SUMMARYSoya beans grown on land planted the previous year with inoculated soya beans produced more nodules, lodging, seed yield, 1000 seed weight, and protein content and less seed oil concentration as compared to those grown on land that was planted with non-inoculated soya beans. Nitrogen fertilization (120kg N/ha) reduced the total number of nodules per plant. Increasing inoculation rates of the seed increased the dry weight of nodules per plant. Location, nitrogen fertilization, and inoculation increased or decreased the levels of certain amino acids but had no significant effect on the sulphur amino acids, cystine and methionine.

Adequate nutrients for plants are important for increasing the yield and quality of the seeds produced. The objective of this study was to evaluate foliar fertilization with silicon in wheat and its effect on seed yield and physiological quality. Treatments consisted of two silicon dosages (three and six liters silicon per hectare) and the control (no silicon) and five wheat cultivars: OR "Quartzo", OR "Ônix", Fundacep "Linhagem", Fundacep "Campo Real" and Fundacep "Horizonte". The experimental design was randomized blocks with four replications. After physiological maturity, harvesting and threshing of the seeds were done manually. Seed samples were evaluated for yield and physiological quality from the germination test, first germination count, seedling dry weight, accelerated aging, electrical conductivity, 1000 seeds and hectoliter weights. The results showed that the foliar application of silicon at the dosages tested did not affect the yield and physiological quality of the seeds produced by the wheat cultivars.

Flax cultures give dual-purpose production – flax fibre and seeds. Flax varieties adapted to local climate conditions have breeded but up to now the profound research of its quality was not carried out. In our investigation we analysed flax varieties of Latvia selection for seed yield and quality in comparison with standard varieties ‘Vega 2’ and ‘Lirina’. In Latgale Agricultural Scientific Centre 10 Latvian flax varieties are cultivated and seed yield, 1000-seed weight, seed oil content (extracted by hot pressing method) and fatty acid content in flax seed oil (detected with gas chromatography method) have evaluated. Seed yields of fibre flax Latvian varieties are significantly higher in comparison with standard variety ‘Vega’. All analysed seed samples have high oil content (27- 47%) and there is high percentage of polyunsaturated fatty acids in oil (linoleic acid 10,6-16,9%, linolenic acid 54,7-62,1%). There is little difference in 1000-seed weight, content of oil in seeds, percentage of linoleic, linolenic, oleic, palmitic and stearic acid in oil between fibre flax and oil seed flax varieties. The difference between the varieties is more influential. Flaxes seeds from Latvian varieties are in high quality and can be used for food, medical and technical purposes.

Effect of Nitrogen Fertilization on Yield and Quality of EndiveThe aim of the experiments carried out in 2007-2008 was to assess the effect of various nitrogen doses on the growth, yield and nutritional value of two endive cultivars Cigal and Excel. The effects of two types of fertilizers were compared: that of ammonium nitrate with that of the product Entec-26. On the basis of the results obtained, it was shown that endive cv. Excel produced a marketable yield that was on average by 35.5% higher than that of the cultivar Cigal. A significantly higher marketable yield of endive was obtained by fertilizing with a single dose of the fertilizer Entec-26, particularly at the rates of 90 and 135 kg N·ha-1, and also 180 kg N·ha-1. The experiments also revealed a significant effect of the fertilization method and nitrogen application rate on the biological value of the endive cultivars under evaluation. The cultivar Excel was characterized by a higher degree of nitrate accumulation, whereas the cultivar Cigal had a higher vitamin C content, dry weight, and chlorophyll content.

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

An experiment was carried to find out the effect of sowing dates and cutting time on seed yield and quality of alfalfa cv. RL-88. The results of the experiment revealed that, the significantly higher seed yield per plant (1.491 g), seed yield per plot (161.07 g) and seed yield (355.00 kg ha-1) was noticed in 15th August sowing and the cutting carried out at 60 days after sowing. Whereas, the seed quality parameters of the resultant seeds viz., highest seed germination (95.00 %), seedling length (13.90 cm), seedling dry weight (412.69 mg) and seedling vigour index (1320) found highest in15th August sowing and the cutting followed at 60 days after sowing.

The influence of plant density on yield of three confectionery seed pumpkin accessions was investigated under non-irrigated field conditions. Seeds of Golden Delicious (GD), open-pollinated Chinese snow-white seed (CS), and a selection from Austrian hull-less (HL) pumpkin were planted 30, 60, and 90 cm apart in rows that were 127 cm apart with seedlings thinned to one plant per hill. Plants were grown from 23 May to 18 Sept. One fruit per plant was harvested from five plants for each of the three replications. The number of seeds (and dry weight of seed) per fruit were 242 (59 g), 304 (87 g), and 334 (106 g), respectively, at 30, 60, and 90 cm spacing for GD. The number of seeds (and dry weight of seed) per fruit were 219 (108 g), 266 (108 g), and 258 (106 g), respectively, at 30, 60, and 90 cm spacing for CS. The number of seeds (and dry weight of seed) per fruit were 376 (76 g), 404 (94 g), and 304 (82 g), respectively, at 30, 60, and 90 cm spacing for HL. Highest seed yield was at 60 cm plant spacing for CS and HL, whereas GD produced highest seed yield at 90 cm plant spacing. The differences in total seed yield, seed size, and confectionery seed quality, as influenced by plant density and seed source, were also characterized.

Objective of the research: to study the influence of the norms of mineral fertilizers on the yield and quality of seeds of oil flax varieties in the conditions of the northern forest-steppe of the Tyumen region. The studies were carried out on the experimental field of the State Agrarian University of the Northern Trans-Urals in 2019-2020. The soil of the experimental field is leached chernozem, thin, heavy loamy. Experimental options included: control, without fertilizers; NPK based on seed yield 2 t/ha; NPK based on seed yield of 3 t/ha. Increases in yield from the use of fertilizers in the studied varieties August and Sokol were obtained in 2019, the growing season of which was characterized by the amount of precipitation close to the long-term level. In 2020, when there was a shortage of precipitation, only the Sokol variety showed a positive reaction to fertilizers. Under the influence of fertilizers, the seed oil content of the August variety decreased, while the Sokol variety was at the same level in all variants.

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
