It is quite natural that the sowing period of winter wheat has a great influence on the yield, development, growth, and resistance to various pests. It has been proven that the optimal period for sowing winter crops is the period from September 25 to October 5. If the procedure is carried out on time, the plants will have time to open up, form a root system, sprout and become resistant to low temperatures.
The above-mentioned terms are almost always taken as a reference point in Ukraine during sowing, cultivation, in order to harvest a healthy crop in the future. If sowing is done much earlier, then the plants will bush too much, start up shoots earlier, gain a large mass and will be vulnerable to both cold weather and pests.
Carrying out work in the late period also does not give particularly fruitful results. In this case, the sprouts will have no more than three to four leaves, which is very few, and the root system will not be fully formed. In this case, winter wheat lags behind in development and does not collect the required amount of moisture from the soil, since it mainly occupies the top layer of the soil. Low yields and low drought tolerance will result.
It is also important to consider the type of plant, soil moisture. If the land is wet enough, then sowing is performed behind unpaired previous crops. The seed placement depth affects the quality of seedlings.
Timely soil preparation to standards is also important. Consider:
If you are in an area with high humidity, then you should devote more time to weed control, fertilization, and optimization of the nutritional process. In arid regions, however, there is a struggle to maintain moisture.
It is important to improve the surface of the soil, and this is done best after rains. It is necessary to loosen the earth, otherwise earth will form on the surface"flew", with which you will then have to fight with the help of an additional passage technique. This is not only the cost of fuel and lubricants, but also a deterioration in the quality of arable land, which leads to a decrease in the future harvest.
In sowing, depth plays an important role - the seeds should not fall into the upper, dry layer, but into the lower, wet layer. This affects the amicability of shoots and then the growth rate of shoots. Moreover, if sowing occurs in an excessively deepened furrow, there is a chance of poor resistance to agrometeorological conditions and the death of sprouts. The best immersion is 3 centimeters.
If there were perennial grasses in the fields before, then they must be harvested a month before sowing. After that, the plow is loosened to a depth of 12 centimeters in order to improve the quality of the soil and the resistance of winter crops. After legumes, the land is plowed by 25 cm. Further, taking into account the activity of weed growth, additional cultivation is carried out.
Observing the requirements, you will receive amicable and full shoots with a branched root system and intensive tillering. Depending on the characteristics of the land, a different degree of sowing is offered:
It is also taken into account that each centimeter of the depression increases the temperature of the environment by about 3 degrees. If sowing is carried out by 4 centimeters, and the temperature of the upper layer is –25 ° С, then at a depth it will be 12 degrees.
