Effect of site based fertilization on spring oilseed rape yield and seed quality
The experiments, using two fertilization methods in the spring on oilseed rape in 2012, were carried out at two sites – on the Eerika experimental field (N 58°36.6’; E 26°32.5’), near Tartu and on the Erumäe field (N 58°27.9’ ja E 26°32.5) of Pilsu farm. The aim of the study was to investigate site-...

| description | The experiments, using two fertilization methods in the spring on oilseed rape in 2012, were carried out at two sites – on the Eerika experimental field (N 58°36.6’; E 26°32.5’), near Tartu and on the Erumäe field (N 58°27.9’ ja E 26°32.5) of Pilsu farm. The aim of the study was to investigate site-based precision fertilization on the spring rape yield and oil content of rape seeds. The preceding crop was spring wheat. Five treatments were used: control treatment (K) without fertilizers, conventional fertilizing system (T), fertilization by site-specific information (MI), fertilization by site-specific information additionally with a mineral nitrogen fertilizer (MIMN), and site-specific fertilization additionally with a foliage nitrogen fertilizer (MILV). The highest grain and oil yield levels were achieved in the treatments with fertilized site-specific information additionally with foliage nitrogen fertilizer. On the production field, acceptable grain and oil yield increases were achieved in the treatment fertilized by site-specific information additionally with foliage nitrogen fertilizing. Compared to the conventional fertilization (T), the foliar fertilization (MILV) had, in the field experiment a 6.6% higher rapeseed yield, while in the production experiment this increase was 21.6%. The oil content of the spring oilseed rape seeds was higher in the control and conventional treatments. In both experiments the highest spring rapeseed oil content was obtained from the background foliar fertilizer plots (MILV) – in field experiments this was 1.3–1.7%, while in the production experiment 0.5% higher than the soil information fertilized treatments (MI) only. There was a negative correlation between the oil content and seed yield level, and between the oil content and protein content of spring oilseed rape. |
