Influence of variable mixing rates and nitrogen fertilization levels on the fodder quality of Egyptian clover (Trifolium alexandrinum L.) and annual ryegrass (Lolium multiflorum Lam.)

Mixing grasses with legumes for forage production has been a common cropping system, especially in the Mediterranean countries. However, the nutritive value of the end product is greatly dependent on adopting the suitable cultural practices to achieve maximum benefit from the forage mixture, especially the nitrogen (N) fertilizer level and the mixing rate. Thus, the current study was carried out on the winter season of...

Genetic variability of Fusarium solani and Fusarium oxysporum f. sp. passiflorae isolates from Pantanal, Amazon and Cerrado biomes of Mato Grosso, Brazil

Soil fungi, Fusarium solani and Fusarium oxysporum f. sp. passiflorae are among the pathogens of greatest economic importance to the passion fruit culture. Little is known about the genetic variability of these pathogens from different regions. The genetic variability of F. solani and F. oxysporum f. sp. passiflorae isolates from Pantanal, Amazon and Cerrado of Mato Grosso State, Brazil, was studied with the help of...

Effect of inactivated yeast on rumen dry matter degradation and fermentation of low concentrate feed

Life yeast is known to improve rumen fermentation characteristics and performance, especially with high concentrate diet, while reports on inactivated yeast are ambiguous. Therefore, the present study focused on short-term effects of inactivated yeast (Levabon®) with an inclusion rate of 0 or 50 g per head per day on in situ rumen dry matter degradability (ISDMD) of a total mixed ration (66.6% grass silage, 14.5%...

Vertical distribution of lead (Pb) in farmlands around contaminated goldmine in Zamfara state, Northern Nigeria

Anthropogenic activities such as artisanal gold mining have been shown to contaminate soils. When these soils are cultivated, lead (Pb)-related human health risks are expected consequent to consumption of crops produced from such soil. This study was conducted with the aim of determining the vertical distribution of Pb in Pb-contaminated farmlands around contaminated goldmine. Eight soil profile pits were dug 1 m deep...

Foliar diagnosis in Phalaenopsis orchid plants subjected to application of nitrogen

Production of orchids is important in floriculture, and nitrogen is one of the nutrients most required by plants. However, there is little information on nitrogen leaf analysis of these orchids. We evaluated the nitrogen fertilization on leaf nutritional status and on the production of dry mass and develop a diagnostic sheet for the orchid Phalaenopsis. Five concentrations of N (0.0, 0.068, 0.136, 0.204 and 0.272 g L-1)...

Socio-economic reasons for high weed infestations in Northwestern Benin maize (Zea maize L.) production systems

Right timing of weed control is one of the most important challenges farmers in North Benin are facing. Weed infestation rates in maize production in the dry savanna zone in Northwestern Benin are often very high causing significant yield losses. The aim of the study was to determine reasons for late weed control in maize, which is the dominating crop in this area. A survey was conducted among 100 representative farmers...

Yam (Dioscorea spp.) responses to the environmental variability in the Guinea Sudan zone of Benin

This study analyzed the morphological characteristics and agronomic potentials of yam varieties (Dioscorea spp.) collected across the Guinea Sudan transition zone of Benin. Dioscorea cayenensis - D. rotundata varieties were characterized as wingless; some varieties were spineless, others had few or dense, robust or thin, and short or prickled spines. There was variation in leaf shape, stem and leaf colour, tuber shapes...

Analysis of vibration levels in agricultural tractor with and without cabin

The use of tractors is indispensable and essential to the agriculture. However, despite being efficient machines, tractors may fail in their projects, leading to the appearance of vibrations in different parts of their structure. Many studies show that the daily exposure to high levels of vibration, these are a risk factor for the health of the whole human body. In view of that, the purpose of this study was to evaluate...
