[email protected]     1 RESUMO   O ajuste de estratégias de adubação aliadas ao manejo racional da irrigação para o uso sustentável da água na produção de tomateiro destinado ao processamento industrial pode contribuir com a cultura do tomate. Avaliou-se a influência da adubação organomineral e de lâminas de reposição deficitária aplicadas via gotejamento sobre o crescimento e a produtividade do tomateiro industrial. Conduziu-se um experimento em campo utilizando a cultivar de tomateiro industrial BRS Sena. Utilizou-se delineamento experimental de blocos completos casualizados, em esquema fatorial (4 x 2), sendo quatro lâminas de irrigação (55, 70, 85 e 100% da ETC) e fertilizantes (organomineral e mineral). A irrigação utilizada foi por gotejamento e realizada diariamente de acordo com a evapotranspiração de referência (ET0). Avaliou-se: altura de plantas, diâmetro do caule, número de ramos laterais, número de frutos por planta, produtividade, produção de frutos planta-1, percentual de frutos defeituosos, massa fresca frutos defeituosos, percentual de podridão mole nos frutos, percentual de lóculos abertos, percentual de escaldadura nos frutos, percentual de broca grande nos frutos, percentual de podridão apical nos frutos, diâmetro longitudinal médio, diâmetro equatorial médio, sólidos solúveis totais, massa fresca de frutos e massa seca de frutos. A aplicação de fertilizante organomineral proporcionou maior produção de frutos por planta e maior diâmetro de frutos. As características biométricas correlacionaram-se entre si. A produção de frutos por planta e a produtividade aumentam linearmente com o incremento da taxa de reposição da evapotranspiração diária do tomateiro.   Palavras-chave: Solanum lycopersicum L., organomineral, reposição de água deficitária, manejo da irrigação ALMEIDA, M.

REPLENISHMENT OF WATER AND FERTILIZATION WITH ORGANO-MINERAL IN THE GROWTH AND PRODUCTION OF INDUSTRIAL TOMATO.     2 ABSTRACT   The adjustment of fertilization management strategies associated with the rational management of irrigation for the sustainable use of water in the production of tomato destined for industrial processing can contribute to tomato crops. The objective of this study was to evaluate the influence of organomineral fertilization and replacement of deficient depths applied by drip irrigation on the growth and yield of industrial tomato. An experiment was conducted in field using BRS Sena industrial tomato cultivar. A randomized complete experimental block design was used in a factorial scheme (4 x 2), with four irrigation depths (55, 70, 85 and 100% ETC) and fertilizers (organomineral and mineral). The irrigation used was by drip system and performed daily according to the reference evapotranspiration (ET0). The following items were assessed: plant height, stem diameter, number of lateral branches, number of fruits per plant, productivity, plant-1 fruit production, percentage of defective fruits, fresh mass defective fruits, percentage of soft rot in fruits, percentage of open lobes, percentage of fruit scald, percentage of large fruit borer, percentage of apical rot in fruits, average longitudinal diameter, average equatorial diameter, total soluble solids, fresh fruit mass and dry fruit mass. The application of organomineral fertilizer resulted in higher production and diameter of fruits per plant. Biometric characteristics correlated with each other. Fruit production per plant and productivity increased linearly with the increase in the replacement rate of daily evapotranspiration of tomato.   Keywords: Solanum lycopersicum L., organo-mineral, deficit water replacement, irrigation management

Herein we present the first lists of anuran species of five islands off the coast of Rio de Janeiro State, Brazil, and updated lists for two other islands (Ilha Grande and Ilha da Marambaia). These lists resulted from thorough searches of the literature and of herpetological collections databases, and from surveys on the islands conducted between March 2009 and January 2011. Currently there are 49 species of anurans distributed in 10 families recorded for these islands and this number accounts for c. 90% of the diversity present in the nearby mainland areas. Although Hylidae represents more than 40% of the species recorded on the islands, Thoropa miliaris (Cycloramphidae) is the only species present on all islands. On the islands there are three endemic species and two species listed as threatened by the IUCN. This study has added seven species to the previous list for Ilha Grande and two species to the list for Ilha da Marambaia.

Floristic survey of flagellate green algae (Chlorophyceae and Prasinophyceae) from four water bodies in the state of Rio de Janeiro, southeast Brazil. Samples were collected bimonthly from September 1988 to August 1991. Thirty-five taxa of which 31 in Chlorophyceae (24 Chlamydomonadales and seven Volvocales) and four in Prasinophyceae (Polyblepharidales) were identified. Twenty-three taxa are new records for Brazil and 31 are registered for the first time for Rio de Janeiro State. On basis of cell shape, location of the nucleus and degree of longitudinal striations on the chloroplast surface a new combination, Vitreochlamys lefevrei (Bourr.) Menezes & C. Bicudo, is proposed. Integrating studies among morphological analysis on natural/cultured material and characterizing of reproduction/life cycle as well the correlating between the occurrence of the species and environmental conditions are needed in order to better knowledge the degree of phenotypic plasticity within the members of the flagellate green algae in the country.

We report the first record of Sterna dougallii Montagu, 1813 on the southeastern Brazilian coast. During monthly bird surveys in the northern Rio de Janeiro State, on January 2012 we recovered a tern banded in Massachusetts, USA. The present record stretches the S. dougallii southernmost geographic distribution in Brazil (Bahia state) by about 600 km. It is difficult to evaluate this species’ regional status due to the absence of continuous sampling efforts.
