Effect of different fertilizers on maize ( Zea mays L.)

الملخص

 Two filed experiments were carried out in a private Farm at KomHamda - Beheira, Governorate, Egypt during the two successive growing seasons of 2017 and 2018 to study the response of maize to nitrogen, organic and bio-fertilization on yield and quality of maize. The used experimental design was randomized complete block design (RCBD) with three replicates. The used maize hybrid (Single Cross 1100), thereafter, the seeds were surface sterilized with 1% sodium hypochlorite for 5 min, washed with sterilized water, and then treated with the microbial inoculants before planting. The treatments were nitrogen at three levels (50, 100, 150 kgN/fed), humic acid (5, 10, 15 kg/fed) and inoculation with mycorrihzae. The obtained results showed that inoculation with mycorrihzae mixed with 100 kgN/fed. gave the highest mean values of ear weight, ear length,number of row/ear and 100-grain weight, as compared with the other treatments. In addition, the treatment of humic acid at 15 kg/fed. plus 50kg/fed N recorded the maximum content of protein, carbohydrates and starch percentages, followed by mycorrihzae mixed with 150 kgN/fed., as compared with the other treatments, during both seasons under this study.
