“…It is therefore necessary to constantly improve grain yield per unit area to maintain food security (Peng et al, 2006 ). Oilseed rape ( Brassica napus L.) is globally the second most significant source of edible oil; it has high nutritional value and a favorable composition of fatty acids for both human consumption and livestock feed (Foley et al, 2011 ; Yousaf et al, in press ). Therefore, its demand is increasing considerably all over the world (Kim et al, 2013 ).…”

The use of efficient rates of nitrogen (N) fertilizer application is important with regard to increasing crop productivity and maintaining environmental sustainability. Rice-oilseed rape rotations are a mainstay of the economy and food security of China. Therefore, a field experiment was carried out during 2011–2013 in Honghu to identify the most appropriate N application rates for enhancing crop productivity and N use efficiency for rice (Oryza sativa L.)-oilseed rape (Brassica napus L.) rotations. Six N fertilizer treatments (RO1, RO2, RO3, RO4, RO5, and RO6) were laid out in a randomized complete block design with three replicates. ROx represented the N fertilizer application rates (kg ha−1) for rice and oilseed rape, respectively. Grain yields from plots receiving N fertilizer were significantly increased by 59–71% (rice) and 109–160% (oilseed rape) during the total rotation (2011–2013), as compared to RO1 (control; no application). Furthermore, a similar trend was observed for N accumulation, ranging from 88 to 125% and 134 to 200% in aerial parts of rice and oilseed rape, respectively. Nitrogen use efficiency (NUE) was significantly higher (38.5%) under RO2 and lower (34.2%) under RO6 while apparent N balance (ANB) was positively lowest under R05 (183.4 kg ha−1) followed by R02 (234.2 kg ha−1) and highest under R06 (344.5 kg ha−1) during the total rotation. The results of grain yield, NUE, and ANB indicated that the R02 rate of N application was superior. This information should help to develop a cost-effective and environment-friendly N management strategy for rice-oilseed rape rotation systems of central China.

“…In contrast, very limited information is available on the Evening Primrose response to the P and K application [22] and no information is available under field conditions. In contrast, other species with similar uses, e.g., rapeseed, showed a strong response to N and to a lesser extent, to P and K [23], the latter of which showed little effects on the seed oil composition. In addition, rapeseed P and K accumulation may also depend on the S availability [24].…”

Evening Primrose (Oenothera biennis L.) is an industrial crop-producing seed with high oil concentration characterized by high gamma-linoleic acid. However, limited information is available on its response to the nutrient supply, especially P and K. The aim of this work was to compare the response of Evening Primrose to the application of N, P, and K alone or in combination in a P and K deficient soil in terms of grain yield, yield components, and oil composition in comparison to Rapeseed (Brassica napus L.). Evening Primrose yielded 54.4% less seed and 67.3% less oil than Rapeseed. Such differences were reduced when nutrients, especially N or P, were applied. N stimulated Evening Primrose more than Rapeseed. Application of K favored Evening Primrose oil yield when no N or P were added, and this especially occurred by an enhancement of the pod number. P favored yield per pod and oil yield in the Evening Primrose more than Rapeseed in almost all conditions. Fertilization scarcely affected lipid composition. In particular, an increase in the oleic acid concentration was found only when N + K or N + P + K were applied compared to the sole N or sole K applications. These results suggest that P and K differentially influenced yield components of both species and that Evening Primrose was less adapted than Rapeseed to a scarce nutrient supply.

“…According to Akdemir et al [42], seed crude protein in canola is approximately 16 to 24%. Nitrogen fertilizer application increased the protein contents but decreased the oil contents of rape seed; however, these parameters were not significantly influenced by the application of P and K fertilizer [49]. According to Lucas et al [50], N and S fertilization increased canola yield without significantly altering the content of oil and crude protein.…”

Introduction:Canola is an important agricultural crop generally grown for oil and biofuel generation.Materials and Methods:The agroindustrial solid wastes of oregano and cumin wastes were used in a vegetation experiment to determine their effect on the nutrition, yield and quality of the canola plant (Brassica napusL.) The experiment was performed on 12 plots of 6 m2and was conducted with four treatments of composted oregano and cumin wastes, mineral fertilization and control in three replications. Physical and chemical properties and macro-micro nutrients were determined in the soils at the beginning and the end of the experiment.Results and Discussion:The leaves showed sufficient levels of N, P, K, Ca, Mg and low sufficient levels of Na, Fe, Cu, Zn and Mn. The boron content of the leaves was insufficient. Manganese and B were affected significantly by the applications. The applications did not affect plant height, shoot and carob number per plant, and seed numbers per carob significantly. Statistically, the highest number of plants per m2was observed in the plots to which cumin wastes were applied, and these plots also showed the maximum yield.Conclusion:Seed yield, protein and oil percentages were not affected significantly by the applications.
