Abstract

Wheat (Triticum aestivum L.) is the staple food and second most important food crop after rice in the country, which contributes nearly one-third of the total food grains production. It is consumed mostly in the form of bread as “Chapati”. Wheat straw is used for feeding cattle. Wheat contains more protein than other cereal and has a relatively high content of niacin and thiamine [1]. It is basically concerned in providing the characteristics substance “Glutin” which is very essential for bakers. The production potential of wheat crop is the resultant of a number of interacting factors contributing its shares. Major nutrients (N, P and K) are important for increasing the crop production. However, farmers in this region generally used only nitrogen or nitrogen and phosphorus fertilizers. Intensification of cropping system with greater use of potassium free chemical fertilizers and adoption of high yielding varieties have resulted in the mining of soils leading to K deficiency. There is immense scope of increasing productivity through adequate application of [2]. Wheat has proved to have a higher agronomic K efficiency as indicated by a greater relative yield under K deficient conditions [3]. Better growth and yield of wheat crop has been observed with the addition of’ K [4], Potassium content in the plant tissue is crucial to the proper functioning of several important biochemical and physiological processes that directly determine crop productivity. Therefore, for sustaining soil fertility and optimum crop productivity on long term basis, K removal through the crops should be replenished with balanced and adequate K fertilization.
不同钾锌施用水平对小麦生长和产量的影响
小麦(Triticum aestivum L.)是该国的主食和仅次于水稻的第二大粮食作物,占粮食总产量的近三分之一。它主要以面包的形式被食用,称为“Chapati”。麦秸被用来喂牛。小麦比其他谷物含有更多的蛋白质,烟酸和硫胺素含量也相对较高[1]。它主要涉及提供对面包师非常重要的特性物质“麸质”。小麦作物的生产潜力是影响其份额的若干相互作用因素的结果。主要养分(氮、磷、钾)对提高作物产量很重要。然而,该地区的农民普遍只使用氮肥或氮磷肥。强化种植制度,大量使用无钾化肥和采用高产品种,导致土壤开采导致缺钾。通过适当的应用[2],提高生产力的范围是巨大的。小麦已被证明具有更高的农艺钾效率,这表明在缺钾条件下小麦的相对产量更高[3]。添加钾后,小麦作物的生长和产量都有所提高[4]。植物组织中的钾含量对几个重要的生化和生理过程的正常运作至关重要,这些过程直接决定了作物的产量。因此,为了长期保持土壤肥力和作物的最佳生产力,应在作物脱钾的基础上补充平衡充足的钾肥。
