To understand the role of relative humidity rate, host genotype, inoculation method and growth stage in epidemiology of bean common blight, two greenhouse experiments were carried out monitoring epiphytic population size of Xanthomonas axonopodis pv. phaseoli (Xap) and disease severity. The result showed significant differences among genotypes, inoculation methods and growth stages for epiphyti...

Wave lensing produces the highest level of transient solar irradiances found in nature, ranging in intensity over several orders of magnitude in just a few tens of milliseconds. Shallow coral reefs can be exposed to wave lensing during light-wind, clear-sky conditions, which have been implicated as a secondary cause of mass coral bleaching through light stress. Management strategies to protect ...
evaluating the performance of irrigation systems by providing the possibility of increasing irrigation efficiency in those systems is an important factor in the field of water resources management. in this study, the performance of three systems were evaluated, including linear move sprinkler irrigation systems in maize, sugar beet and alfalfa fields of magsal agro-industrial company which is l...
abstract in order to evaluate the effects of different depths of irrigation by sprinkler irrigation system on water use efficiency (wue) of new early maize cultivar ksc302, an experiments was carried out in karj during 2006 and 2007. experimental design was split plot based on randomized complete blocks with three replications. main plots were three irrigation levels: 75%, 100% and 125% etc (es...

Hal ini dapat mengakibatkan kehilangan dan pemberian yang tidak sesuai dengan kebutuhan tanaman. Penerapan teknologi sprinkler mampu meningkatkan produktivitas untuk memenuhi Penelitian bertujuan mengetahui penerapan pada pertanian Kecamatan Tarakan Utara Kota Tarakan. terdiri a...
water shortage in the agricultural sector is currently a major challenge in crop production. the more efficient water usage is that which increases yield without increasing water use. thus, a determination of the water-yield relationship is essential. a field study was conducted to examine water-yield relations in three genotypes of soybeans, including optimum irrigation depth, a comparison of ...
system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...
