In order to reducing the risk of heavy metals concentration in plant tissues which are among the edible plants by human, find the active carbon ability in heavy metals removal from Lead (Pb) and Cadmium (Cd) contaminated soils and its effect on growth and nutrient absorption of Sweet basil, this greenhouse experiment was conducted in the faculty of agriculture, Islamic Azad University, Karaj br...
abstract to find out how maize and potato can grow and develop in an intercropping system rather than each grown alone in a sole cropping system the following factorial experiment was performend in the frame-work of a randomized complete block three replications in the experimental farm of the faculty of agriculture, zanjan university in year 2004. different potato to maize ratios of (1:0), i.e...
in order to evaluation the effect of mixed cropping on yield and agronomical characteristics of wheat (triticum aestivum l.) varieties, a field experiment based on a randomized complete block design with four replications was carried out at city of mahvelat in khorasan razavi province, iran, during growing season of 2007-2008. treatments including five sole cultures of conventional wheat cultiv...
Intercropped corn (Zeu mays L.) and soybean [Glycine mux (L.) Merr.] may produce more total yield per hectare than either grown separately, ie., land equivalent ratio (LER) >l. Low N fertility, limited moisture, and weed competition have each been reported to result in high land equivalent ratios. Thus it was hypothesized that intercropping advantages were greater under stress conditions. The o...
Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...
Conservatiion with respect to physiological aspects of crops is a crucial factor for ideal photosynthesis and appropriate yield in arid and semi-arid agro-ecosystems. In order to investigate the effect of planting pattern on stability of physiological parameters of fenugreek and black cumin under drought stress, an experiment was conducted in the University of Shahrekord in 2014. Three drought ...
A study was carried out to determine the composition and predominance of weed species in wheat field in Khokana of Kathmandu valley as a representative sample of mountain ecosystem in Nepal. A total of 44 weed species representing 18 families were recorded. The most abundant species were Chenopodium album, Polygonum plebeium and Spergula arvensis. With the improved temperature after February, t...
Enhanced degradation of atrazine has been reported in the literature, indicating the potential for reduced residual weed control with this herbicide. Experiments were conducted to determine the field dissipation of atrazine in three cropping systems: continuous Zea mays L. (CC) receiving atrazine applications each year, Gossypium hirsutum L.-Z. mays rotation (CCR) receiving applications of atra...
The Farm Scale Evaluations (FSEs) showed that genetically modified herbicide-tolerant (GMHT) cropping systems could influence farmland biodiversity because of their effects on weed biomass and seed production. Recently published results for winter oilseed rape showed that a switch to GMHT crops significantly affected weed seedbanks for at least 2 years after the crops were sown, potentially cau...
