“…Daytona, on the other hand, has shown excellent lodging resistance, which seems to be a crucial prerequisite in high-yielding environments, like Creston. The importance of lodging resistance to achieve a higher yield in pea has been previously pointed out by others (Annicchiarico and Iannucci, 2008;Podgórska-Lesiak and Sobkowicz, 2013). Our results showed that cultivars with larger seed tended to produce a higher yield.…”

Core Ideas Dry pea yield, protein, and resistant starch varied greatly across Montana. Yield and protein were mainly determined by environments. Resistant starch is controlled by genetics to a great extent. Effects of drought index, growth period, seed size, and seed weight on yield, protein, and starch were analyzed. Pea (Pisum sativum L.) has long been an important component of the human diet, providing an excellent source of protein. In addition to its protein, pea starch, especially resistant starch (RS), has received an extensive attention in food industries in recent years. We evaluated nine pea cultivars varying in cotyledon color, grain weight, maturity group, and phenology planted at five locations with diverse climatic conditions across Montana in 2013 and 2014 to assess genetic and environmental factors affecting their yield, protein, RS, and total starch (TS). Grain yield varied from 982 to 5951 kg ha−1, RS content ranged from 5 to 53 g kg−1, and protein from 159 to 251 g kg−1. Statistical analysis showed that environment was the most important driving factor in grain yield, protein, and TS determination whereas RS content was mainly determined by cultivar. Drought at all phenological stages reduced pea yield and different cultivars tended to respond differently. Yield was positively correlated with protein, implying a potential to select/breed a cultivar with higher yield and protein. Protein was negatively correlated with TS, thus protein‐ or starch‐type cultivars may be bred for different end users. Compared to other cultivars tested, DS Admiral was the most promising one with above average yield, protein, and RS.

“…On the other hand, the high resistance of Huayouza 62 could offer mechanical support to Fengyou 520, which is consistent with the study of intercropping barley (Hordeum L.) with pea (Pisum sativum L.), where the barley provided physical support to pea which prevented the pea from lodging (Podgórska-Lesiak & Sobkowicz, 2013).…”

A split-plot experiment was conducted to alleviate high yield and strong lodging resistance not coinciding with rapeseed (Brassica napus L.). The main plot was planting density (1.2 and 4.5 × 10 5 plants ha −1 ), and the subplots were different intercropping ratios (1:0, 0:1, 2:1, 1:1, and 1:2) of Huayouza 62 (lodging resistance) and Fengyou 520 (lodging sensitive). Our results indicated that increased density significantly decreased biomass, siliques, and yield per plant, but the population yield was enhanced by 9.3%, and intercropping increased leaf area at the bolting and anthesis, dry matter accumulation, and population yield compared to the sole crop. Increased density decreased the root neck diameter and stem breaking strength of per plant but increased the population lodging resistance, and intercropping significantly improved lodging-related agronomy traits, increased stem breaking strength, and stem biochemical contents compared to sole cropping. The average lodging index was decreased by 17.7% and lodging angle by 11.2% at the planting density of 1.2 × 10 5 plants ha −1 deployed at 1:2 intercropping ratio, and at 4.5 × 10 5 plants ha −1 with 1:1 intercropping ratio, the average lodging index decreased 7.8% and the lodging angle by 14.1%. Total population root biomass was significantly negatively correlated with the lodging angle, but positively correlated with the harvest yield. Intercropping rapeseed varieties that differ in lodging resistance at variable density can improve the root traits of the population that alleviate the trade-off between high yield and poor lodging resistance.

“…Intercropping with cereals is often a feasible means to increase yield stability in pea, e.g. through preventing lodging (Kontturi et al 2011, Podgórska-Lesiak andSobkowicz 2013) and having less disease outbreaks (Schoeny et al 2010). Furthermore, the use of legume companions in intercrops enhances suppression of weed growth without reducing crop yields (Verret et al 2017).…”

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.
