Wheat

Irrigation of grain

The wheat is generally sown in autumn or winter; therefore, in the early stages of its development, up to flowering, the rainfall that usually occurs at this time of year should be sufficient to meet the water needs of the crop. Excessive rainfall can cause water stress, but there is not supposed to be a danger of drought. In the period of the granison, between spring and summer, it is instead necessary to intervene, as the lack of adequate watering could cause damage to the yield of the crop. A widespread irrigation method is drip irrigation: it allows the water to be distributed evenly with the so-called drippers, which produce thin jets that wet the surface of the soil or directly the roots.

Cultivation and care


Wheat adapts to different types of soil; particularly important, however, is the tillage of the soil before sowing, so as to make it compact and to favor drainage. A first, fundamental operation is plowing, which is recommended to be carried out with the typical plow plow during the summer season, but it is certainly also useful to practice harrowing and milling: these techniques allow, through special tools such as harrow and tiller, to crush the clods and smooth the soil as best as possible. It is also necessary to eliminate the weeds formed following the previous crop with herbicides. Often the seeds, before planting, are subjected to a fungicide treatment to prevent the onset of diseases in the early stages of plant growth.

Fertilization


Fertilization of wheat must be carried out with products that contain the three main macro elements, namely phosphorus, potassium and nitrogen, and in addition the microelements necessary for the development of plants, including magnesium, iron, boron and zinc. It is recommended to distribute the macroelements according to the previous crop; for example, if the latter is an improver, a high quantity of nitrogen, already widely present in the soil, will not be required. The first fertilization must be performed at the time of sowing, while the second is divided into two phases and must be practiced in the period of raising, when the stems are lengthened, and in that of the barrel, when the ear is now formed. The first fertilization must provide phosphorus and potassium in particular, the second is based on nitrogen.

Wheat: Exposure, diseases and pests


Triticum needs a sunny exposure but does not need high temperatures to develop optimally; both heat and cold, if excessive, are dangerous for the yield of the crop, in particular if too intense winds are added. Among the fungal diseases, powdery mildew is very annoying and widespread, also called white malady due to the whitish mold that forms on plants and can be counteracted with sulfur-based products. Another disease of wheat, known since ancient times, is rust, which manifests itself as dark pustules; as a remedy we suggest the use of natural substances, such as garlic or nettle. Among the parasites, however, the lema should be mentioned,
