The experiment was based on the block randomized method in four replications, after cotton predecessor in Field Crops Institute, Bulgaria in the period 2018/19-2019/20. Were tested: N40, N80, N120; N160; P40, P80, P120 and P160. As a control variant was adopted N0P0. Based on the results obtained, we can conclude that the maximum nitrogen rate did not lead to the best results. The norm of 120 kg N ha was the most effective in most parameters - grain yield (76.2%); test weight (113.3%); grain vitreous (32.36%); gluten content (50.2%), respectively compared to the control. Thousand kernel weight was most affected by N160 (13.3%). Protein content had the same values in N120 and N160 (35.1%), and this effect does not justify the high rate of N160. Phosphorus fertilization showed a weaker effect for all studied traits, and grain yield did not have significantly higher values. The other parameters were most affected by fertilization with P80: thousand kernel weight (7.7%); test weight (2.0%); grain vitreous (9.69%); gluten content (22.3%), respectively. Protein content had the same values at P80 and P160 (9.0%). [ABSTRACT FROM AUTHOR] |
