Response of spring wheat to different soil and foliar fertilization
2017, 18 (2) p. 460-476
In the years 2013-2015 a field experiment was carried out, whose aim was to determine the response of spring wheat cultivar Arabella to different levels of soil fertilization with NPK and foliar feeding Plonvit Zboża. Higher level of soil fertilization with NPK caused an increase in the LAI (Leaf Area Index), MTA (Mean Tip Angle) and SPAD (Soil Plant Analysis Development) indices in comparison to lower fertilization level. The applied soil fertilization and foliar application did not differentiate the number of plants after emergences and prior to the harvest. The higher dose of NPK caused an increase in the number of ears per 1 m2, TGW and grain yield in comparison to the lower dose. Two-time and three-time foliar application caused an increase in MTA and SPAD indices, while TGW and grain yield increased three times in comparison to the control. The higher level of NPK fertilization caused an increase in total protein, K, Cu and Mn contents in grain and a decrease in Fe content. Three-time foliar application caused an increase in ash and Mg contents in grain in comparison to the control. An increase in Cu and Zn contents, in comparison to single foliar application and the control, was also observed.
