Effect of irrigation interval and nitrogen fertilizer rate on grain yield and yield components of rice (Oryza sativa L.) cv. Hashemi
Irrigation water deficit is an important factor that affect rice production in the world as well as Guilan province in Iran. Intermittent irrigation method can be applied to compensate for the water shortage in rice growing areas, however, it would affect other crop mangement practices such as fertilizer application and mangement. Therefore, this experiment was conducted to determine optimum fe...
متن کاملA bioeconomic model for analysis of integrated weed management strategies for annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems
This paper describes a dynamic simulation model that allows for comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Results broadly in...

Field study was conducted in order to evaluate the efficacy of new herbicide quinclorac to control barnyardgrass and bulrush, the most important weeds of paddy rice. Treatments consisted of rice cultivars (Hashemi and Khazar) and quinclorac rates (50, 100, 200 and 400% the recommended dose), recommended dose of butachlor and quinclorac, each alone and plus bensulfuronmethyl (BSM), weedy and han...
متن کاملRice Weed Control with Penoxsulam (Grasp)
Two experiments were established in 2003 at the Rice Research and Extension Center near Stuttgart, Ark., to evaluate the potential of penoxsulam (Grasp) as part of a rice weed control program. In experiment one, penoxsulam applied alone and in tank mixtures early postemergence (EPOST) (two-leaf rice, one-leaf grass, two-leaf weeds) was evaluated, and experiment two evaluated penoxsulam applied ...
متن کاملThe Feasibility Study of Utilizing Common Herbicides of Transplanted Rice for Direct Wet-Seeding of Hashemi Cultivar
To investigate some common herbicides of transplanted rice for direct wet-seeding of Hashemi cultivar, this study was conducted in a randomized complete block design with three replications. Treatments were as follow: (i) recommended dose of pretilachlor, (ii) oxadiargyl + bensulfuron-methyl, (iii-vi) adding propanil or thiobencarb to treatment (i) and (ii), (vii-x) adding cinosulfuron to treat...
