Tomato is an important vegetable that highly sensitive to drought (DR) stress which impairs the development of tomato seedlings. Recently, melatonin (ME) has emerged as a nontoxic, regulatory biomolecule regulates plant growth and enhances DR tolerance mechanism in plants. The present study was conducted examine defensive role ME photosynthesis, root architecture, antioxidant enzymes' activities seedlings subjected stress. Our results indicated strongly suppressed biomass production, inhibited negatively affected morphology, reduced photosynthetic pigments Per contra, soluble sugars, proline, ROS (reactive oxygen species) were suggested be improved under Conversely, (100 µM) pretreatment detrimental-effect by restoring chlorophyll content, gas exchange parameters attributes compared with DR-group only. Moreover, supplementation also mitigated enzymes [APX (ascorbate peroxidase), CAT (catalase), DHAR (dehydroascorbate reductase), GST (glutathione S-transferase), GR MDHAR (monodehydroascorbate POD (peroxidase), SOD (superoxide dismutase)], non-enzymatic [AsA (ascorbate), DHA (dehydroascorbic acid), GSH (glutathione), GSSG, (oxidized glutathione)] activities, oxidative damage [EL (electrolyte leakage), H2O2 (hydrogen peroxide), MDA (malondialdehyde), O2•- ion)] osmoregulation (soluble sugars proline) seedlings, regulating gene expression for SOD, CAT, APX, GR, POD, GST, DHAR, MDHAR.

Although nitrogen (N) is the most limiting nutrient for agricultural production, its overuse associated with environmental pollution, increased concentration of greenhouse gases, and several human animal health implications. These implications are greatly affected by biochemical transformations losses N such as volatilization, leaching, runoff, denitrification. Half globally produced fertilizers used to grow three major cereals—rice, wheat, maize—and their current level recovery approximately 30–50%. The continuously increasing application fertilizers, despite lower cereals, can further intensify leftover N. To address these implications, improvement in use efficiency (NUE) adopting efficient agronomic practices modern breeding biotechnological tools developing cultivars requires immediate attention. Conventional marker-assisted selection methods be map quantitative trait loci, introgression elite germplasm leads creation better NUE.
