to investigate the effect of deficit irrigation and macro and micro fertilizers on morpho-physiological characteristics of satureja a field experiment was conducted in agricultural research station of haji-abad (hormozghan province-iran) a split plot randomized complete block design with three replications during the growing season of 2012-2014. irrigation treatments consisted of normal, modera...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...

The spatio-temporal reinfestation patterns by Triatoma infestans following a blanket insecticide spraying in the rural community of Amama in northwestern Argentina were analyzed using a geographic information system, satellite imagery, and spatial statistics. Domestic and peridomestic reinfestation by triatomine bugs was monitored from 1993 to 1997. Triatoma infestans was detected at least once...

in order to study the effect of foliar zinc spraying on photosynthetic pigments and yield of chickpea under water stress conditions, a factorial experiment carried out based on randomized completely block design (rcbd) with three replications in university of mohaghegh ardabili agricultural research station in 2012. the treatments consisted of three levels of irrigation (irrigated at planting, ...

Historical records and archaeological discoveries have shown that prosperous agricultural activities developed in the ancient Juyan Oasis of northwestern China, an important oasis that once flourished on the ancient Silk Road. However, how the irrigation canals were distributed in historical time was unknown. Here, we identified and mapped the spatial distribution of ancient abandoned irrigatio...

In this paper, the babbitting of a bearing in boiler feed pump of an electromotor has been studied. These bearings have an important role in reducing the shut down times in the pumps, compressors and turbines. The most conventional method in babbitting is casting as a melting method. The comparison between thermal spray and casting methods in babbitting shows that the thermal spraying babbitt l...

Depriving homing pigeons of olfactory information by spraying an 18% zinc sulphate solution onto their olfactory ephithelium results in anosmia that persists for at least 5 days (tested using the ‘orienting response’). To study whether anosmic zinc-sulphate-treated pigeons (ZnSO4-pigeons) were able to compensate for their loss of olfactory information by using familiar landmarks, we made releas...

Background & Aims of the Study: Grape, a crucial agriculture crop of Malayer city, is affected by Vine cicada, Psalmocharias alhageos.  Imidacloprid, a neonicotinoid insecticide, provides a good management of this insect. The aim of this research is residue persistence study of imidacloprid on grapes, to estimate its residue deposit, the half-life of degradation and safe pre-harvest consumption...
