Is silicon capable to affect the photosynthetic performance of green maize plants?

Green maize (Zea mays L.) is a cultivated species of significant importance in the agricultural scene. The literature reports that Si has been used as an alternative option for sustainable agricultural systems. We examined the hypothesis that this beneficial element will improve the photosynthetic performance and biological productivity of crop plants, under field conditions, without nutritional stress. In this context,...

Genetic variability of yam based on quantitative descriptors

Yam is a promising income source for small producers in the Recôncavo Baiano region. However, few genetic studies have been conducted with this culture. In this sense, the aim of this study was to assess genetic variability among 89 genotypes of yam (Dioscorea rotundata Poir.) collected in four municipalities in Bahia State, Brazil. These were assessed based on eight quantitative descriptors. Data were subjected...

Physiological responses of operators to handle vibration of diesel-fueled single-axle tractor

Hand-arm transmitted vibration originating from a 15 horsepower single-axle tractor can be very strong and cause operator fatigue plus various physiological disorders in vascular, neurological, and musculoskeletal systems. The objective of this work was to measure the characteristics of such hand-transmitted vibrations and its effect on the health of the single-axle tractor operator, in a research program conducted at...

Physiological potential of lettuce seeds crespa

The present work aimed to evaluate the germination, emergence, vigor and initial development of lettuce (Lactuca sativa L.) cultivars. Nine cultivars belonging to the crespa group, Cinderella, Monica SF 31, Mimosa (Salad Bowl), Veneranda, Brava, Cerbiatta (Catalonha), Itapua Super, Itaúna Prisée, Simpson and Vitória de Verão were used. The experiment was conducted to ensure the accuracy of...

Changes in livelihood strategies and animal husbandry practices of pastoralists in the sub-humid zone of West Africa

Migration to and sedentarization in the sub-humid zone of Burkina Faso has become a major adaptation measure of Sahelian pastoralists to the severe droughts and in response to a rapidly changing socio-economic environment. This study is aimed at assessing livelihoods and livestock husbandry practices as a consequence of pastoralist sedentarization. The study sites were located in the Sudano-Sahelian and Sudanian zone of...

Comparison of proximate, mineral and phytochemical composition of enset (Ensete ventricosum (Welw.) Cheesman) landraces used for a different purpose

Enset (Ensete ventricosum (Welw.) Cheesman) is one of the oldest cultivated food security crops in Ethiopia. There are a number of enset landraces used for traditional medicine. These landraces are believed to have better minerals and phytochemical compositions, which are not proved scientifically. The objective of this study was to compare the proximate, mineral and phytochemical compositions of corms of enset...
