Currently, farmers in the same field often plant multiple corn hybrids, such as two or more varieties, using a mixed planting method. This approach can increase grain yield per acre by approximately 20 to 30 kg. The technique requires no additional inputs and is relatively simple to implement. The main reason for the yield increase lies in the utilization of hybrid vigor in corn. Studies on contemporary hybridization in maize have shown that there is a phenomenon known as "pollen sensation" among different varieties. The strength of hybridization follows this order: hybridization > cross-pollination > self-pollination. For instance, the number of kernels per ear, kernel weight, and 100-kernel weight were found to be 40.7, 28.5, and 1.1 grams higher, respectively, in cross-pollinated plants compared to self-pollinated ones.
There are various ways to take advantage of contemporary hybridization in agricultural practices. One common method is to plant multiple varieties on the same plot or interplant several maize hybrids in specific proportions. This helps maximize hybrid benefits while reducing the chances of self-pollination between plants of the same variety, ultimately boosting overall crop production.
However, when mixing different corn varieties, there are several important factors to consider:
1. It is essential to select corn hybrids that are well-suited for local conditions, have strong disease resistance, and are genetically diverse to ensure better hybrid vigor.
2. The chosen varieties should have similar growth periods to increase the likelihood of successful cross-pollination during the flowering stage.
3. The selected varieties should also have the same grain color to maintain the quality and marketability of the harvested grains.
By following these guidelines, farmers can effectively harness the advantages of contemporary hybridization, leading to improved yields and better-quality crops. This method not only enhances productivity but also contributes to sustainable farming practices by making efficient use of genetic diversity.
