| Popis: | The experiment was conducted in one of the agricultural fields in the Diyala governorate to examine the impact of amino acid spraying at two concentrations (0,1 and 2 m L-1) on plant development and leaf N, P, K content. Soil was mulched with colorless and black plastic, and no mulching was used. White Snow F1 variety was used. SAS was used to run a statistical analysis, and a 0.05 significance level Duncan’s polynomial test was used to compare the means. Black mulching was found to be superior to other types of mulch in terms of the percentages of nitrogen, phosphorus, and potassium found in the leaves, as well as plant height, total leaves, leaf area, and relative chlorophyll content. Also the results showed a significant superiority of spraying with amino acids at a concentration of 2 m L-1 four sprays of plant height, number of leaves, leaf area, plant dry weight, relative chlorophyll content, as it gave. Interactions between the study’s two components also varied, as evidenced by the findings. The highest values for N, P, and K content in the leaves, plant height, number of leaves, leaf area, dry weight, and relative chlorophyll content were all obtained when black mulching was combined with spraying with amino acids at a concentration of 2 m L-1 four times. This resulted in values of 73.00 cm, 24.00 leaf-1, 271.94 cm2 plant-1, 3.33 cm, and 69.00 SPAD. |
