Irrigation of sugar beet

Sugar beet is a very sensitive crop to irrigation. In fact, to increase the productivity of the beet it is essential to supply the right amount of water at the most appropriate time. Lack of water support or errors in the timing of water administration can cause serious damage to the entire crop. Irrigation allows to significantly increase the yield of beet. In the initial phase of growth it is advisable to provide enough water to ensure rapid development of the plants. Once the beets have developed, the irrigations can be carried out in cycles with shifts of about 14 days, also taking into account the climatic trend. The most used water supply technique is the rain one,

How to grow beets

Sugar beet is a plant that is used as a renewal crop, typically between two wheat crops. In fact it is able to leave a soil in excellent condition for the subsequent cultivation. The first fundamental step is deep plowing, to be carried out in summer, after finishing the harvest of the cereal crop. Regarding sowing, the place of cultivation is taken into account. In particular, in areas with mild winters and fairly high temperatures, sowing is done in October to proceed with the harvest in early summer. In areas with colder winters, on the other hand, sowing is postponed to early spring and the harvest takes place in September, when the concentration of sugars in the root is maximum. In the past, sowing was done manually, and later it was necessary to proceed with the thinning of the excess plants. Today we resort to the use of specific equipment that allows to distribute the seed evenly and for this reason the thinning technique is no longer used. The harvest consists in the uprooting of the roots from the ground and in the elimination of the collar of the leaves.

Fertilization of sugar beet

In the initial phase of preparing the soil for the cultivation of sugar beet, it is useful to proceed with abundant fertilization with mature manure or with nitrogen-based mineral fertilizers. Nitrogen fertilization can be carried out entirely during the sowing phase, or it can be divided into two phases: the first fertilization is carried out during sowing and the second during the growth phase of the plant. Sugar beet is a plant that is very affected by the presence of any weeds and can get into serious trouble if you don’t run for cover. In the past, when cultivation was mainly manual, weeding was carried out, which had the purpose of eliminating weeds. Today specific chemicals are used for weeding. Weeding is carried out in the phase before sowing and during cultivation in case of emergencies. Weeding is carried out once the plants have developed, to eliminate the surface crust and to cover the roots during the growth phase.

Sugar Beet: Diseases and Cures

In the event that the sugar beet is sown too early, the seedlings may be exposed to late frosts which can cause pre-flowering. In this case, the plant emits the flower in the same year as sowing, compromising the quality of the root. In the event of any hail, the plant is stimulated to form new leaves and this affects the sucrose reserves present in the root, lowering the concentration of sugars and reducing the quality of the product. The main problems of viral origins are rhizomania and virotic yellowness. The mycoses that can attack beets are puccinia, cercospora and downy mildew. Among the insects harmful to cultivation are the elateridae, the beet flea, the cleono, the aphids, the noctuids and the weevil. Among the pesticide treatments are necessary those against beet fleas and against the cleono. Furthermore, it is essential to intervene with fungicides against cercospora and downy mildew, to avoid losing the entire crop.
