Abstract

In order to study the influence of the growth regulator Biozyme TF (foliar applications at three levels: 0, 1.5, and 3 mg L-1, at the physiological stage V3/V4, and then after 15 days) on some growth traits, yield and its components of five rice genotypes ((Anber 6, Anber 33, Pokkali, genotype 13, genotype 14) and some chemical properties, a field experiment was conducted with a RCBD with three replicates in a farmer's farm in Najaf Governorate during the 2024 agricultural season. The results showed that spraying with Biozyme growth regulator led to a clear increase in all studied vegetative growth traits in all genotypes, as the B2 spray treatment outperformed and recorded the highest average of leaf area, panicle length and dry weight, which amounted to 65.00 cm2, 17.832 and 79.00 respectively, compared to the control treatment B0, which recorded the lowest averages. Treatment B2 gave the highest average leaf content of Mg, Cu, Fe and Zn, reaching 243.451, 5.8378, 263.852 and 10.4206, respectively, while the control treatment T0 gave the lowest average for the mentioned traits. Genotype Anber 33 also outperformed other genotypes in the leaf content of copper (6.3911), zinc (10.6456), and iron 326.470.
