Effects of Nitrogen and Rapeseed Residues on Grain Yield and Yield Components of Sunflower (Helianthus annuus L.) and Weed Growth
ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...
متن کاملEffect of deficit irrigation on seed yield and yield components of sunflower (Helianthus annuus L.) hybrids
This experiment was conducted to evaluate the effect of deficit irrigation on seed yield and its components of sunflower hybrids, and also identify tolerant hybrids. Twelve sunflower hybrids; Farrokh, Shams, Ghasem, Barzegar, G5 ×43, G6×43, Hysun25, Hysun36, Azargol, Sumbro, Euroflor and Sirena were evaluated under three irrigation treatments; normal irrigation (60 mm), mild drought stress (1...
متن کاملPLANT GROWTH REGULATORS INDUCED DROUGHT TOLERANCE IN SUNFLOWER (Helianthus annuus L.) HYBRIDS
Present study was conducted to investigate whether plant growth regulators viz. salicylic acid and ascorbic acid can alleviate the adverse effects of drought stress on germination and seedling growth of two sunflower hybrids (Hysun-33 and Hysun-38). Two (-0.06 MPa and -0.12 MPa) levels of drought stress were created by adding different concentrations of (PEG8000) polyethylene glycol in growth m...
متن کاملEffect of Tannery Wastewater on the Growth and Yield of Sunflower (helianthus Annuus L.)
The effects of tanneries wastewater on growth and yield of three cultivars (SF-187, CRN-1435 and DK3915) of sunflower (Helianthus annuus L.) showed that wastewater was not fit for irrigation due to extremely high mineral and heavy metal contents. In addition, effluents were highly alkaline with high load in EC, BOD, COD and SAR values. The amount of iron, manganese, zinc and chromium was also q...
متن کاملTOLERANCE OF SUNFLOWER (Helianthus annuus L.) TO IMAZETHAPYR
The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were recorded. ALS (acetolactate synthase) enzyme activ...
