“…Some negative consequences of abiotic stresses are inevitable, but select management or breeding (Mansoori et al, 2017) strategies, such as the use of drought-resistant genotypes, adjustment of crop sowing date (Gul and Ahmad, 2007), use of mulch materials, adjusted irrigation (Gul and Ahmad, 2004), adjusted fertilization (Ahmad et al, 2007;Ebrahimian et al, 2017), and other agronomic methods (CCC, 2017b), may ensure higher productivity in canola. For example, deficit irrigation that omits watering at the flowering and seed-ripening stages will cause the greatest reductions in grain and oil yield, so if water via irrigation is to be limited, then this should not occur at these stages (Istanbulluoglu et al, 2010). The exogenous application to soil of some osmoprotectants or compatible solutes with organic amendments and essential nutrients may provide an economically viable and environmentally sound management strategy for sustainable canola production under abiotic stress in arid and semi-arid environments.…”

“…Reduced leaf chl content in response to water stress is caused by ROS production, which damages the chloroplasts (Gill and Tuteja, 2010). The ultimate effect of water deficit on canola is a reduction in plant height, number of branches, pod length, grain size (1000-grain weight) and yield and thus a deterioration of product quality, i.e., reduced oil yield by about 40% (Istanbulluoglu et al, 2010). Canola is most sensitive to water stress during the flowering stage and least sensitive during the vegetative and seed-filling stages, with the former resulting in crop maturation 127 days early, reduced water use efficiency, seed and oil yield, and oil content (Tesfamariam et al, 2010).…”

The oil of canola (Brassica napus L.), a globally important major oilseed crop, is used for salads, frying, the development of margarines, shortenings, and other food products. However, the growth and yield of canola are mainly restricted by drought and salinity, which can become acute in climate change. The exogenous application of some antioxidants has been shown to enhance tolerance to drought and salinity in select plants. Therefore, a thorough understanding of the effect of drought and salinity stress is crucial for understanding their adverse effect on canola cultivation and to establish useful strategies to maximize oil productivity. Given the economic importance of this crop, we reviewed studies within the extensive canola literature to assess the adverse effects of abiotic stresses, with a special emphasis on drought, water deficit and salinity, and how these stresses impact its growth and productivity in a bid to determine the role that antioxidants might play in alleviating the adverse effects of environmental stresses. This review notes how the productivity of canola tends to decrease under different abiotic stresses due to their adverse effect on morphological, physiological and biochemical processes, including lowered or reduced leaf area, leaf relative water content, stability of cell membranes, photosynthetic capacity, stomatal conductance, damage to chlorophyll and the production of reactive oxygen species. In addition, this review also discusses management strategies that would allow researchers or farmers to mitigate salinity and drought stress by using compatible solutes, nutrient management or other means to maximize canola yield. The application of antioxidants to soil, in combination with essential nutrients, alongside other management strategies, may assist in alleviating the harmful effects of environmental stresses in canola production.

Water resources in the North China Plain (NCP) are limited, so it’s in urgent need to optimize deficit by irrigation for sustainable winter wheat production in this area. Winter wheat grain yield (GY), contribution of dry matter (DM) remobilization to GY (CDMRG), and water use efficiency (WUE) were investigated in NCP. Compared with non-irrigation treatment, irrigated with 60 mm each at the winter wheat jointing stage (JS) and heading stage (HS) achieved reasonable winter wheat GY and WUE. Compared with irrigation with 120 mm only at JS and irrigation with 40 mm each at JS, HS, and milking stage (MS) of winter wheat, irrigation with 60 mm each at JS and HS provided the highest CDMRG, which resulted to the highest GY and WUE; this result was mainly due to a significant increase of the spike numbers (SN) per m2. The results suggest that in the NCP, in order to achieve reasonable GY and WUE, winter wheat should be irrigated with 60 mm each at JS and HS.

Do Soil Warming and Changes in Precipitation Patterns Affect Seed Yield and Seed Quality of Field-Grown Winter Oilseed Rape?

et al. 2020

Increasing air and soil temperatures and changes in precipitation patterns as consequences of climate change will affect crop production in agricultural ecosystems. The combined effects of soil warming and altered precipitation on the productivity and product quality of oil crops are not yet well studied. Winter oilseed rape (OSR) (Brassica napus L., cv. Mercedes) was field-grown under elevated soil temperature (+2.5 °C), reduced precipitation amount (−25%), reduced precipitation frequency (−50%) both separately and in combination in order to investigate effects on crop development, seed yield, and seed quality. Soil warming accelerated crop development during early plant growth and during spring. At maturity, however, plants in all treatments were similar in quantitative (aboveground biomass, seed yield) and qualitative (protein and oil content, amino acids, fatty acids) parameters. We observed the long-term effects of the precipitation manipulation on leaf size, leaf senescence and biomass allocation. Seed yield was not affected by the altered climatic factors, perhaps due to adaptation of soil microorganisms to permanent soil warming and to relatively wet conditions during the seed-filling period. Overall, OSR performed well under moderate changes in soil temperature and precipitation patterns; thus, we observed stable seed yield without negative impacts on nutritive seed quality.
