“…This increase in Pn might be due to the optimum availability of S during the early growth stages of sesame that might have improved the chlorophyll production and ratio between Rubisco and soluble protein in sesame plants. This result is similar to previously documented results, in which they reported that the S fertilization increases the chlorophyll content [43], photosynthesis rate [39] and maintains the balance between the ratio of Rubisco and soluble protein in oilseed crops [44]. Additionally, S fertilization to oilseed crops also decreases the uptake of toxic elements which are harmful to crops [45] The reason why the application of 40 kg S ha −1 (T 3 ) was adequate for Pn might be associated with the delayed leaf senescence (i.e., the longer leaf green area in V 3 ; Figure 4).…”

Oilseeds yield response to sulphur (S) has been well investigated but the dynamics of total biomass accumulation (TBA) and partitioning by sesame plants in response to S are not well understood. This study was initiated to investigate the effects of S on sesame, in which four sesame varieties V1, SG-27; V2, SG-30; V3, SG-36; V4, SG-51 and four S treatments T1, 20; T2, 30; T3, 40; T4, 50 kg ha−1 were used. Results revealed that the leaf area index and photosynthetic rate of sesame varieties were significantly higher under T3 with V3. Similarly, S fertilization considerably increased the TBA and maximum TBA was reached at late-flowering with V3 in T3. Relative to T1, plants in T3 had 33 and 23% higher capsule and seed biomass, respectively. Furthermore, total S accumulation and distribution in different plant organs changed with growth stage, at pre-flowering and mid-flowering stage maximum S was found in the stem, whereas at late-flowering and full-maturity stage highest S was recorded in reproductive parts. These results implied that S fertilizers should be applied to agricultural fields to improve oilseed production and by selecting the appropriate and area-specific genotype we can increase sesame seed yield under rainfed conditions.

“…Conversely, Subhani et al (2003) reports, that the oil content is directly proportional to the doses of sulphur. In further experiments, the most effective dosage of sulphur in regard to the yield and oil content was 40 kg.ha −1 (Rehman et al, 2013;Ahmad et al, 2011). In other experiments, the optimal dose of sulphur was 60 kg.ha −1 .…”

The aim of the experiment was to study the importance of sulphur in oilseed rape (Brassica napus L.) nutrition as well as the effect of rising doses of sulphur in combination with nitrogen on yield, oiliness, oil production, nutrients content in seed and nutrients uptake by rapeseed. The plot–scale experiment was established in years 2013/14 and 2014/15 within the agricultural cooperative in Mojmírovce. There were four fertilization treatments on 600 m2 experimental plots in three replications in this experiment. The first treatment was unfertilized control. Other three treatments were fertilized by the same nitrogen dose of 160 kg.ha−1 and by increasing doses of sulphur. The second treatment was fertilized by a dose of 15 kg.ha−1 S, the third by a dose of 40 kg.ha−1 and a dose of 65 kg.ha−1 S was applied at the fourth treatment. The highest average yield 3.96 t.ha-1 was found when a dose of 40 kg.ha−1 S was applied. The application of sulphur in a dose of 65 kg.ha−1 was accompanied by a yield decrease by 11.4 % as compared to the treatment where a sulphur dose of 40 kg.ha−1 was used. An average oil content of 45.1, 45.5, and 44.0 % was found in treatments in which the doses of sulphur of 15, 40 and 65 kg.ha−1 were applied. No significant difference among the treatments fertilized by sulphur was found. The average oil production reached 1809, 1802 and 1595 kg.ha−1 in cases of treatments fertilized by sulphur doses of 15, 40 and 65 kg.ha−1.

“…Rapeseed oil is ordinarily utilized in human diets on account of its great nutritional quality with a high proportion of unsaturated fatty acids and fair-minded fatty-acid composition (Rehman et al, 2013;Wang et al, 2014). After extraction, remaining rapeseed meal can be used as an organic fertilizer to the cropland or as a source of animal feed (Gao et al, 2010).…”

Winter rapeseed (Brassica napus L.) is a dominant oilseed crop and has become an alternate crop both for edible oil production and energy agriculture. This study was conducted to find out the response of nitrogen (N), phosphorus (P) and potassium (K) fertilizer combinations on yield, oil and protein contents in oilseed rape crop. Four fertilizer treatments of N, P and K fertilizers (NPK, NP, NK, and PK) were applied according to the local recommendations at three different sites in Hubei province, during the year 2012-2013. Rapeseed yield was significantly increased by 61-72% under NPK fertilization as compared to PK across study sites. Yield responses to fertilization were ranked as NPK>NP>NK>PK, illustrating that N was the most limiting nutrient in rapeseed productivity following P and K. Oil and protein yields were significantly affected to applied N, P, and K fertilizers. Among all combinations, NPK combination performed best. Oil and protein contents along with other fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid) were not influenced significantly by the application of P and K fertilizer. By increasing the amounts of N fertilizer application, oil contents of rapeseed reduced and protein contents increased consistently. These results suggest that NPK combination is more productive as compared to the other combinations.
