Seaweed extracts contain a number of plant growth promoting compounds. The extract of Kappaphycus alvarezii, a red seaweed cultivated in the southeast coast of India is commercially exploited for enhancing plant growth and yields. The commercial product, â€œAquasapâ€, has been found to increase crop yields of a number of rainfed crops in India. ICRISAT evaluated â€œAquasapâ€ in a number of rainfed crops in the watersheds and observed the beneficial effects of spraying the solution in soybean, maize, groundnut, sunflower, etc. Crop yields increased by 11 to 36% over the control (spread with water), underlining its potential use under water stressed situations. It is now proposed to evaluate the response of â€œAquasapâ€ formulations (powder and concentrated forms) on different crops (cereals, legumes, and vegetables) grown in select countries in Eastern and Southern Africa.
