Lentil (Lens culinaris Medik.) is an important source of protein, starch, and mineral nutrients in many parts of the world. However, the impact of environment and cultivar on the enrichment of these nutrients is not well understood. Four lentil cultivars (‘Avondale’, ‘CDC Richlea’, ‘CDC Maxim’, and ‘CDC Imvincible’) varying in color, seed size, and maturity were evaluated at five Montana locations with diverse climatic and soil conditions over 3 yr. Significant cultivar, location, and year effects were found for yield, protein, starch, and minerals. Grain protein concentration was the highest at Moccasin (262 g kg−1) and lowest at Richland (246 g kg−1), whereas starch concentration was the highest at Richland (455 g kg−1) and lowest at Moccasin(441gkg−1). Among cultivars, Avondale was the top yielding cultivar (1965 kg ha−1)and adaptable to most of the environments; CDC Imvincible was the top protein producer (265 g kg−1); and CDC Richlea is the leading starch producer (456 g kg−1). Grain protein concentration was negatively correlated with starch. Lentil grains varied in nutrient concentrations across locations, with the north central Montana region producing 10- to 20-times greater selenium concentration than other locations. CDC Maxim had the highest iron (62.1 mg kg−1) and zinc (31.5 mg kg−1) concentrations.Seed protein concentration was positively correlated with phosphorus, sulfur, cop-per, and boron. Seed starch is positively correlated with magnesium and manganese.Results suggest that plant breeding and production site selection could enrich lentil nutrient concentrations to help combat malnutrition in the world.
Intercropping chickpea–flax for yield and disease management
(Wiley, 2023-03) Zhou, Yi; Chen, Chengci; Franck, William L.; Khan, Qasim; Franck, Sooyoung; Crutcher, Frankie K.; McVay, Kent; McPhee, Kevin
Ascochyta blight (caused by Ascochyta rabiei) is a primary concern of chickpea production worldwide. Intercropping chickpea with a non-host crop has the potential to suppress this disease and improve resource use efficiency for enhanced crop yield. This study aimed to evaluate the effects of seeding rate and row configuration of chickpea (Cicer arietinum L.)–flax (Linum usitatissimum L) intercropping on (1) yield and seed quality, (2) disease incidence and severity of Ascochyta blight of chickpea, and (3) land productivity of this intercropping system. Field trials were conducted at the Eastern Agricultural Research Center, Sidney, MT, and the Southern Agricultural Research Center, Huntley, MT, in 2020 and 2021. Chickpea was planted with flax in four intercropping configurations (70% chickpea–30% flax in mixed rows, 50% chickpea–50% flax in alternate rows, 50% chickpea–50% flax in mixed rows, and 30% chickpea–70% flax in mixed rows). Chickpea yield decreased with increased flax proportion in the mixed rows intercrop. Flax displayed higher competitiveness than chickpea, resulting in decreased yield and protein concentration in chickpea but increased yield and protein content in flax. Land equivalent ratio of intercropping was greater than one, showing improved land productivity (2%–23% greater than monocropping). Intercropping reduced Ascochyta blight disease incidence and severity; the 50% chickpea–50% flax and 30% chickpea–70% flax intercropping configurations could reduce the disease severity to 50% (in Huntley) and 67% (in Sidney) of that in the monocropping. These results indicated that seed ratio and planting configurations of chickpea–flax intercropping may be manipulated to increase land use efficiency and reduce Ascochyta blight in chickpea. Canadian Development Center ‘CDC Leader’ yielded greater than Royal in the higher disease pressure environment in Huntley indicated that selection of disease resistant cultivars is important for managing Ascochyta blight in chickpea.

Ascochyta blight (caused by Ascochyta rabiei) is a primary concern of chickpea production worldwide. Intercropping chickpea with a non-host crop has the potential to suppress this disease and improve resource use efficiency for enhanced crop yield. This study aimed to evaluate the effects of seeding rate and row configuration of chickpea (Cicer arietinum, L.)-flax (Linum usitatissimum, L) intercropping on 1) yield and seed quality, 2) disease incidence and severity of Ascochyta blight of chickpea, and 3) land productivity of this intercropping system. Field trials were conducted at the Eastern Agricultural Research Center (EARC), Sidney, MT, and the Southern Agricultural Research Center (SARC), Huntley, MT, in 2020 and 2021. Chickpea was planted with flax in 4 intercropping configurations (70% chickpea – 30% flax in mixed rows, 50% chickpea – 50% flax in alternate rows, 50% chickpea – 50% flax in mixed rows, and 30% chickpea – 70% flax in mixed rows). Chickpea yield decreased with increased flax proportion in the mixed rows intercrop. Flax displayed higher competitiveness than chickpea, resulting in decreased yield and protein concentration in chickpea but increased yield and protein content in flax. Land equivalent ratio (LER) of intercropping was greater than 1, showing improved land productivity (2% -23% greater than monocropping). Intercropping reduced Ascochyta blight disease incidence and severity; the 50% chickpea – 50% flax and 30% chickpea – 70% flax intercropping configurations could reduce the disease severity to 50% (in Hunley) and 67% (in Sidney) of that in the monocropping. These results indicated that seed ratio and planting configurations of chickpea-flax intercropping may be manipulated to increase land use efficiency and reduce Ascochyta blight in chickpea. CDC Leader yielded greater than Royal in the higher disease pressure environment in Huntley indicated that selection of disease resistant cultivar is important for managing Ascochyta blight on chickpea.
