Productivity, nutritional quality and phenotypical stability of varieties of silage sorghum in Uberlândia, MG

Sorghum (Sorghum bicolor (L.) Moench) is a good alternative for silage, especially in places with water scarcity and high temperatures, due to their morphological and physiological characteristics. Proper management contributes both to productivity and to the quality of forage. The present study was conducted with the following objectives: To evaluate the agronomic and bromatological performance of varieties of sorghum...

Performance of an improved manual cassava harvesting tool as influenced by planting position and cassava variety

Cassava has become an important food security crop in Ghana over the years and in most parts of sub-Saharan Africa; making it the single most important source of dietary energy. Harvesting, one of the serious bottlenecks in the cassava production value chain, has received little attention in terms of mechanisation. Earlier attempts at mechanising cassava harvesting have been challenged mainly by inappropriate method of...

Peat influence on Zn tolerance, bioconcentration and bioaccumulation in Eucalyptus grandis Hill ex Maiden

Soil contamination with zinc occurs in mining and agricultural areas through successive applications of pig slurry. Essential to the selection and adaptation of plants to contaminated soil, is the study of species showing not only tolerance but also bioaccumulation or bioconcentration of zinc associated with amelioration. In this context, this study aimed to evaluate the influence of peat addition on the tolerance,...

Radiological hazard of coffee to humans: a comparative study of Arabian and Turkish coffees

Thirty-nine Arabian and Turkish coffee powder samples purchased from various markets in Saudi Arabia were analyzed by High Pure Germanium (HPGe) gamma spectrometry to determine the activity concentrations of the natural and artificial radionuclides 238U, 226Ra, 232Th, 137Cs, and 40K. All samples, (except for two samples of Turkish coffee) were found to contain a high mean content of 40K, ranging from 839.83 to 1197.11...

Effect of seed desiccation and sucrose concentration on the in vitro establishment of mangabeira (Hancornia speciosa Gomes var. gardneri) seedlings

Mangabeira (Hancornia speciosa Gomes var. gardneri) is one of the most important fruit trees in the cerrado biome, its fruits being highly valued both for in natura consumption and for processing. Although its seeds are delicate, losing viability within a few hours after collection, seeds still represent the predominant tool of propagation multiplication of this species, since the plant encounters limitations in the...

Physiological and agronomic characteristics of cassava genotypes

This experiment was conducted with the objective of evaluating physiological and agronomic characteristics of cassava genotypes in the municipality of Cândido Sales, State of Bahia, Brazil, between October 2010 and August 2012. Complete randomized block design was used, with three replications and 28 treatments formed by genotypes Amansa Burro, Aramaris, Bom Jardim, Bromadeira, Caipira, Caitité, Caravela,...

Spatial patterns of soil attributes in a fluvent in the semiarid region, Brazil

Spatial variability studies on soil attributes are fundamental for adoption of best agricultural practices concerned with irrigated agricultural sustainability. This study aims to infer the spatial variability patterns of soil moisture, soils salinity and soil texture in an irrigated area of Pernambuco State (Brazil) under cultivation of carrot (Daucus Carota L.), during the dry period of 2012. The area is a typical...

Rooting inducers and organic substrates in the propagation of 'Paluma' guava by cutting

To produce seedlings with quality is one of the factors that mostly contribute to increase the production chain of a fruit crop. The use of organic substrates in the production of seedlings becomes a way to reduce costs by using raw material available regionally. Then, the aim of this study was to evaluate the influence of rooting inducers and the contribution of organic substrates to improve the rooting of herbaceous...
