Sulphur Nutrition and its Effect on Yield and Oil Content of Oilseed Rape (Brassica Napus L.)

Abstract

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.

Enhancing the Yield and Quality of Oilseed Crops in Nepal Through Application of Sulphur Fertilizers

“…It was reported from the experiment that application of Sulphur at a dose of 60 kg s/ha, significantly affected on the content of glucosinolate and oil [19]. Whereas, similar report was founded by Walker and Booth (1994) that application of sulphur fertilizer ameliorate glucosinolate content in mustard seed [20]. The frequently irrigation in the field of oilseed crop proliferate the oil content significantly along with the application of Sulphur at 45 kg s/ha.…”

Content and yield of oil in spring rape seeds in conditions of nitrogen and sulphur fertilization

“…Oil content in rapeseeds is a stable, genetically determined characteristic (Rudko, 2011), but many studies confirm a modifying effect of agrotechnical factors on this trait (Rice, 2007;Malarz et al, 2011), among which sulphur application plays an important role (Sienkiewicz-Cholewa and Kieloch, 2015; Wielebski, 2015;Varényiová et al, 2017). The increased oil content observed following sulphur application is a consequence of increased content of CoA, which is a substrate for lipogenesis.…”

“…Many authors report a strong interaction between the level of nitrogen and sulphur on the oil yield of oilseed plants (Jamal et al, 2006;Tomar and Singh, 2007;Rudko, 2011;Varényiová et al, 2017). Fismes et al (2000) state that the interaction of nitrogen and sulphur is synergistic if the proportion of the two nutrients in the soil is optimal for a given species, but antagonistic if one of them is present in excess.…”

Acuities into tolerance mechanisms via different bioassay during Brassicaceae-Alternaria brassicicola interaction and its impact on yield

“…Brassica (Brassica napus, B. juncea and B. rapa) ranks second among oilseed crops after soybean [1]. The genus Brassica consists of members rich in nutritional and economical values [2].…”
