This research was conducted to determine the most responsive phenological
stage for supplementary irrigation of the durum wheat in a primary stationary
region.
It consisted of six different water treatments in addition to control (non
irrigated)
:
1-From planting to seedling emergence; 2-From planting to tillering; 3-From
planting to booting; 4-From planting to flowering; 5-From planting to the end of
the milk stage; 6–Sowing irrigation and irrigation according to necessity
throughout the milk stage.
The study has been repeated in four blocks for three seasons from 2002 to
2005. The results of the first two seasons showed that the:
The treatment from planting to booting, was canceled because of the rain and
soil dampness during this growth period. A significant increase in production,
water use efficiency, and one 1000 kernel weight, of both 5th and 6th treatments was
noticed in comparison with other treatments and the control. Results of the three
seasons were varied due to the environmental variation in temperature and amount
of rainfall.
A study conducted at Marj Al Kareem (The Scientific Agricultural Centre
for Researches) in cooperation with Damascus University Faculty of
Agriculture, The target group was Awassi sheep; about 323 ewes, 30 rams of
the age "3-4 years", 424 lambs fo
rm the age 1 day to 5 months during the
season 2002-2003. The animals have been put under the same nutritional and
environmental conditions, and the same health care program.
The Experiment was conducted during the successive growing
seasons (2013/2014- 2014/2015) where half–diallel hybridization was
conducted between eight genotypes of bread wheat.
