The inappropriate use of phosphorus and nitrogen fertilizers has caused irreversible damage to plant growth and productivity. The designed Ur@HANP has shown positive effects on rice seed germination and growth, providing a more efficient and non-toxic alternative to conventional fertilizers.
Inappropriate use of phosphorus and nitrogen fertilizers has imposed irreparable damage to plant growth and productivity. Urea doped hydroxyapatite nanoparticles (Ur@HANP) was designed for controlled-release formulation for crop improvement. The main objective of the present work was to synthesize and evaluate the functioning of Ur@HANP on rice seed germination and transport of nano-nutrients in soil media. HANP was synthesized using sol-gel technique and urea was loaded into it for monitoring rice seeds' physiological and biochemical activities under controlled laboratory condition. Seedling growth (5.99217 +/- 0.156), fresh weight (13.8 +/- 0.5) and dry weight (1.6 +/- 0.5) were enhanced in Ur@HANP treatment compared to control. Both HANP and Ur@HANP was also tested in sand columns and agricultural soil to understand the retention capacity of plant nutrients in sand and interaction with soil colloids, where Ur@HANP showed almost twofold efficiency than conventional P and N fertilizers. Even at a higher dose of 1 M, it did not impart any kind of toxicity symptoms. Almost twofold increase in alpha-amylase and starch content in Ur@HANP could be the reason for such response. We anticipate Ur@HANP could be a suitable alternative for N and P fertilizers in the development of eco-friendly sustainable agriculture.
