What factors affect high wheat yields? The latest analysis is here
Wheat is grown on a very large area in our country. So the wheat market is currently quite competitive, and when growing wheat, everyone wants to increase wheat yields as much as possible in order to improve growing returns. However, if you want high wheat yields, it is not that easy. That is because there are also many factors that affect high wheat yields, so what exactly are the factors that affect wheat yields? Let's take a look together below!
1. Soil factors
Soil is the primary factor affecting high wheat yields. Soil depth, fertility, water content and so on are all closely related to wheat yields. Wheat is suitable for growing in active soil with a relatively deep soil layer, with the tillage layer kept at a depth of about 25 cm. If the soil layer is too shallow, then the wheat will not be able to obtain sufficient water and nutrients as it grows. In addition, we also need to maintain soil that is neither too loose nor too tight. If it is too loose, the soil has poor heat and water retention, while if it is too tight, permeability is poor, and it will affect nutrient availability and the activity of soil microorganisms, affect root growth, and reduce wheat yields.

When growing wheat, many people blindly apply nitrogen fertilizer in order to increase yields. If too much nitrogen fertilizer is applied, then the proportion of phosphorus and potassium fertilizers and organic fertilizers will relatively decline. Wheat is then extremely prone to excessive vegetative growth, field permeability is poor, and wheat plants are also extremely prone to producing large numbers of ineffective tillers, causing a delay in the time of polarization and differentiation, excessively long basal internodes, and wheat plants are also extremely prone to lodging, leading to reduced yields. It will also lead to neglect of the application of trace elements; if wheat lacks trace elements, it is prone to poor growth and thus reduced yields.
3. Sowing factors
The sowing rate and time of wheat are also major factors affecting high wheat yields. If too much wheat is sown, it will lead to increased tillering, an excessively large wheat population, and competition among plants for light and nutrients. This causes some wheat plants to grow excessively while others grow weak and spindly, seriously affecting yields. And if sowing is too early, then it will advance the emergence time of wheat, speed up the growth rate, and also produce many tillers. Excessive seedlings appear before winter, thus causing wheat to lose fertilizer and age prematurely in the middle and later stages of growth, affecting individual growth.
4. Climate factors
Wheat is a crop that likes to grow in a cool environment with sufficient light, and it is a long-day crop. If the temperature is too high in early winter, then it will shorten the growth period of wheat. And if the temperature is too high in the early stage of wheat growth, it will shorten the tillering stage of wheat and its spike-forming rate. If there is high temperature and high humidity in the later stage, it will affect the grain filling of wheat and produce various diseases and insect pests. Furthermore, if there is too much rainy weather, the soil is soft, the light duration becomes shorter, and the stems of wheat also grow very thin and weak. If windy weather occurs, wheat is extremely prone to lodging, and yields will be affected as a result.
The above is a brief introduction to the factors affecting high wheat yields. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
