Summary of Biostimulant Application with a Tropical Plant Extract Enhances Corchorus olitorius Adaptation to Sub-Optimal Nutrient Regimens by Improving Physiological Parameters
How a Tropical Biostimulant Enhances Corchorus Growth Under Low Nutrient Conditions
The application of a tropical biostimulant enhances Corchorus adaptation to sub-optimal nutrient regimens, providing an effective approach to improve crop performance in low-input systems. Greenhouse jute (Corchorus olitorius L.) treated with a commercial vegetal-derived biostimulant from tropical plant extract (PE; Auxym®, Italpollina, Italy) demonstrated significant improvements in morphological, physiological, and biochemical parameters. Weekly foliar applications of 2 mL·L−1 PE supported plants under full-, half-, and quarter-strength nutrient solutions, showing that tropical biostimulants enhance Corchorus productivity even under nutrient-limited conditions.
Morphological Improvements: How Tropical Biostimulants Enhance Corchorus Leaf and Biomass Development
Nutrient limitation often reduces plant height, leaf number, and dry biomass. However, a tropical biostimulant enhances Corchorus by increasing fresh yield by 15.5% at half-strength and 29.5% at quarter-strength nutrient solutions. PE application promoted leaf expansion and overall plant vigor, demonstrating the ability of tropical biostimulants to sustain growth despite sub-optimal nutrients.
Physiological Benefits: Tropical Biostimulants Enhance Corchorus Photosynthesis and Chlorophyll Content
Foliar application of PE improved net CO2 assimilation (ACO2) and SPAD index, reflecting higher photosynthetic efficiency. Chlorophyll b content increased, helping plants adapt to fluctuating light conditions. Under full-strength nutrient solutions, tropical biostimulants enhanced starch accumulation, soluble proteins, and total amino acids, highlighting their regulatory role in key metabolic pathways.
Biochemical and Nutrient Regulation: How Tropical Biostimulants Enhance Corchorus Nitrogen and Mineral Balance
PE reprogrammed nitrogen allocation from glutamate, maintaining efficient photosynthesis under nutrient stress. Essential minerals such as nitrate, potassium, and magnesium increased, while sodium accumulation was reduced. These balanced effects show that tropical biostimulants enhance Corchorus by improving nutrient uptake, transport, and protein synthesis.
Sustainable Crop Productivity Through Tropical Biostimulants
Overall, applying a tropical biostimulant strengthens Corchorus growth, optimizes nutrient use, and increases yield in low-input agricultural systems. By regulating metabolic and physiological processes, tropical biostimulants provide a natural solution for sustainable productivity under challenging environmental and nutrient conditions.
