“…Drought stress is an important abiotic factor that limits oilseed rape production and yield, accounting for about 30% crop loss 3 4 . During drought stress, seed germination is assumed to be hampered, which results in poor crop stand, and inhibition of seedling growth 5 6 7 8 .…”

Effects of cold plasma treatment on seed germination, seedling growth, antioxidant enzymes, lipid peroxidation levels and osmotic-adjustment products of oilseed rape under drought stress were investigated in a drought-sensitive (Zhongshuang 7) and drought-tolerant cultivar (Zhongshuang 11). Results showed that, under drought stress, cold plasma treatment significantly improved the germination rate by 6.25% in Zhongshuang 7, and 4.44% in Zhongshuang 11. Seedling growth characteristics, including shoot and root dry weights, shoot and root lengths, and lateral root number, significantly increased after cold plasma treatment. The apparent contact angle was reduced by 30.38% in Zhongshuang 7 and 16.91% in Zhongshuang 11. Cold plasma treatment markedly raised superoxide dismutase and catalase activities by 17.71% and 16.52% in Zhongshuang 7, and by 13.00% and 13.21% in Zhongshuang 11. Moreover, cold plasma treatment significantly increased the soluble sugar and protein contents, but reduced the malondialdehyde content in seedlings. Our results suggested that cold plasma treatment improved oilseed rape drought tolerance by improving antioxidant enzyme activities, increasing osmotic-adjustment products, and reducing lipid peroxidation, especially in the drought-sensitive cultivar (Zhongshuang 7). Thus, cold plasma treatment can be used in an ameliorative way to improve germination and protect oilseed rape seedlings against damage caused by drought stress.

“…of the variation in seed yield in Germany can be explained by weather conditions during the individual stages of growth, of which the most important were the start of silique and seed formation (BBCH 50-65) and seed development (BBCH 71-79). Intensive research is currently being conducted on expanding oilseed rape cultivation in Turkey [16,19,20] and Iran [21][22][23][24][25]. Cultivation of sesame (Sesamum L.) and olive (Olea europea L.) was once dominant in these conditions, but more productive varieties of oilseed rape have become the main source of oil in the semiarid region.…”

“…However, such high water consumption itself limits the feasibility of such a measure in an arid zone. Jabbari et al [24] emphasize that where there is a water deficit in the soil, oilseed rape germination and seedling establishment are crucial stages for production, which are still poorly understood. In a pot experiment, when soil moisture content was decreased from 50% to 20% soil field capacity, total final emergence decreased from 94.3% to 82.7%.…”

Analysis of yield and plant traits of oilseed rape (Brassica napus L.) cultivated in temperate region in light of the possibilities of sowing in arid areas

et al. 2016

This work is a review of selected literature on the species of Brassica with the greatest economic significance. Oilseed rape (Brassica napus ssp. oleifera) currently ranks third worldwide among oilseed crops used for oil production and is the most important in the temperate zone. The manifold uses of rape include not only human consumption of oil, but also the use of post-extraction meal to feed livestock as well as industrial applications as a source of bioenergy or cellulose. The improvement in the economic position of rape among crop plants is also due to the doubling of its yield between 1970 and 2009; the average annual increase in seed yield worldwide was 27 kg ha−1 yr−1. The yield level in Europe exceeds the average yields achieved in the world, particularly in Asia. Recently, the cultivation of oilseed rape was started on a relatively large acreage in Iran where the yield amounted 2.1 t ha−1, exceeding the yields of China and India. In Poland, the acreage of oilseed rape cultivation between 1965 and 2013 increased 3–4 times, and during this period the annual increase in seed yield was 29 kg ha−1 yr−1. Under the field conditions of the temperate climate zone, winter oilseed rape yield is mainly determined by agro-climatic conditions during the growing period, the level of nitrogen fertilization, and the production potential of varieties, which is currently highest in hybrids. There is a noticeable tendency of hybrids towards formation of more siliques by individual oilseed plants. Different production categories of plants appear in a rape crop. Semi-dwarf varieties of winter rapeseed are distinguished by greater silique density, particularly on the main shoot. Moreover, these hybrids are characterized by faster growth of the root system, which enables them to take up nitrogen from the soil more efficiently.

“…Another potential problem is caused by excessive amounts of rain, resulting in paddy soil absorbing and retaining excessive amounts of moisture in the root zone of soil. Water is an important factor that affects the emergence of seedlings and early growth of crops (Devane 2009, Jabbari et al 2013. The growth and development of crops with shallow roots could be limited or even fail under such high soil moisture conditions; consequently, such crops are prone to root injury due to freezing or drought (Yun et al 2009).…”

Rice cropping areas have recently been restricted or reduced under the policy of the South Korean government. Therefore, the development of new crop or cropping systems is essential. Foxtail millet (Setaria italica.) is considered among the best candidate crops to substitute for rice, but there is limited information about maintaining or improving the grain yield without crop damage caused by excessive water content in sandy paddy fields. A two-year study from 2013 to 2014 was conducted in a trial field in the southern part of Korea (N 35˚ 05′ 16.8″, E 127˚ 56′ 34.6″). The three cultivars selected-Gyeongkwan 1, Samdachal, and Hwanggeumchal-are the most common varieties of foxtail millet in South Korea due to their highly functional nutrients and potential productivity. For the purpose of establishing the stable production of Foxtail millet in paddy-upland rotation fields, the effects of ridge width (60, 120 and 240 cm) on soil moisture in the ridge, and on the growth and yield of foxtail millet were investigated in a sandy paddy field. Soil water content increased in line with increasing ridge width. Therefore, the estimated retention time of excessive soil water during the cultivation period tended to increase in line with increasing ridge width. Foxtail millet plants reached the highest level of height in the 60-cm ridge width treatment in both years of the study. The grain yields in 2014 were 3.44, 3.77, and 3.28 tons˖ha -1 for Gyeongkwan 1, Samdachal, and Hwanggeumchal, respectively, grown in the 60-cm ridge width. The plant height and yield of foxtail millet had increased with a narrowed ridge width because soil-moisture conditions are remedied by ridge width. Therefore, we recommend that a ridge width of 60 cm be maintained to prevent excessive water damage to foxtail millet growth in a sandy paddy field.
