Abstract
Soil salinity stress is considered one of the most damaging abiotic stresses that worsen under climate change particularly in arid and semi-arid regions, limiting plant productivity and reducing several crop yields. The current study was conducted in an open field under abiotic (saline soil) and biotic stress (early blight disease caused by Alternaria solani) to evaluate the protective effects of selected nutrients (i.e., B, K, and Se), and H2O2 on potato crop. Foliar applied H2O2 alone or with a combination with studied nutrients was effective in mitigating the adverse effects of studied stresses on growth and yield of potato. Foliar application of H2O2 + K promoted the vegetative growth parameters, chlorophyll content by more than 50% compared to the control, whereas this treatment led to increase by 116, and 35.4% in total tuber weight and marketable tuber yield, respectively. The same trend was observed in plants treated with H2O2 + K which recorded the highest values in total carbohydrates and dry matter of potato compared to the control. The increase rate in ascorbate peroxidase, and catalase were 97.3 and 98.2 % compared to the control when potato treated with H2O2 and (Se + K), respectively. Whereas, the decrease rate in the electrolyte leakage were 43.7 and 34.1% in both seasons, respectively when potato plants treated with H2O2 + K. Surprisingly, foliar applied H2O2 treatments were found to be the best anti-stressor against studied disease (Alternalia. solani), which recorded the lowest severity values (6.2, 8.1, and 10.6 %), for (H2O2 and K), H2O2 and (H2O2 and B), respectively in the first season. Among all treatments, foliar applied H2O2 + K was achieved the highest values of total net return (3,356 and 3,118 $/ha), and economic efficiency (1.90 and 1.82) in both seasons, respectively. This study confirmed that the combined foliar application of selected nutrients with H2O2 is better than their sole application against studied stresses. This work also opens more windows to investigate more nutrients in different combinations against abiotic and/or biotic stresses.
