The objective of this study was to determine parameters of crambe oil culvtived with phosphorus (P), with respect to oil content, fatty acid composition, minor compounds, and total antioxidant activity. The experiment followed a randomized block design, with five doses of P (0, 40, 80, 120, and 160 kg P ha−1) and four replications. All results were subjected to analysis of covariance (ANCOVA) 5% significance. The P dose had a negative linear association with δ‐tocopherol and total antioxidant activity, and a positive association with stigmasterol and total carotenoids. P influenced the concentrations of β‐sitosterol and campesterol, whereas the remaining variables (content, α‐tocopherol, β + γ‐tocopherol, fatty acids, total phenolic compounds, and chlorophyll a) were not affected. This study show a positive effect the concentrations of compounds that act as antioxidants in crambe oil, which can influence with its oxidation stability. Practical applications: Is relevant the studies concerning the oxidative stability of inedible vegetable oils, such as crambe, in terms of the composition of antioxidants and fatty acids, as this affects the conservation, storage and refining costs, and the quality of the products, considering the many uses of this oil, such as biodiesel, lubricants, corrosion inhibitors, synthetic rubber, plastic films, nylon, and adhesives, among other products. Phosphorus (P) plays an important role in synthesis processes performed by plants such as, functions in cell energy transfer, respiration, and photosynthesis, with an emphasis on processes related to the flow of energy and products stored in grains. In this study, P influenced on the concentrations of compounds such phytosterols and carotenoids, which shows a positive effect in concentrations of compounds that act as antioxidants in crambe oil.

The dependence on non-renewable fuels of countries around the world increased the interest for the gradual replacement of fossil fuels with renewable ones. Thus, several development programs for the use of renewable sources for power generation have been created and, in this perspective, biofuels have been highlighted. Crambe is an alternative crop for the production of biodiesel due to its rusticity, precocity, high oil content and adaptability to different climates. Optimum management practices of fertilizer use in crambe cultivation are little known and there are no specific recommendations for its fertilization. Therefore, the objective of this research was to study the effects of mineral fertilizers concerning the nitrogen and potassium elements in the growth and production of crambe. The experiment was installed in a greenhouse, with a completely randomized design. Nitrogen doses used were 30, 60, 90 and 120 kg•ha −1 and 50, 75, 100 to 125 kg•ha −1 for potassium. The increase in production was directly proportional to the increase in nitrogen levels. The potassium doses did not cause significant effect on the growth of crambe.

“…Average crambe yields range from 0.6-1.6 (Budzyński and Jankowski, 1999;dos Santos et al, 2013;Rogério et al, 2013) to 2.5 Mg ha À1 (Falasca et al, 2010). The oil content of crambe seeds is 300-430 g kg À1 DM (Zadernowski et al, 1999;Machado et al, 2007;Falasca et al, 2010;Lalas et al, 2012).…”

Crambe seeds have numerous industrial applications. Crambe seed oil contains mostly monounsaturated fatty acids. Seeds contain crude protein, amino acid, glucosinolates. They are used in human and animal nutrition. The aim of this study was to determine the physical and chemical properties of crambe seeds subjected to fertilization at 0, 15, 30 kg S ha−1. Thousand seed weight ranged from 6.93 g (0S) to 8.04 g (30S). All results were statistically significantly different. Length (L) of seeds ranged from 2.20 mm (0S, 15S) to 2.24 mm (30S), width (S) ranged from 1.90 mm (0S) to 1.95 mm (30S), surface area (F) ranged from 3.53 mm2 (0S) to 3.67 mm2 (30S). All samples (0S, 15S, 30S) formed one homogenous group for the values of L, S, F. Crude fat content was 349.8 g kg−1 DM (0S) to 377.9 g kg−1 DM (30S) and crude protein content was 241.0 g kg−1 DM (0S) to 250.3 g kg−1 DM (30S). The results for each sample were statistically significantly different. The results can be used in practice to determine the dose of sulfur fertilizer. Fertilization caused changes in 1000 seed weight of crambe. Additionally, selected linear dimensions and shape factors of crambe seeds were affected by fertilizer. Sulfur fertilization caused changes in the crude fat and crude protein content of crambe seeds.
