Из практики известно, что не все со

Из практики известно, что не все сорта одинаково проявляют себя в одних и тех же условиях их возделывания, поэтому и реализация потенциальной продуктивности у разных сортов идет по разному. Высокопродуктивные сорта выносят из почвы большое количество питательных веществ, расходуют много воды, поэтому такие сорта требуют высокой агротехники. Если таких условий нет, то потенциально более продуктивный сорт не только не дает прибавки, но может и уступить по урожайности другому менее продуктивному, но и менее требовательному к условиям возделывания сорту. Следовательно, нужен дифференцированный подход к подбору сортов. Особенно он важен в настоящее время, когда многие хозяйства не могут обеспечить посевы высокими дозами удобрений и комплексом защиты растений. Вполне очевидно, что экономически слабым и сильным хозяйствам необходим разный сортовой состав.

From practice we know that not all varieties equally manifest themselves in the same conditions of their cultivation, so the realization of potential productivity in different varieties goes differently. Highly productive varieties tolerate large amounts of soil nutrients, consume a lot of water, so such varieties require high machinery. If such conditions are not, potentially more productive variety not only does increase, but may yield to another less productive, but less demanding to conditions of cultivation. Therefore, we need a differentiated approach to the selection of varieties. It is particularly important at a time when many households cannot provide crops with high doses of fertilizers and plant protection products. It is quite obvious that the economically weak and strong farms required different varietal composition.

From experience we know that not all varieties are equally manifest themselves in the same conditions of cultivation, so the realization of potential productivity in different varieties comes in different ways. Highly productive varieties carried out of the soil a large amount of nutrients, consume a lot of water, so these varieties require a high agricultural technology. If these conditions not, potentially more productive variety, not only not increase, but it may give way to the yield of other less productive, but also less demanding of conditions of cultivation of the variety. Therefore, a differentiated approach to the selection of varieties. It is especially important now, when many households can not provide the crops with high doses of fertilizers and plant protection complex. It is clear that the economically weak and strong farmers needs a different varietal composition.

In practice it is known that not all varieties are equally shown themselves to be in the same conditions of their cultivation, therefore, and the potential productivity gains from different varieties are in different ways.Productive varieties being brought out of a large number of soil nutrients, consume a lot of water, and for this reason such varieties require high agricultural engineering. If there are no such conditions,It is potentially a more productive class not only does not give grades, but can be replaced by the yield to another less productive, but less than discerning the conditions cultivation class. Consequently,Need a differentiated approach to the selection varieties. He was particularly important at the present time, when many agriculture could not ensure crops high-dose fertilizers and plant protection complex. It is quite obvious,That the economically weak and strong households requires a different varietal composition.
