Grain Quality of Maize Cultivar Giza 168 as Affected by Levels of Irrigation, Sowing Date, Plant Density and Macronutrients

The analysis of the Crimean weather conditions during the autumn vegetation period of winter wheat indicates climate warming and, in this regard, the necessity to adjust the optimal sowing dates. The purpose of the current study was to estimate the productivity and grain quality of winter bread wheat varieties depending on different sowing dates. The objects of the study were five winter wheat varieties sown in 5 dates from October 1 to November 30 with an interval of 15 days. Field trials were conducted with appropriate observations, records, measurements and analyzes, according to the methodology of the State Variety Testing. Statistical processing of the trials was carried out by the B.A. Dospekhov’s method of dispersion and correlation analyzes. The study was carried out through three years, two vegetation periods of which (2017–2018 and 2019–2020) were dry, one period (2018-2019) was favorable for the development of winter grain crops. According to the results of the analysis of variance, there have been identified significant differences in the effect of all three factors (‘variety’, ‘length’ and ‘year’) and their correlation in all combinations on the productivity formation. The factors ‘sowing date’ (33%) and ‘correlation between date and year’ (49%) had the greatest influence on the productivity formation. In 2018, the most optimal for all studied varieties was the second sowing date (15.10), in 2019 it was the first (1.10), and under the conditions of 2020, the later sowing dates were more favorable, and the 4th period was marked as optimal (15.11). The mean productivity of all varieties at the optimum sowing dates was 4.0; 5.5 and 3.46 t/ha, respectively. The factors ‘sowing date’, ‘year’, and the correlation between them significantly influenced protein percentage in grain. Their effect on the manifestation of the above trait was 29%, 14% and 23%, respectively; on gluten content it was 29%, 16% and 21%, respectively.

The Impact

The purpose of the research is to identify effi cient microfertilizers and growth stimulants considering biologi- cal features of new corn hybrids of different FAO groups under irrigation conditions in the South of Ukraine and trace their impact on grain productivity of the plants. The methods of the research are the fi eld method – to study the interaction of the research object with experimental factors of the natural environment, to register the yield and evaluate the biometrical indices; the laboratory method – to measure soil moisture, grain moisture content and grain quality indices; the statistical method – to evaluate the reliability of the obtained results; the calculation methods – for economic and energetic assessment of the growing techniques used. The results of the research. The paper defi nes the impact of microfertilizers and growth stimulants on the yield and grain quality of the corn hybrids of different maturity groups and on the economic effi ciency of growing them. The conclusions of the research. Under irrigation conditions of the Southern Steppe of Ukraine it is recommended that the following hybrids should be grown in dark-chestnut soils: early maturity DN Pyvykha, medium-early Skadovskyi, medium maturity Kakhovskyi and medium-late Arabat, using the growth stimulants – treating the seeds with Sezam-Nano and fertilizing with Grainactive at the stage of 7–8 leaves.
