Effect of biological fertilizers on the production of tomato (Solanum Lycopersicum L.) in the district of Ngaoundere I (Adamawa, Cameroon)

Abstract

Tomato remains the most profitable vegetable crop in the country and is the most consumed and cultivated in Cameroon. However, the production of crop tomatoes is not enough due to soil degradation. To change this situation, the study of the effect of biological fertilizers on tomato (Solanum Lycopersicum L.) production in the district of Ngaoundere I (Adamawa, Cameroon) was done. The experimental set-up was a complete randomized block with 6 treatments: Chicken Droppings (Cd), mycorrhizae (M), Vivianite Rock Phosphate (VRP), combinations of 2 fertilizers (M + VRP, M + Cd, and VRP + Cd), the positive control (C+) which receive NPK 20-10-10 and the negative control (C-) which receive nothing repeated 3 times. These biological fertilizers used in this study improved the yield production of Lycopersicon esculentum by 70%, 60%, and 54% for Cd + M, Cd + VRP, and M + VRP treatments respectively compared to the negative control (C-).
