Factors affecting Maize yield

China's corn planting area is still relatively broad, and the emergence of hybrid corn makes corn yield on a level, corn yield is getting better and better every year, which is related to many reasons, so today we want to understand is the impact of corn yield reasons, but because of the impact of corn yield there are many reasons, so the following is a small compilation of several more important reasons, let's take a look.

1. Variety selection

Now corn varieties are diverse, and each variety of resistance is also different, such as drought resistance, disease resistance, cold resistance, waterlogging resistance and so on. In order to improve maize yield and make maize yield not affected by variety factors, we need to consider all aspects of factors of maize planting location before selecting varieties.

2. Planting conditions

The influence of planting conditions on corn yield is mainly manifested in three aspects: temperature, soil and light, because if the planting conditions are not conducive to corn growth, then even if the varieties are selected well, it will not make up for it. Therefore, planting conditions are also an important factor affecting corn yield, and they are also the basic conditions for corn growth. Then we need to choose the right planting land for planting.

3. Density management

In the above two basic conditions are not a problem, then the planting density will also affect the yield of corn, because corn growth needs a certain amount of light, so if the planting density is too large, then the field will appear gloomy, thus affecting the growth of corn, and finally affecting the yield of corn. There is also the reason why too much density affects pollination, which eventually leads to corn yield reduction. If planted at normal density, the cobs will be much larger and the yield of corn will increase.

4. Water and fertilizer management

Water and fertilizer are a key reason affecting corn yield. We usually achieve the goal of improving corn yield by strengthening the management of water and fertilizer. If there is too much water in the field, corn seedlings will rot and other diseases will occur, which will lead to corn yield reduction. Secondly, if there is too little water, corn seedlings will die, which will also lead to yield reduction. Then, if there is too much fertilizer or improper fertilizer application, corn yield will be reduced. However, less fertilizer and fruit will lead to malnutrition of corn, which will eventually lead to yield reduction.

5. Weeding management

Weeding is an important step in corn planting. We all know that weeding can promote the growth of corn roots and corn seedlings. At the same time, it can also promote the growth of corn cobs. To a certain extent, it can also enhance the resistance of corn, thus improving the yield of corn. However, if weeding is not carried out reasonably in the process of corn planting, it will first lead to nutrient loss, secondly, it will attract many pests, and then the growth rate of corn will slow down. Missed the best fruiting period and ripening period, resulting in reduced corn yield.

6. Disease management

In fact, there are many diseases and insect pests in the whole growing period of corn. Once the vigilance is relaxed and the control is not in place, the damage to corn is very large, because it is not only the impact on single corn, but on the whole corn. Therefore, the management of diseases is also an important reason affecting corn yield.
