Abstract
Due to the increasing environmental and economic challenges, there is an urgent need to conduct research into areas that will contribute to creating new strategies that improve the efficiency of the agricultural sector and maintain sustainability. Currently, carbon nanoparticles (CNP) have emerged as a promising technology for enhancing the effectiveness of amino acids and other bioactive compounds. So, afield research work was executed aiming to evaluate the response of garlic plant to the foliar application of the studied natural amino acids and carbon nanoparticles synthesized from glucose and selected amino acids under 9 treatments [T1: Control (tap water), T2: β-Alanine (at rate of 80 mg L-1), T3: Citrulline (at rate of 80 mg L-1), T4: Proline (at rate of 80 mg L-1), T5: Taurine (at rate of 80 mg L-1), T6: β-Alanine CNP (at rate of 80 mg L-1), T7: Citrulline CNP (at rate of 80 mg L-1), T8: Proline CNP (at rate of 80 mg L-1), T9: Taurine CNP (at rate of 80 mg L-1)] under completely randomized design. All treatments of natural amino acids and carbon nanoparticles synthesized from glucose and selected amino acids significantly increased the values of all studied traits related with growth criteria (e.g., leaves fresh and dry weights and leaf area), photosynthetic pigments (e.g., Chlorophyll a & b), leaf nutritional status (e.g., nitrogen, phosphorus and potassium), bulb yield (e.g., No. of cloves bulb-1,bulb yield and marketable yield ) and bulb quality (e.g., carbohydrates, total dissolved solid , dry mater and vitamin C). All CNP treatments outperformed the natural amino acid treatments. Regarding the natural amino acid treatments, the superior amino acid was taurine followed by proline then citrulline and lately β-Alanine. Concerning the CNP treatments, the superior treatment was taurine CNP followed by proline CNP then citrulline CNP and lately β-Alanine CNP. For example, the increasing rate in the marketable yield values due to the studied treatments compared to control treatment was 5.02, 8.21, 13.47, 16.89, 22.14, 26.48, 30.13 and 34.70 % with T2, T3, T4, T5, T6, T7, T8 and T9, respectively. Overall, it can be concluded that the sustainability of agriculture can be improved by applying the carbon nanoparticles (CNP) in the agricultural sector.
