Linear Decline

The sustainability of cereal cropping systems may be improved by the addition of legumes. The effects of seeding rate were studied for intercrops of berseem clover (Trifolium alexandrinum L.) and oats (Avena sativa L.). Bigbee berseem clover, an annual forage legume, was intercropped with oats on a Black Chernozemic soil at Edmonton, Alberta, in 1996 and 1997. Berseem dry matter (DM) yields were greatly reduced by increasing oat plant density. There was a linear decline in berseem DM with increasing oat DM or oat tiller density. The relationship between oat plant density and berseem DM was nonlinear and varied between years and harvests. Berseem yield reductions varied from 44 to 82% with target densities of 100 oat plants m-2. Effects of berseem seeding rate (BSR) on oats varied between years. Increasing BSR from 6 to 24 kg ha-1 decreased oat tillering, oat DM and oat plant DM by 22–51, 0–57 and 8–51%, respectively, and increased oat tiller DM by 0–18%, with oats at 10 to 20 plants m-2. Differences between years were likely due to environmental factors and relative emergence times. After a silage-stage harvest, oat regrowth was negligible but berseem regrowth averaged 3.1 Mg ha-1 DM.

The results of studies on the influence of agrotechnological techniques on the productivity of alfalfa (Medicago sativa), cultivation on agro-peat soils in the south of Belarus were presented. It was established that the yield of green mass on average over 4 years of life was 393.6–517.9 c / ha when sown under cover and 494.3–629.8 centners ha-1 with coverless sowing. Productivity — 56.5–75.1 and 69.5–89.7 centners ha-1, respectively. A positive correlation between the increase in the yield and productivity of the grass stand with an rise in the seeding rate and doses of fertilizers applied was noted.

Analysis of the height and leafiness of plants of oats (fodder), pea (spring), field pea was carried out depending on the seeding rates and fertilization. It was established that under the increase in the seeding rate of oats by 25 %, the height of plants of the grass and legume components rose irrespectively of the rate of fertilization. The leafiness of leguminous crops was 2.9—3.1 times higher than that of oats.

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.
