The use of technologies is increasingly present in agriculture. The seed coating is one of these technologies. However, to obtain it, it’s demanded the use of machines and technics which are restricted to production companies, burdening the price on this type of product. Given the above, it was aimed to develop and evaluate a prototype capable of coating small seeds. To elaborate the conceptual design of the prototype it was employed the computer program for modeling 3D SketchUp, version 2014. The prototype measures were expressed in millimeters (mm). The prototype has three main parts: (1) support base, (2) seed coating bowl, and (3) cementing material container. To evaluate the prototype, bentonite, gypsum and kaolin were used as filling materials of the colza seed (Brassica napus L.). As cementing material the PVA glue was used in the percentages of 20, 30, 40 and 50%. The studied variables were prototype yield, production cost of the coated seeds and residue generated in the coating process. The prototype has a compact size, answering the needs of laboratory and/or small producer. It presented cost and residues in an acceptable level and yield up to 88%.

Rape (Brassica napus L. var. napus) is long ago-known vegetable of Brassicaceae in agriculture. It is important and valuable oil, forage, green-fertiliser and nectar plant. The experience of last years shows that rape is suitable for growing in conditions of Latvia, but investigations about its cultivars and growing technologies are not wide enough.The phosporus-fertilizer adding in the rape plantations is of great importance for increasing of its productivity. With the aim to reduce the expenses the phosphorus treated rape seeds are made use.In our investigations the velocity of seeds germination, germinating viability, germinating vigour, green pigments” quantity in seed-lobes and seeds” corp are studied. The conclusion is drawn that phosphorus treated seeds are of elevated physiological activity and elevated quantity of chlorophyll in seed-lobes, the seed-corp is increased for 3-70%. The velocity of the seeds” germination, germinating ability and germinat ing viability is increased too.The making use of phosphorus treated seeds is of great effectiveness because it gives the possibility to prevent phosphorus-lack in plants and to increase physiological activity and productivity of plants.

Seeding Date

The time interval for planting fall-seeded Brassica napus L. canola in the Northern Great Plains is narrow, since seeding must occur as close to soil freeze-up as possible to minimize the risk of winter kill. The Prairie ecoregion tends to have more stable fall and winter temperatures than the Rocky Mountain foothill region, where fall and winter chinooks may initiate germination and increase the risk of winter mortality. Our objectives were to determine an optimum seeding date interval for fall-seeded canola and whether a water-impervious polymer seed coating could advance the seeding date and reduce the risk of stand loss and corresponding yield reduction in two distinct agroecoregions. A range of fall seeding dates and a water-impervious polymer seed coating vs. a control treatment (water-soluble film) were assessed at 14 sites (five locations) from 1998 to 2001 in Alberta and Saskatchewan (Prairie sites) and at six sites (four locations 1999–2001) in Montana, USA (Foothill sites). Highest seedling densities and canola yield responses for the control treatment were attained in the first 2 wk of November in the Prairie sites, while responses to seed date were much more variable in the Foothill region. In the Prairie sites, the water-impervious polymer seed coating improved seedling density and seed yield as seeding date was progressively moved forward from the first week of November to the first week of October. The benefit of the water-impervious polymer seed coating became notable when soil temperatures were above 5°C. The water-impervious polymer coating provided only marginal improvement in plant stand and canola yield in the Foothill region. In the Foothill region and at Lethbridge, fall-seeded canola densities were on average 60% lower than spring-seeded canola densities and fall seeding increased canola yield in only one site-year when compared with spring-seeded canola. In the Prairie region, a water-impervious polymer coating can broaden the time interval for fall seeding; however, it does not ensure that recommended densities of spring seedlings will be attained. The optimum seeding date for fall seeding in the Foothill region could not be adequately defined for either the control or the water-impervious polymer coated seed due to the variable nature of the late fall and winter weather.

Early Fall

Polymer seed coatings offer an opportunity to fall seed Brassica napus earlier in October, thus avoiding difficult seeding conditions (wet/frozen soils) common in late October or early November. A multi-year field experiment was conducted at four locations in Alberta, Canada, to investigate the effect of early (mid-October) and late fall (late October-early November) canola seeding with and without a germination-inhibiting polymer seed coat. Yield and yield components were determined in glufosinate (hybrid and open-pollinated), glyphosate (open-pollinated), and imidazolinone (open-pollinated) herbicidetolerant canola cultivars. Early-seeded canola without the polymer coat had a reduced plant density of 58% compared to late-fall-seeded canola. Application of the polymer coat on early-seeded canola increased plant density by 80% compared to uncoated seed. Seed yield and dockage were not affected by seeding date when a polymer seed coating was used. Without the polymer seed coat, canola yield was reduced 42% and dockage increased 6% when seeding occurred in early vs. late fall. Increased pod production from early-fall-seeded uncoated canola compared to other seeding dates could only partially compensate for canola yield. Cultivar interactions generally were not agronomically important. The use of polymer seed coatings with all these herbicide-tolerant cultivars will allow producers to seed earlier in fall, rather than waiting for cooler soil conditions in late fall.

Отмечена роль Н. И. Вавилова в организации исследований исходного и селекционного материала по биохимическим признакам, определяющим пищевые, кормовые и технологические качества сельскохозяйственной продукции. Выделен перспективный материал для создания сортов рапса с улучшенными пищевыми, кормовыми и технологическими характеристиками; выявлен характер зависимости признаков качества масла от погодных условий (температура, количество осадков и др.). Изучены 50 высокоэруковых (ВЭ) и 40 низкоэруковых (НЭ) линий ярового рапса (Brassica napus L.), выращенных в условиях Ленинградской области в 2012 – 2015 гг. Содержание масла и влажность в семенах определяли методом инфракрасной спектрометрии. Жирнокислотный состав (ЖКС) масла изучали с помощью газожидкостной хроматографии с масс-спектрометрией. Установлено содержание доминирующих жирных кислот для ВЭ и НЭ образцов, а также характер влияния погодных условий на ЖКС масла, в том числе на состав его отдельных фракций. Для ВЭ образцов установлена достоверная отрицательная корреляция (r = –0,96) между содержанием эруковой кислоты и температурой воздуха и достоверная положительная (r = 0,96) с количеством осадков в первую декаду июля. Для НЭ образцов установлена достоверная отрицательная зависимость между содержанием эруковой кислоты и средней температурой воздуха в мае. Выделенные образцы с высоким содержанием олеиновой (61,4 %) и низким линолевой (7,4 %) кислот можно рекомендовать для получения безэруковых сортов рапса, масло которых пригодно для длительного хранения. Контрастные по содержанию эруковой кислоты образцы будут использованы для создания сортов ярового рапса пищевого и кормового назначения, а также для производства биодизеля.
