Soil attributes in agricultural uses and in the Semiarid RN-Brazil in eutrophic Cambisol
Soil attributes are an important tool to identify appropriate practices for crop management. This study aimed at evaluating physical, chemical and mineralogical properties of soil in agricultural uses, regarding its potential and/or restrictions in the municipality de Governador Dix-Sept Rosado (RN). Soil samples with deformed structure were collected with the aid of an auger Dutch-type zigzag layers in the 0.00-0.10;...

Performance evaluation of a motorized ginger juice expression machine
Ginger juice obtained from mechanical expression of fresh ginger rhizomes offers a value-added ginger product which increases market opportunity for farmers. In this study, the performance of a developed motorized ginger juice expression machine was evaluated to determine the effects of moisture content of ginger and screw shaft speed on the expression efficiency, juice yield, expression loss and throughput capacity....
Effect of inoculating seeds with Bradyrhizobium japonicum on the agronomic performance of five varieties of soybean (Glycine max) in CÃ´te dâ€™Ivoire
Recent studies in the Nawa region of Côte d’Ivoire have indicated an acute malnutrition rate of 11.3% among cocoa producers. One of recommended actions from the studies was to diversify agriculture with nutrients rich crops. Introduction of soybean (Glycine max) cropping system could go a long way to ensure food and nutritional security in the region. The current study was conducted in two sites (Logboayo...
