Evaluation of growth indices, yield and quality of Simon grain corn under the influence of biological, organic and chemical fertilizers to achieve healthy food production

These days, the application of organic and biological fertilizers to optimize the use of chemical fertilizers as well as improve crop quality and maintain soil fertility in sustainable agricultural systems, has gained special significance. A split-split-plot experiment was carried out in a randomized complete block design with 4 replications and two consecutive years in 2018-19, to investigate the effect of combined application of biological, organic, and chemical fertilizers on yield and quality of single-cross Simon corn grain. Nitrogen treatment was used in three levels of zero, 150 and 300 kg/ha or by using 46% urea fertilizer and vermicompost treatment was used in three levels of 0, 6 and 12 tons per hectare and mycorrhiza treatment was considered in two levels of application and non-application. The study of growth logistics indices showed that Muse V12ton/hecN300kg/hec it has been superior to other levels in terms of indicators TDM, LAI and NAR. The results showed that, in the interaction effect of mycorrhiza × vermicompost 6 tons × 150 kg N, grain yield of 14.36 t / ha and grain nitrate accumulation reached 46.62 mg/kg grain weight which is the most desirable fertilizer composition based on the purpose of the research.
