Influence of organic substrates on growth and nutrient contents of jatobá (Hymenaea stigonocarpa)

The use of native forests for the purpose of agricultural and livestock occupation have caused the degradation of native ecosystems of caatinga and cerrado. The negative impact of these activities can be minimized with the revegetation of degraded areas. With that comes the need to produce seedlings of native forest species of quality. The objective of this study was to evaluate how the addition of bagana of...

Effects of pre-sowing treatments on Jatropha curcas seed germination and seedling growth

This study aimed to investigate the effects of different pre-sowing treatments on Jatropha curcas seed germination rate and seedling early growth. Growth and vigour of the seedlings was assessed through the measurements of growth parameters, in order to identify the best pre-sowing treatment, which guarantees both the highest seed germination rate and the best development and growth of the seedlings. J. curcas seeds of...

Competitiveness of smallholder legume production in South Kivu region, Democratic Republic of Congo

This study investigated the returns to legumes (common bean and soybean) and other principal crops (cassava, sweet potato and maize) in South Kivu, Eastern Democratic Republic of Congo. Data were collected using a structured questionnaire from a randomly selected sample of 291 farmers who had participated in N2Africa project in the four Eastern D. R. Congo territories: Kabare (103), Kalehe (52), Mwenga (24) and Walungu...

Corn agronomic evaluation under different doses of nitrogen and seed inoculation in savanna

The agronomic potential of corn is below the genetic potential of high technology hybrid available in Brazil due to the inadequate management of soil fertility, especially of nitrogen fertilizer, essential photosynthetic activity and determining the crop yield. This study evaluated the agronomic performance and yield of maize culture grown with increasing doses of nitrogen (N), in the absence and presence of...

Fungal population, including Ochratoxin A producing Aspergillus section Nigri strains from Ivory Coast coffee bean

The mycotoxin contamination in foods has become a growing threat and aroused many researches in science area. According to the food control authorities, Ochratoxin A (OTA) is among mycotoxins priority of food contaminants. The current work focuses on coffee cherries quality environment in Ivory Coast. The neglecting of good agricultural practices would lead to recurrent contamination of ivorian coffee in mycotoxinogen...

Exports and market power of the soybean processing industry in Brazil between 1980 and 2010

The objective of this research was to identify whether the majors of the soybean production chain in Brazil have conditions to design their market power and capture part of the economic surplus farmers? In this context, based on the analysis of price elasticity, drawn from the postulates of neoclassical microeconomic theory, it was found that exports of soybeans and soybean meal are inelastic to price. Therefore,...

Effects of hydrogel and nitrogen fertilization on the production of arugula in successive crops

Appropriate management techniques, such as fertilization programs and the use of technology in the production process, have been employed to meet the demand for vegetables year-round. Because vegetables require a considerable amount of water for their development, hydrogels can guarantee the supply of water in regions with water deficits. The aim of this study was to evaluate the use of hydrogel and nitrogen fertilizer...
