedling height, stem diameter followed by Populus nigra meanwhile Cedrela odorata was the least. On the other hand, Populus nigra gave significantly the longest root length and Cedrela odorata was the intermediate, whilst Paulownia hybrid T121 deduced the shortest one irrespective the effect of available soil moisture depletion (ASMD). It can be concluded that irrigating the different seedlings of the three species significantly affected where water depletion and showed that irrigation at 60 % depilation resulted in root length exceeded whereas increment of height growth, stem diameter, biomass fresh and dry weights diminished. | ||
