• Abstract:

  Water availability is a recurring factor in agriculture, therefore, ways to optimize it are sought and in the case of wheat crops, to lower the irrigation depth. That is why, in early sowing dates, the best option is to carry out the first irrigation at the beginning of heading and the second at the formation of watery grain, with this we would be obtaining an increase of more than 10% in yield, than if we apply the first irrigation at the beginning of heading. Losses in production may also occur at the beginning of milky grain formation. In late sowing dates, the highest yield is obtained at the beginning of heading and the beginning of milky grain formation, with the first and second irrigation respectively.
