Boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), trapping and pheromone quantitative analysis of extended-life pheromone lures manufactured with 0, 10, 20, and 30 mg of eugenol was conducted in the Rio Grande Valley of Texas under spring and summer conditions. Boll weevils responded positively to eugenol on one of 12 trapping weeks when densities were high, but when ...
in order to evaluate the effects of drought stress and planting method on yield and yield components of two chickpea cultivars (cicer arietinum l.), an experiment was carried out at the research field of faculty of agriculture; shiraz university, using a split factorial randomized complete block design with four replications. the main factor was irrigation stop at different growth stages of chi...
Traditional mulch material (farmyard manure) has long been used in agriculture. However, recent developments have also introduced the scientific community and farmers to advanced chemicals such as potassium polyacrylamide (KPAM), which revolutionised concept of soil water-holding capacity many compared with other materials being used. To compare effect different organic inorganic amendment unde...
The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a serious pest of cultivated cotton, Gossypium hirsutum L., in the Americas, and reinfestation of zones from which they have been eradicated is of perpetual concern. Extensive arrays of pheromone traps monitor for reintroductions, but occasionally the traps collect nontarget weevils that can be misidentified by ...
Drought is considered as the most important constraint to world’s crop production. Furthermore arid and semiarid climate accounts for nearly most of terrestrial areas of Iran. Therefore in order to study the effect of irrigation regimes on growth, physiological attributes and grain yield as well as components of such a crop plant as safflower a 4-replicate split plot RCBD field study was perfor...
For evaluation of spring wheat cultivars using drought resistance indices, two separately experiments were done in split plot basis of Random Complete Block Design with four replications. This research was done with complete irrigation (control) and drought stress that start before and after of booting stage in research farm of Agriculture Faculty, University of Tabriz. Basis grain yield in irr...
Abstract The higher water consumption in the flooding irrigation system has challenged rice cultivation. Applying management techniques that help to save and increase productivity is necessary deal with shortage. We evaluated growth, yield, consumption, responses genotypes techniques. experiment was arranged a split-plot design three replications at Rice Research Institute of Iran, Mazandaran. ...
this study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of black cumin (nigella sativa l.) at the experimental station of the research institute of forest and rangeland, damavan region, iran. a split-plot experimental design, based on randomized complete block design (rcbd) with three replications, was used. i...
in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...
Using water and fertilizer management at the farm level can be increased water use efficiency and reduce the volume of drainage water, fertilizer losses, and other pollutants in farmland with deep underground drains such as Khuzestan agro-industrial Companies. In the present study, a comprehensive simulation model for the water cycle and the nitrogen dynamics modeling was used for water and fer...
