An estimation of import demand function for wheat in South Africa: 1971-2007

In the 1980s, South Africa was self-sufficient in the production of all important field crops, except rice. Currently, South Africa is a net importer of wheat, even though the country has managed to maintain average agricultural production above the population growth rate; some agricultural commodities are lacking and need to be imported. Using double logarithmic linear function and data obtained from secondary sources,...

Factors effecting longer term farm contracts in the frozen fries processing industry

Prices are highly volatile in the South African potato industry and the marketing of potatoes are associated with high transaction costs. Most potatoes produced for the processing industry in South Africa are still under short-term contracts. The processors of frozen fries in South Africa want producers to enter into long-term contracts in order to reduce uncertainty and transaction cost. The aim of this paper was to...

Microcredit scheme impact and food security status of beneficiaries in Kaduna State, Nigeria: A propensity score matching approach

The prevalence of food insecurity has been generally reported to be higher in the rural areas of Nigeria, despite the fact that the bulk of food production takes place there. This study used the Food Security Index (FSI) and Propensity Score Matching (PSM) to evaluate the impact of the United Nations Development Programmes’ (UNDP) micro credit scheme on the food security status of farm households in three Local...

Influence of crop management systems on soil properties and sorghum yields in the Sahelian zone of Mali

Better land and crop management systems are needed to resolve actual problem of land and environmental degradation in Africa. Assessment of required technology must consider both impacts on crop yields and the different environmental compartments (soil, water and atmosphere). With these concerns, an experimental study was conducted on these basis at Cinzana research station (13° 15’N; 5°...

Effects of mowing disturbance on the community succession of typical steppe in the Loess Plateau of China

Research based on Stipa bungeana community enclosing typical steppe zone in the Loess Plateau, and through different intensity-mowing disturbance test for 27 years, shows that higher species diversity and productivity are retained for grassland through moderate mowing, promotion of substance balance, starting cycle and providing an important basis for reasonable mowing and using the enclosed grassland. Due to...

Notes on selenium in mushrooms data determined by inductively coupled plasma atomic emission spectroscopy (ICP–AES) and hydride generation atomic absorption spectroscopy (HG–AAS) techniques

This manuscript discusses the credibility of the selenium in mushroom data generated using inductively coupled plasma atomic emission spectroscopy (ICP–AES) compared to that from hydride generation atomic absorption spectroscopy (HG–AAS). Selenium (Se) was determined by two methods: one was the widely applied and well validated hydride generation atomic absorption spectroscopy (HG–AAS) that was a...

Protein concentration and amino acid composition in grain amaranth (Amaranthus cruentus L.) as affected by sowing date and nitrogen fertilization

A four-year field experiment was used to evaluate the effects of sowing date and nitrogen fertilization on protein content and amino acid composition of grain of amaranth (Amaranthus cruentus L.). Seeds of A. cruentus cv.'G6' were sown at two sowing dates (May and June) and fertilized at rates to obtain three target levels of available soil mineral nitrogen (Nmin) set to 140, 200 and 260 kg N...

Sensory evaluation response as a selection tool in African eggplant (Solanum aethiopicum) production and breeding

Garden egg also known as African eggplant is one of the most important vegetables that is widely cultivated across the African continent especially in West and East Africa. Sensory evaluation of the eggplant fruits as a selection tool for eggplant breeding was carried out at the Crop physiology laboratory of the Department of Crop Science, University of Nigeria, Nsukka, Nigeria. Four cultivars of eggplant, namely: Pink...

Characteristics and polymorphism of NAM gene from Aegilops section sitopsis species

In this study, 11 novel NAM alleles were cloned from five species of Aegilops section sitopsis. These nucleotide sequences ranged from 1,540 to 1,555 bp with 3 exons and 2 introns. Their coding proteins contained both N-terminal nitrogen assimilation control (NAC) domain with 5 sub-domains and C-terminal transcriptional activation region (TAR). They have high identities and the closest homology...

Spatiotemporal yield loss assessment in corn due to common rust caused by Puccinia sorghi Schw

A field experiment was carried out in deep black soil at Main Agricultural Research Station, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka during kharif 2010, under rain-fed condition. The yield losses due to common rust were found directly related to disease severity. The avoidable yield losses due to disease were in the range of 11.75 to 60.53% in different spray schedule....
