1 December 2014. Philip Lajudie (CIRAD-IRD) provides a comprehensive overview of his team's research on the development of crotalaria for crop protection purposes.
Crotalaria juncea as green manure and for nematode population control in Mediterranean vegetable production
We will present our results obtained in the framework of the recent European project Legume Futures. We tested the tropical non-crop legume Crotalaria juncea for biological control of phytoparasitic root-knot nematode populations and green manure effect in greenhouse tunnel vegetable production in Mediterranean conditions. Results show that C. juncea (1) grows rapidly in Mediterranean conditions producing a significant biomass with a very positive green manure effect on lettuce production in both sites. Within two successive campaigns it significantly reduced on lettuce gall scores. Mycorrhization index and rate of C. juncea are significantly higher than that of ryegrass used as a reference mycorrhizogenous plant. Plants nodulate and about fixed about 50 kg N/ha in just 3 months.
