Sulphur fertilization enhanced yield, its uptake, use efficiency and economic returns of Aloe vera L.

Abstract

Sulphur plays a vital role in the formation and biosynthesis of protein, chlorophyll, and few amino acids. To investigate the effect of sulphur fertilizer on leaf biomass yield, critical sulphur concentration, sulphur requirement and uptake by Aloe vera L., a pot experiment was carried out following completely randomized design with six levels of sulphur viz., 0, 15, 30, 45, 60 and 80 kg ha −1 with three replications. The results of the study revealed that the growth attributes, leaf and gel yield, and sulphur uptake significantly improved with sulphur application and the best results were obtained from the application of 45 kg sulphur ha −1 . On average, addition of sulphur enhanced the leaf biomass yield by 47.5% and sulphur use efficiency by 38% compared to control. The effect of sulphur on the growth parameters and their significant and positive correlations with yield signifies the importance of sulphur on the yield and quality of A. vera . The calculated minimum amount of sulphur for 80% leaf biomass production was 21.1 kg sulphur ha −1 with a critical leaf sulphur concentration of 0.23% in A. vera. Moreover, sulphur addition to soil substantially enhanced the economic returns of A. vera . Therefore, addition of 45 kg sulphur ha −1 could be a better option for obtaining higher yield and economic return of A. vera .

Sulfate-Based Fertilizers Regulate Nutrient Uptake, Photosynthetic Gas Exchange, and Enzymatic Antioxidants to Increase Sunflower Growth and Yield Under Drought Stress

“…The beneficial effects of gypsum application on chloroplast health were evident by the increased SPAD value, which helped to maintain chlorophyll, and inhibited the destruction of photosynthetic pigments under extreme conditions (Al-Huqail et al 2017). These findings suggest that the use of (Chowdhury et al 2020). Drought-mediated stomatal closure significantly reduced the photosynthetic rate (A), transpiration (E), and stomatal conductance (g s ) of sunflower plants (Fig.…”

“…The application of SO 4 2− based inorganic fertilizers has gained special attention in the past few decades due to increased deficiency of S in agricultural soils. In plants, S deficiency decreases chlorophyll and Rubisco content and induces chlorosis in young leaves (Muneer et al 2014;Chowdhury et al 2020). On the contrary, the availability of S promotes the biosynthesis of proteins and chlorophyll (Fatma et al 2014), regulates antioxidant enzymes (Usmani et al 2020), and enhances the activity of photosynthetic apparatus under challenging environmental conditions including drought (Lee et al 2016).…”

The Role of the Start-Up Aid for Young Farmers in the Adoption of Innovative Agricultural Activities: The Case of Aloe Vera

“…A number of studies also explore the effect of the harvesting period [66][67][68][69] on the yield and in the concentration of bioactive compounds. Finally, several studies estimate the effect of various inorganic fertilizers as well as organic manures on the yield and the quality of the aloe vera gel [58,[70][71][72][73].…”

Combined Sulfur and Nitrogen Foliar Application Increases Extra Virgin Olive Oil Quantity without Affecting Its Nutritional Quality

“…It has been reported by several authors that the supply of sulfur (S) can increase the lipid content in seeds of different cultivars such as rape, canola, and mustard, as well as change the ratio of fatty acids, thereby improving the oil quality [3,[7][8][9]. Sulfur is the fourth major plant nutrient after nitrogen (N), phosphorus (P), and potassium (K), and it plays a crucial role in plant growth and development [10]. It participates in many biochemical reactions, and it is a key factor in the synthesis of four sulfur-containing amino acids, methionine, cysteine, homocysteine, and taurine, of which only the first two are incorporated into proteins [11].…”
