iran is mainly situated in a dry climate part of the world. due to the limiting and scarce water resources, crop production in the country is increasingly facing water shortages. a field experiment was conducted to investigate the impact of irrigation regimes on growth, chlorophyll fluorescence and grain yield of maize in 2006 at the research farm, college of agriculture, isfahan university of ...

The effect of different irrigation quantities on the growth, marketable yield, crop quality (antioxidant activity, mineral and total phenolic content) and irrigation water use efficiency (IWUE) of spinach grown in a semi-arid region of high altitude (1795 m a.s.l.) was determined. Plants were irrigated with three different irrigation quantities which determined considering 100 (I1), 85 (I2) and...

in order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of goldasht spring safflower cultivars (carthamus tinctorius l.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the agricultural research station of islamic azad university of roudehen branc...

                In order to determine the best developmental stage of three common bean cultivars (Talash, COS16 and Khomain) at which maximum seed quality is attained under different irrigation regimes (I1-irrigation after 60 mm, I2-irrigation after 80 mm and I3-irrigation after 100 mm evaporation from class A pan), a split plot experiment (using R.C.B. design) with 3 replications was conducte...

Moisture is a significant component in cotton growth and yield, but stress the main factor limiting crop productivity since it has negative impact on cotton's ability to produce high-quality fiber as well square/boll lint output. Reduced water availability during development of bolls could lead drastically decreased yield. Four genotypes (MNH-1020, FH-114, BH-178 CIM-602) were grown under regul...

Plastic mulched ridge-furrow irrigation is a useful method to improve crop productivity and decrease salt accumulation in arid saline areas. However, inappropriate fertilizer practices may result ecological environmental problems. In order the resource use efficiency these areas, we investigated effects of different amounts (400 (I1), 300 (I2) 200 (I3) mm) nitrogen application rates (300 (F1) 1...

A field experiment was performed in order to evaluate the effects of irrigation and application of K fertilizer on seed storage proteins  in chickpea, ILC-482 cultivar. Experiment was performed in factorial using randomized complete block design with three replications. In this experiment, two factor consist of irrigation in three levels (I1= non irrigation and I2= irrigation in flowering stage...

Studies on insect dispersal and other behaviors can benefit from using markers that will not alter flight and fitness. Rare earth elements, such as samarium (Sm), have been used as ingested markers of some insects and detected using neutron activation analysis (NAA). In this study, samarium nitrate hexahydrate was mixed into artificial diet for boll weevils, Anthonomus grandis grandis Boheman (...
