Abstract
Pot experiments were conducted during the summer season of 1990 to study the effect of phosphorus and some micronutrients applied by two different methods on growth and chemical constituents of maize variety Giza 2. Treatments comprised all possible combinations of 3 rates of soil applied phosphorus ; 0, 30 and 60 kg P205 / fed; zinc and manganese were applied using two methods: foliar at the rate of 90 ppm, and to the soil at the rate of 5 ppm. Phosphorus significantly increased dry matter yield of maize plants , and the rate 30 kg P205/fed showed the highest dry matter yield. Zinc applied to the soil showed the highest dry matter yield followed by Mn applied to foliage. A significant positive correlation coefficient between dry weights of the 4th and 5th leaves and dry weights of young leaves, stems and whole plants were evident . A significant positive correlation was obtained between Zn con-centration and dry weight.A significant negative correlation was obtained between P percentage/ Mn concentration in young leaves.
