abstract in order to study the sensitivity of seven crops to total herbicide soil residue, an experiment was carried out under controlled conditions in 2009 at the college of agriculture, ferdowsi university of mashhad-iran. in this study 7 crops (pea, bean, lentil, corn, rape, beet and tomato), across 7 simulated soil residual concentration of total herbicide (0, 0.0002, 0.0005, 0.001, 0.002, ...

Abstract The success of any plant development relies on healthy and vigorous seedlings, the use rhizobacteria is a sustainable alternative for production high-quality seedlings as they positively interfere in development. Thus, objective this study was to evaluate effect growth quality açaí (Euterpe oleracea Mart.), native palm Brazil, which has significant ornamental value addition ecological ...

Abstract The research was carried out in lath house of the Department Horticulture and Landscaping - College Agriculture / University Anbar during two growing season 2021-2022, order to study effect spraying with normal nano iron on growth flowering petunias. Normal used concentrations (0, 50 100 mg L -1 ), which represented by (F0, F1 F2) respectively, while sprayed 10 20 ) it (NF0, NF1 NF2) r...

Aquatic plants anchored in streams are under pressure from various constraints linked to the water flow and display strategies to prevent their damage or destruction. We assume that the responses of aquatic plants to fast-water flow are a manifestation of a trade-off consisting in either maximizing the resistance to damage (tolerance strategy) in minimizing the hydrodynamic forces (avoidance st...

Successful management and restoration of coastal vegetation requires a quantitative process-based understanding of thresholds hampering (re-)establishment of pioneer vegetation. We expected scouring to be important in explaining the disappearance of seedlings and/or small propagules of intertidal plant species, and therefore quantified the dependence of scouring on plant traits (flexibility, si...

Since the fruits would be apt to perishable and disease in open field cultivation of processing tomatoes, we attempted vertical double-shoots attracting secure a stable yield this experiment. The control plot (untreated plants) (cultivated by attracted 1st 2nd lateral shoots below top flower truss) were set. There was no difference between both plots on first flowering date. Although number flo...

abstract many uses of landscape and important roll of ground covers aspect turfgrasses caused extensive of this plant in the cities. this study focuses on shoot responses and tolerance of native and commercial turf grasses under drought stress in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

Nursery experiments were conducted to select the suitable bioinoculants with locally available organic source to improve quality seedling production of Jatropha curcas L. Two months old Clones was procured from the Mission Biofuel India Pvt. of Madurai district, Tamilnadu, India. Clones were transplanted in a mixture of UnSterilised sand, Soil, and Farm Yard Manure (FYM) in the ratio of 2:1:1 i...

to study the effect of planting date on morphological characteristic, yield and essential oil content of achillea millefolium sub sp millefolium.l., an experiment in a randomized complete blocks design (rcbd) with four treatments including four planting date (6 july, 1 august, 7 september and 7 october) in four replications was conducted. during the growing stage and at the end of experiment pe...
