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;...

Effect of inoculating seeds with Bradyrhizobium japonicum on the agronomic performance of five varieties of soybean (Glycine max) in Côte d’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...
