Gene flow is an essential component of population adaptation and species evolution. Understanding of the natural and anthropogenic factors affecting gene flow is also critical for the development of appropriate management, breeding, and conservation programs. Here, we explored the natural and anthropogenic factors impacting crop-to-wild and within wild gene flow in apples in Europe using an unp...

Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...

This paper develops a model to examine the impacts of uncertainty about crop production and irreversibility of program participation on determining land rental payments and least-cost land retirement targeting in the Conservation Reserve Enhancement Program. Results show that under risk aversion only, the marginal cost of abatement and the average land rental payment are less than those under r...

Chenopodium quinoa is gaining global importance due to its excellent protein quality and tolerance of abiotic stresses. The last 60 years have seen major strides in the expansion of quinoa crop production and experimentation. Quinoa's wide genetic diversity has led to its agronomic versatility and adaptation to different soil types, particularly saline soils, and environments with extremely var...

To identify the factors contributing to the farmers’ attitude towards Integrated Pest Management (IPM) practices in rice cultivation, 158 family heads of the Farmers Field Schools (FFSs) at Godagari Upzila under Rajshahi District were chosen at random to constitute the subjects of the study. Data were collected from 5 September, 2006 to 28 January, 2007. Twenty four selected characteristics of ...

Bees are important pollinators of plants in both agricultural and non-agricultural landscapes. Recent losses of both managed and wild bee species have negative impacts on crop production and ecosystem diversity. Therefore, in order to mitigate bee losses, it is important to identify the factors most responsible. Multiple factors including pathogens, agrochemical exposure, lack of quality forage...

Flammulina velutipes is one of the major edible mushrooms in the world. Recently, abnormalities that have a negative impact on crop production have been reported in this mushroom. These symptoms include slow vegetative growth, a compact mycelial mat, and few or even no fruiting bodies. The morphologies and fruiting capabilities of monokaryons of wild-type and degenerate strains that arose throu...

The focus of everyday life in Sugao revolves around farming. Village activity changes with the agricultural season and farm tasks are the rotating pivot around which village society is organized. The agricultural cycle has traditionally been geared, in the Sugao farmer's mind, to the moon and the astrological sign (of which there are twenty-seven in the Hindu calendar) in dominance at the time....

Livestock kept or produced in smallholder farming systems are an important component of the agricultural economy in the developing world. The role of livestock on smallholder farms varies widely, providing draught power for crop production or as a production activity for subsistence needs or market sale under systems ranging from extensive pastoralist to intensive, peri-urban feeder and dairy s...
