Abstract
 
Present study was conducted during two winter seasons of 2017/2018 and 2018/2019 in farm (Ghazala Village), Faculty of Agriculture, Zagazig University, to evaluate the impact of seven fertilization treatments i.e. F1: humic acid (4 kg/fad), F2: F1 +50%  recommended dose of nitrogen (37.5 kg N/fad), F3: commercial organic-fertilizer (3G-101), F4: F3+50% recommended dose of nitrogen (37.5 kg N/fad ), F5: yeast extract, F6: F5+ 50%  recommended dose of nitrogen(37.5kg N/fad ) and F7: 75kgN/fad (recommended dose), on productivity of two  wheat cultivars i.e. Shandawel-1 and Misr 2. Results alluded that Shendawel-1 cultivar surpassed Misr2 cv in each of chlorophyll content (SPAD unit), ​​flag leaf area (cm2), spike length (cm), number of spikelets and grains/spike, 1000 grain weight (g), spike weight, number of spikes/m2, biological, straw and grain yields as well as harvest index (HI). Treatment F2 outperformed others in chlorophyll content. Treatment F6 recorded the highest value in each of: flag leaf area, plant height, spike length, number of spikelets and grains/spike, 1000 grain weight, number of spikes/m2, biological, straw and grain yields/fad and protein content. Treatment F1 gave the lowest values for the previous traits, but give higher harvest index compared to treatment F5. Grain yield/fad positively and significantly correlated with plant height, spike length, No. of spikletes/spike, 1000 grain weight, spike weight and number of spikes/m2.
