The yield, height and content of protein of field peas (Pisum sativum L.) in Estonian agro-climatic conditions
Kokkuvõte
Pisum sativum L. is important protein crop in the world. The purpose of this
investigation was to see whether pea varieties differ in their yield, height and content of protein.
Another aim was to select the best varieties suitable for production. Field experiments with
different varieties of peas (‘Bruno’, ‘Capella’, ‘Clara’ and ‘Vitra’) were carried out at the Estonian
Crop Research Institute in 2014 and in 2015. Yields (t ha-1
) in 2014 and 2015 did not differ much,
while yield from variety ‘Bruno’ was very different between years 2014 and 2015 and was much
higher in 2015. The most suitable height of field peas is in a range of 60...100 cm, because the
plants with such a height are most effectively suppressing weeds. It can be concluded that
varieties with suitable height in our investigation were: ‘Bruno’, ‘Capella’ and ‘Clara’. Variety
‘Vitra’ was too high, is lodging easily and is therefore hard to harvest. Crude protein content (%
in dry matter) was lowest in ‘Clara’; all other varieties had a higher content of protein, within
much the same range. Based on the results of present investigation it can be concluded that out
of those four varieties the most suitable varieties for production are ‘Bruno’ and ‘Capella’. Choice
of the right variety for pea cultivation is very important, but depends on the local agro-climatic
conditions. As in Baltic – Nordic countries and in north of America the agro-climatic conditions
are more or less similar the results are useful for those countries.
