Effect of Multinutrients Loaded Electrospun PVA Nanofibre on Germination and its Growth Parameters of Green Gram [Vigna radiata (L.) Wilczek]

Background: In the present study, redundant blanket applications of chemical fertilizer application to the soil set foot into the aquatic environment and cause eutrophication. Besides it cause low nutrient efficiencies, low organic matter, imbalanced fertilization and low fertilizer response influence to decrease crop yield. To solve this serious problem localized delivery of multi nutrients loaded with electrospun nanofibre through the seed coating approach. The nanofibre regulates the nutrient release at the targeted site (rhizospheric zone) in a sustained pattern of using e-spin technology. Methods: The electrospun carrier was developed from PVA at 10%, diameter of fibre ranges form (260 nm to 540 nm) was used as nanocarrier for encapsulate the multi nutrient at different concentration of 25, 50, 75, 100%. A field experiment was conducted during 2019-2020, to study the impact of crop response of MNC loaded nanofibre coated green gram seed. Result: It conclude that the novel nanofibre technology improve the higher plant height (47.38 cm) at maturity stage, total leaf area (1093.95), net assimilation rate (2.92 mg cm(-2) day(-1)) at flowering stage, seed yield (883.41 kg ha(-1)) as compared to absolute control approaches. This nanofibre technology will give novel idea for the fertilizer industry owing to its unique larger surface area and controlled release kinetics.
