Abstract:

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.

Abstract:

Experiments to study the effects of weed harrowing in an organic farming system were carried out during 2005–2007 at the Joniskelis Experimental Station of the Lithuanian Institute of Agriculture on a clay loam Gleyic Cambisol. Spring oat (Avena sativa L.) and field pea (Pisum sativum L.) crops were harrowed once and twice with a Regent spring-tine harrow at pre-emergence, early post-emergence and late post-emergence stages. This study indicates that at early growth stages of crops the uprooting effect of harrowing could be more important for weed control than at late stages. Early post-emergence harrowing (at 2–3 leaf stage) was the most effective for spring oat. Twice (pre-emergence and early post-emergence) harrowing of oat was not more effective than early post-emergence harrowing once, since early harrowing stimulates new sprouting of weeds. Pea crop damage by harrowing was less when the crop was harrowed at late post-emergence (beginning of stem elongation) stage. No difference of crop yield was determined among the treatments.
