With respect to the significance of finding methods, which may improve corn (Zea mays L.) yield and quality in the semi-arid areas of the world, an improved method and type of fertilization has been suggested and tested. A two-year field experiment (2016–2017) (split plot) was conducted in the Research Station of Safi-Abad, Dezful, Iran to test the effects of fertilization methods (soil application of fertilizer (N1), foliar application (N2), and fertigation (N3)) and micronutrient use (Fe and Zn at 3 gL⁻¹) on the yield and quality of corn plants. Cob (CH) and plant height (PH), weight of 1000 grains (W), corn yield (Y), weight of cob wood (CobWood), cob weight (CobW), number of rows in a cob (NR), number of grains in a row (NG), plant nutrient uptake of Fe and Zn, and grain protein (Pro) were determined. The single or combined effects of the experimental treatments significantly affected the measured parameters. The fertilization method significantly affected corn growth (CH), yield (W, Y, CobWood, and NR) and plant Fe uptake. However, micronutrients were significant on all the measured parameters except Pro. Although the soil method significantly increased plant uptake of Fe and Zn, the foliar application and fertigation methods significantly enhanced corn growth and yield. The combined use of the tested methods may enhance corn yield and quality in the arid and semi-arid areas of the world.

关于寻找可以提高世界半干旱地区玉米 ( Zea mays L.) 产量和质量的方法的重要性，已经提出并测试了改进的施肥方法和类型。在伊朗 Dezful 的 Safi-Abad 研究站进行了为期两年的田间试验（2016-2017）（裂区），以测试施肥方法（土壤施肥（N1）、叶面施肥（N2））的效果, 施肥 (N3)) 和微量营养素的使用（Fe 和 Zn 为 3 gL ^-1) 对玉米植株的产量和质量的影响。穗轴 (CH) 和株高 (PH)、千粒重 (W)、玉米产量 (Y)、穗轴木重量 (CobWood)、穗轴重量 (CobW)、穗轴行数 (NR)、数量测定了连续谷物的数量 (NG)、植物对 Fe 和 Zn 的营养吸收以及谷物蛋白质 (Pro)。实验处理的单一或组合效应显着影响了测量参数。施肥方法显着影响玉米生长 (CH)、产量 (W、Y、CobWood 和 NR) 和植物对铁的吸收。然而，除 Pro 外，微量营养素对所有测量参数均显着。虽然土壤法显着增加了植物对铁和锌的吸收，但叶面施肥和施肥方法显着提高了玉米的生长和产量。
