Abstract
In order to investigate the effect of biofertilizers application on agronomic characteristics and yield of corn cultivars this study was conductedin Borujerd region of Lorestan Province in 2023. This experiment was done factorially based on a completely randomized block design with three replications. The experimental factors included three fertilizer application levels (control, humax, nitroxin and humax + nitroxin) and corn cultivars (KSC400, KSC201 and KSC410). The results showed that the effect of fertilizer and cultivars on plant height, ear height from the soil surface, leaf length, stem diameter, ear length, number of seed rows in an ear, number of seeds in an ear row, number of seeds in an ear, 100 grain weight, seed yield, dry matter yield and harvest index were significant. The interaction effect of treatments wassignificant on the plant height, ear height from the soil surface, number of seeds in a row of ears, number of seeds in an ear, weight of , 100 grain weight, seed yield and dry matter yield. KSC410 was the better cultivar and the highest growth rate and grain yield components belonged to this cultivar. The integrated application of humax and nitroxin fertilizer had the highest efficiency in increasing the growth and yield. KSC410 cultivar with the integrated application of nitroxin and humax had themaximum values of plant height (231 cm), cob height from the soil surface (111 cm), and seed numbers per cob (601). The highest hundred grain weight, grain yield and biological yieldobtained from the mentioned treatments. these values were 34 g, 9216 and 30256 kg ha-1, respectively. Based on the results of this study, in order to achieve the highest corn yield in Borujerd region of Lorestan Province, KSC410 can be used with the integrated application of nitroxin and humax fertilizer.
