Abstract

In order to evaluate productivity of some wheat cultivars grown in sandy, saline soil under foliar spraying with humic acid, amino acids and nitrogen fertilizer levels. Highest chlorophyll b and carotenoid content, percentage of sodium and calcium, tallest plants and higher number of tillers/plant were achieved from Gemiza 9 cultivar. The highest relative growth rate (RGR) and net assimilation rate (NAR), chlorophyll and total chlorophyll values, higher flag leaf area and stem diameter were resulted from Giza 168 cultivar. While, higher percentages of proline, total phenols and potassium percentages were found from Shaka 93 cultivar. The earlier for a number of days to heading and flowering were resulted from Shaka 93 cultivar. Application of humic and amino acid mixture significantly enhanced total leaf area/plant, plant dry weight after 75 and 95 days from sowing (DFS), RGR, NAR, photosynthetic pigments, i.e. chlorophyll a, chlorophyll b and carotenoids and proline contents. In addition, highest total phenols, potassium and calcium percentages, height flag leaf area, tallest plants, highest stem diameter and number of tillers/plant compared with other foliar spraying treatments. Accordingly, it could be recommended that foliar spraying wheat plants Giza 168 cultivar with the mixture of humic acid and Amino acids with addition, mineral fertilizing with 262 kg N/ha to obtain the best growth characters of wheat under newly reclaimed sandy saline soil conditions.
