background and objectives: early watergrass (echinochloa oryzoides) is considered as a new-introduced species and then as a potential invader. investigation of competitive traits of this species, in comparison with barnyardgrass (e. crus-galli), one of the most important weeds in rice fields of guilan province, would be useful to determine its spreading possibility as an aggressive weed. theref...

The efficacy of oxamyl in controlling Heterodera schachtii on cabbage was determined by applying various contbinations of soil drenches at 6.7 kg (a.i.)/ha and foliar sprays at 0.04 kg (a.i.)/100 liters of water to cabbage seedlings. Pretransplant drenches provided some control of H. schachtii over a 13-week period. A single foliar spray of oxamyl 1 week before transplanting apparently prevente...

Onion is a biennial plant that produces bulb. The larger the onion bulb, more valuable it becomes. Therefore, important to study bulb weight and size components affecting it. For this study, four New Mexico State Univ. breeding lines two commercial cultivars, ‘Rumba’ ‘Stockton Early Yellow’, were selected. These cultivars evaluated for height, leaf number sheath diameter, at five different date...

abstract water is a main factor in production of crops. optimizing the usage of water is essential especially in iran which is a dry and semi-dry country. investigation on the effect of different irrigation treatments on chilo suppressalis walker (lep.: crambidae), as the most destructive rice pest, can be an efficient strategy in optimizing usage of water in integrated crop management (icm). i...

Four semi-dwarf rices (Oryza sativa L.) differing in percentage of grain protein, grown in a flooded field receiving basal N fertilization, had a peak activity of root glutamate dehydrogenase 4 weeks after transplanting. A lower peak occurred during panicle formation 10 weeks after transplanting. The percentage of N of the active leaf blades was also highest 4 weeks after transplanting. The act...

To investigate the feasibility of transplanting human neural progenitor cells (hNPCs) to the retina of nonimmunosuppressed pigs, cultured hNPCs were injected into the subretinal space of 5 adult pigs after laser burns were applied to promote donor cell integration. Postoperatively, the retinal vessels appeared normal without signs of exudation, bleeding, or subretinal elevation. Eyes were harve...

Sewage sludge is used as fertiliser and contains nutrients required for plant growth. It also contaminants that can leach into crops. The effects of sewage on kale plants were investigated. Mixture ratios 50:50 20:80 soil prepared. soil-sludge blends analysed selected metal residues. Kale seedlings 10-13 cm planted the different combinations. Leaf lengths measured 21 days post transplanting fou...
