Response of some Bread Wheat Cultivars to Foliar Feeding Stages with Nano-Microelements

Abstract

During the growing season, a field experiment was conducted in one of the fields in the Um Al-Akf region (about 5 kilometers from the heart of Al-Muthanna Governorate) at 45.23 longitudes and 31.32 latitudes (2021-2022). Three cultivars were produced for the first time in Al-Muthanna governorate, and they were compared to the approved variety in the governorate, Ibaa 99, to determine the impact of spraying micro-Nano fertilizers at different stages had on the growth characteristics of the four wheat varieties. For the most crucial phase, represented by the cultivars (Abu Ragheef, Baghdad, Babel, Ibaa 99), maximum utilization of the micro-nano components is attained. Stages of spraying micro-nano fertilizers were (tillering stage, booting stage, flowering stage). A split-plot design with a randomized complete block (RCBD) and three replications was used for the experiment. In the primary plot, we grew four different wheat varieties, while in the secondary plot, we sprayed different concentrations of micro- and nano-element fertilizer at different times. GenStat was used to compare the mean coefficients with the L.S.D. at a significance level of 0.05. Statistical analysis revealed that the Abu Ragheef cultivar was the best in terms of plant height (104.10 cm) and spike length (16.722 cm), while the Babylon cultivar gave the highest leaf area with an average of 56.32 cm2 without significantly different from the Abu Ragheef cultivar that gave an average of 55.02 cm2, additionally, the Babylon cultivar had the highest average for the characteristic of chlorophyll content of leaf to 49.54 micrograms cm−3, without significantly different from the (22.864 t ha−1). In terms of leaf area (53.41 cm2), grain output (7.406 t ha−1), and biological yield, the booting stage was the most successful of the spraying nano-micro fertilizer stages (22.481 t ha−1).
