After the first cleaning seeds arrive on dryers. Drying of seeds of a colza, perhaps, the most vulnerable link in all chain of their side job. Even at an insignificant overheat their viability decreases. That is why operators of dryers pass annual recertification, hand over the special on drying of seeds of a colza. All mine dryers are equipped portable strelochny. It is connected with that each mine has the fan for an intake of cold and hot air. Earlier for heating and humidity of seeds of a colza watched on a from the dryer. It seemed, humidity of seeds was in norm, and their viability decreased. At careful check of the mode of drying it became clear that in one of mines seeds were overdried. That's when installed portable thermometers in each mine of the dryer. Now operators of dryers can control process of drying of seeds in each mine.

200 centners and more green material which is very necessary for top dressing of cattle at this time. One shortcoming — when bevelling a summer colza on a green forage in a phase of a butonization or at the beginning of blossoming it practically does not give the second hay crop. Only in favorable conditions at plants can ­ lateral escapes, but green material their small and to leave crops for the second hay crop there is no sense. Because of the extended vegetative period in the conditions of Belarus seeds of a summer colza ripen approximately for a month later, than at the winter; its cleaning on seeds is at a loss. It is necessary to clean a colza when there come short days, plentiful dews and steady rains drop out.

At the correct agrotechnology of cultivation of a colza the qualitative seeds answering to the level of the world market and strict requirements of Kanol turn out: the content of erukovy acid is lower 0,5 percent; the maintenance of glyukozinolat is lower than 25 µmol/g of seeds.

At realization of grain of a winter colza on creameries it has to meet the following requirements: humidity no more than 9 percent; foreign impurity no more than two percent; oil availability not less than 40 percent.

The harvest comes to the end with cleaning of the vegetable remains and a of an eddish. Usually straw of a colza is cleaned and disseminate the remains across the field. On some sites carry out a repeated disking. Hulling or eddishes is necessary not only for preservation of moisture and crushing of the pozhnivny remains, but also the most important — for provoking of germination of seeds of the colza. After all they keep the viability till 10 years and more. The sprouted colza at repeated returns to former sites strongly increases a share of glyukozinolat in seeds and worsens its quality.

If in economy there are no special drying installations, colza grain after cleaning can be finally dried in the way of active aeration. Simple ventilating installations can be made quickly in any storage. The drainage pipes or wooden pallets covered with jute bags can become the air channel for active aeration and ventilating drying.

The summer colza is irreplaceable and for cultivation of green material in poukosny crops. However, at summer terms of sowing (June — July) plants develop in the conditions of the truncated light day. Here such feature is observed — development of plants is late, and growth of lateral escapes happens intensively. By September — October on hectare grows

Some words about an agrotechnology of cultivation of a summer colza. If crops are intended on a green forage, them in the main salting of annual herbs or silage cultures. After cleaning of bean and cereal mixes on a green forage place poukosny crops, and after early the cleaned grain — pozhnivny. Any cultures, except krestotsvetny and flax can be predecessors under a summer colza on seeds. In economy usually it is placed after grains of cultures.

It is necessary to consider that colza seeds by the size it is much less grain, but it is heavier than them on weight. It is necessary to be afraid of blockage of air vents. installations reduce risk and losses at storage. There are enough 10 — 15 cubic meters of air for aeration of a colza that it was stored long time.
