Aperçu sur les produits phytosanitaires de la floriculture à dakar-sénégal

Le secteur de la floriculture est en pleine expension au Sénégal et particulièrement à Dakar où il est noté une importante diversité végétale constituée aussi bien d’espèces autochtones que d’espèces introduites. Parmi les contraintes de la production de ces espèces figurent les ennemis des cultures (adventices, maladies et ravageurs. Pour faire face à ces contraintes biotiques, plusieurs produits phytosanitaires sont utilisés dans les exploitations florales.

Comparative study of the nutritional potential of some starchy food (potato, yam, cassava, Sweet potato and taro) in rats

The objective of this study is to compare the chemical composition and nutritional quality of potato, yam, cassava, sweet potato and taro. For this purpose, the rats of wistar strain, weighing on average 67.5±2.94 g, were fed diets based on these starchy foods. 30 growing rats were used for the experiment, with 6 rats per diet containing herring fish as protein source (10 %). Energy value ranges from 137.44±2.40 Kcal/100 g (yam) to 396.15±0.01 Kcal/100 g (cassava). Lipids contents are between 0.08±0.01 % DM (potato) and 1.07±0.01 % DM (cassava).

Problem confronted by the growers in spices cultivation practice in Shibganj Upazila under Bogura District

The main objective directed the present study was to identify the problem confronted by the growers in spices cultivation in Shibganj upazila under Bogura district. Three unions of the upazila were purposively selected based on the vicinity to the Spices Research Center, Bogura. Ninety growers were randomly selected from 270 spices growers in three unions of the upazila. Data were collected from selected growers using pre-tested interview schedule.

Nutritional status of schoolchildren at a municipal school in the interior of piauí

Objective: to analyze the nutritional status and eating habits of schoolchildren from the 2nd to the 5th year at a school in the city of Cristino Castro - PI, with children aged 8 to 19 years. Methodology: This study dealt with a descriptive exploratory field research with a quantitative approach. Results and Discussion: 40 students agreed to participate in the research, 16 male and 24 female.

Phytomass and iron accumulation in green corn fertilized with ferrous sulfate

The low availability of cationic micronutrients such as iron (Fe) in alkaline soils can limit the production of phytomass, the production of ears and the nutritional quality of green corn. The objective was to evaluate the influence of Fe concentration, via leaf, on phytomass, grain production and the Fe accumulations in the leaves and green grains of corn growing in alkaline soil. The experiment was carried out in a randomized block design, with five Fe concentration (0, 1, 2, 3 and 4 g L -1) and four blocks totaling 20 experimental plots.

Polymorphism of microsatellite markers developed from homologous genomic regions of phaseolus vulgaris to meloidogyne ssp. resistance genes identified in soybean

DNA markers can contribute to the genetic control selection of many diseases in plants. Nematodes belonging to genus Meloidogyne gather pathogens that cause damage and yield losses in Phaseolus vulgaris. Although the sources of genetic resistance variations are known in legumes such as soybeans, little is known about this feature in common bean crops. This study aimed to characterize the polymorphism of microsatellite markers developed to extend the resistance genes of P. vulgaris to Meloidogyne spp.

Health promotion in public outreach programs of a Brazilian public university

Health promotion as a field of knowledge combined with public outreachprograms is a differential in training health professionals, strategic for social action and humanized care. This study aimed to identify the outreach programs carried out at a public university in Central-West Brazil andverify their useof health promotion concepts. This documentary researchcollected datainthe electronic platformaccessing the university’s portal, surveying allprojects registered in 2017. Unfinished actions were excluded.

Evaluation of different population arrangments to be used in soybean culture in order to improve your productive system

Given the relevance of soybean culture in Brazilian agriculture, new sowing systems have been researched in order to improve its production system. Among these, the double row sowing technique is standing out as an alternative in which the spatial arrangement of plants can be reflected in significant increases in grain productivity. However, in relation to the effect of row spacing, there are conflicting results in the literature.

Contribution to the study of nutritional value of termitomyces letestui, termitomycessingidensis and termitomyces striatus, three comestible mushrooms in the Republic of Congo

Termitomyces letestui, Termitomyces singidensis and Termitomyces striatus, fungi that grow in the savannahs and forests of the Republic of Congo in the wild. These fungi are rich in protein (values ranging from 28 to 36.5%), lipids (1.47 to 4.43%) carbohydrates (31.56 to 45.34%). Ash content ranges from 13.73 to 38.97%. We got among the ions identified: Phosphorus: 119.7 to 222.7 mg/100g; Iron: 10 to 31.8 mg/100g; Calcium: 1.9 to 3.9 mg/100g; Sodium: 0.8 to 1.2 mg/100g; Potassium 302 to 333.8 mg/100g and Magnesium: 12.9 to 15.2 mg/100g. The value ranges from 247.09 to 267.23Kcal/100g.

Increasing rates of phosphate fertilizer with and without controlled release on corn and soybean in the Brazilian cerrado region

The objective of this study was to evaluate the efficiency of controlled release technology as well as testing different rates for P fertilization. This research was carried out in Midwest Brazil in the Cerrado region. The soil is characterized as a Ferralsol. We tested two commercial fertilizers with and without P controlled release technology and application rates of 50, 75, 100 and 125% of the recommended rate for each fertilizer. Our results demonstrated that phosphate fertilization significantly increased corn yield components from the second season after the operation.
