Abstract

Background: Deficit irrigation is an optimum technique for producing products under drought stress conditions. The superabsorbent hydrogel is a hydrophilic polymer with cross-linked 3-D hydrophilic nets that are able to take up and keep noteworthy values of water and aquatic liquids. Recently published patents have provided significant information about the superabsorbent application in agriculture.

Objective: The aim of this study was to investigate the superabsorbent effect on the yield and some of the growth factors of Pisum sativum L. under drought stress conditions.

Methods: The experimental factors included: irrigation treatments at two levels of 100% and 75% water requirement by the plant. The second factor included the levels of superabsorbent application which included three levels of control treatment, potting soil with a weight percentage of 0.5 and 1. The third factor was the location of the superabsorbent application.

Results: According to the results, the largest root length value corresponded to I2S1U treatment plan, the largest root dry weight value corresponded to I1S2U treatment plan, the largest plant dry weight corresponded to I2S1U treatment plan, the largest grain dry weight corresponded to I2S1U treatment plan, the largest number of grains per pod corresponded to I2S2U treatment plan and the largest number of pods per plant corresponded to I2S1U treatment plan which were significant at 5% level.

Conclusion: It was concluded that the presence of the superabsorbent at the lower end of the pot was effective in providing water and nutrients for the plant root.

干旱胁迫条件下超级吸水剂对豌豆产量和某些生长因子影响的评估
背景:缺水灌溉是在干旱胁迫条件下生产产品的最佳技术。超吸水性水凝胶是一种具有交联三维亲水网的亲水性聚合物,能够吸收和保持值得注意的水和水生液体。最近公布的专利提供了有关超吸水剂在农业中应用的重要信息:本研究旨在探讨在干旱胁迫条件下超吸水剂对豌豆产量和一些生长因子的影响:实验因素包括:植物需水量为 100% 和 75% 的两种灌溉处理。第二个因素包括超吸收剂的施用水平,包括对照处理、重量百分比为 0.5 和 1 的盆栽土壤三个水平,第三个因素是超吸收剂的施用位置:结果:I2S1U 处理方案对应的根长值最大,I1S2U 处理方案对应的根干重值最大,I2S1U 处理方案对应的植株干重最大,I2S1U 处理方案对应的谷粒干重最大,I2S2U 处理方案对应的每荚谷粒数最多,I2S1U 处理方案对应的每株荚果数最多,均在 5%的水平上显著:结论:在花盆下端使用超级吸水剂能有效地为植物根部提供水分和养分。
