To manage the Cyperus rotundus (Purple nut sedge.) is a troublesome, economically damaging weed, widely naturalized in tropical and subtropical regions of world. A field experiment was done at Students Instructional Farm Chandra Shekhar Azad University Agriculture & Technology, Kanpur (U.P).The study conducted to investigate competitive effects C. wheat (Triticum aestivum L.) under varying ...

Irrigation is widely criticised as a profligate and wasteful user of water, especially in watershort areas. Improvements to irrigation management are proposed as a way of increasing agricultural production and reducing the demand for water. The terminology for this debate is often flawed, failing to clarify the actual disposition of water used in irrigation into evaporation, transpiration, and ...

background & aim: drought stress, as a main abiotic stress, has a significant influence on growth and metabolic activities of plant species. in this study, the influence of reduced irrigation on dry herbage, essential oil yield, and chemical components of two thyme species were investigated. experimental: this study was done in an experimental greenhouse, i.a.u., shahrekord branch, iran at...

The objective of this study was to evaluate the effect of soil moisture condition and irrigation regime on the bioelectric potential of crops with different growth stages. The bioelectric potential of broccoli (Brassica oleracea var. italica) plants at the initial and mid-growth stages was measured under different soil moisture conditions and irrigation regimes using pot experiments. The result...

in semiarid regions of iran, one of the crop production management methods is delayed irrigation after emergence. this is due to simultaneous water requirement of cereal and spring season crops. a field study was conducted in kabootarabad research station to investigate the effect of delayed irrigation on root yield, quality and growth trend using a rcb with four replications. the irrigation tr...

The estimation of heritability, genetic advance and direct effect yield attributing components on seed cotton have been used to develop indirect selection criteria. For this purpose, seven parents their F2 populations were evaluated for the identification superior be transferred further generations. Claudia x AGC-208, AGC-85 MD combinations fiber quality. highest heritability recorded in boll n...

in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...
