Abstract

Abstract Corn is one of the most important cereal crop grown in Iran. A complete randomized design with four replications was used to analysis the influence of soil amendment of super absorbent polymer on grain yield and yield components of corn in center of Iran in 2016 and 2017. Treatments with super absorbent polymer were 0 kg/ha (S1), 15 kg/ha (S2), 30 kg/ha (S3), and treatments with fertilizers were 50% (F1), 75% (F2), 100% (F3), which could be combined into nine pots. The influence of super absorbent polymer was significant on spike weight in 2017, above-ground biomass in 2016, one hundred seed weight in 2016, and grain yield in 2017. There was no meaningful influence of super absorbent polymer on spike weight in 2016, above-ground biomass in 2017, 100 seed weight in 2017 and grain yield in 2016. Fertilizer treatments had significant influence on spike weight, above-ground biomass, 100 seed weight, and grain yield in both 2016 and 2017. The interaction between SAP and fertilizers had significant effect on above ground biomass in 2017. In both years, the highest spike weight, above ground biomass, 100 seed weight and grain yield was related to S3 (30 kg/ha), followed by S2 (15 kg/ha) and S1 (0 kg/ha), respectively. 100% application of fertilizer (F3) had obtained the maximum spike weight, above ground biomass, 100 seed weight and grain in both 2016 and 2017. Our data have shown that the applied SAP had a remarkable effect on corn growth and yield under different fertilization treatments, and its application of 30 kg/ha gave the best corn production index.

高吸水性聚合物土壤改良剂对伊朗中部地区玉米产量及产量组成的影响

玉米是伊朗最重要的谷类作物之一。采用4个重复的完全随机设计，分析了高吸水聚合物土壤改良剂对2016年和2017年伊朗中部地区玉米产量及产量构成因素的影响。高吸水性聚合物处理分别为0 kg/ha (S1)、15 kg/ha (S2)、30 kg/ha (S3)，化肥处理分别为50% (F1)、75% (F2)、100% (F3)，可组合成9盆。高吸水聚合物对2017年穗重、2016年地上生物量、2016年百粒重和2017年籽粒产量的影响显著。高吸水聚合物对2016年穗重、2017年地上生物量、2017年百粒重和2016年籽粒产量均无显著影响。施肥处理对2016年和2017年小麦穗重、地上生物量、百粒重和籽粒产量均有显著影响。2017年，SAP与肥料互作对地上生物量有显著影响。2年最高穗重、地上生物量、百粒重和籽粒产量分别与S3 (30 kg/ha)、S2 (15 kg/ha)和S1 (0 kg/ha)有关。100%施肥(F3)在2016年和2017年均获得最大穗重、地上生物量、百粒重和粒数。结果表明，不同施肥处理下，施SAP对玉米生长和产量均有显著影响，其中施30 kg/ha玉米生产指标最佳。
