Pisum sativum L. (field or garden pea), is widely cultivated in Europe. The purpose of this investigation was to see whether pea varieties differ in their yield and content of protein and nutrients. Another aim was to select the best varieties suitable for breeding or production. A field experiment with different varieties of peas (‘Bruno’, ‘Capella’, ‘Clara’, ‘Mehis’ and ‘Vitra’) was carried out at the Estonian Crop Research Institute in 2014. Yields (t haE-1) were not statistically different. Crude protein content (g kgE-1 in dry matter) was lowest in ‘Clara’; all other varieties had a higher content of protein, within much the same range. The lowest N content was found in ‘Clara’, followed by ‘Capella’ and ‘Vitra‘, ‘Mehis’ (44) and the highest in ‘Bruno’ (45). The lowest P content was found in ‘Clara’, followed by ‘Capella‘ and ‘Vitra’; the highest was found in ‘Bruno’ and ‘Mehis’. The lowest K content was found in ‘Mehis’, then ‘Clara’, followed by ‘Capella’ and ‘Vitra’ and the highest in ‘Bruno’. The lowest Ca content was found in ‘Clara’, followed by ‘Capella’ and ‘Mehis’, ‘Vitra’, and highest in ‘Bruno’. The lowest Mg content was found in ‘Capella’, followed by ‘Clara’ and the highest in the other varieties ‘Bruno’, ‘Mehis’ and ‘Vitra’. Thus, choice of the right variety for pea cultivation is very important, but depends on the local agro-climatic conditions. This investigation has been developed with the help of the project EUROLEGUME, funded from the European Union Seventh Framework Programme for Research, Technological Development and Demonstration under the grant agreement no. 613781.
