In corn farming, growers often face the issue of white seedlings during the early growth stages. These seedlings typically show pale yellow to white leaves at the 3–5 leaf stage, or exhibit chlorotic stripes. As the plant reaches the jointing stage, yellowish-white streaks may appear between the leaf veins and margins, forming broad white patches or bands, and in severe cases, the mesophyll may disappear entirely. The leaves become translucent, resembling plastic film or white silk, and are easily torn by the wind. Some plants also display stunted growth and difficulty in unfurling new leaves. By the time of harvest, the ears often show symptoms such as missing kernels, barren tips, uneven kernel arrangement, or sparse grain filling.
The primary cause of this condition is a deficiency in boron and zinc. Boron plays a key role in regulating carbohydrate metabolism and is essential for protein synthesis, seed development, cell wall formation, pollen germination, and pollen tube elongation. When boron is lacking, pollination and fertilization suffer, leading to sparse kernels and barren tassels. Zinc, on the other hand, helps regulate the synthesis of indole acetic acid and carbohydrate formation. A zinc deficiency can result in stunted growth, smaller leaves, and reduced plant height. It also participates in various enzymatic reactions and influences chlorophyll production. A lack of zinc can lead to white shoots, with photosynthetic rates dropping to about one-third of normal levels. Additionally, zinc affects pollen viability, so its deficiency can cause poor kernel development at the tip of the ear.
To address boron and zinc deficiencies in corn, it’s important to apply appropriate fertilizers at the right time. A combination of soil application and foliar feeding is commonly used. Most nutrients come from the soil, so in fields with severe deficiencies, it's crucial to replenish the soil. For example, 200–400 grams of large-grain zinc or thorium granule zinc per mu, and 200–400 grams of large-grain boron or boron fertilizer can be applied. At the seedling stage, top-dressing with these nutrients can also help. Mixing them with organic or compound fertilizers enhances their effectiveness.
Foliar application offers quick results and high efficiency. During the seedling and jointing stages, a 2000–3000 times dilution of Kainfeng zinc and a 1000 times dilution of Kainfeng boron can be sprayed. Seed treatment with Suifeng Zinc and Pongfeng Boron is another effective method. Typically, 1–2 kg of corn seeds can be treated with 1 ml of Bengfeng zinc solution, which helps promote germination and strengthen seedlings. This practice not only improves early growth but also enhances overall crop resilience.
