Abstract
Two field experiments were conducted at a private field in Dekernis Center, Dakahlia Governorate, Egypt, during the two successive winter seasons of 2014/2015 and 2015/2016. The objective of these experiments was to study the effect of foliar and mineral fertilization treatments on growth, yield and its attributes and grain quality of bread wheat Misr 1 cultivar. Regarding the effect of foliar application treatments i.e. without foliar spraying (control treatment), spraying with commercial fertilizer Fert-plus powder (20-20-20) as a source of NPK at the rate of 4 g/ liter, solution of micro-elements (Zn, Mn and Fe) in the form of Zn-EDTA, Mn-EDTA and Fe-EDTA and at the rate of 3 g of each/liter water, amino acids in the form of Amino-Cat at the rate of 5 ml Amino-Cat/liter water, yeast extract (YE) at the rate of 100 ml/Liter and the mixture of NPK, Micro (Zn, Mn and Fe), amino acids and yeast extract at the rates of 4 + 3 + 5 + 100/liter water, respectively in each spraying on growth characters i.e. number of days to 50% heading (days), total chlorophylls content in flag leaf (SPAD), flag leaf area (cm2) and plant height (cm), yield and its components i.e. number of spikes/m2, number of spikelets/spike, number of grains/spike, grains weight/spike (g), 1000-grain weight (g), gGrain yield (ardab/fed) and straw yield (heml/fed) and grains quality characters (crude protein and potassium percentages in grains, it was significant in the two growing seasons.With reference to the effect of NPK fertilization levels on growth characters i.e. number of days to 50% heading (days), total chlorophylls content in flag leaf (SPAD), flag leaf area (cm2) and plant height (cm), yield and its components i.e. number of spikes/m2, number of spikelets/spike, number of grains/spike, grains weight/spike (g), 1000-grain weight (g), grain yield (ardab/fed) and straw yield (heml/fed) and grains quality characters (crude protein and potassium percentages in grains, it is apparent from obtained results indicated that each increase in NPK fertilization levels was accompanied with significant increase in all studied characters, with exception number of days to 50% heading (days) in both seasons.Results indicated that there was a significant effect due to the interaction between both studied factors (foliar application treatments and NPK fertilization levels) on flag leaf area, spike length, 1000 – grain weight and potassium percentage in grains (in the second season) and chlorophyll content in flag leaf, plant height, number of spikes/m2, number of spikelets/spike, number of grains/spike, grains weight/spike, grain and straw yields per feddan and crude protein percentage in grains (in both seasons).It can be concluded that foliar spraying wheat Misr 1 cultivar twice after 35 and 50 days from sowing with the mixture of NPK, Micro (Zn, Mn and Fe), amino acids and yeast extract beside mineral fertilizing with 64.0 kg N + 36.0 kg P2O5 + 38.4 K2O/fed in order to maintain high productivity and grains quality at the same time reduce production costs and environmental pollution under the environmental conditions of Dekernis Center, Dakahlia Governorate, Egypt.
