Title : Biosynthesis of Sulfur nanoparticles from tea (Camellia sinensis) waste and its effects on plant growth promotion
Nanobiotechnology has established a significant contribution in recent days toward sustainable agriculture by increasing crop yields and enhancing the quality of the soil. It also has specific purposes like nanobiofertilizers, plant growth promotors, and nanobiostimulants that improve productivity without contaminating soils. It also helps in bioremediation, protecting plants from pests and various biological illnesses. In recent research, nanobiostimulants has very different and unique properties compared to chemical fertilizers. Recently, farmers have been searching for cost-effective alternatives and have better efficiency of fertilizers to increase their overall yield with less environmental effect. So, there is various research in nanobiotechnology, which can be an alternative to chemical fertilizers and replace chemical pesticides. Sulfur is necessary for the growth and development of plants like any other nutrient. Sulfur is also one of the crucial nutrients that are required for plant growth. It plays an essential role in chlorophyll formation, allowing plants to generate carbohydrates, sugars, vitamins, oils, fats, and other components through photosynthesis. So, sulfur gained some importance in this work that we performed. The sulphur NPs have certain nutrient content, which increases the absorption duration and will help extend nutrient availability for plants for an extended time. Applying sulphur NPs to plants will help improve yield and increase nutrients. Sulfur nanoparticles were biosynthesized using a suitable precursor. The tea dust waste has been used to prepare a tea extract, this tea extract act as a balancing agent in SNPs synthesis. To understand the working efficiency of Sulphur NPs in plants by observing the physiological and morphological traits of fenugreek plants by application of green synthesized sulphur nanoparticles at different concentrations in Petri plate study and further studied with an effective concentration in pot study.
