Fertilisation Practices in Oilseed Rape in Romania

Fertilisation practices are not yet a key point in oilseed rape production in Romania. There are many factors influencing the current state of affairs, but one of the most important is the lack of information for Romanian farmers regarding specific influence of each fertiliser on oilseed rape yield. An experiment conducted under the field conditions at SCDA Braila has revealed that both fertilizes, nitrogen and phosphorus have to be used in order to produce the highest yields. The highest yields were obtained using 80 kg P2O5 /ha and 100 to 200 kg N/ha. When nitrogen or phosphorus fertilisers were missing, the lowest yields were obtained. Nitrogen is the most important fertiliser for oilseed rape. According to the experiment conducted in Murgeanca (Ialomita County) and to many field observation in the last few years, the role of sulphur in oilseed rape fertilisation practices has to be reconsidered by the Romanian farmers. Nitrogen, phosphorus and sulphur fertilisers have to be use together in order to produce the highest yields in oilseed rape. In high pH soils, the highest yields were obtained using ammonium sulphate applied before sowing.
