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. Key words: chickpeas, seeding rate, sowing method, yield capacity, protein content.

Goal. To substantiate the technology of growing fennel in Lisste. Crop accounting was performed by continuous submerged threshing. Methods. The yield was brought to 100% purity and standard humidity according to the method described by V.O. Moiseychenko and V.O. Yeshchenko. Mathematical data processing was performed according to the method of B.A. Dopehova. Results. The article highlights the results of studies of technological factors influence (sowing time, seeding rates, row spacing, growth regulators and terms of their application) on the yield and quality of fennel seeds when grown in the Western Forest-Steppe. Indicators of yield and content of essential oil in seeds depending on the studied factors are given. According to the research results, on average over the years of research the yield of fennel seeds at 1.56 t / ha was obtained by sowing at the level of thermal regime of the soil 6–80C in a wide row at 45 cm by seeding rate of one million sprouting seeds per hectare. Among the studied agents Vermiyodis was the best when used for seed treatment, and the agent Humifield – for the treatment of vegetative plants, the yield on these variants exceeded the control by: 0.28 and 0.30 t / ha, respectively. The maximum content of essential oil in the same variants of experiments was determined. In addition, calculations have been made which show that the maximum conditional oil yield of 60 kg / ha was observed in the variant of sowing in the first term with a row spacing of 45 cm and the sowing rate of one million sprouting seeds per hectare. The use of growth regulators helped to increase the conditional yield of essential oil by 4.5–11.6 kg / ha. Conclusions. Тo ensure the yield of fennel seeds at the level of 1.56-1.8 t / ha, the content of essential oil in the seeds - in the range of 6.26-6.36% in the Western Forest-Steppe, we offer sowing at the level of soil thermal regime 6-80C in a wide row at 45 cm sowing rate of one million such seeds per hectare, in the phase of plant stems - spraying crops growth regulator Humifield at the rate of 100 g / ha, dissolved in 250 liters of water.

Two large-seeded buckwheat (Fagopyrum esculentum Moench.) cultivars, Mancan and Manor, and semi-dwarf lines, were grown at Morden and Portage la Prairie in the years 1979–1982 at seeding rates of 15, 30, 45 and 60 kg/ha. There was no consistent effect of seeding rate on plant height, seed weight (g/1000 seeds) or seed density. In six of the eight location-years there was no interaction of genotype × seeding rate for seed yield, indicating that, generally, the cultivars and lines reacted similarly to differences in seeding rate. It was concluded that a seeding rate of from 30 to 45 kg/ha would ensure optimum yield in most years.Key words: Buckwheat, Fagopyrum esculentum Moench., seeding rates

Pan, X., Caldwell, C. D., Falk, K. C. and Lada, R. 2012. The effect of cultivar, seeding rate and applied nitrogen on Brassica carinata seed yield and quality in contrasting environments. Can. J. Plant Sci. 92: 961–971. The unremitting growth of oilseed demand makes it necessary to explore alternative oilseed crops to meet this requirement. This study evaluated the effects of genotype, seeding rate and nitrogen (N) supply on the seed yield and quality of oilseed Brassica carinata A. Braun in three contrasting environments (Truro, NS, Harrington, PE and Saskatoon, SK). Useful genetic variation in agronomic and seed quality characteristics was found among these 10 B. carinata genotypes and genotype selection requires location specific recommendation. Line 050488EM had consistently good yield in both Nova Scotia and Prince Edward Island, while line 070768EM displayed better yield stability across 2 yr in Saskatchewan. Because of the high degree of compensatory ability to low plant population, maximum seed yield of B. carinata can be achieved over the range from 34 to 114 plants m−2. No significant difference in oil and protein content of seed due to seeding rates was observed. The linear increase in seed and oil yield with increased N rate up to 150 kg ha−1 indicates that B. carinata is highly responsive to applied N. Increases in N supply resulted in a decrease in oil content and a corresponding increase in protein content in all experiments. In summary, the findings of this study provide convincing evidence of the agronomic adaptation of B. carinata to all three locations.

Glaucous Altai wildrye grass, Leymus angustus (Trin.) Pilger, has been reported to exhibit higher seed yield than the normal green phenotype. Seed quality is correlated with successful seedling establishment. Our objective was to determine the seed yield and quality of three half-sib populations of Altai wildrye that differed in visible glaucousness. Seed was harvested from 60 glaucous, 60 non-glaucous, and 60 variably glaucous half-sib lines over 3 yr at a semi-arid location. Seed yield, seed weight and germination was greater from glaucous lines than the nonglaucous lines. Key words: Glaucous, range improvement, seedling establishment, epicuticular wax

The experiment consisted of three single row spacings (every 25, 40 and 50 cm) and four double and triple row spacings (40-25-40 cm, 40-25-25-40 cm, 50-25-50 cm, 50-25-25- 50 cm). The aim of the present experiment was to compare the influence of varying spacing on yields and quality of chamomile seeds. Among the row spacings under comparison, the highest seed and herb yields were achieved from the triple row spacing. 1000-seed weight was proportional to seed yield, and the seed germination capacity was not differentiated due to row spacings used. Plants growing in single rows every 25 cm formed the lowest number of branches terminated by flower heads, thus the herb and seed yields were the lowest.

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.

Selection Of

The results of scientific research are presented, which made it possible to develop less labor-intensive methods for selecting flax plants to grow original (updated) seeds. Studies have shown that a positive selection of tall plants of flax, compared with the accepted counterpart (control), increased seed yield 1.7-1.9 times. Moreover, plant homogeneity according to the main characteristics (height and fiber content in the stem) characterizing the varietal quality of grown seeds turned out to be at the control level. A negative selection, involving the removal of atypical plants, provided an increase in the output volume of seeds compared to the control by 3.9-4.1 times. This selection method did not reduce the varietal quality of seed material compared to the accepted analogue. With both selection methods, after combining typical plants, seeds with the same high germination rates were obtained (96-99 %). The breeding efficiency of the grown flax seeds using narrow-row sowing methods is shown. Studies have established that narrow-row sowing of seeds with a row-spacing of 7.5 and 6.25 cm compared with sowing by a wide-row method significantly increased their yield by 2.8-3.0 and 2.3-3.0 kg / ha, respectively. The greatest influence on the formation of seed yield in narrow-row sowing (6.25 cm) was exerted by the method of sowing, the part of which was 76.1 %. As the length of seed propagation of flax in creased (up to the uterine elite 2 years) in narrow-row sowing (6.25 cm) compared to broad-row, there was no decrease in quality indicators - germination and seed strength.
