Effect of Burned Multi-Crop Ashes on Faba Bean-Development Parameters

Area of Science:

• Agricultural Science
• Environmental Science
• Agronomy

Background:

• Plant biomass ash is a combustion residue with potential for agricultural use.
• Sustainable fertilization practices are crucial for environmental protection and crop nutrition.

Purpose of the Study:

• To evaluate the effects of multi-crop biomass ash on faba bean growth.
• To determine optimal ash fertilization rates for faba bean cultivation.

Main Methods:

• A pot experiment was conducted using faba bean seedlings.
• Four fertilization rates of biomass ash were tested: 0, 200, 1000, and 2000 kg ha⁻¹.
• Plant height, root length, chlorophyll concentration, and biomass were measured.

Main Results:

• Ash fertilization significantly increased faba bean sprout height (21-38%) and root length (10-20%).
• Chlorophyll concentration in leaves increased by 17%, with green biomass increasing by 56-209% and dried biomass by 160-220%.
• Higher ash rates (1000 and 2000 kg ha⁻¹) resulted in the largest plants with the highest productivity potential.

Conclusions:

• Multi-crop biomass ash effectively enhances faba bean growth and biomass production.
• Medium to high ash fertilization rates are recommended for optimal faba bean yield.
• Utilizing biomass ash offers a sustainable method for crop nutrition and waste management.
