Abstract: Purpose the objective of study to modified the metabolism of Calendula officinalis L. under heat stress couple with N and P application in two years of study. Methods the trail was conducted during peak summer season (months of May, June, and July) couple with different levels of N & P application to monitor the quality and quantity characterization of marigold (Calendula officinalis L.). The traits of three doses of N and P (0.6 g, 0.9 g, and 0.8 g, 1 − 1 g) given to Calendula officinalis L.) to display the vegetative, reproductive, physiological parameters such as Malondialdehyde (MDA), Chlorophyll contents, Lipid Peroxidation Assay in leaves, Li and K contents, phytochemicals and nitrogen and phosphorus used efficacy Results showed that maximum values of Malondialdehyde (MDA), Chlorophylls, Lipid Peroxidation Assay in leaves observed followed by the alteration in Li and K measured in the month of May, June with slight differences July. The phytochemicals like total phenolic contents (84.41 mg GAE/g), total antioxidants (36.3% DPPH), total carotenoids and total flavonoids contents (16.2 and 0.9 mg/100 g) were measured by 0.9 g of Nitrogen application and followed by 1 g of Phosphorus in both years of study. The respirational changes were observed in the higher rate of P levels. The liner changes of N and P rates showed some fluctuation in heat stress months. Conclusions It was concluded that the higher doses of both N and P fertilizers were effective in controlling the heat stress and mentioned the quality of florets by various induction and biological active process.
