Agroecological aspects of the use of humic phytobiocomplexes in the cultivation of potatoes |
|
|
The use of the method of introducing paste-like humic phytobiocomplexes into a row during potato cultivation provides reliable high tuber yield indicators both against a mineral background (24.52 t/ha) and against an organic-mineral fertilizer (25.98 t/ha), against the control 20,44 t/ha and 20.3 t/ha. A high correlation between the number and weight of large and medium tubers, and biological productivity r2=0.65-0.78 and 0.74-0.76; the dry matter content was 21.23-21.50 %. The collection of dry matter and starch in products obtained on the organic-mineral background, using the methods of processing tubers and adding to the row, amounted to 5.36-5.85 t/ha and 3.19-3.41 t/ha, respectively.
