Cherednychenko V. The creation of conveyer and improvement of its basic technology elements of cauliflower growing in the conditions of the conditions of the Right-Bank Forest-Steppe of Ukraine

The dissertation is devoted to the questions of the basis technological elements of cauliflower conveyer growing in the conditions of the Right-bank Forest-steppe of Ukraine. The expedience of cauliflower seedlings growing in cassettes for the first term (the first decade of April) with the size of cell 6x6 cm, for the second term (the 25th of April) and for the third period (the 15th of April) is proved in the cell 4x4 cm. The cauliflower highest productivity (26.8-31.1 t per ha) is got with sowing on the 16th of April using the unseedling method of growing. The next terms of sowing (the 15th of May, the 25th of May, the 15th of June) have provided the lower productivity, but they are promote for the harvest conveyer coming during summer and autumn months. The higher productivity is got is got with such terms of sowing as the 5th of June (20.0-22.3 t per ha) and the 25th of June (17.2-18.2 t per ha), the greatest percentage is of the first sort harvest in its structure. Other terms are less productive, but they give the possibility for the harvest conveyer coming from the third decade of July to the first decade of November. The efficiency of cauliflower growing under temporal tunnel shelters of agrotextiles is proved. The unseedling growing method is the best method for upgrowing plants. The harvest conveyer cauliflower coming was enabled from June to December due to the all above mentioned methods. The plants placing 75x25 cm is optimal. The average productivity during three years was 25.1-26.9 t per ha. The hybrids Vinson F1, Nautilus F1, Fremont F1 are the most productive in the conditions of Right-Bank Ukrainian Forest-Steppe using drop irrigation. The biopower efficiency coefficient is 1.05-4.64 depending on the researched technological elements. The main research results have been production tested and are recommended in its application.
