In corn farming, farmers frequently encounter the issue of white seedlings during the early growth stages. This condition is characterized by pale yellow to white leaves in the 3-5 leaf stage, or by chlorotic stripes appearing on the leaves. After the corn enters the jointing stage, yellowish-white chlorotic streaks may develop between the leaf veins and margins, forming wide, whitened areas or bands. In severe cases, the mesophyll tissue may disappear entirely, leaving the leaves translucent and fragile—like a thin plastic film that can easily tear in the wind. Some plants may also exhibit stunted growth and difficulty in leaf emergence. By harvest time, the ears often show symptoms such as missing kernels, barren tips, uneven kernel arrangement, or sparse grain filling.
The primary cause of this issue is a deficiency in essential micronutrients, particularly boron and zinc. Boron plays a critical role in regulating carbohydrate metabolism and is vital for protein synthesis, cell wall formation, pollen germination, and pollen tube elongation. A lack of boron leads to poor pollination and fertilization, resulting in sparse kernels and barren ears. Zinc, on the other hand, is essential for the synthesis of indole acetic acid and carbohydrate metabolism. Deficiency in zinc can stunt plant growth, reduce leaf size, and lead to dwarfed plants. It also affects various enzymatic reactions and chlorophyll production. As a result, zinc-deficient corn may display white shoots, with photosynthetic activity reduced to about one-third of normal levels. Additionally, zinc is crucial for pollen viability; its deficiency can lead to incomplete kernel development at the ear tip.
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 typically recommended. Most nutrients are absorbed through the soil, so in fields with severe deficiencies, soil replenishment is essential. For example, 200–400 grams of large-grain zinc or thorium granular zinc per mu can be applied, along with 200–400 grams of large-grain boron or boron fertilizer. At the seedling stage, top-dressing can also be effective. These nutrients can be mixed with organic or compound fertilizers for better absorption.
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-fold dilution of Kainfeng boron can be sprayed. Seed treatment with Suifeng Zinc and Pongfeng Boron is also beneficial. Typically, 1–2 kg of corn seeds can be treated with 1 ml of Bengfeng zinc solution, which helps promote germination and strengthen young plants. These practices not only improve crop health but also enhance yield potential and overall productivity.
