Root system formation and potato productivity using various methods of humic phytobiocomplexes |
|
|
The problems of correlation between the development of the root system of potato plants and the formation of tuber harvest are considered. Evaluation of the fractional composition of the crop of tubers revealed that it was formed mainly due to the average fraction, which has a close relationship with the working surface of the roots (r2 = 78.08). The yield of potato tubers, using new types of fertilizers, phytobiocomplexes, on mineral and organic background amounted to 3.08 - 4.07 t / ha and 5.69 - 6.4 t / ha when added to the row, respectively. The collection of dry matter when using the application of application in a row of humic phytobiocomplex on an organic-mineral background amounted to 5.85 t / ha, against the control 3.7 t, and starch more by 1.01 t/ha.
