Organic fertilizer priming enhances eggplant seeds performance

Area of Science:

• Agricultural Science
• Plant Physiology
• Sustainable Agriculture

Background:

• Physiological conditioning of seeds with bioinputs is crucial for enhancing germination and crop yields.
• Organic fertilizers with biostimulant properties offer a sustainable approach to improve seed performance.

Purpose of the Study:

• To evaluate the effectiveness of organic fertilizer priming on eggplant seeds.
• To compare the impact of priming on high-vigor and low-vigor seed lots.

Main Methods:

• A completely randomized design with a factorial arrangement (2 seed lots × 5 biofertilizer doses) was employed.
• Treatments included five doses of organic fertilizer (0 to 0.8 mL L-1) and unprimed controls.
• Seed germination, physiological quality, and seedling vigor were assessed under laboratory and greenhouse conditions.

Main Results:

• Priming low-vigor eggplant seeds with organic fertilizer significantly improved germination and overall performance.
• High-vigor seed lots showed an enhanced seedling emergence rate after priming.
• Seedling length and mass increased with priming, particularly at the 0.8 mL L-1 biofertilizer dose.

Conclusions:

• Organic fertilizer priming is a viable strategy to boost eggplant seed vigor and germination rates.
• This method promotes uniformity and successful seedling establishment, contributing to higher crop yields.
• Biofertilizer application supports sustainable farming practices by improving seed quality naturally.
