| Abstract | ||
| Two field experiments in the form of strip- plot design with four replications were conducted at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, Dakahlia Governorate, Egypt during 2016/2017 and 2017/2018 growing seasons. The aim of study was to determine the response of wheat cv. Gemmiza 11 to different nitrogen fertilizer levels (40, 50, 60 and 70 kgN/fed) and foliar spraying with alga as extract biofertilizer (1, 2, 3 g/L and without spraying). Data indicate that significant differences among nitrogen fertilization levels and foliar concentrations with alga extract for all studied characters in the two seasons. It can be summarized that fertilizing wheat with 70 kg N/fed as well as spraying with alga extract as biofertilizer at 3 g/L to give the highest averages of number of days to heading, plant height , spike length , number of spikes/m2, number of grains/spike, 1000- grain weight, biological yield and harvest index and also scored maximal values for grain yield (24.15 and 22.78 ardab/fed) and (24.22 and 23.15 ardab/fed), respectively for both seasons. More, the interaction effect show significant differences on plant height and biological yield in both seasons and spike length in the 2nd season only.From the obtained results in this study ,it can be concluded that planting wheat ,Cv Gemmiza 11 and mineral fertilizing with 70 KgN\fed and twice foliar spraying with alga extract at the rate of 3g\L to maximize wheat productivity under the environmental conditions of EL Mansoura, Dakahlia Governorate, Egypt. | ||
