The impact of different nutritional treatments on maize hybrids morphological traits based on stability statistical methods

Abstract

This study investigates the sustainability of agriculture in the context of the various debates that have occurred about agriculture, its elements, and functions. One of the main breeding programs aims to achieve stable and high yield varieties in different conditions by studying the effect of genotypes on traits year on year. The study investigates the effect of genotypes on grain yield traits in two hybrids (FAO340 and FAO410) planted in a completely randomized block design with four replications for two years in the Debrecen region of Hungary. It includes a combined variance analysis significant on different fertilizer treatments with traits on FAO410 and FAO340 hybrids. The AMMI analysis and biplot showed that one thousand grain weight and leaf number were the maximum effects on the yield in the FAO340 hybrid. Also, plant fresh weight and plant height were the maximum effects on the yield in the FAO410 hybrid. The fourth fertilizer treatment had the highest yield, with desirable stability on FAO340 and FAO410. There were desirable stability, maximum effect on yield by plant fresh weight, seeds per column amount, and stem diameter effects for the FAO340 hybrid, and seeds per ear weight, number of seeds per column, ear weight, and number of nodes effects in the FAO410 hybrid by GGE biplot analysis. The results confirmed that both the FAO340 hybrid and the FAO410 hybrid had desirable stability in Hungary.
