In Washington, over fifty percent of the wheat produced under rainfed conditions receives less than 300 mm of annual precipitation. Hence, a winter wheat-summer fallow cropping system has been established to obtain adequate moisture for winter wheat production. Current tilled fallow systems receive significant soil erosion through both wind and water. As a result, no-till chemical fallow system...

This study analyzes the structure and composition of ant communities in citrus orchards in Catalonia (northeast Spain) and compares them with the ant fauna found in natural communities of the region. In the citrus orchards considered in this study, the most abundant species were Lasius niger and Pheidole pallidula, which are behaviorally dominant species. Two other dominant species, Linepithema...

dry drainage could be considered as a natural system which evaporates water from fallow areas to control water table depth and soil salinity in neighboring cropped area. the technique requires the retirement of part of the irrigated land. one of the most notable design criteria for this system is to estimate the ratio of cropped to fallow strip width. a plexiglas physical model with the dimensi...

In northern Laos, rapid population growth and government policies to reduce the area under slash-and-burn systems have resulted in increased cropping intensity, which has increased weed pressure and reduced yields of upland rice. Promising alternative cropping systems include the use of weed-suppressing and multi-purpose legumes as short-term fallow crops. In this study, Stylosanthes guianensis...

The article tackles the impacts of anthropogenic load on physical and hydrophysical soil properties. In order to better comprehend processes spontaneous sylvatisation in a mountain region (the Pohartsi boundary, Koziova village, Skolivski Beskydy physiographic region) four study plots were selected representing successional sequence: forest → pasture hay meadow arable lands. Land patches that a...

The conflict between humans and wildlife is a global issue in the increasingly shared landscape. Human–Wildlife Conflict (HWC) often viewed as threat to most of rural populace world, crop losses remove household’s food supply, are an economic drain on homestead. In this paper, we study extent damage by wild animals two districts Bhutan: Trashiyangtse Tsirang. We surveyed 431 respondents from in...

Savitribai Phule Pune University is known for its biodiversity in Pune. In the present study, we have analyzed changes which occurred on campus and surrounding area over last 40 years. Of 90 bird species reported Khadki pond 1976, failed to notice 34 2018. A major reason decline diversity could be habitat from low scrub jungle, fallow lands grassland buildings, roads, exotic plantations. Increa...

With the growing recognition of the possibility of global climate change, an increasing emphasis on world food security in general and its regional impacts in particular have come to forefront of the scientific community. Agriculture production of rainfed regions is expected to suffer severe water crisis due to delayed monsoon, uneven distribution of rain as a result of climate change. The impa...

We studied the effect of many years of streptomycin use in apple orchards on the proportion of phyllosphere bacteria resistant to streptomycin and bacterial community structure. Leaf samples were collected during early July through early September from four orchards that had been sprayed with streptomycin during spring of most years for at least 10 years and four orchards that had not been spra...
