Comparative effects of mineral fertiliser doses on tomato yields

The Sahel is suffering from the effects of climate change. Market gardening, which is mainly practised by women in the Sahel, is a source of income to supplement household needs. Tomatoes are a short-cycle crop with high yields and a high commercial and vitamin value, but they are nutrient-demanding and therefore require adequate fertilisation, which is unfortunately not well controlled. The study was conducted to assess the effect of fertiliser doses from IER/Mali and CDH/Senegal, under irrigation, during the 2014-2015/2015-2016 seasons. R software version 2.14 was used for data analysis. Hypothesis testing for normality and homoscedasticity of variances (Shapiro-Wilk test, Shapiro Francia test and Bartlett test); post hoc analyses (Kuskal-Wallis test and Wilcoxon Mann Whitney pairwise test) and Student's t test on data from the two campaigns, were performed. Improving tomato yields in the Sahel requires the use of chemical fertilisers, hence the need to continue research into identifying efficient doses to promote this crop.
