rust caused by phakopsora pachyrhizi syd. is a major constraint to soybean product in asia. early detection and possibilities of controlling plant diseases by the integration of several image processing methods has been the subject of extensive research. the main contribution of this paper is to present different methodologies for quantitatively detecting soybean rust at each stage of disease d...

A split-split-plot design with three replications in two years of 2009 and 2010 was conducted to investigate the effect of different levels of irrigation water (main plot), salinity of irrigation water (sub-plot) and nitrogen fertilizer rate (sub-subplot) on maize growth rate and gas exchange. Irrigation treatments were I1 (1.0 crop evapotranspiration (ETc)+0.25ETc as leaching), I2 (0.75I1)...

in order to study the sensitivity of vegetative growth to water deficit stress of a late-maturing peach (prunus persica l. cv. elberta) under orchard conditions, an experiment was conducted as randomized complete-block design with three treatments and four repetitions in shahdiran commercial orchard in mashhad during 2011. three irrigation treatments including 360 (low stress), 180 (moderate st...

Abstract This research was conducted in Toroq Experimental field station, Mashhad, Iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. Moisture stress treatments (at seven levels) were assigned to main plots, including: D1 ( full irrigation), D2 (no irrigation from one-leaf to double ridge) st...

activity of fresh neem leaf juice to immobilize, anaesthetize and fatal effect were studied against two live fish species, anabas testudineus and channa punctatus. the concentrations, 5, 10, 15 and 20% of neem leaf juice affected both the species, but a.  testudineus was found to be comparatively more susceptible to the treatment  than c.  punctatus . the time required to immobilize were 4 to >...

Leaf rust (caused by Erikss. []) is increasingly impacting durum wheat ( L. var. ) production with the recent appearance of races with virulence to widely grown cultivars in many durum producing areas worldwide. A highly virulent race on durum wheat was recently detected in Kansas. This race may spread to the northern Great Plains, where most of the US durum wheat is produced. The objective of ...
