Fertilization Of Some New Wheat Cultivars Grown Under Drought Conditions

In many developing countries, on-farm research is showing that, in specific instances, wheat yields can be doubied or even tripled by controlling weeds more effectivelly and by applying fertilizer and or other inputs (suri and singh, 1970,osipov 1977, harold, 1988).The objective of this investigation was to was to find out the most suitable rate of nitrogen fertilizers for growing wheat and maximizing wheat grain yield under rainfed conditions at the northern sinai using two wheat cultivvars, sakha 69 and sakha 92.
