Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four accessions of cherry tomatoes...

climatechange and the subsequent requirements to comply with environmental standards, continuoustechnological change, need adapt it, adjust, remain competitive. The COVID-19 pandemic economic hardship it brought about, followed by current energy crisis,make imperative address issues of competitiveness efficiency farm units. Theseunfavorable developments particularly affect mountainous disadvant...

We present Sapporo, a library for performing high-precision gravitationalN -body simulations on NVIDIA Graphical Processing Units (GPUs). Our library mimics the GRAPE-6 library, and N -body codes currently running on GRAPE-6 can switch to Sapporo by a simple relinking of the library. The precision of our library is comparable to that of GRAPE-6, even though internally the GPU hardware is limite...

The control of highly infectious diseases of livestock such as classical swine fever, foot-and-mouth disease, and avian influenza is fraught with ethical, economic, and public health dilemmas. Attempts to control outbreaks of these pathogens rely on massive culling of infected farms, and farms deemed to be at risk of infection. Conventional approaches usually involve the preventive culling of a...

Building-Integrated Agriculture (BIA) in urban areas is claimed to be environmentally sustainable vis-à-vis conventional commercial agriculture practices by reducing food miles, minimizing land and water use and improving yields. However, as it is operated in controlled indoor environments, BIA can be highly energyintensive. In order to better understand the influence of local foodshed characte...

abstract the production unit size is one of the effective factors in optimum uses of inputs. since optimum size is affected by the characters and economical conditions in each district, the studies for determining the optimum farm size should be done specially for each crop and each district. in this study tried to determine the optimum rice farm size in guilan province which is one of the most...

BACKGROUND Porcine reproductive and respiratory syndrome (PRRS) is one of the most economically devastating infectious diseases for the swine industry. A better understanding of the disease dynamics and the transmission pathways under diverse epidemiological scenarios is a key for the successful PRRS control and elimination in endemic settings. In this paper we used a two step parameter-driven ...

introduction: maintaining soil moisture content at about field capacity and reducing water loss in near root zone plays a key role for developing soil and water management programs. clay pot or porous pipe is a traditional sub-irrigation method and is ideal for many farms in the world’s dry land with small and medium sized farms and gardens and is still used limitedly in dry lands of india, ira...

rashe grape cultivar grows in kurdistan province in rain fed conditions. microclimate conditions have a great effect on grape berry quality. information about changes in grape berry composition in the relation to climate changes is limited. in order to measure the effects of slope and altitude on some grape berry chemical composition, a study was conducted on grape cv. ‘rasheh’ in university of...
