Statistical analysis of impact of climate change on crop potentials productivity on a regional scale in Nigeria

Yield improvement is the main aim of all agricultural activities. Therefore, it is important to have an idea about the yield that can be produced from a piece of land before investing in it. This work is aimed at analysing the impact of climate change on crop yield potential and predicting the crop yield potential in six geo political zones in Nigeria using global solar radiation as the only limiting factor of...

Use of artificial neural networks to assess yield projection and average production of eucalyptus stands

Eucalyptus stands growth depends on genotype, age, quality of the local soil and silvicultural treatment. Environmental factors, mainly the water availability to plants throughout the years, temperature and solar radiation are relevant to production capacity. The models used in Brazil to stimulate the future production of forestry stands are those that estimate growth and/or production according to age, basal area and...

Does zinc uptake relate well with differential zinc efficiency of barley genotypes?

To some extent, differential zinc (Zn) efficiency of cereals, particularly differences between species may be attributed to phytosiderophores (PSs) release and inorganic Zn (Zn2+) uptake; however, the discrepancies within a given species are still under discussion. Moreover, studies on the explanations of differential Zn efficiencies of barleys are limited. That is why using two barley (Hordeum vulgare L.) cultivars...

Effect of Anacardium occidentale, Ricinus communis and Spirulina sp. on the diets of broiler chickens

The use of antibiotics as a growth promoter was banned because of residues that are left in animal products. Alternatives to antibiotics that promote animal growth and health without leaving residues in food are being sought. An experiment was conducted to evaluate the effects of a commercial mixture of functional oils and algae (FOA) on growth and gut morphology in broiler chickens. A total of 224 one day-old Cobb male...
