“…The case study can be described as follows: two biofuel production units, one processing jatropha seeds and the other jatropha seed (each with a demand for dry seeds of 300t/year) are considered. The jatropha biofuel production unit is located in the southern Sudanian zone of Burkina Faso, a region where the soil and climatic conditions suit jatropha tree growth, for details of these characteristics see (Bazongo et al, 2016). The B. aegyptiaca biofuel production unit is in the Sahelian region of Burkina Faso.…”

Jatropha curcas is a tree species introduced in Niger as a trial experiment to offset land degradation and for biofuel production. The objective of this study is to contribute to the understanding of this species' potential for adaptation under the edaphic and climatic conditions of Niger through analysis and modeling of the leaf area dynamics. The nondestructive method is used to evaluate the leaf area growth using four provenances and 120 samples of leaves of J. curcas plants. The results show that leaf area is optimal during the wet season of the year with non-significant difference (P > 0.05), while during other periods it is significant (P < 0.05) between provenances. The logarithmic model is the most accurate, and the models developed have a correlation coefficient between 0.95 and 0.99. The error analysis shows a mean absolute percentage of error between 5.92 and 27.43%, depending on the provenances. The accuracies of the developed models were appreciated, with root mean square of error varying from 0.72 to 2.06 cm 2 . Contrary to the expectation, for production of J. curcas in Niger's Sahelian climate and soil, it is necessary to ensure additional irrigation water to the plants, especially during the dry period of the year.

RESUMECette étude a été conduite à la Faculté d'Agronomie de Niamey au Niger. Elle vise, à travers la mesure des paramètres biométriques et pondéral, à sélectionner des semences de Jatropha curcas présentant de bonnes aptitudes à la germination. La longueur, la largeur et le poids moyens des fruits sont respectivement de 2,55 cm ± 10% ; 1,90 cm ± 13,2% et 1,83 g ± 45,36%. Le poids d'un fruit est fortement corrélé à sa longueur et à sa largeur (r =.0,83 et 0,82). La classification des fruits montre que 19,94% sont petits, 62,88% moyens et seulement 17,17% de gros fruits. La largeur, l'épaisseur et la longueur moyennes des graines sont respectivement de 1,10 cm ± 5,5% ; 0,84 cm ± 7,14% et 1,77 cm ± 5,65%. La moyenne du poids d'une graine étant de 0,498 g ± 38,15%. Selon le poids, 20,53% des graines sont petites ; 60% sont moyennes et 19,47% sont grosses. Les caractéristiques de germination au laboratoire et celles de la levée en pépinière sont meilleures pour les grosses graines par rapport aux graines moyennes et petites. Cette étude a permis de distinguer les semences de Jatropha curcas qui offrent les meilleures aptitudes de germination et de levée. Mais, avant toute diffusion, il est nécessaire de poursuivre cette investigation afin d'apprécier la répercussion des différences observées sur tout le cycle de développement de la plante. © 2016 International Formulae Group.

(Euphorbiaceae) in experimental condition in Niger ABSTRACTThis study was conducted at the Faculty of Agriculture, UAM Niamey, Niger. It focuses on measuring the biometric parameters and weight, to select Jatropha curcas seeds with good germination capabilities. Length, wide and weight averages of fruits are respectively 2.55 cm ± 10% ; 1.90 cm ± 13.2% and 1.83 g ± I. CHAIBOU et al. / Int. J. Biol. Chem. Sci. 10(2): 749-759, 2016 750 45.36%. The weight of a fruit is highly correlated to its length and wide (r = 0.83 and 0.82). Classifications shows 19.94% of fruits are small, 62.88% are medium and only 17.17% are thick. Wide, thickness and length averages of seeds were respectively 1.10 cm ± 5.5% ; 0.84 cm ± 7.14% and 1.77 cm ± 5.65%. The weight average of seed was 0.498 g ± 38.15%. Accordingly, the weights (20.53%) of seeds were small, 60% were medium and 19.47% were thick. The laboratory assey on germination characteristics and those of the lifting nursery were best for larger seeds compared to medium and small seeds. Thus, this study helped to distinguish Jatropha curcas seeds with best capabilities of germination and emergence. But before distribution, it is necessary to go on with the investigation in order to assess the impact of differences throughout the plant life cycle.
