Also, it could be attributed to increasing the uptake of nitrogen and its associated role in chlorophyll synthesis, which in role hence the process of photosynthesis and carbon dioxide assimilation (Jasso-Chaverria et al., 2005). [1] El Hadrami, Abdelbasset, et al. N, particularly for 0.010 % treated plants, both in maize and soybean. Nowadays, applying bio-organic fertilizer (e.g., chitosan, Ch) or integrating beneficial microorganisms (e.g., arbuscular mycorrhizal fungi, AMF) are among the successful strategies to promote plant growth. All the treatments significantly increased the fruit yield, number of fruits, average fruit, p>The yield of maize is highly sensitive to nitrogen fertilizer rates and plant spacing. Key Message: Chitosan foliar application enhances yield with booting thermos-tolerance ability by improving enzymatic and non-enzymatic antioxidant systems in cucumber genotypes under high temperature. Chitosan foliar treatment at the rate of 250 ppm dissolved in acetic acid (0.5 %) according to (Bautista-Baños et al., 2006). RGR were determined following the methods of Hunt (1978). Chitosan is known to have eliciting activities leading to a variety of defense mechanisms in host plants in response to abiotic stress, microbial infection and parasitic nematodes, including the accumulation of phytoalexins, Pathogen-Related (PR) proteins and proteinase inhibitors, lignin synthesis and callose formation. Results showed that the water deficit stress reduced the plant dry weight, while increased total phenol and essential oil contents. The application of water deficit stress and foliar treatment with chitosan (three steps) was performed three weeks before flowering. 2. However, foliar application of chitosan at 500 mg/L under water deficit stress conditions increased dry weight of shoots, and phenol content.
