Ítem Restringido Production, testing and marketing of seaweed and humified organic matter biostimulant in Ghana and Zambia.(Universidad EARTH, 2019-12) Aduteye, Erasmus Kabu; Chitubila, Salome; Singh, B. K.The use of plant biostimulants is a common practice in agriculture that improves crop yields by stimulating growth and providing protection against stress. Biostimulants are employed to reduce the use of chemical fertilizers and thus help mitigate the negative environmental effects caused by the overuse of synthetic fertilizers. A study was conducted at EARTH University, Costa Rica, to formulate and test the effectiveness of seaweed and humified organic matter-based biostimulants and their ability to increase the yield of lettuce and onions. Four treatments were tested, each in three dilutions: a seaweed biostimulant (T1), humified organic matter biostimulant (T2), mixture of seaweed and humified organic matter biostimulant (T3) and EcoHum biostimulant (T4). The biostimulants were applied to the lettuce (Lactuca sativa) and onion (Allium wakegi) leaves. Data collection was done at 35 days after transplanting (DAT) for the lettuce and 63 DAT for the onions. The highest average fresh weight of 60.94 g was recorded from the lettuce crop that grew under the T2 treatment (humified organic matter biostimulant) with a dilution of 5 mL:1500 mL, and the highest average fresh weight of 25.76 g was recorded from the onion crop that grew under the T1 treatment (seaweed biostimulant) with a dilution of 5 mL:1000 mL. The application of a mixture of seaweed biostimulant and humified organic matter biostimulant with dilutions of 5 mL:1500 mL for lettuce and seaweed biostimulant 5 mL:1000 mL for onions is recommended for better weight and crop yield. To introduce biostimulants in Ghana and Zambia, market surveys were conducted in both countries, and the results showed that it is possible to establish a biostimulant industry for commercial production since raw materials are easily accessible in the southern part of Ghana and the Kafue Tropical Flats in Zambia.
