Abstract
A field experiment was carried out in Al-Mijar Al-Kabeer District, 25 km South of Misan Governorate, Iraq, during 2016/17 and 2017/18 seasons to study effect of spraying with Azolla extract at 0, 20, 40 and 60% and NPK-fertilizers levels (60, 80 and 100% of the recommended doses "RD") on Egyptian wheat Sids 1cultivar productivity under new reclaimed soils. The experiment was applied according to split-plot design with three replicates.The results showed that increasing concentration of the Azolla extract resulted in an increase in most studied characters in both seasons. The increasing rate in grain yield was 57.37 and 51.71 % and in biological yield was 37.66 and 21.57 % for foliar spraying with Azolla extract at 60 % compared with control treatment in the first and second seasons, respectively. Most studied characters gradually increased due to increasing NPK-fertilizers levels from 60 to 80 and 100% of RD and without significant differences between 80 and 100% in both seasons. As for the interaction between spraying with Azolla extract levels and NPK-fertilizers levels, it was significant on spike length in 1st season only, number of spikes/m2, weight of 1000 grains and biological yield in both seasons. It can be stated that foliar spraying Egyptian bread wheat Sids 1cultivar with Azolla extract at 60 % alongside mineral fertilizing with 152.0 kg N + 42.8 kg P2O5 + 45.6 K2O ha-1 (80% of RD) to preserve high productivity simultaneously reduce production costs and environmental pollution under the environmental conditions of Misan, Iraq.
