The growth and productivity of wheat crops depend on the availability of essential nutrients such as zinc (Zn) and potassium (KO), which play critical roles in the plant's physiological and biochemical processes. This study aimed to investigate the synergizing effect of zinc and potassium fertilizers on uptake of both the nutrients, growth, yield, and quality of the Hashim-08 cultivar and local landrace, during the 2019-2020 growing season in Dera Ismail Khan, Pakistan. The experiment was designed using a split plot pattern in a randomized complete pattern, with main plots for the wheat cultivars and subplots for the fertilizer treatments. Results indicated that both cultivars responded positively to the fertilizer treatments, with the local landrace exhibiting maximum plant height and biological yield, and improved Hashim-08, showing increased agronomic parameters, including the number of tillers and grains and spike length. Application of Zn and KO fertilizers significantly enhanced agronomic parameters, such as the number of grains per plant, spike length, thousand-grain weight, grain yield, harvest index, Zn uptake of grain, dry gluten content, and grain moisture content, while crude protein and grain potassium remained relatively unchanged. The soil's Zn and K content dynamics were found to vary among treatments. In conclusion, the combined application of Zn and KO fertilizers proved beneficial in improving the growth, yield, and quality of wheat crops, with the local landrace exhibiting lower grain yield but greater Zn uptake through fertilizer application. The study's findings highlight that the local landrace showed good response to the growth and qualitative parameter when compared with the Hashim-08 cultivar. Additionally, the combined application of Zn and K showed a positive relation in terms of nutrient uptake and soil Zn and K content.
小麦作物的生长和生产力取决于锌（Zn）和钾（K）等必需养分的有效性，这些养分在植物的生理和生化过程中起着关键作用。本研究旨在调查2019 - 2020年生长季期间，在巴基斯坦德拉伊斯梅尔汗，锌肥和钾肥对Hashim - 08品种和当地地方品种养分吸收、生长、产量及品质的协同效应。试验采用随机完全区组设计的裂区模式，主区为小麦品种，副区为肥料处理。结果表明，两个品种对肥料处理均有积极响应，当地地方品种表现出最大株高和生物产量，改良后的Hashim - 08表现出农艺参数增加，包括分蘖数、籽粒数和穗长。施用锌肥和钾肥显著提高了农艺参数，如单株粒数、穗长、千粒重、籽粒产量、收获指数、籽粒锌吸收量、干面筋含量和籽粒含水量，而粗蛋白和籽粒钾含量相对保持不变。各处理土壤中锌和钾含量动态存在差异。总之，锌肥和钾肥的配合施用被证明有利于提高小麦作物的生长、产量和品质，当地地方品种籽粒产量较低，但通过施肥锌吸收量较大。研究结果表明，与Hashim - 08品种相比，当地地方品种对生长和品质参数表现出良好响应。此外，锌和钾的配合施用在养分吸收以及土壤锌和钾含量方面呈现正相关关系。
