Title: Compost leachate a viable bio-stimulant for tomato growth and yield (Solanum lycopersicum)
The use inorganic fertilizer has been identify as a global challenge. The use of acceptable inorganic and different concentrations of vermicompost has been used in an attempt to enhance crop yield and development with the aim of increasing food production. The aim of the study was to investigate the impact of vermicompost tea concentrate extracted from cow manure and grass cutting on physiological responses of tomato (Solanum lycopersicum). A trial investigated the effect of vermicompost leachate on tomato yield. Tomato seedlings were exposed to different vermicompost concentration with 40 ml of NPK fertilizer to enhance seedlings performance at early stage of growth. The various treatments used in the trial were 5% VCL + NPK, 10% VCL + NPK, 20% VCL + NPK, NPK treated and the untreated control. Tomato flower inflorescence was significant at (P<0.01). Tomato fruit, different components at harvest which were, weight wet and dry weight were higher with NPK treated at (P<0.01) than the 5% VCL + NPK, 10% VCL + NPK. Root length in 20% concentration was considerably higher than the other treatments. The results showed that minimum supplementation with inorganic fertiliser may be necessary with vermicompost leachate in order to successfully grow crops in nutrient deficient soil. It was discovered that higher vermicompost concentrations may be required to make up for soil deficiency.
