Summer corn is in the middle and late stages
Fertilization is a crucial step in corn cultivation to ensure healthy growth and high yield. The first stage involves applying spike fertilizer, typically during the large bell mouth period. This usually accounts for about 50% of the total nitrogen applied throughout the growing season, with approximately 30-40 kg of standard nitrogen fertilizer per mu. The second phase is granular fertilizer application, which generally makes up around 10% of the total topdressing. For this, 10 kg of ammonium bicarbonate is used per acre. When applying the fertilizer, dig a trench about 10-15 cm wide and 9-12 cm deep, located 10 cm away from the plant. After placing the fertilizer in the trench, cover it with soil and water it thoroughly.
In terms of pest and disease control, especially during the ear development stage, various methods can be employed. During the large bell mouth period, you can use 1.5% phoxim granules mixed with 5-6 kg of fine sand per acre, or prepare a 0.1% solution of 50% phoxim emulsifiable concentrate and apply it directly into the corn heart. To manage corn leaf spot disease, spray a 500-800 times diluted solution of 50% carbendazim. For controlling corn rust and brown spot disease, mix 75-100 ml of 20% triadimefon emulsifiable concentrate with water and apply it when the disease first appears.
Emasculation, or removing the male tassels, plays an important role in improving yield. By removing the male parts, plants consume fewer nutrients, allowing more energy to go into ear development. It also helps reduce plant height, improve air circulation, and enhance resistance to lodging. Additionally, it ensures better synchronization between male and female flowers, increasing pollination success. Timing is key—emasculation should be done when the tassel is about one-third to one-half developed. At this point, it's easier to remove the tassel without damaging the plant. It’s best to perform this task between 9 am and 4 pm on a sunny day to allow wounds to heal quickly. Typically, about one-third of the plants are emasculated, not exceeding half, and care must be taken not to remove the male parts of the two rows on the ground to avoid interfering with pollination. Combining emasculation with hand pollination can significantly improve results.
Harvesting at the right time is essential for maximizing yield. Farmers often harvest when the leaves turn yellow and the kernels become hard. However, early harvesting can lead to lower thousand-grain weight, affecting overall yield. The true sign of maturity is the disappearance of the milk line in the kernels. Harvesting at this stage can increase yield by 8%-10% compared to traditional methods. On the same ear, the upper kernels develop and dry out first, while those at the base take longer. Therefore, it’s best to determine the harvest time based on the milk line at the lower part of the ear.
