(Investigation of the improvement in morphological and biochemical properties of soybean plants treated with hydroxyapatite nanoparticles)

Our work amid to synthesis nano-hydroxyapatite (HANPs) and nano hydroxyapatite hybrid loaded urea (NHANPs) using chemical precipitation reaction technique to create a novel design of recent soil fertilizers able to maximize availability of plant nutrients for uptake by plants while minimizing their loss through leaching or surface runoff in the soil called slow-release. To examine those nano-fertilizers, design a pot test turned into performed for the duration of the summer season 2021 on soybean plants growth. The pot test blanketed 16 treatments which have been mixtures of three factors. The first factor was (HANPs) with soil addition for four concentrations, i.e. 250 kg fed–1 (Monocalcium phosphate as positive control), 50 kg (HANPs) fed–1, 25 kg (HANPs) fed–1 and 12.5 kg (HANPs) fed–1. The second factor was (NHANPs) with soil addition for four concentrations, i.e. 150 kg fed–1 (Ammonium sulphate as positive control), 50 kg (NHANPs) fed–1, 25 kg (NHANPs) fed–1, and 12.5 kg (NHANPs) fed–1. Data reflected a significant upgrade in all growth traits studied. Treatment (25 kg HANPs+25 kg NHANPs) and treatment (12.5 kg HANPs+12.5 kg NHANPs) surpassed all positive control treatments in root and shoot fresh weight and number of leaves each plant which reflect the great result of these chemical substances. In conclusion, the combined application of nano fertilizers might be recommended to maximize soybean growth and productivity
