Abstract

The present investigation was carried out at Tamiea Agric. Res.
Station, Fayoum Governorate during 2009 and 2010 seasons to study
the effects ofammonia fertilizer levels, i.e. N1: 15, N2:30 and N3:45
and N4: 60 kg N fed-1,four irrigation regime i.e. irrigation at I1: 0.6,
I2: 0.8, I3: 1.0 and I4: 1.2cumulative pan evaporation (C.P.E.) and
their interaction on yield, yield components and some crop water
relations of sunflower (Sakha 53). The strip- plot design with four
replicates was used. The obtained results were as follow:
Yield and all yield components i.e. plant height, head diameter
and weight, as well as seed weight head-1and 100- seed weight, were
obtained from applying 60 kg N fed-1and irrigating sunflower at 1.2
C.P.E., surpassed significantly those obtained from the other
treatments. However, the highest seed oil content were detected
fromapplying 15 kg N fed-1 and irrigating sunflower at 1.2C.P.E.
Seasonal water evapotranspiration (ETC) reached its maximum
values (54.69 and 53.05 cm in 2009 and 2010 seasons, respectively),
as sunflower crop received60 kg N fed-1 and irrigated at 1.2C.P.E..
The daily ETc increased by increasing the irrigationintervals from
0.6 to 0.8 to 1.0 to1.2 C.P.E.. The peak of daily ETc occurred on
July. The KC (crop coefficient) during the growing seasons were
0.42, 0.52, 0.62,0.88 and 0.51 for May, June, July, August and
September months, respectively, (means of two seasons).
Applying 60 kg N fed-1and irrigation at 1.2C.P.E. gave the
highest water use efficiency, i.e. 0.497 and 0.480 kg seeds m-3 water
consumed in 2009 and 2010 seasons, respectively.
