Effects of sulphur on the yield, yield component characters and oil content of oilseed rape

Abstract

The effects of four sulphur levels: S0, S1, S2 and S3, including 0, 12, 24 and 36 kg S ha-1, respectively, along with 115 kg N ha-1 were studied on yield-related traits of oilseed rape (Brassica napus L.). The significant variance of treatments was determined for plant height, yield component characters, seed yield and oil content. The sulphur application significantly increased most of the traits compared to the S0 level. The S3 (36 kg S ha-1) treatment led to the highest mean value of plant height (132 cm) which was classified with S2 (24 kg S ha-1) in the same statistical group. Sulphur had an increasing effect on pods per plant, and it ranged from 92 to 196 for S0 and S3 applications, respectively. S0 and S1 with 92 and 121 pods per plant were grouped in the same statistical group. In addition, S2, and S3 with 165 and 196 pods per plant showed no significant statistical difference. The sulphur application significantly increased seed yield compared to control (S0 level), and it ranged from 2744 to 3215 kg ha-1 in S0 and S3, respectively. The average oil contents of 45.69, 46.96, 47.46 and 49.53 % were detected for 0, 12, 24 and 36 kg S ha-1, respectively.

Effect of Sulfur, Boron, Zinc and Iron on Canola under Salt Affected Soils

“…In addition to these results may be due to the importance of sulfur for chlorophyll production where it has a vital role in cell division aided leaf growth and improved light absorption. (Rameeh et al 2021). Also, it promotes releasing nutrients Iron is an important nutrient for cell metabolism, chlorophyll production, photosynthesis, respiration and enzymes activity (Riki et al 2014).…”

“…The application of sulfur is vital for methionine and cysteine (a vitamin A component) synthesis, enhances some enzymes in the plant and chlorophyll synthesis (Waraich et al 2022). Also, it increases oil concentration in canola seeds as well as glycosylate content (Rameeh et al 2021). On the other hand, sulfur application significantly decreases soil pH which respectively improve nutrients availability in soil, enhance nutrients uptake by plant and finally improve yield productivity of plant (Abou Hussien et al 2020).…”

Combination Effects of Sulfur Fertilizer and Rhizobium Inoculant on Photosynthesis Dynamics and Yield Components of Soybean

“…It makes some contributions to protein synthesis by orchestrating the folding and structural stability of a protein [6]. Some research showed the positive effect of sulfur on the yield of oil seed crops, such as groundnut [7], rapeseed [8], mustard [9], sesame [10], sunflower [11], and soybean [12,13]. Several field studies have demonstrated that the application of sulfur in conjunction with nitrogen in soybean fields has resulted in a significant increase in seed yield.…”
