Growth of lettuce cultivars in beds covered with differing materials
Favarato, Luiz Fernando; Guarçoni, Rogério Carvalho; Eutrópio, Frederico Jacob; Mendes, Lidiane; Piassi, MírianIn commercial lettuce growing, the intensive cultivation of the soil results in an increase in weed populations, making it difficult to fully exploit the area and increasing production costs. Under such circumstances, the use of soil covers can minimize this problem. Consequently, the objective of this study was to evaluate the effects of different materials as soil covers on the agronomic performance of three ...
ADAPTATION OF PROGENIES/CULTIVARS OF ARABICA COFFEE (Coffea arabica L.) IN MOUN...
Krohling, Cesar Abel; Matiello, José Braz; de Almeida, Saulo Roque; Eutrópio, Frederico Jacob; Carvalho, Carlos Henrique de SiqueiraBrazil is known for production and worldwide export of coffees. Study of adaptation of new progenies/cultivars of Arabica coffee (C. arabica L.) with resistance to rust in mountainous edaphoclimatic conditions is important for crop renewal and also for new plantations. This study was performed in the mountainous region of the Espírito Santo state, Brazil, with 30 progenies/cultivars of Arabica coffee planted at...
First record of Amphipoda Talitroides topitotum (Burt, 1934) (Gammaridea, Talit...
Eutrópio, Frederico Jacob; Krohling, WertherTalitroides topitotum (Amphipoda) was introduced in Brazil by silviculture activities. Currently the species is distributed in the states of Paraná, Rio de Janeiro and São Paulo. This paper describes the species’ occurrence in the state of Espírito Santo. The objective of this study was to determine the interference of the edge effect on community structure of macroinvertebrates associated with leaf litter, whe...
Population parameters of the shrimp Xiphopenaeus kroyeri (Heller, 1862) (Crusta...
Eutrópio, Frederico Jacob; Mariante, Fátima Lieberenz Falleiros; Ferreira Junior, Paulo Dias; Krohling, WertherThe fishery on Penaeidae shrimp is done all over the Brazilian coast, especially the seabob shrimp (Xiphopenaeus kroyeri). It is captured in large quantities in the Southeast and Southern Brazil. In order to study the population structure of X. kroyeri from Anchieta Municipality, Espírito Santo State, during the period from January to December 2008, monthly samplings with one-hour-long were conducted to verify ...
