“…Chitosan, and all other chitin derivatives, have a high nitrogen content of 6% to 9% (Yen and Mau, 2007), comparable with other organic fertilizers such as dried blood and bone meal (White, 2006). Plants can access the nitrogen in chitin via microbial breakdown and the release of inorganic nitrogen, or by directly taking up monomers as organic nitrogen (Roberts and Jones, 2012;Spiegel et al, 1988). Chitosan can be used to add organic matter to soils without raising the carbon:nitrogen ratio.…”

“…Although chitosan contains nitrogen and calcium, its positive effects on crop growth and yield were not only due to its nutrients, since in some studies the nutrients in chitosan were equalized in the control plots treated with inorganic fertilizers. Ohta et al (2004) and Spiegel et al (1988) demonstrated that chitosan significantly prompted growth of seedlings of several ornamental plants and chinese cabbage (Brassica rapa ssp. pekinensis), compared with standard mineral fertilizer.…”

Chitosan has become of interest as a crop biostimulant suitable for use in sustainable agriculture since it is biocompatible, biodegradable, environmentally friendly, and readily available in large quantity. Short-term (35 d after transplanting) effects of chitosan, applied as a soil amendment at 0%, 0.05%, 0.10%, 0.15%, 0.20%, or 0.30% (w/w), on lettuce (Lactuca sativa) growth, chlorophyll fluorescence, and gas exchange were evaluated in a growth chamber study. Chitosan at 0.05%, 0.10%, and 0.15% increased leaf area from 674 to 856, 847, and 856 cm2, and leaf fresh weight from 28.6 to 39.4, 39.1, and 39.8 g, respectively. Only chitosan at 0.05% and 0.10% increased leaf dry weight from 3.42 to 4.37 and 4.35 g, respectively, while chitosan at 0.30% decreased leaf number, area, fresh and dry weight. Chitosan at 0.10%, 0.15%, 0.20%, and 0.30% increased leaf chlorophyll index from 29.8 to 34.4, 35.4, 37.5, and 41.4, respectively. Chitosan at 0.20% and 0.30% increased leaf maximum photochemical efficiency and photochemical yield, and chitosan at 0.10%, 0.15% 0.20%, and 0.30% increased leaf electron transport rate. Leaf photosynthesis rate and stomatal conductance (gS) increased from 9.3 to 12.7, 14.0, and 16.6 μmol·m−2·s−1 carbon dioxide, and from 0.134 to 0.183, 0.196, and 0.231 mol·m−2·s−1, under chitosan at 0.15%, 0.20%, and 0.30%, respectively. The results indicated that chitosan, at appropriate application rates, enhanced lettuce growth, and might have potential to be used for sustainable production of lettuce.

“…Similarly, 1% chitosan mixed with fertilizer improved the nitrogen and phosphorous content in the roots and shoots of Eustoma grandiflorum (Raf) compared with non-chitosan mixed soil grown plants [ 177 ]. In Chinese cabbage, plants treated with a chitin-based product showed faster growth than plants treated with a standard mineral fertilizer [ 178 ]. In another study, chitosan in combination with N, P, K fertilizer proved to be significant in altering the effect of Botrytis cinerea -caused grey mold disease in Begonia × hiemalis Fotsch, and also increased the antioxidant activities and other commercial traits [ 179 ].…”

The Multifunctional Role of Chitosan in Horticultural Crops; A Review

Chitosan is a naturally occurring compound and is commercially produced from seafood shells. It has been utilized in the induction of the defense system in both pre and post-harvest fruits and vegetables against fungi, bacteria, viruses, and other abiotic stresses. In addition to that, chitosan effectively improves the physiological properties of plants and also enhances the shelf life of post-harvest produces. Moreover, chitosan treatment regulates several genes in plants, particularly the activation of plant defense signaling pathways. That includes the elicitation of phytoalexins and pathogenesis-related (PR) protein. Besides that, chitosan has been employed in soil as a plant nutrient and has shown great efficacy in combination with other industrial fertilizers without affecting the soil’s beneficial microbes. Furthermore, it is helpful in reducing the fertilizer losses due to its coating ability, which is important in keeping the environmental pollution under check. Based on exhibiting such excellent properties, there is a striking interest in using chitosan biopolymers in agriculture systems. Therefore, our current review has been centered upon the multiple roles of chitosan in horticultural crops that could be useful in future crop improvement programs.

“…While chitin has a high thermal and chemical stability [181], making it possible to store dry product for a good length of time, it can quickly be utilized as both a nitrogen source and energy source by plants and microbes when added to crops. Plants can access the nitrogen in chitin via microbial breakdown and the release of inorganic nitrogen, or directly taking up monomers as organic nitrogen [183,184]. Spiegel et al [183] demonstrated that Chinese cabbages treated with chitin-based products grew faster than plants treated with a standard mineral fertilizer.…”

A Review of the Applications of Chitin and Its Derivatives in Agriculture to Modify Plant-Microbial Interactions and Improve Crop Yields

Abstract:In recent decades, a greater knowledge of chitin chemistry, and the increased availability of chitin-containing waste materials from the seafood industry, have led to the testing and development of chitin-containing products for a wide variety of applications in the agriculture industry. A number of modes of action have been proposed for how chitin and its derivatives can improve crop yield. In addition to direct effects on plant nutrition and plant growth stimulation, chitin-derived products have also been shown to be toxic to plant pests and pathogens, induce plant defenses and stimulate the growth and activity of beneficial microbes. A repeating theme of the published studies is that chitin-based treatments augment and amplify the action of beneficial chitinolytic microbes. This article reviews the evidence for claims that chitin-based products can improve crop yields and the current understanding of the modes of action with a focus on plant-microbe interactions.
