Statistical analysis of the height of hybrid plants Kn-517 and Kn-613 depending on mineral fertilization and crop density

The study was conducted between 2020 and 2022 in the experimental field of Maize Research Institute-Knezha. subject is following hybrids: Kn-517 group 500-600 FAO with a density 5500 p/da 6000 p/da; Kn-613 over 600 5200 5700 p/da. cultivated hybrids each variation measured height 10 plants. maize grown under control variant T0 – without fertilization two levels: Т1 N8.5P5.4K6.4 T2 N17P10.8K12.8. On average for period 2020-2022 on hybrid highest xaverage = 268.33 cm at fertilized best result 276.00 years 2021 In same year, seed N17P10.8K12.8 maximum Max 285.00 cm. coefficient lowest CV=3.61% CV=4.77% fertilizer This quantity changed by from CV=2.57% to CV=4.35% both densities largest 279.33 279.67 fertilizing indicator had score 2021. year Max=296.00 CV=3.37% N0P0K0 CV=4.90% For this ranged CV=2.53% CV=3.67%
