Abstract:
Kentwood white bean (Phaseolus vulgaris L.) was sown at three seeding rates in narrow rows for 4 yr With direct-harvesting, yields increased as seeding rates increased up to 64 seeds m−2, whereas, with hand-harvesting seed yield was not affected. Seed quality was superior in the direct-harvested plots; however, yield was lower. Seed size was not affected.Key words: White bean, narrow-row, yield, seed quality

Abstract:
Seeding rate and row spacing are management practices that affect flax seed yield. Two experiments were conducted from 1988 to 1990 to determine the influence of flax seeding rates (300, 600, and 900 seeds m−2) and row spacings (9, 18, and 27 cm). One was a flax-weed interference study (three sites) and the other was a weed-free study (13 sites). In the presence of weeds, increasing seeding rate from 300 to 900 seeds m−2 improved flax seed yield by 180 kg ha−1, and reduced broadleaf weed yields by 300 kg ha−1 and grassy weed yields by 180 kg ha−1.

Row spacing at a constant seed rate did not affect yield. With increasing seed rate there was an increase in yield, mainly through more heads per unit area, which more than compensated for a decrease in seeds per head. Nar

Poppy cultivation has a long tradition in Central Europe. Growing winter poppy instead of the commonly grown spring poppy might increase seed yield, especially in the face of changing climatic conditions. However, knowledge regarding optimum sowing date and optimum sowing rate for winter poppy under Pannonian climate conditions in Central Europe is missing. Therefore, a two-year field experiment was performed in Eastern Austria with four sowing dates ranging from early September to mid/end of October and two sowing rates with 50 or 100 mg seeds m−2.

Abstract:
Maximizing productivity and profitability are the primary reasons for double-cropping soybean with small grain in the Mid-Atlantic, USA. Reduced double-crop yield can be attributed to: delayed planting that results in a shortened growing season and less vegetative growth; later-maturing cultivars that terminate main stem growth after flowering and have less growth and nodes; less soil moisture and plant-available nutrients due to small grain uptake; greater air and soil temperatures during vegetative stages that reduce early-season growth; and more favorable conditions for disease development

Although projected terrestrial CO2 levels will not reach 1000 μmol moI-1 (0.1%) for many decades, CO2 levels in growth chambers and greenhouses routinely exceed that concentration. CO2 levels in life support systems in space can exceed 10,000 μmol moI-1 (1%) CO2. Numerous studies have examined CO2 effects up to 1000 μmol mol-1, but theoretical and some experimental evidence indicates that the beneficial effects of CO2 continue past 1000 μmol mol-1 and are near-optimal for wheat at about 1200 μmol mol-1.

Abstract Lentil (Lens culinaris L. Medik.) is an important cool-season food legume but is a poor competitor to weeds because of a slow early growth rate. If weeds are left uncontrolled, they can reduce yield by up to 50%. Sensitivity of lentil to post-emergence herbicides warrants development of herbicide-tolerant cultivars. In the absence of natural variability, mutation breeding is a powerful tool to create variability for desired traits. Thus, 1000 seeds of a lentil genotype, LL1203, were exposed to gamma radiation (300 Gy, <sup>60</sup>Co) with the objective to induce herbicide tolerance.

Above a threshold spacing, the pH-pH2S acceptability domains are smaller as the austenite spacing increases.

In the conditions of the Penza region in 2021–2022 developed elements of the technology of a new variety of awnless brome Udalets when cultivated for seed purposes. We studied the sowing method (factor A) — a row at 15 cm (control) and a wide-row method with row spacings of 30 cm, 45 cm, 60 cm, as well as seeding rates (75; 90; 105; 120 plants per linear meter). According to the hydrothermal coefficient, the growing season of 2021 was characterized as dry (hydrothermal coefficient is equal to 0.8), 2022 — normal in terms of moisture supply (hydrothermal coefficient is equal to 1.0).

Abstract:
Soybean [Glycine max (L.) Merr.] is a leading supplier of vegetable oil and high-quality protein meal in world markets. Processors expect an oil yield of at least 11 lb bu-1 and want to produce a 48% protein meal. On-farm soybean yields show a linear increase of ~0.45 bu a-1 yr-1, but the prevalent negative association between yield and seed protein concentration resulted in a decrease in seed protein of ~2 percentage points during the past 80 years. Seed oil concentration typically is slightly positively associated with yield and highly negatively correlated with protein, and estimates for th

Dense white mustard (Sinapis alba L.) can suppress weeds, however excessive density negatively influences crop yields. The search for the optimal parameters for applying mineral fertilizers and the consumption of seed material will increase the crop yield and will improve its competitive ability. This work aimed to identify the seeding rate and doses of nitrogen fertilization at which white mustard plants can actively suppress weeds without reducing the productivity of the crop. In the course of this research, we established that S. alba sown at a rate of 2, 2.5 and 3 million seeds per ha supp

The aim of the research was to determine the effect of the highly concentrated fertilizer “Vuksal Boron” on the yield and quality of spring rape seeds. The surveys were carried out on the variety ‘Galant’ in the central zone of the Krasnodar Territory. As a result of two year trials, we found that 5–10 l/ha of “Vuksal Boron” positively affected the yield and seed quality of rapeseed. The yield increase was 2.4-3.6 kg/ha or 9–11 % compared to control; the crude fat content in rape seeds was 1.6–2.7%.

Abstract:
Environmental, developmental, physiological and biochemical determinants of cucurbit seed quality were investigated in field and laboratory experiments. The major factor influencing seed quality is seed maturity at harvest, with both immature and overmature seeds exhibiting reduced quality. Planting density and fruit load per plant can be manipulated to maximize seed yield per unit area without adversely affecting seed quality. Seeds harvested at optimal maturity will have the greatest germination vigor and will maintain quality longer during storage. Seed priming can improve germination rates

Porphyra species (commonly known as ‘nori’ or ‘purple laver’) are edible red seaweeds rich in proteins, vitamins and other highly valued biogenic compounds. For years Porphyra has been cultured using seeded nets extended in the open sea, and its biomass consumed primarily in the Far East. While demands for international markets have increased steadily at an average of 20% per year, supplies are on the verge and not expected to meet future demands. Alternatively, land-based cultivation of seaweed has become attractive in the mariculture industry since (1) important growth parameters can be cont

Abstract:
Pod-filling, an important yield-determining stage is strongly influenced by water stress. This is particularly true for peanut (Arachishypogaea), wherein pods are developed underground and are directly affected by the water condition. Pod-filling in peanut has a significant genetic component as well, since genotypes are considerably varied in their pod-fill (PF) and seed-fill (SF) potential. The goals of this research were to: Examine the effects of genotype, irrigation, and genotype X irrigation on PF and SF. Detect global changes in mRNA and metabolites levels that accompany PF and SF.
