Benefits of Chitosan in Agriculture

Chitosan boosts nutrient absorption and root growth for better yields. It also strengthens plants against stress and reduces chemical pesticides, making farming more sustainable and crops healthier.

1) Improve Crop Yields

Chitosan optimizes nutrient absorption by improving root growth and making nutrient uptake more efficient. Studies prove that chitosan can significantly increase crop yields:

  • Tomatoes: Chitosan treatment on tomato plants led to a remarkable 58.5% increase in fruit yield (Parvin et al., 2019).
  • Soybeans: Applying chitosan to soybean crops resulted in a 38% increase in yield (Darwis et al., 2014).
  • Wheat: Chitosan application under salinity stress increased shoot biomass by up to 44% and root biomass by up to 87%, significantly boosting overall crop productivity. (Quitadamo et al., 2021).
  • Rice: Chitosan can boost rice yield by up to 17%, primarily through seed soaking and soil application, enhancing grain weight and overall productivity (Boonlertnirun et al., 2007).

By enhancing crop yields, chitosan helps farmers achieve better productivity and higher returns, making agriculture more efficient and profitable.

2) Boost Chlorophyll Levels to Promote Photosynthesis

Chlorophyll plays a crucial role in photosynthesis by absorbing light and storing it as an energy source. The energy is then used in the photosynthesis process to feed the plant.

By boosting photosynthesis, chitosan ramps up the production of glucose and other essential carbohydrates, resulting in more significant plant growth and increased biomass.

Research shows chitosan enhances chlorophyll levels:

  • Fenugreek: Chitosan-treated plants under saline stress showed significant increases in chlorophyll levels. Chlorophyll a increased by 43.7%, chlorophyll b by 65.4%, and carotenoids by 28% at 250 mM salinity. (Yahyaabadi et al., 2016).
  • Verbena: Foliar application of chitosan enhanced chlorophyll by 13.4% (Salachna et al., 2017).
  • Rice: Chitosan increased chlorophyll a by 38% and chlorophyll b by 29% under salt stress, improving photosynthesis. It boosted shoot length and dry weight by 20-25%, leading to a higher yield. (Khaleduzzaman et al., 2021).

Chitosan makes plants grow and thrive with its natural properties. With improved photosynthetic capacity, plants can fix more carbon and synthesize growth-promoting carbohydrates, making them stronger and more resilient.

3) Film-Forming Ability

Chitosan forms protective films that can be used to coat seeds and leaves. It creates a barrier to:

  • Prevent pathogen invasion.
  • Maintain moisture around the seed, promoting better germination rates.

Pathogen invasions that attack plants or reduce growth can be limited by:


Seed Coating

  • Pathogen Protection: Coating seeds with chitosan provides a protective barrier against soil-borne pathogens, reducing infection rates and improving overall plant health during the critical initial growth stages (Dzung et al., 2011).
  • Chitosan films can enhance germination and growth: Chitosan-coated seeds exhibit higher germination rates and better resistance to soil-borne pathogens, improving the chance of seedling growth.


Foliar Spray

  • Disease Prevention: As a foliar spray, chitosan forms a protective barrier on leaves that prevents the penetration of pathogens. This barrier helps reduce the incidence of diseases like powdery mildew and leaf blight, increasing yield by almost 20% (Walker et al., 2007).
  • Improved Nutrient Absorption: Chitosan's film-forming ability enhances nutrient absorption by improving the leaf's surface characteristics, allowing for better uptake of water and nutrients. This leads to healthier plants with increased growth rates and 42% higher yields (Rahman et al., 2018).

Chitosan's film-forming properties make it effective and versatile in modern agriculture. By protecting seeds and leaves, chitosan promotes healthier, more resilient plants capable of higher productivity and better disease resistance.

4) Increase Stress Tolerance with Chitosan

Soil worldwide is rapidly depleting due to abiotic stresses exacerbated by climate change. Chitosan enhances plants' resilience to withstand these stresses, ensuring survival and growth under challenging conditions:


Salinity Tolerance

Soil salinity causes osmotic and ionic stress, leading to nutritional imbalances, chemical buildup, limited carbon exchange, and reduced root water uptake – all detrimental to plant growth. Chitosan mitigates these effects by:

  • Alleviates Salt Stress: In saline conditions, applying chitosan alleviates membrane lipid peroxidation in lettuce plants while enhancing crucial stress-survival enzymes like peroxidase and catalase (Zhang et al., 2021).
  • Improves Growth: Under salt stress, chitosan significantly improves plant growth and yield. In common beans, it enhances pigment fractions, carbohydrates, and antioxidants. It reduces hydrogen peroxide, lipid peroxidation, and electrolyte leakage (Alenazi et al., 2024).
  • Modulates Ion Concentration: Chitosan curbs sodium accumulation while boosting potassium levels in NaCl-treated plants, maintaining a healthy K+/Na+ ratio vital for overall plant health (Zhang et al., 2021).


Drought Resistance

Drought severely limits water availability, hindering plant growth and crop yields. Chitosan helps plants cope with drought stress by:

  • Enhancing Antioxidant Enzymes: Chitosan treatment boosts the production of antioxidant enzymes like superoxide dismutase (SOD) and catalase (CAT) that scavenge reactive oxygen species (ROS). These enzymes protect plants from oxidative damage caused by drought (Quitadamo et al., 2021).
  • Improving Water Retention: Chitosan enhances plants' ability to retain water by increasing root growth and improving water uptake efficiency. This helps plants access and utilize water more effectively during drought conditions (Li et al., 2017).
  • Stomatal Closure: Chitosan induces abscisic acid (ABA) synthesis, which triggers stomatal closure. This process reduces water loss through transpiration, helping plants conserve water (Hidangmayum et al., 2019).
  • Boosting Photosynthesis: Even with limited water, chitosan maintains higher photosynthetic activity, allowing plants to continue producing energy for growth (Demehin et al., 2024).
  • Reduced Water Use: Foliar application of chitosan cut water use in pepper plants by 26–43% without affecting biomass production and yield (Bitelli et al., 2017).

These combined effects improve the plant's resilience to drought, enhancing survival rates and productivity under water-limited conditions.


Temperature Tolerance

Extreme temperatures, whether high (heat stress) or low (frost damage),can severely impair plant growth by damaging cellular structures, inhibiting photosynthesis, and disrupting water uptake. Chitosan enhances tolerance to temperature extremes by:

  • Increasing Yield: Foliar spraying of chitosan with zinc and humic acid helps dry bean plants withstand heat stress from late sowing (Ibrahim & Ramadan, 2015).
  • Improving Membrane Stability: Chitosan treatment preserves membrane integrity, reducing damage from heat stress. This helps maintain cellular function despite high temperatures (Yang et al., 2009).
  • Increasing Cold Tolerance: Chitosan helps plants produce more cold-responsive proteins, enhancing their ability to survive low temperatures. This includes maintaining membrane fluidity and preventing ice crystal formation within cells.
  • Boosting Photosynthesis: Under hot and cold stress, chitosan enables plants to maintain higher photosynthetic rates, ensuring continued energy production and growth (Li et al., 2017).

These combined effects improve resilience to temperature extremes, enhancing survival rates and productivity under either high or low temperatures.
