Stability of annual biomass energy production of elephant grass (Pennisetum purpureum Schum.) genotypes in the Northern region of the Rio de Janeiro State, Brazil
The objectives of this study were to estimate the stability of dry biomass production of elephant grass genotypes under an annual harvest regime, in soil-climatic conditions of the Northern region of the Rio de Janeiro State, Brazil, and to compare methodologies for stability analyses of Yates and Cochran (YC), Plaisted and Peterson (PP), Annicchiarico (ANN), Lin an..

Biometric analysis of arabica coffee grown in low potassium nutrient solution under greenhouse conditions
Genetic parameters and associations between morpho-agronomic traits and nutritional efficiencies of arabica coffee cultivars were estimated to identify promising traits to assist in the selection of coffee genotypes efficient in potassium use, under limiting conditions of this nutrient. The experiment was conducted in a greenhouse with 20 arabica coffee cultivars grown in nutrient solution with.. Read More»

Use of elephant grass for energy production in Campos dos Goytacazes-RJ, Brazil
Elephant grass is a tropical forage plant widely distributed throughout Brazil. It was first exclusively used in the livestock sector as cattle feed. The grass is characterized by its high productivity and photosynthetic capacity and is considered as an alternative source of renewable energy. Here, we estimated the general combining ability of the parents and specific combining ability of the h.. Read More»

Snap bean recommendation based on different methods of phenotypic stability
In order to recommend the best strains of snap beans from the Universidade Estadual do Norte Fluminense (UENF) breeding program, different methods of analysis of phenotypic stability were adopted to evaluate the performance of 14 lines (F9 and F10) of indeterminate growth habit, which were compared with 3 controls, namely, 2 commercial varieties (Feltrin and Top Seed Blue Line) and 1 parent (UE..
