| dc.description.abstract | Nano hydroxyapatite was formulated from eggshell using standard methodology and characterized by DLS and scanning electron microscopy (SEM). The characterisation results proved the nanoscale size of synthesized hydroxyapatite. The efficacy of nano hydroxyapatite along with nano rock phosphate was assessed on wheat seed germination and seedling growth indices. The experiment was conducted under laboratory condition with 5 treatments including nano hydroxyapatite and nano rock phosphate at 50 and 100 ppm along with control (water soaking). Experiment was conducted in completely randomized block design with 4 replications. To find out the optimum concentration of nano hydroxyapatite and nano rock phosphate, experiments were conducted under pot condition with 3 doses of fertilizers (RDF, 50% RDF and control) and 4 concentrations of nanoparticles spray (0, 150, 300 and 450 ppm). Experiments were conducted in completely randomized block design with 3 replications. To assess the efficacy of nano hydroxyapatite and nano rock phosphate on wheat field experiments were conducted with 9 treatments viz; RDF, RDF + spray of nano hydroxyapatite (nHA)/nano rock phosphate (nRP) at 30 DAS, RDF + spray of nHA/nRP at 30 and 60 DAS, 50% RDF, 50% RDF + spray of nHA/nRP at 30 DAS and 50% RDF + spray of nHA/nRP at 30 and 60 DAS, Control, Control + spray of nHA/nRP at 30 DAS, Control + spray of nHA/nRP at 30 and 60 DAS. Experiments were conducted in randomized block design with 3 replications. Laboratory experiment revealed that wheat seed treatment either with nano hydroxyapatite or nano RP at 100 ppm improved the seedling growth parameters and seedling growth vigour of wheat. However, the germination percentage was not affected significantly due to the nanopatricles seed treatment. The results of pot experiment revealed that spray of nano hydroxyapatite and nano RP gives the highest plant height and tillers/pot when applied at the rate of 300 ppm. The field experiment results of the both the experiments on nano hydroxyapatite and nano RP revealed that RDF+ spray of nano hydroxyapatite at 30 and 60 DAS and RDF + sprays of nano RP at 30 and 60 DAS reported better growth parameters, growth indices, physiological parameters, yield attributes, yield, nutrient uptake, nutrient use efficiency and economic return. While comparing the nano hydroxyapatite and nano RP, nano hydroxyapatite recordedbetter growth parameters, growth indices, physiological parameters, yield attributes, yield, nutrient uptake and nutrient use efficiency. While both the nanoparticles remain significantly at par with each other. RDF+ sprays of nano hydroxyapatite at 30 and 60 DAS proved the best nutrient management tool for wheat in term of productivity, nutrient use efficiency and economic return. | en_US |
