Infection, colonization and growth-promoting effects of tea plant (Camellia sinensis L.) by the endophytic bacterium Herbaspirillum sp. WT00C
The endophytic Herbaspirillum sp. WT00C, isolated from tea plant, seems to have a potential ability to promote tea-plant rooting and budding due to its capability of producing indole-3-acetic acid (IAA), ammonia and siderophores. Thus, the present study was aimed to verify whether this bacterium could be used for tea cultivation as an environment-friendly bioaccelerator. To evaluate its potential use in promoting...

Evolution and impacts of groundnut research and development in Malawi: An ex-post analysis
Groundnut is currently the second income earner for smallholder farmers in Malawi, and an inexpensive source of balanced protein. Owing to the continued crop improvement research and extension efforts, production has risen by more than 15 times in the past two decades. Despite the dramatic growth, no impact assessment has ever been conducted to date. This study aims to assess the economic impacts of investments in...

Tomato (Solanum lycopersicum) hybrid Hermosa indeterminate study of yield and fruit quality under greenhouse conditions responding at organic manure application
The organics alternatives in the vegetables production are a strategy to produce free chemical polluted foods that endanger human health. In the present study, the Hermosa indeterminate tomato variety was used and the following treatments were evaluated in a completely randomized design: Compost 2 tons/ha + VAM and BAC + Compost tea 50% (Treatment 1), Compost 4 tons/ha + VAM and BAC + Compost tea 50% (Treatment 2),...

Treatment of sewage sludge with the use of solarization and sanitizing products for agricultural purposes
Recycling of sewage sludge for agricultural purposes is recommended as one of the most adequate forms of final disposal of this waste. This study evaluated the effectiveness of solarization combined with chemical treatments by acid and alkali during different periods of cleaning. The experiment was conducted at the Experimental Farm of the Federal University of Uberlândia (UFU) in Uberlândia-MG. The...

Correlation of viral load with lesion severity in field pigs affected with porcine circovirus type 2
Porcine circovirus type 2 (PCV2) is an important infection factor causing post weaning multisystemic wasting syndrome (PMWS). The amount of PCV2 viral load may mainly give rise to clinical symptom and pathological lesion of PMWS. In order to investigate the relationship between PCV2 viral load and the lesion severity of lymph tissues, and search further for some clues of pathologic diagnosis of PMWS, thirty pig cases...

Nitrogen metabolism in sorghum under salinity and silicon treatments in Brazil
The objective of the present research was to study nitrogen metabolism in sorghum plants subjected to salt stress and silicon concentration. The experiment was conducted at the Amazon Federal Rural University, Capitão Poço Decentralized Unit for 1 month, in 2013, using the cultivar BR 700 of forage sorghum plants (Sorghum bicolor [Moench.]). The experimental design was completely randomized, in a 5 ×...

Quality index method (QIM) and quantitative descriptive analysis (QDA) of Nile tilapia (Oreochromis niloticus) quality indices
The aim of this study was to develop specific criteria for evaluating freshness in farmed Nile tilapia (Oreochromis niloticus), eviscerated and stored on ice, by employing sensorial, physicochemical and bacteriological analyses. Sensorial analyses were composed of quantitative descriptive analysis (QDA) for cooked fish and quality index method (QIM) for raw fish evaluation in samples stored for 22 days. Psychrotrophic...
