Description

The object of study - the seed potatoes. Purpose - to develop and optimize the basic production methods of potato seed material in the direction of intensification of cultivation to base seed varieties adapted to the conditions of the southwest forest-steppe on the basis of application of plant growth bioregulators and chelated micronutrients on the basis of the improved when breeding material seed potatoes new potato varieties and install potato varieties that are highly adaptive ability to form high yields in a field. Getting the planned number seed potato zoned and promising varieties. Methods of research - field and laboratory and field experiments, analysis, mathematical statistics. Theoretical and practical results: The effect of the application of plant growth regulators on the performance of the material to base potatoes for different planting density and studied performance to base planting material of new varieties of potato in a southwest part of the forest-steppe of Ukraine .. During the reporting period, the analysis of the results of research on the impact of the application of plant growth regulators on performance to base material of potato varieties Treasury of the different planting density showed that the highest yield of tubers produced in the embodiments where conducted before planting treatment of tubers Regoplantom (50 ml / t) and spraying of vegetating Plant Regoplantom 50ml / ha in the phase of budding and sprouting in the planting scheme, see 70h24. So, for 2 years of observations on this variant yields clonal material was 21.9 t / ha (an increase to the control was 5.0 t / ha). According to the super super elite - 18.2 t / ha (an increase of 4.1 to control t / ha). Several smaller increase to control (4.3 t / ha - a hotbed of testing clones; 3.5 t / ha - a hotbed of super super elite) is obtained for the planting scheme, see 70h26. Such use of drugs to an increase in capacity stebleutvoryuyuchoi tubers, to increase the number of tubers under a bush and marketability of the crop. Among all the varieties, which were investigated under the conditions of 2015, August 23, the highest yield formed the middle-grade Outskirts (16.9 t / ha) and early maturing Cimmeria (16.8 t / ha). Novelty. The features to base cultivation of a potato with growth regulators to increase performance culture and identify potato variety, the biological properties of which the most consistent soil and climatic conditions of the region. The effectiveness of implementation. The use of plant growth regulators at the improved breeding of new varieties of seed potatoes that are highly adaptive ability to form high yields in a region provides an economic benefit - 1300-1500 UAH. Scope of use - agriculture, elitgospy growing potatoes.
