Agronomic performances and nutritional composition of three morphotypes of spider plant (Cleome gynandra L.) under different doses of compost
Spider plant is an important dietary supplement for the local population of Burkina Faso. The present study aims to evaluate the agronomic and biochemical response of three morphotypes to the variation of compost dose. The split-plot design with three repetitions was used for experiment. Three morphotypes, i.e slightly-violet, green and violet, were evaluated using four doses of compost. The results revealed that the agromorphological traits and biochemical composition vary considerably according to the compost dose. About 6t/ha was identified as the best for biomass production and nutritional profile of spider plant. In general, the agronomic response of morphotypes to the variation of compost dose is not significantly different, except biomass. However, under low fertility conditions, the green morphotype records the best performances whereas in high fertility conditions, the slightly-violet records the best performances. For the biochemical composition, the content of nutrients depends more of compost dose than morphotype.
