| Bio- and nano-fertilizers offer significant economic and environmental benefits for sustainable agriculture. This study investigated the synergistic effects of planting dates, nano-fertilizers, and biofertilizers on canola growth, yield, and oil production at Arish University's Faculty of Agricultural and Environmental Sciences during the 2022–2023 and 2023–2024 seasons. The research employed a randomized complete block design with three replicates and eight treatments across two planting dates (20 October and 20 November). Treatments included a baseline control (T1) receiving 50% recommended soil NPK plus conventional NPK foliar spray (19:19:19 at 3 g/L applied at 30 and 45 DAS); an EM1-supplemented control (T5) consisting of T1 protocol with EM1 biofertilizer (5 mL/m²); and experimental treatments combining EM1 (5 mL/m²) with 50% soil NPK plus foliar nano-NPK (19:19:19) at 1, 3, or 5 mL/L. Results established that the combination of early sowing (20 October), EM1 application (5 mL/m²), and nano-NPK at 5 mL/L significantly enhanced vegetative traits (plant height, leaf number, branch number, leaf and branch weights, root length and weight, and leaf area) and yield components (seed yield, 1000-seed weight, seed weight per plant, pod length, pod weight and number, oil percentage, and oil yield). These findings emphasize the potential of integrating bio- and nano-fertilizers as an effective tool for optimizing canola production under changing climatic conditions. | ||||
