Abstract
Peanut, as an oilseed, have high nutritional value for humans and livestock and poultry. The seed yield (SY) of peanut decreases under drought stress conditions, and the zinc (Zn) nano-fertilizer can reduce the negative impacts of water deficiency on peanut plants and improves its SY. This experiment carried out as split plot based on randomized complete block design with three replications in Astara, Iran, during the 2018 and 2019 cropping seasons. Three irrigation regimes at 50 mm (IR50), 75 mm (IR75) and 100 mm (IR100) evaporation from class A evaporation pan in main plot and three levels of Zn nano-chelate, including 0.5 g. l−1; (Zn0.5), 1 g. l−1; (Zn1) and 1.5 g. l−1; (Zn1.5) in sub plot, comprised experimental treatments. The results indicated that the highest pod yield (PY), SY, oil yield (OY) and protein yield (PRY) of peanut (3633, 2900, 1582 and 826 kg. ha−1, respectively) were obtained in response to Zn nano-chelate with a dose of 1.0 g. l−1 in IR50 treatment. Nonetheless, under foliar spraying of Zn1 and severe drought stress conditions (IR100) were observed the highest proline (14.84 µmol g−1 FW), superoxide dismutase (53.42 Unit mg−1proteinmin−1), catalase (72.87 nmol mg−1proteinmin−1), peroxidase (64.17 nmol mg−1 protein min−1), soluble sugar content (172.04 mg g−1 FW), soluble protein content (114.16 mg g−1 DW) and anthocyanin pigments (11.20 µmol g−1 FW). Generally, application of Zn1 treatment, through increasing antioxidant enzymes activity and non-enzymatic antioxidants, improved peanut SY. Hence, foliar application of Zn nano-chelate could be recommended to enhance peanut yield.
