Abstract:
The present test was conducted to assess the influence of spraying Pars Humic on the flowering performance and nutrient element concentration of Iranian borage (Echium amoenum Fisch & Mey) in 2020 in a farm located in Roudbarsara village, Rezvanshahr County. The experiment was conducted on random blocks with three iterations. Treatments included Pars Humic (65% humic, and 5% nitrogen) at three levels including a1:H0 (control), a2:H1 (2 per 1,000), and a3:H2 (4 per 1,000) and a3:H3 (6 per 1,000). The traits of plant height, biomass yield, number of branches, flower yield, and flower potassium, phosphorus, calcium, and magnesium contents were evaluated in this experiment. Spraying humic acid in this experiment was revealed to have a significant impact on the studied traits, indicating that the application of Pars Humic at various doses left significant impacts on said traits. The greatest plant height, number of branches, and biomass yield were observed in treatment H1 (0.002 Pars Humic) and the lowest impact was observed in the 0.006 Pars Humic treatment. Humic acid at the H1 level (0.002 Pars Humic) improved the performance of flower components in borage due to better nutrient absorption. The greatest flower field was obtained through spraying the 0.002 Pars Humic treatment which indicated a 13% improvement compared to the control treatment (no spraying). Increasing the Pars Humic content of the treatment from 0.002 to 0.006 reduced flower yield, and the greatest decline was observed in treatment H3 (0.006 Pars Humic). Comparison of means of the data at various levels of Pars Humic consumption indicated that the greatest phosphorus and potassium contents in flowers were obtained from the H1 treatment (0.002 Pars Humic), and the highest calcium and magnesium content in flowers were obtained from the H2 treatment (0.004 Pars Humic). Meanwhile, Pars Humic treatment was revealed to have a significant and positive influence on plant height, flower yield, biomass yield, the number of branches, and the studied elements. Eventually, improving the absorption of nutrients and developing the reproductive and vegetative components increased flower yield. The highest impact of Pars Humic treatment on Iranian borage was associated with 2 liters of Pars Humic per 1,000 liters of water.
