Two small faba bean (Vicia faba L.) cultivars, Erfordia and Wiselburger Kleinkornige, were tested at one location for 1 yr at three row spacings (15, 23 and 31 cm) and three seeding rates (100, 150 and 200 kg/ha). The effects of four seeding dates were evaluated for both cultivars. Seeding commenced on 2 May and was repeated at approximately 2-wk intervals. The narrowest row spacing produced the highest seed yield for both cultivars. Row spacing did not affect the protein content, but did affect the percent germination in the cultivar Kleinkornige. The narrowest row spacing (15 cm) produced the highest germination. Seed yield increased with seeding rate for the cultivar Kleinkornige. However, there was no increase in seed yield for the cultivar Erfordia when seeding rate increased from 150 to 200 kg/ha. Seeding rate did not affect the protein content or germination. Date of seeding had a significant effect on the yield. Delayed seeding significantly decreased the yield for both cultivars. Seeding date did not significantly affect the protein content of the seed. Germination was significantly reduced with delayed seeding.

Three faba bean cultivars, Aladin, Herz Freya and Outlook were seeded at three dates (25 Apr, 9 May and 23 May), and at four rates (50%, 75%, 100% and 125% of the recommended rate of 46 plants m−2) atone location (Winnipeg) for 2 yr (1983, 1984). Analysis of variance for yield indicated that both seeding date and seeding rate were very highly significant (P = 0.001). The early seeding date resulted in significantly higher yield and total dry matter and the greatest number of pods per plant. The 50% seeding rate resulted in significantly lower yield and total dry matter, but the highest seed weight and the greatest number of pods per plant, as well as the greatest number of days to maturity. The 75%, 100% and 125% seeding rates resulted in equivalent yield and total dry matter, but significantly fewer pods per plant and reduced seed weight as seeding rate increased. Increased seeding rate partially compensated for delayed seeding. Yield reductions of almost 1% a day for each day delay in seeding for the first 2-wk delay and almost 2% a day for each day delay in seeding for the second 2-wk delay were obtained in this study. It is concluded that seeding as early as possible at 75% of the present recommended seeding rate of 46 plants m−2 should maximize return on seeding cost to the grower.Key words: Total dry matter, harvest index, yield components, protein, density effects, faba bean

The results of three-year studies of the influence of seed sowing rates and sowing methods on the formation of yield capacity and quality of chickpea seeds are highlighted. The results of the research indicate a significant influence of the studied factors on the level of yield capacity of chickpea seeds. On average, for three years of research, the highest seed yield capacity in the experiment has been observed in the variety Odyssey – 2,16 t/ha. Among the studied variants of the sowing method, the highest rates of chickpea seed yield capacity have been provided by the row method with a row spacing of 30 cm (with a nutrition area of one plant of 120 cm2) at the average sowing rate of 0,7 million units/ha. In particular, the yield capacity of chickpea seeds of Budjak and Odyssey varieties under this combination of the studied factors made up 2,37 and 2,49 t/ha, respectively. The maximum protein content in chickpea seeds in both studied varieties has been obtained on the variants with a minimum seeding rate of 0,5 million units/ha, but the highest protein yield – 0,415 t/ha of Odyssey variety and 0,435 t/ha of Budjak variety - was noted on the variants with a seeding rate of 0,7 million units/ha.

Planting date (PD), seeding rate (SR), relative maturity (RM) of cultivars, and row spacing (RS) are primary management factors affecting soybean (Glycine max (L.) Merr.) yield. The individual and synergistic effects of PD, SR, RM, and RS on seed yield and agronomic characteristics in North Dakota were herein investigated. Early and late PD, early and late RM cultivars, two SR (408,000 and 457,000 seed ha−1), and two RS (30.5 and 61 cm) were evaluated in four total environments in 2019 and 2020. Maximizing green canopy cover prior to the beginning of flowering improved seed yield. Individual factors of early PD and narrow RS resulted in yield increase of 311 and 266 kg ha−1, respectively. The combined factors of early PD, late RM, high SR, and narrow RS improved yield by 26% and provided a $350 ha−1 partial profit over conventional practices. Canopy cover and yield had relatively weak relationships with r2 of 0.36, 0.23, 0.14, and 0.21 at the two trifoliolate, four trifoliolate, beginning of flowering, and beginning of pod formation soybean growth stages, respectively. Producers in the most northern soybean region of the USA should combine early planting, optimum RM cultivars, 457,000 seed ha−1 SR, and 31 cm RS to improve yield and profit compared to current management practices.

To compare the effects of varying seeding rate on the agronomic performance, phenology and seed quality of hybrid and conventional summer rape cultivars, four hybrid and two conventional summer rape cultivars were seeded at 1.5, 3.0, 4.5, 6.0 and 9.0 kg ha−1 at two locations for 3 yr. The hybrid cultivars were, very importantly, 24% higher yielding and produced 50% more total dry matter than the conventional cultivars. The hybrid cultivars were, on average, 1.3% lower in seed oil content, 1.0% higher in seed protein content and equal in sum of oil and protein in the seed compared with the conventional cultivars. The hybrid cultivars were on average, 1.3 d later to 50% flowering and 1.1 d later to maturity than the average for the conventional cultivars, (i.e., equal or earlier to flowering and maturity than Regent). The hybrid cultivars were also 3.9% lower in harvest index and 1.3 ppm lower in chlorophyll content than the conventional cultivars. In spite of these differences, there were no significant cultivar-by-seeding-rate interactions, indicating that the hybrid and conventional cultivars responded similarly to varying seeding rate. Lodging, days to 50% flowering, days to maturity, harvest index, survival, oil content and protein content displayed significant linear responses to varying seeding rate. Stand at maturity, seed yield and total dry matter production displayed significant linear and quadratic responses to varying seeding rate. Varying seeding rate had no effect on seed formation period, the sum of oil and protein content, or chlorophyll content. A seeding rate of 6 kg ha−1 maximized seed yield for both hybrid and conventional summer rape cultivars.Key words: Brassica napus, canola, seed quality, agronomy, phenology

A near-isogenic faba bean (Vicia faba L.) line, segregating in a 1:1 ratio of male-fertile to male-sterile plants, was used to study the importance of insect pollinators on ovule fertilization and yield components of the first five flowering nodes. The fertilization of ovules from open-pollinated plants at the higher insect pollinator site of Dijon, France was 83%, as compared with 50% at the lower insect pollinator activity site of Saskatoon, Canada. No significant differences in total fertilized ovules were found between male-fertile and male-sterile plants at Dijon, but male-fertile plants at Saskatoon had significantly more fertilized ovules than male-sterile plants. Seed production on the first five flowering nodes was significantly greater at Saskatoon. Thus, while insect pollinators are important in determining the potential yield of a faba bean plant, other factors, such as environment, determine the ultimate yield.Key words: Vicia faba, ovule fertilization, seed yield, faba bean, male sterility

The valorization of municipal solid waste (MSW) can serve as an organic amendment in agriculture while reducing solid waste accumulation in the environment. This research aimed to evaluate the valorization of a bio-stabilized MSW amendment for the production of faba bean (Vicia faba L.) crop. For this purpose, biomass production and growth, as well as, seed yield and seed components, seed nutrient accumulation, plant pigments, soil properties, and microorganisms were evaluated in comparison with faba bean mineral fertilization in a greenhouse experiment. The results demonstrated that the bio-stabilized MSW amendment achieved similar biomass production, plant growth, seed yield, nitrogen and protein content, and pigment content as the mineral fertilization treatment. On the other hand, the organic fertilization did not exhibit significant effects on the yield components number of pods per plant, and number of seeds per pod, and nutrient accumulation in seeds with respect to mineral and control treatments in both soils. Sandy and clay soil properties were improved in the organic treatments in comparison with the control soils by increasing soil organic carbon, nitrogen, and other soil nutrients, and providing a suitable pH for faba bean growth. Additionally, biological activity was favored by applying this source of organic fertilizer, enriching the nematode community. Reusing bio-stabilized MSW for agronomical purposes can add value to this waste product, serving as an effective alternative to mineral fertilizers in faba bean cultivation.

Effect On Yield

Background: In Tunisia, faba bean (Vicia faba L.) is the first major food legume. The development of faba bean production is facing several biotic constraints. Faba bean Ascochyta blight caused by Ascochyta fabae is one of the most destructive diseases of faba bean and can cause significant yield loss under favorable conditions. As only incomplete resistance ABL varieties are available, some agronomic practices should be applied to control and reduce Ascochyta blight incidence wherever possible. Therefore, this work was undertaken to evaluate the effect of spacing row and seed rate on ABL severity, growth and yield of faba bean. Methods: A split-plot design with three replications was adopted to carry out this study during 2018 and 2019 cropping seasons. ‘Bachaar’ faba bean variety was sown at 40 and 60 cm row spacing and at three seed rates (100, 140 and 200 kg ha-1). ABL severity was assessed visually on a 0-9 scale and agro-morphological traits were measured. Analysis of variance was used to analyze the data. Correlations between agronomic traits, row spacing, seed rate and ABL severity were investigated. Result: Results showed that seed rate has a larger effect on yield than row spacing. In both cropping seasons, the highest grain yield was recorded in 60 cm row spacing and 140 kg ha-1 seed rate treatment. So, this treatment is recommended for obtaining high yield of faba bean. Most of the variation in disease severity was associated with seed rate (r=0.62). The highest ABL score severity was noted at 200 kg ha-1 rate. Over both years, wide row spacing and low seed rate reduced ABL severity. In this study, the small amounts of ABL disease (which reached a score of 5.3 and 4.7 in 2018 and 2019, respectively) had little or no effect on yield.

The Impact

Little information is available on the management of turfgrass species for seed production in the Canadian prairies. The objective of these studies was to assess the impact of residue management and row spacing on seed yield under irrigation. A factorial experiment was seeded at Saskatoon, SK, in 1993 to assess the impact of burning or scalping (very close mowing with residue removal) vs. mowing, and 20- vs. 40-cm row spacing on seed yield of Kentucky bluegrass (KBG) (Poa pratensis), creeping red fescue (CRF) (Festuca rubra subsp. rubra) and creeping bentgrass (CBG) (Agrostis palustris). Also, a residue management trial on KBG was seeded at Brooks, AB, in 1993. At Saskatoon, yield was higher at 20-cm spacing across all three species in 1994, but spacing had no impact on winter survival, stand density, tiller growth or yield in subsequent years. Burning and scalping consistently resulted in earlier spring green-up, a higher proportion of fertile tillers, and higher seed yield than mowing. Even with residue management, yield declined after one harvest in CBG and CRF, and after two harvests in KBG. At Brooks, residue management had a similar impact on yield of KBG. A second trial at Brooks examined the impact of row spacing (20, 40, 60 cm) and seeding rate (0.5 to 6 kg seed ha-1) on KBG. Seed yield was highest at 40-cm spacings in 1994, at 60 cm in 1995, and at 40 to 60 cm in 1996. Seeding rate did not have a consistent effect on yield. We conclude that a combination of residue management and 20- to 40-cm spacings provide the highest, most consistent seed yields for these turfgrass species in this region.

Winter Wheat Yield

Field experiments were conducted in Oklahoma to determine the effects of winter wheat seeding date and cheat infestation level on cultural cheat control obtained by increasing winter wheat seeding rates and decreasing row spacing. Seeding rate and row spacing interactions influenced cheat density, biomass, or seed in harvested wheat (dockage) at two of three locations. Suppressive effects on cheat of increasing wheat seeding rates and reduced row spacings were greater in wheat seeded in September than later. At two other locations, increasing seeding rate from 67 to 101 kg ha–1or reducing row spacings from 22.5 to 15 cm increased winter wheat yield over a range of cheat infestation levels.
