“…Similar results were observed by several authors who studied changes in Benin's climate (ATIDEGLA et al, 2017;BOKO et al, 2012;DJOHY et al, 2015) and found that Benin had a longer period of water deficit than periods of water surplus in the different seasons.…”

The climate is described by the predominant atmospheric conditions in a particular region and influences several human activities. In agriculture, water availability defines the growth and yield of crops and can be obtained by the water balance. The climate classification also aids to identify suitable areas for agricultural crops. Thus, the aim of this work was to elaborate the water balance and perform the climate classification through the method of Thornthwaite and Mather (1955) for six weather stations (Bohicon, Cotonou-Airport, Kandi-Airport, Natitingou, Parakou-Airport and Savè) located in Benin, Western Africa. For the execution of this work, monthly series of precipitation and potential evapotranspiration from 1970 to 2015 were used. Once the monthly water balance of the six seasons was elaborated, it was observed that the rainy (dry) period decreases (increases) from the coast (Cotonou-Airport) to the north of Benin (Kandi-Airport) and, coincides with Boreal summer and part of autumn (Boreal winter and part of spring). Regarding the climate classification, the Cotonou-Airport station was characterized as Subhumid Megathermal climate with moderate winter deficit (C2wA’a’); the stations of Bohicon and Savè presented similar climate classification with Subhumid Dry Megathermal climate with low or without water surplus (C1dA’a’); Natitingou with Subhumid Dry climate Megathermal with large summer surplus (C1s2A’a’); Parakou-Airport with Subhumid climate Dry Megathermic with moderate summer surplus (C1sA’a’) and, Kandi-Airport presented Semi-arid Megathermal climate with moderate summer surplus (DsA’a’). In Benin, subsistence and rainfed farming showed greater risk in the north of the country due to the decrease in the rainy season and the water surplus from the coast (south) to the north of the country, with the increase in aridity.

RESUMELe maraîchage revêt une importante source alimentaire et constitue l'une des activités les plus génératrices de revenus au Bénin. La présente étude a pour objectif de contribuer à la sécurité alimentaire à travers une meilleure connaissance des cultures maraîchères de même que les difficultés liées à leur production. Les données ont été collectées à travers des enquêtes individuelles auprès de trente-deux (32) maraîchers installés sur le site maraîcher de Grand-Popo. Au total, neuf (9) espèces maraîchères ont été recensées auprès des maraichers provenant de diverses origines. Parmi ces différentes espèces l'oignon constitue la principale culture, ensuite viennent la tomate, la grande morelle, la carotte, la laitue, la betterave, le concombre, l'aubergine et le piment. Les espèces recensées se répartissent en quatre espèces de légumes-fruits (44,45% des espèces), en deux espèces de légumes-feuilles (22,22%) et légumes-racines (22,22%) et en une espèce de légume-bulbe (11,11%). La plupart des exploitations sont confrontées à dix contraintes parmi lesquelles les plus importantes sont les attaques des insectes (46,08% de réponses), les maladies fongiques (25,35% de réponses) et les nématodes (13,08% de réponses). Quatorze (14) pesticides chimiques dont les insecticides (56,25% de réponses), des fongicides (21% de réponses), des nématicides (17,50% de réponses) et des acaricides (5,25% de réponses) ont été répertoriés. Pour une meilleure connaissance des activités de maraîchages au Bénin, il est nécessaire d'étendre l'étude sur tous les sites maraîchers en vue de disposer d'une base complète de données sur les espèces cultivées en maraîchage ABSTRACT Market gardening is an important food source and one of the most income-generating activities in Benin. The present study aims to contribute to food security through a better knowledge of market gardening as A. ADJATIN et al. / Int. J. Biol. Chem. Sci. 13(6): 2750-2764, 2019 2751 well as the difficulties related to their production. The data were collected through individual surveys of thirtytwo (32) market gardeners installed on the Grand-Popo market garden site. A total of nine (9) vegetable species have been identified with market gardeners from various origins. Among these different species, onion is the main crop, followed by tomato, nightshade, carrot, lettuce, beet, cucumber, eggplant and pepper. The species listed fall into four species of fruiting vegetables (44.45% of the species), two species of leafy vegetables (22.22%), root vegetables (22.22%) and one species of bulb vegetable (11.11%). Most farms face ten constraints among which the most important are insect attacks (46.08% of responses), fungal diseases (25.35% of responses) and nematodes (13.08% of responses). Fourteen (14) chemical pesticides including insecticides (56.25% response), fungicides (21% response), nematicides (17.50% response) and acaricides (5.25% response) have been listed. For a better knowledge of market gardening activities in Benin, it will be necessary to extend the study to all...

“…Tomato (Solanum lycopersicum L.) is a herbaceous, perennial, annual, branching-stem plant cultivated worldwide for its fruits which are eaten fresh or processed. In the new climatic context with its corollary of reduced rainfall [1], abiotic diseases are becoming more and more restrictive. Among these diseases, the blossom end rot causes extensive damage, contributing to over 50 % of production loss [2].…”

The blossom end rot of fruit caused by calcium deficiency causes extensive damage going up to more than 50% of yield loss in tomatoes (Solanum lycopersicum L.). The present study was carried out in a greenhouse in a semi-controlled environment to evaluate the effect of aqueous and alcoholic extracts and fertilizing with the powder of the leaves of Jatropha curcas on the growth parameters, the vigor of the plants, the size of the fruit, the rate of blossom end rot fruit, the yield and the accumulation of biomass Cobra 26 and Lindo varieties of tomato. The experimental system was a complete randomized block with 14 treatments repeated 3 times. Control plants were treated with tap water. Estimates of height, annulus diameter, fruit load, fruit size, blossom end rot fruit rate, yield as well as fresh and dry biomass were made. The aqueous extract at a concentration of 2 L/ha had the best vegetative development compared to all the treatments. As for the 3% alcoholic extract, it was the best in reducing the rate of blossom end rot fruits without any loss of yield and in accumulating fresh and dry aerial and root biomass. These results showed that the use of aqueous extracts, alcoholic extracts and the fertilizing with the powder of leaves of Jatropha curcas in the control of the blossom end rot of the tomato makes it possible to reduce efficiently the rate of blossom end rot fruits and the losses of yield.
