| Popis: | The article is devoted to the study of the influence of different dates of seeding of rapeseed seeds for its integrated cultivation on the biometric indices and productivity of the plant and the substantiation of the elements of the technology. In the work it is scientifically substantiated and proved the possibility of seeding the seeds of turnips in earlier spring periods, which contributes to the best use of moisture seeds, both for its germination, and for the passage of phases of growth and development of the plant. With the increase in air temperature and soil for seeding in the third decade of April and the first and second decades of May, and the reduction of moisture in the soil, the long development of the rapeseed plant is provided. It was established that seeding of rapeseeds in the first and second decades of April provides the best biometric indices. Plants of varieties of Purpurova and Purpulepop are formed on 6-19 % more leaves and the largest leaf area. On the basis of the conducted researches, it was proved that seeds should be sown in the first decade of April, which provides the highest yield, which can be 20,6-22,7 t / ha, at later sowing periods the yield of the root crops is reduced to 12,6 t / ha. Among the varieties, the most productive variety is the Purpulepop turnip, which amounts to 22,7 t/ha for seeding in the first decade of April. |
