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...

Length of the growing season for dry rainfed farming under Monsoon climate in Gedarif, Sudan
Reliable information on the starting and ending of growing season as well as its length will greatly assist in appropriate planning for rainfed agriculture farming practices. The objective of this study is to determine the start, end and length of growing season, based on dependable rainfall during wet (20%), normal (50%) and dry (80%) years, which were retrieved from historical rainfall records analysis of seven...

Agronomic efficiency, yield and yield components of food barley response to nitrogen rates after fababean in Emba Alaje, Northern Ethiopia
This study was initiated to investigate the effect of nitrogen fertilizer on agronomic efficiency, yield and yield components of barley after faba bean precursor crop. A field experiment was carried out in 2015 main cropping season at district at Ayba and Tek’a kebeles in Tigray Regional State, Ethiopia. The experiments were arranged in a randomized complete block design with three replications....

Water and soil conservation techniques and food security in the northern region of Burkina Faso
Food insecurity is a major challenge facing the rapidly growing population in the sub-Saharan Africa and it is a common feature in the northern region of Burkina Faso. The focus of this study was to investigate the prevalence of food insecurity in the northern region of Burkina Faso after many years of implementation of water and soil conservation techniques. A survey was carried out in six villages in the Northern...

Strategic planning of regional oil-and-fat subcomplex of Russia
The purpose of the work is to analyze the trends in the development of the oil-and-fat subcomplex as one of the most important components of the agribusiness of the Russian Federation, and state policy in the strategic planning in this sphere. The materials of the United States Department of Agriculture, the State Statistics Service and the Ministry of Agriculture of the Russian Federation served as the information...

Evaluation of diazotrophic bacteria from rice varieties (Oryza sativa L.) grown in Rio de Janeiro State, Brazil
The indiscriminate application of nitrogen fertilizer in order to increase rice crop productivity contributes to environmental degradation. One of the possible alternatives to ease up this problem is the use of sustainable and cost-effective technologies such as biofertilizers to promote plant growth. This work aimed to isolate, characterize and select diazotrophic bacteria associated with rice cultivars EPAGRI-109 and...

Agricultural productivity, land use and draught animal power formula derived from mixed crop-livestock systems in Southwestern Ethiopia
The interaction of agricultural land cover area between land use systems and level of household income was identified. The annual cropland area was significantly higher than the natural pastureland and perennial cropland. The difference in household income earned was not significant between the annual crop and livestock. Such a difference however is not surprising because smallholder land system is a dual asset, and...
