ABSTRACT. Two field experiments were conducted at Hada Al-Sham Experimental
Station of King Abdulaziz University, to study the effect of
three different rates of irrigation, based on depletion ratios of 50%,
25%, 10% (IR1, IR2, IR3) and four different rates of nitrogen fertilization
(urea), zero, 100, 200, 300 kg/ha (N0 , N1, N2, N3) during two successive
seasons (autumn 1994 and spring 1995) on total dry matter
yield and its components (ear and straw), and nitrogen uptake of hybrid
maize plant (AGA 215 cultivar). The purpose was also to detect changes
in the chemical properties of the soil as influenced by these parameters.
The irrigation scheduling processes were designed by applying
water of 90.15 cm/autumn (9015 m3/ha/autumn season) and
82.1 cm/spring (8210 m3/ha/spring season), respectively, where the irrigation
frequency was changed. There was a highly significant difference
between seasons as regard dry matter production, with the first
season (autumn) gave higher weight of straw, ear, total yield of dry
matter, and nitrogen uptake than the second season (spring). Irrigation
treatments significantly affected yield traits. The irrigation treatment
IR3 had higher values for dry weight of ears, and total yield of dry matter.
Also, nitrogen treatments significantly affected some plant yield
variables; where treatment number N3 gave higher values of weight of
straw, total yield of dry matter and nitrogen uptake. The season affected
significantly the potassium and organic matter content in soil. Irrigation
levels affected significantly only the soil potassium (K). Meanwhile the
applied nitrogen rates affected significantly soil pH , nitrogen (N) and
potassium (K) soil content. The reported results can be used as a guideline
for the investigators in the field of maize irrigation and similar
field crops. |
