An empirical assessment of women’s access to land and credit in North West Province, South Africa: A probit analysis

  This study investigates women’s access to land and credit in Disobltla, North West Province. Land is an important resource for the survival of rural women. A probit model was used to analyse the factors influencing both access to farming land and credit, based on cross-sectional data collected from a sample of 82 women. The findings show that access to farming land is influenced by variables, the...

Wheat genotypic variability in utilizing nitrogen fertilizer for a cooler canopy under a heat-stressed irrigated environment

  Canopy cooling in dry heat-stressed areas is regarded as one of the most physiologically efficient way to attain high grain yields in wheat. Twelve wheat genotypes were grown with four N levels in a 2-year field trial to investigate their efficiency to utilize addition of nitrogen for canopy cooling and high chlorophyll accumulation under a dry but irrigated hot environment in Sudan. Both canopy temperature...

Evaluation of microbial inoculants as biofertilizers for the improvement of growth and yield of soybean and maize crops in savanna soils

  Certain rhizobacteria exert considerable influence on plant growth and development, particularly under limiting conditions. The effects of some indigenous soil microbial isolates and commercially produced microbial inoculants, referred to as bio-inoculants, on the growth and dry matter yield (DMY) of maize (Zea mays) and soybean (Glycine max) crops were assessed under greenhouse conditions. In two sets of...

Nematode biodiversity in a semi-arid pasture under different grazing regimes

  The study was conducted to explore the influence of over-grazing and ungrazing on nematode biodiversity in a semi-arid region pasture, in Adıyaman, Turkey, in 2008.  Soil samples were taken in mid spring from a pasture that was previously divided into two sites, one is protected by fencing and the second is open to grazing, freely. Nematodes were extracted and allocated to trophic groups and both sites...

Estimation of herd-basis energy status in clinically healthy Holstein cows: Practical implications of body condition scoring and shortened metabolic profiles

  The objective of the study was to estimate herd-basis energy status (ES) using body condition scoring (BCS) and shortened metabolic profiles in multiparous clinically healthy dairy cows and to evaluate if such profiles can be informative in herd investigation to indicate on metabolic herd problems. A total of 180 Holstein cows from commercial herd were clinically examined and assigned to one of 3 equal...

The influence of feeding plant oils on milk production and fatty acid content

  This investigation was done to research the effects of vegetable oils on UFA content in milk fat and performances of high-yielding lactating cows. Sixteen lactating Holstein cows in early lactation were used in a complete randomized design. Experimental diets included: 1) Control (without oil, CON); 2) Diet with 2% soybean oil (SBO); 3) Diet with 2% sunflower oil (SFO); and 4) Diet with 2% canola oil (CLO)....

DNA purification and isolation of genomic DNA from bacterial species by plasmid purification system

  We have successfully adapted the Wizard® MagneSil™ plasmid DNA purification system to isolate genomic DNA from soil bacteria strains important in research and the agricultural industry. In this work, we describe the modified protocol for isolating genomic DNA from soil bacteria using manual and automated approaches on the Biomek® 2000. The isolated genomic DNA was then used to PCR amplify an 875...

Mechanisms of food partitioning and ecomorphological correlates in ten fish species from a tropical estuarine marine protected area (Bamboung, Senegal, West Africa)

  Ecomorphological correlates were sought among 10 fish species of different life history traits in a tropical estuary. Results from gut contents analysis showed that fish species were classified into four trophic groups including detritivores, zooplanktivores, benthivores, piscivores and macrocarnivores. Resource partitioning among fishes was under the influence of their morphological attributes. Detritivores...

Hierarchical temporal memory for mapping vineyards using digital aerial photographs

  The responsibility to manage vineyards in the European Union belongs to a large range of organizations, which need detailed information about geographic data. For this purpose, most member states have developed vineyard registers. This paper has explored an inferential system for vineyard detection using digital aerial photographs. The system has been inspired by a recent memory prediction theory...

Salinity-alkalinity tolerance in wheat: Seed germination, early seedling growth, ion relations and solute accumulation

  Germination and early seedling growth are the most critical stages for plant establishment in saline-alkaline soil. To gain a better understanding of relations between germination and seedling establishment, and the physiological adaptive mechanisms of the two stages under salt and alkali environments, wheat was tested by mixing two neutral salts (NaCl:Na2SO4) and two alkaline salts (NaHCO3:Na2CO3). Results...

Effect of moderately-high temperature stress on photosynthesis and carbohydrate metabolism in tomato (Lycopersico esculentum L.) leaves

  Changes in the production and metabolism of photosynthate in tomato leaves were investigated after plants were treated to moderately high temperature stress for 8 h. Plants grown continuously at 25°C served as the controls. Compared to the controls, photosynthetic activity decreased in plants exposed to 35°C for ≥2 h. The net rate of photosynthetic (Pn) and the limitation of stomatal conductance...
