2022

Green manure is now increasingly used in crop production for many reasons, including its ability to improve soil structure and fertility, and to capture nutrients for the following crop. This study is aimed to determine the promising mixtures of green manure crops in four different organic farms under variable meteorological conditions in 2022. Three different mixtures were grown in four different locations in Latvia: (1) oats (Avena sativa), mustard (Sinapis alba), oil radish (Raphanus sativus ssp. oleiferus), buckwheat (Fagopyrum esculentum) (non-legume), (2) oats, buckwheat, peas (Pisum sativum) (legumes below 50%), and (3) oats, lupine (Lupinus angustifolius), vetch (Vicia sativa) (legumes above 50%). Yield of green biomass in the farms ranged from 14.22 to 26.03 t haE−1. The mixtures with the proportion of legumes below 50% had a significantly (p is less than 0.05) higher yield of green biomass in all farms except “Mazbungas” Ltd with higher yield of mixture with legumes above 50%.
