Effect of planting density and varying rates of organomineral fertilizer on growth, yield and nutritional quality of tomato (Solanum lycopersicum L.). Annals: Food Science & Technology, 21(2).https://uilspace.unilorin.edu.ng/handle/123456789/14088Tomato, one of the most important vegetables cultivated and consumed worldwide plays a significant role in human nutrition. Low soil fertility and inappropriate planting density are major constraints to its production in the Southern Guinea Savanna ecology of Nigeria. Field trials were conducted during the cropping seasons of 2016 and 2017 at the Faculty of Agriculture Teaching and Research Farm (Vegetable Field), University of Ilorin, Ilorin, Nigeria to evaluate the response of tomato to plant population density and different regimes of organomineral fertilizer (OMF) application. The experiment was a split-plot arrangement laid down in Randomized Complete Block Design. The main plot comprised of three population densities (66,000 plants/ha, 50,000 plants/ha and 40,000 plants/ha) and four rates of organomineral fertilizer (0kgN/ha, 50kgN/ha, 100kgN/ha and 50 kgN/ha) as sub-plot in three replicates. Data collected on plant height, number of leaves and branches, yield and yield components and phytochemical parameters were subjected to Analysis of Variance and significant means were separated using Least Significant Differences (P<0.05). The results from the study showed that there was significant effect (p<0.05) of plant population and rates of organomineral fertilizer(OMF) on plant height, number of leaves/plant, number of branches/plant, number of days to 50% flowering, yield/plant and yield/hectare. Fruit quality parameters such as B-Carotene, vitamins A and C and Total Soluble Solid were also affected significantly by the interaction effect of plant density and OMF application rate. The study concluded that planting density of 50,000 plants/ha and application of OMF at 100 kgN/ha which favoured high fruit yield and nutritive value was most suitable for optimum production of tomato in the study area.enTomatopopulationOrganic fertilizersoil fertilitycarotenoidsArticle
