Economical Productivity of Maize Genotypes under Different Herbicides Application in Two Contrasting Climatic Conditions

Maize ranks first among worldwide production and an important source of human animal feed. Its can be affected by management practices climatic conditions. The objective this study was to estimate stability yield hundred grains weight six maize genotypes during two growing seasons at locations, subjected four different treatments: T1 treatment—without herbicide, Control; T2 treatment—active substance Nicosulfuron Motivell commercial preparation; T3 Rimsulfuron Tarot; and, T4 Forasulfuron Equip. Additive main effects multiplicative interaction—AMMI model genotype × environment interaction—GGE biplot were used GEI—genotype interaction. results showed that the influence (G), year (Y), locality (L), treatment (T) all interaction on significant. share in total phenotypic variance 64.70%, while 26.88%. IPCA1 terms G T 50.6%, IPCA2 44.74%, which comprised together 94.80% axis high interaction, indicates out significance variation level a significant effect. Genotype L-6 had same mass 100 (37.96 g) both years testing, L-1, with 4.46 g, largest difference between years. This clearly but also stress under sulfonylureas environmental factors. highest values weight, L-5 L-6, expressed grain (4665 kg ha?1 4445 ha?1).
