We asked the expert: When is the ideal time for inter-row cultivation of corn and what is important to know?

Interrow cultivation of corn is a very important agrotechnical measure in its production. It is important to know when it is the right time to perform it, but also what you should pay attention to when performing it. We received answers to these questions from Dr. Goran Bekavac from the Institute of Field and Vegetable Crops in Novi Sad.


Do not do inter-row cultivation in the morning

As our interlocutor says, we need to help corn more in the initial stages grows until the plant develops sufficiently and strengthens, and until it forms rows. Assembling rows implies that when a plant develops well enough it actually does makes a shadow on land surfaces and thus interferes weed development.

“It would be optimal to follow.” eighth leaf do the first inter-row cultivation. The six-leaf plant is still small, thin and there is danger, especially in the soils that are heavier mechanical composition that when passing the machine slabs that hard ground damage plants“, Said Bekavac for our portal.

Our interlocutor adds that inter-row cultivation does not work before noon because the plants are then too brittle and hydrated. Therefore, maize cultivation is recommended from 12 o’clock and further when plants are much easier to bear the passage of mechanization.

“Also, you need to take care of how to adjust cultivator hoes that they do their job properly, that is, to get as close as possible to the order of the plant, and at the same time do not damage the root. If you spread the working elements of the cultivator too far and it goes too close to the plant and cuts off a part of the root, then you have done a lot of damage “, advises Bekavac.

He adds that the optimum should be found in between working width, that is, the working widths cultivated by the interrow cultivator and creating a safe zone where we should not enter and thus injure the plant.

This expert also reminds why inter-row cultivation of corn is increasingly important. Expires tri the most important reason.

Interrow cultivation destroys weeds and improves aeration

“Namely, when you do inter-row cultivation, then you perform shaking the surface layer soil, that is, you improve aeration. This improved aeration has a very positive effect on the plant itself, the root has a much better, let’s call it, breathing, we accelerate everything metabolic and physiological processes in the plant. The difference between cultivated and uncultivated part is very obvious, the naked eye can see how cultivated plants they progress better and faster“, Said our interlocutor from the Institute of Field and Vegetable Crops.


Another very important thing, he points out, is that inter-row cultivation we destroy weeds in the inter-row space and thus reduce the number of weeds, and thus their competitive ability. Weeds can take away 30 or even 50 percent yield.

“The third advantage of inter-row cultivation is reflected in the fact that in this way he improves himself temperature regime land, which means that such land is better and heats up faster“, Bekavac pointed out.

He adds that with two inter-row cultivations, farmers would get rid of weeds and aerate the surface layer of the soil, which is extremely important for the normal physiological processes of the plant.
