Spike length, number of grains per spike and spike yield of Mexibac
.urpassed thoze of Giza 155.
On the contrary plant height and straw yield of Giz.a 155 exceeded
qiose of Mexibac. .
There was a progressive increase in plant height, spike length, numbvr
01 grains per spike, spike yield grain and straw yield by increasing the level
of nitrogen up to 40 kg. N/Feddan. .
The minimum grain and straw yield was obtained by the unfertilized
treatment and the maximum grain yield of Mexibac cultivar was obtained
5v 80 kg. N/Fed.
Maximum straw and grain yield of Giza 155 was obtained by adding 40
lcg. of N/Fed. .
The maximum plant height, grain and straw yield were obtained under
the fIfth irrigation system (L. e. by irrigation at the stage 01 three leal, 6
leaf and heading stage). On the contrary1 the minimum plant height, grain
ano straw yield were observed under the first irrigation System (i. e. by
irrigation of the stage of the three leaf only).
