FORMATION OF VITALITY TACTICS OF MAIZE AT DIFFERENT PLANTING DENSITIES OF HYBRIDS OF DIFFERENT MATURITY GROUPS
Tsyhanskyi Viacheslav – Candidate of Agricultural Sciences, Associate Professor of the department of plant and horticulture of Vinnytsia National Agrarian University (21008, Soniachna Str. 3, Vinnytsia, e–mail: tsiganskiyslava@gmail.com).
Mykutskyi Yury – graduate student of the department of plant and horticulture of VNAU (21008, Vinnytsia, 3 Sonyachna St., 0960368054).
During a two-year research cycle, the vitality of maize agrocenosis of FAO hybrids in the range of 200-300 at seven planting densities from 40 to 100 thousand plants/ha with a technological variant of 10 thousand plants/ha was assessed. The evaluation included the use of indicators of maize plant vital tactics with the assessment of morphological blocks of plants by indicators that determine the intensity of growth processes and the dynamics of aboveground biomass formation and was based on the proven positive correlations between the indices of morphometric development of plants and their predicted productivity. The main indicators of the vitality state of the agrocenosis used were widely tested indicators (which, incidentally, were first used in this way on maize), in particular, the vitality coefficient, the agrocenosis quality index, and the agrophytocenosis prosperity index. Based on the results of recording the main morphometric parameters of plants, namely: plant height (cm), stem diameter at the base (cm), height of the lower cob attachment (cm), number of leaves per plant (pcs.), area of the inflated leaf (cm2), area of the assimilation surface per plant (cm2), cob length (cm), cob diameter (cm), number of rows of grains (pcs. ), number of grains in a row (pcs.), weight of 1000 grains (g). an average array was formed, which allowed to determine the derived values of the optimality of the corresponding planting densities of hybrids of different maturity groups and to link them through the value of the vitality coefficient (IVC) with the level of yield of hybrids and the overall level of their bioproductivity. As a result, conclusions were drawn on the agrotechnological regulations of planting densities for hybrids of different maturity groups on an unfertilised background on grey forest soils in the Forest-Steppe of right-bank Ukraine. Proposals are also made on the prospects for the use of vitality approaches in the search for optimal technological solutions for the development of individual components of adaptive technologies for growing corn for grain.
