Foliar application of molybdenum improves nitrogen uptake and yield of sunflower
Molybdenum (Mo) foliar spray may improve the nitrogen acquisition by the plants and increase the crop yield. The effects of Mo foliar spray on nitrogen nutrition, achene yield and yield components of sunflower were investigate in this study. The experiment was carried out on a Rhodic Hapludox in Chavantes, São Paulo, Brazil under conventional tillage system. Treatments consisted of five Mo concentrations [0...

Technical-economical evaluation of a solar water heater with vacuum tubes collector, used in a rural area in Paraná, Brazil
Solar radiation is a source of energy that can be used directly by residences and industries. In this work, the efficiency of a solar collector type all-glass installed in a rural area in Paraná, Brazil, in the winter period, was evaluated. Two daily showers were simulated in three different scenarios, to measure additional electrical consumption used to boost the heating of water. In the first scenario,...

Farmers’ risk perceptions and adaptation to climate change in Lichinga and Sussundenga, Mozambique
In Africa, climate change exerts significant pressure on the agricultural sector. Current changes in climate for most parts of Mozambique have resulted in increased frequency of droughts, dry spells and uncertain rainfall. This has resulted in loss of food production and smallholder farmers are most vulnerable to these climatic disasters as they affect the food security status of the household. Despite an increased...

Enhancing the shelf life of fresh-cut bitter gourd using modified atmospheric packaging
The study of modified atmospheric packaging (MAP) of fresh-cut bitter gourd was taken to extend the shelf life. Low density polyethylene (LDPE) and polypropylene (PP) films with a thickness of 100 micron (µ) were selected due to their less permeability to O2. The fresh-cut bitter gourd packaged under two different atmosphere (active – 3% O2 and 5% CO2 and passive – atmospheric air) and stored at...

Evaluation of different seed dormancy breaking techniques on okra (Abelmoschus esculentus L.) seed germination
Okra (Abelmoschus esculentus L.) is one of the horticultural crops commonly grown in Zimbabwe but the productivity of the crop is hampered by poor erratic seed germination due to dormancy. A study was carried out at Bindura University of Science Education to determine the best method and treatment combination of breaking okra seed dormancy. Viability tests and germination tests were conducted first to ascertain that...
