Response of several genotypes of bread wheat Triticum aestivum L. to levels of silica fertilizer

Abstract EN

A field experiment was carried out at the Agricultural Research and Experiment Station in the Sayada area of the College of Agriculture at the University of Kirkuk for the winter season 2021/2022 by randomizing complete block design with a split-plot system with 30 experimental units per block to stndy the effect of spraying three levels of silica fertilizer (0, 2, and 4) ml.1¹ and ten wheat genotypes which are (Wafia, Al-Fayadh, Abu Ghraib 3, Baghdad, Jihan 99, Adana, Sham 6, Bora, Al-Rashid, and Monnellsa).

The results showed that there were significant differences between the levels of silica fertilizer in all the studied traits, where (4 ml.1¹) of silica with Sham6 was superior in the traits of the biological yield (19.79 ton.ha ¹), the interaction was significant for all the studied traits, where the genotype was superior in relation to the interaction levels of spraying with silica fertilizer of (0 ml.1¹) silica with the genotype (Baghdad1) was superior in the number of effective tillers (514.67 m2) The number of spikes (454.10 spikes.m2) and the protein percentage (16.35) also exceeded the concentration of (4 ml.1¹) silica with the genotype (Baghdad1) in the weight of 1000 grains (48.86).
