EFFECT OF FERTILIZERS WITH MICRO ELEMENTS ON PRODUCTIVITY OF MAIZE HYBRIDS OF DIFFERENT GROUPS OF RIPENESS
Abstract
In the article we give the results of study of the effects of liquid complex fertilizers with micro elements of OOO ‘VolskiBiochim’ (Nizhny Novgorod) on field germination, survival rate of plants to harvesting, productivity, economic and energetic efficiency of maize hybrid cultivation. In the process of study we used maize hybrids of different groups of ripeness; they are a mid-early hybrid ‘Zernogradsky 282 MV’ (FAO280) and a mid-ripening hybrid ‘Zernogradsky 354 MV’ (FAO350). The hybrids ‘Zernogradsky 282 MV’ and ‘Zernogradsky 354 MV’ produced the largest harvests of 3,61 t/ha and 3,93 t/ha while using ‘MicroMak’ for a seed processing and ‘Micro El’ for a plant processing. The economic accounts showed that the hybrids gave a conventional net income of 11679-13853 rub/ha and profitability of 86-101% after using of liquid complex fertilizers with micro elements ‘MicroMak’ for a presowing seed processing and ‘Micro El’ for a plant processing during vegetation. The analysis of energetic efficiency of the maize hybrids showed that these variants of the experiments gave a larger net energy income of 40,68-45,39 GJ/ha and a coefficient of energy efficiency of 3,91-4,22 GJ/ha. In all variants of the experiments a mid-ripening hybrid ‘Zernogradsky 354 MV’ showed higher figures of productivity, economic and bio energetic efficiency than a mid-early hybrid ‘Zernogradsky 282 MV’.
