Boosting Intercropping Yields with Seaweed Biostimulants and Cyanobacteria

Overview

This research initiative explores a sustainable intercropping strategy that combines rice-wheat cultivation with nitrogen-fixing cyanobacteria inoculation and seaweed biostimulant application. The goal is to demonstrate that these natural inputs can cost-effectively increase crop productivity, improve soil health, and enhance nutrition while reducing reliance on synthetic fertilizers. By integrating cyanobacteria and seaweed extracts into an intercropped field setting, the research seeks to validate a practical approach for improving agricultural sustainability, resource efficiency, and profitability.

Technical specifications

Key research components:

• Seaweed biostimulants: Application of commercial seaweed extracts as foliar sprays to enhance crop growth, antioxidant activity, and nutrient content
• Cyanobacteria inoculation: Introduction of nitrogen-fixing cyanobacteria cultures into surface soil to improve nitrogen availability and soil microbiome health
• Intercropping system: Rice-wheat rotation with combined treatments including seaweed extracts alone, cyanobacteria alone, and their combination
• Experimental design: Randomized complete block experiment with controlled foliar spray application for consistency
• Measured outcomes: Plant growth metrics, nutrient uptake, stress resistance, soil health indicators, cyanobacteria population dynamics, crop productivity, and nutritional value

Technology readiness level

This research is at the early-to-mid stage of validation. Prior studies have established the individual benefits of seaweed extracts and beneficial microbes on crop growth and soil health in controlled settings. The proposed work extends these findings into a field-scale rice-wheat intercropping system, with planned demonstration trials to track productivity, soil health, nutrition, and economic value. Future validation includes sample collection and preparation, cyanobacteria culturing and soil colonization studies, randomized field experiments, and statistical analysis of treatment effects on crop productivity and sustainability.
