Nitrogen and sulfur absorption by quality protein maize (QPM) maize as affected by interaction between nitrogen and sulfur fertilizers at Samaru, Zaria, Nigeria

Field trials were conducted in 2006, 2007 and 2008 wet seasons, at the Institute for Agricultural Research Farm, Samaru in the Northern Guinea savanna of Nigeria to determine the effect of interaction between Nitrogen and Sulfur fertilizers on up-take of Nitrogen and Sulfur by quality protein maize (QPM). Treatments consisted of four rates each of nitrogen (0, 60,120 and 180 kg N/ha) and sulfur fertilizer (0, 5, 10 and...

Modelling crown volume in Acacia mearnsii stands

The aim of the present study was to model the crown volume in black wattle stands (Acacia mearnsii De Wild.) in Rio Grande do Sul, Brazil. The study was carried out in plots installed in black wattle stands in area where the plantations of the species are common. Two trees in each plot of average diameter were felled to determination total height, crown length (crown height) and crown width taken twice, each measurement...

Effect of silicon fertilization on mineral composition of rice under Typic Ustochrept soils

A pot experiment was conducted in 2012 in the greenhouse of the Anand Agricultural University Anand Gujarat, India. Treatments were arranged in a factorial completely randomized complete design with silicon factor at four levels (0, 100, 200 and 300 ppm) with three replicates. Indian improved and high -yielding variety Gurajari was used. The Si application up to 200 mg kg-1 soil significantly increased grain and straw...

Dry season bean production at different sowing dates under the South Minas Gerais conditions, Brazil

The agro-climatic zoning classifies the southern region of Minas Gerais, Brazil, as being suitable for bean farming, especially in the dry season, where there are appropriate climatic conditions for growing. In this area, determining the optimum sowing dates is controlled by the climatic conditions and the adaptability of different cultivars. Therefore, the aim of this study was to evaluate the agronomic characteristics...

Isolation and characterization of Bacillus thuringiensis (Ernst Berliner) strains indigenous to agricultural soils of Mali

The objective of this work was to isolate and characterize Bacillus thuringiensis from agricultural and other insect breeding sites in Mali. A hundred soil samples were collected from Bamako district, Segou, Sikasso and Timbuktu regions. B. thuringiensis (Bt) was isolated from the samples using a heat-acetate method and the isolates were identified and classified using morphological and biochemical tests. The frequency...

Damage in maize ears associated with methods of inoculation of Stenocarpella maydis

This study aimed to find an efficient method of inoculation of Stenocarpella maydis to produce white ear rot (WER) and estimate pathogen damage on maize grain yield components. Measured components were ear mass, grain mass per ear, and thousand grain weight. The experiments were performed in Ponta Grossa, PR, Brazil in a randomized block design with treatments arranged in a split plot with three replications. Three...

Willingness to pay for rainfall risk insurance by smallholder farmers in Central Rift Valley of Ethiopia: The case of Dugda and Mieso Districts

Current climate variability is already imposing significant challenge. Therefore, farmers have faced income variability in almost every production season. Problems associated with dependence on rain fed agriculture are common in Ethiopia. Smallholder farmers’ vulnerability from such income variability is also common. Over the years, a range of risk management strategies have been used to reduce, or to assist...

Comparison between manual and semi-mechanical harvest of coffee fruit in mountainous areas

In the coffee production, the most expensive operation is the harvest, mainly by lack the labor this time of year. In regions of large and flat areas, the use of mechanization allows a good reduction in the production cost. In mountainous areas the coffee harvest is performed manually. With the aim of reducing production costs, there has been a continuous increase in the use of machinery, especially at harvest. In...

Carcass quality audit - A strategy to improve beef sector in Ethiopia

Ethiopia has the largest cattle population in Africa. However, the potential of the sector has not fully utilized. Average carcass weight of cattle, per capita meat consumption and annual volume of meat produced were very low. Experience from developed countries indicates that implementing carcass quality audit would aid to identify quality problems, develop strategies and establish an educational plan to improve...
