“…Sensitivity to lodging differs according to Official Variety Trials: Karita is the most lodge-resistant (28% mean lodged area) followed by Hulda (41%) and Perttu (73%). The lodging sensitivity in the Perttu cultivar was also apparent in this study (Kontturi et al 2011). The oat cultivar Roope was selected as a companion crop as it is an early maturing, lodgeresistant cultivar by Boreal Plant Breeding.…”

“…The soil types were heavy clay in Jokioinen, very fine sand and silty clay in Mietoinen, and sandy gyttja clay in Ylistaro. Additional information about soil conditions has been published earlier (Kontturi et al 2011). Daily weather data was made available for all the experimental sites by the Finnish Meteorological Institute.…”

“…The fertilizer included phosphorus (18 kg ha -1 for oat and 4-6 kg ha -1 for pea), potassium (48 kg ha -1 for oat and 7-16 kg ha -1 for pea) and all essential micronutrients. The nutrient content varied slightly depending on the experiment and according to soil nutrient content and soil type (Kontturi et al 2011). The lower N rate in intercrops was used to facilitate the general success of pea as an N-fixing companion (Hauggaard-Nielsen and Jensen 2001).…”

“…However, intercropping makes the anticipation of yield shares of companion crops uncertain and may challenge the use of harvested yield, e.g., as on-farm feed (Kontturi et al 2011), even though techniques for separation of peas and cereals have developed. Hence, many studies have focused on improving our understanding of the contribution of crop phenological timing and growth dynamics to competition, growth performance and yield formation processes between species in intercrops (Hauggaard-Nielsen et al 2006, Barker and Dennett 2013, Monzon et al 2014, Brooker et al 2015.…”

The cereal often dominates the grain legume in intercrops, especially when sown in larger amounts. This study assessed yield formation of pea (Pisum sativum L.) and oat (Avena sativa L.) in an intercropping system in high-latitude conditions. Three pea cultivars (Hulda, Karita and Perttu) and one oat cultivar (Roope) were grown as sole crops and intercrops with shares of either 7.5% or 15% of oat (as weight of sown seed mixture). Experiments were organized in three (southern, western and northern) locations of Finland for three years. Yield and vegetative above-ground biomass, their land equivalent ratio (LER, i.e., the yield in intercrop compared to that of the component yields in pure stands), and a number of yield components were measured prior to harvest at crop-stand and single-plant levels. The share of oat in the intercrop did not have any impact on variation in LER yield . Oat yield and yield components generally benefitted from a pea companion crop. The pea cultivar Perttu was superior in intercrops: it had a LER yield >1 in seven out of eight experiments (mean LER yield =1.06), while Karita had a LER yield >1 in four (mean LERyield =1.00) and Hulda only in one experiment (mean LER yield =0.98). Perttu proved to be a compatible pea companion for a pea-oat intercrop, likely because it was successful in overcompensating for decline in relative yield (RGY) of oat in intercrops, contrary to Hulda. However, none of the measured yield components of Perttu were associated with LER yield , suggesting compensation ability between them, while in Karita and Hulda, e.g., higher grain yield and number of grains and pods per square meter were associated with decline in LER yield . It was concluded that the success of Perttu as a companion for oat in intercrops is likely attributable to its flexibility in building yield through a variable combination of yield components rather than being outperformed due to some superior traits. Such flexibility, likely attributable to long duration of flowering supports resilience to weather variability that is typical for northern European conditions allowing Perttu to consistently sustain a LER yield >1.

“…In cereal-legume intercropping, cereal crops establish uniform canopy structures and then legume crops and the roots of cereal crops grow to a greater depth than those of legume crops with less lodging consequences [29]; however the agronomic traits of genotypes need to be well adapted for intercropping. Climbing bean cultivars need specific adaptations to intercrops using predominantly morphological maize types grown in the area [27].…”
