“…The uptake of nutrient (N/ P/ K) and grain yield both were significantly ( p ≤ 0.05) affected by varied NPK levels and/or nutrient omission. Increasing doses of NPK up to 125% of RDF significantly ( p ≤ 0.05) increased the uptake of these macronutrients in maize grain, which is also supported by the results of other maize research [39]. Application of 125% RDF might have caused higher nutrient concentration in maize grain, and for the same reason, unlike for the higher doses of NPK (150% RDF), the dilution effect of nutrients was not witnessed in grain [40].…”

In the present two-year study, an attempt was made to estimate the grain yield, grain nutrient uptake, and oil quality of three commonly grown maize ( Zea mays L.) hybrids fertilized with varied levels of nitrogen (N), phosphorus (P) and potassium (K). Results obtained from both the experimental years indicated that application of 125% of recommended dose of fertilizer (RDF) recorded maximum grain yield (10.37 t ha -1 ; 124% higher than control). When compared with 100% RDF, grain yield reduction with nutrient omission was 44% for N omission, 17% for P omission, and 27% for K omission. Nitrogen uptake was increased with increasing NPK levels up to 150% RDF that was statistically at par ( p ≥ 0.01) with 125% RDF. Increasing trend in P and K uptake was observed with successive increase in NPK levels up to 125% RDF, above which it declined. The protein content was significantly higher in grains of var. P 3396 with 125% RDF. Nutrient management has significant ( p ≤ 0.01) role in the grain oil content. Saturated fatty acids (palmitic, stearic and arachidic acid) content decreased, and unsaturated fatty acid (oleic, linoleic and linolenic acid) increased with increasing NPK levels. The average oleic acid desaturation and linoleic acid desaturation ratios were increased with increasing NPK levels up to 100 and 125% RDF, respectively. However, average monounsaturated fatty acids (MUFA): poly-unsaturated fatty acids (PUFA), saturated: unsaturated as well as linoleic: linolenic acid ratios were increased on receiving 75% RDF, and beyond that it showed decreasing trend. The omission of K had the highest inhibitory effect on corn oil quality followed by N and P omission.

“…These are heights that, due to various biotic and abiotic factors to which the maize plants are exposed, they do not usually reach [ 36 , 63 , 64 ]. In addition, the fertilizer dose, the genotype used and the harvest year are other factors that influence the adequate use of N, P and K fertilizer by maize plants [ 65 ].…”

“…The low ash, fat and protein contents in the chemical composition of corn starches, reported under the different fertilization schemes, indicate their high purity. In the literature, fertilization with N is reported as the main factor that determines the final concentration of grain protein [ 12 , 65 , 76 ]. In this sense, across all the treatments, a significant effect was found for treatments T7 and T3, which included chemical fertilizer, bioinoculants and/or organic matter within their formulation ( Table 1 ).…”

Globally, corn is the most economically important crop, surpassing other cereals of economic importance. However, the tillage methods, monoculture and the abuse of synthetic agrochemicals used in Mexico have led to the loss of fertility and soil yield. In this sense, the application of alternative fertilization methods based on chemical fertilizer, organic matter and biofertilizer, applied alone or in combination, can stimulate the defense systems of corn plants and increase their yield. Therefore, in this research, some fertilization schemes were tested on purple corn plants of the Kculli race through the evaluation of some growth and yield variables, as well as the subsequent evaluation of the chemical characteristics of the corn grain produced in each fertilization scheme. The results indicate highly significant differences (p ≤ 0.05) between treatments, for the different growth and yield variables studied. Of all the fertilization schemes evaluated, treatment T7 obtained the best grain yield of 6.19 ± 0.07 t ha−1, with respect to treatment T1 of 1.02 ± 0.01 t ha−1, as well as the highest protein content and starch quality. Being clear the positive effect of the adequate contribution of the macro and micronutrients used exerts on the corn crop in each of the fertilization schemes studied. On the other hand, the analysis carried out on the grains was found within the values reported by other authors.

“…Mineral fertilizers cause an increase in production costs (Novais et al 2007). Generally, the research results indicated that different maize hybrids have a diverse yield compared with nitrogen fertilizer levels, and the Armagnac hybrid can be the maximum grain yield (Széles et al 2019;Pepó and Karancsi 2017). Superior hybrid recognition in the breeding plan is always difficult due to treatment changes in the target areas and the interaction of these changes with the genotypes studied.…”

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.
