Abstract
Objective: A trial of the ten accessions for J curcas was carried out at regional Agricultural Research Center of Maradi in Niger, with aim to evaluate the performance of Jatropha curcas accessions.
Methodology and results: Each accession was represented by two rows and each row has 15 plant trees of J. curcas. Data on the rate of survival and growth parameters of each tree were collected. Results revealed that there is no significant difference between accessions tested for height and diameter. Accessions Katil 13 and GB 14 respectively originated from Mali and Bisseau Guinea were best adapted for the Niger conditions. The yield value of 511 and 445 kg per hectare respectively obtained from Katil 13 and GB 14 in 2012.
