“…Oil content in the seeds ranges between 38% and 53% by weight [75,[78][79][80][81]. Sunflower is commonly considered an "environmental friendly" crop [82]; indeed, it generally requires low level of fertilization and the row spacing of about 50 cm allows for mechanical control of weeds [82]. On the other hand, ploughing resulted in being helpful to ensure the correct development of the tap root [83].…”

Herbaceous Oil Crops, a Review on Mechanical Harvesting State of the Art

The sustainable production of renewable energy is a key topic on the European community’s agenda in the next decades. The use of residuals from agriculture could not be enough to meet the growing demand for energy, and the contribution of vegetable oil to biodiesel production may be important. Moreover, vegetable oil can surrogate petroleum products in many cases, as in cosmetics, biopolymers, or lubricants production. However, the cultivation of oil crops for the mere production of industrial oil would arise concerns on competition for land use between food and non-food crops. Additionally, the economic sustainability is not always guaranteed, since the mechanical harvesting, in some cases, is still far from acceptable. Therefore, it is difficult to plan the future strategy on bioproducts production from oil crops if the actual feasibility to harvest the seeds is still almost unknown. With the present review, the authors aim to provide a comprehensive overview on the state of the art of mechanical harvesting in seven herbaceous oil crops, namely: sunflower (Heliantus annuus L.), canola (Brassica napus L.), cardoon (Cynara cardunculus L.), camelina (Camelina sativa (L.) Crantz), safflower (Carthamus tinctorius L.), crambe (Crambe abyssinica R. E. Fr.), and castor bean (Ricinus communis L.). The review underlines that the mechanical harvesting of sunflower, canola and cardoon seeds is performed relying on specific devices that perform effectively with a minimum seed loss. Crambe and safflower seeds can be harvested through a combine harvester equipped with a header for cereals. On the other hand, camelina and castor crops still lack the reliable implementation on combine harvesters. Some attempts have been performed to harvest camelina and castor while using a cereal header and a maize header, respectively, but the actual effectiveness of both strategies is still unknown.

“…Soilborne pathogens can coexist in the soil (Raaijmakers et al, 2009), and their heterogeneous distribution makes monitoring them costly and usually ineffective (Matthiessen and Kirkegaard, 2006). For many oilseed diseases, genetic resistance is one of the most effective protection methods, but it breaks down frequently due to the appearance of new virulent strains, as observed for sunflower diseases (Vear, 2016;Debaeke et al, 2017b;Molinero-Ruiz, 2019). To reduce the pressure of soilborne pathogens, farmers used to fumigate vegetable and ornamental crops intensively with methyl bromide (Hoffmann and Malkomes, 1974;Duniway, 2002;Martin, 2003).…”

“…At least 30 sunflower diseases are known. The most damaging and widespread fungal diseases are downy mildew (Plasmopara halstedii), phoma black stem (Phoma macdonaldii), phomopsis stem canker (Phomopsis helianthi), white mold (Sclerotinia sclerotiorum) and Verticillium wilt (Verticillium dahliae) (Seassau, 2010;Vear, 2016;Debaeke et al, 2017b), most of which are soilborne pathogens (P. halstedii, S. sclerotiorum, V. dahliae). More recently, Cadophora malorum has been reported as a new soilborne fungus of sunflower (Martín-Sanz et al, 2018;Molinero-Ruiz, 2019).…”

Sunflower (Helianthus annuus L.) is one of the three most productive oilseed crops worldwide. Soilborne diseases limit yields and are challenging to manage. The fungi Verticillium dahliae, Sclerotinia sclerotiorum and Macrophomina phaseolina can survive in the soil for many years and spread. Following the ban on fumigants, biofumigation, which consists of growing, chopping and incorporating a Brassicaceae cover crop to allow biocidal compounds production in the soil, may be an alternative. Biocidal effects of the hydrolysis of glucosinolate into active compounds, such as isothiocyanates, have been shown in laboratory studies, but the effectiveness of biofumigation varies more in the field. The present study reviews the main factors that determine effective biofumigation to protect sunflower. Since the toxicity of isothiocyanates to pathogens varies widely among the latter, we reviewed studies that assessed the suppressive effect of products of glucosinolate hydrolysis on V. dahliae, S. sclerotiorum and M. phaseolina. Farmers can use many mechanisms to increase isothiocyanate production, which may protect sunflower crop effectively. Increasing biomass production and chopping the cover crop during mild temperatures and before rainy periods could increase biofumigation effectiveness. Further field experiments are needed to confirm the potential of biofumigation to control soilborne diseases of sunflower and assess potential disservices to beneficial soil communities, given their potential key role in the control of soilborne pathogens.

Abiotic Stress in Plants

The food demand is increasing hastily, that is inducing continuous pressure on agriculture sector and industries to fulfill rising dietary needs. To meet with increasing demand, the food production must be elevated up to 70% until the year 2050. On the other hand, changing climate is disturbing crop production around the World. Crops grown under field conditions are affected by more than one abiotic stress. It is continuous task and challenge for agronomists to make crops environment hardy to obtain maximum yield. It is considered that different agronomic managements, if done appropriately, could be beneficial for increasing crop production. The optimal provision of plant nutrients can assist the crops to fight in better way with environmental stress like drought; it can help them to continue their normal metabolism even under hostile abiotic circumstances. The regions that have reduced availability of water for crop production, a balanced nutrient management can assist crops to give adequate production. Some of nutrients have potential of not only maintaining plant metabolism but also to enhance the quality of product. This chapter highlights the protagonist of plant nutrients in alleviation of drought stress in field crops.
