Synergistic Effects Of Sodium Azide Mutagen And Nano – Potassium Fertilizer On Growth And Yield Traits Of Canola

The aims of this study were to evaluate the effect of three concentrations of sodium azide (SA) 0%, 0.02%, 0.04% under three levels of Nano-potassium (Nano-K) fertilizer including (0, 50, 100) ppm were added as foliar application after (25, 50, and 75) days after seedling, and their interactions on some of canola growth and yield traits such as plant height, leaf area, chlorophyll content, 1000-seeds weight, oil yield, and seed yield. All treatments were distributed as a factorial experiment using randomized complete block design (RCBD) with three replicates at P ≤ 0.05. The statistical analysis revealed that significant effects have been observed on all measured traits except chlorophyll content. Results showed that 0.04% of (SA) gave the highest plant height of (155.13) cm, leaf area of (3190.66) cm2, 1000-seed weight of (2.414) g, oil yield of (556.26) Kg/ha, and seed yield of (1167.9) Kg/ha compared to control treatments which recorded (145.08)cm, (2536)cm2, (2.353)g, (427.34)Kg/ha, and (938.4)Kg/ha respectively. Furthermore, 100 ppm of Nano-K fertilizer gave the highest plant height of (153.47) cm, leaf area of (3137.9)cm2, 1000-seed weight of (2.407)g, oil yield of (531.87) Kg/ha, and seed yield of (1185.7) Kg/ha in compared with the control treatments. The interaction between (0.04% SA + 100 ppm Nano-K fertilizer) was superior in most of the traits studied and recorded highest plant height of (157.58) cm, leaf area of (3515.9)cm2, 1000-seed weight of (2.450)g, oil yield of (589.77) Kg/ha, and seed yield of (1375.4) Kg/ha over than all treatments in addition to the control.
