The objective of the present study is to investigate the effects of irrigation water salinity,cow manure levels and different planting methods on ions variation in soil and their uptake bysaffron. A split-split plot arrangement was conducted in a randomized complete block designwith irrigation water salinity levels (0.45 (fresh water, S1), 1.0 (S2), 2.0 (S3) and 3.0 (S4) dS m-1)as the main plot...
The effect of 10-year continuous saffron cultivation on physical and chemical properties of a silty clay loam soil was investigated in a research farm of College of Agriculture, Shiraz University, Shiraz (52 º 33ʹ E Longitude and 29º 36ʹ N latitude), Iran. This farm was irrigated with different regimes (100% of saffron's potential evapotranspiration (ETp), 75%ETp, 50%ETp) including rain fed tre...
The objective of the present study is to investigate the effects of irrigation water salinity,cow manure levels and different planting methods on saffron quality compounds includingcrocin (coloring strength), picrocrocin (bitterness) and safranal (aromatic strength). A split-splitplot arrangement was conducted in complete randomized block design with irrigation watersalinity levels (0.45 (fresh...
Surface irrigation is the dominant method of on-farm irrigation in Egypt as well as world wide. Furrow watering is considered as one of the main types of surface irrigation. Most of the cultivated crops are grown under such type of watering. The principal advantage of furrow irrigation is the less irrigated area comparing with that under basin irrigation which equaled total cultivated acreage. ...
Water scarcity threatens food security in arid areas, highlighting the importance of water-saving agriculture for production. Agricultural management practices are developed to improve water-use efficiency, and their effects generally evaluated at field scale rather than regional scale. To figure out potential irrigation methods mulching practices, FAO AquaCrop model was first calibrated valida...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Sugarcane has been cultivated in an extensive area in Khuzestan and irrigated by hydro-flume or siphon and furrow. In a field experiment during 2005-6 at Amir Kabir Agro-Industry, Khuzestan, the effect of every other-furrow irrigation method was studied on sugarcane in regard to irrigation water volume, water use efficiency and quality and quantity of sugarcane. The experiment was conducted in ...
چکیده شیل های ارغوانی به عنوان یک عضو رسمی در قاعده سازند پابده در نقاط متعددی از زاگرس رخنمون دارند. به منظور بررسی چینه¬شناسی و محیط رسوبی شیل¬های ارغوانی در بخش شمالی حوضه زاگرس، 4 برش در استان ایلام در مناطق پاریاب، ملکشاهی، بیشه¬دراز و دره شهر به همراه برش الگوی سازند پابده واقع در تاقدیس گورپی در شرق استان خوزستان برداشت و مورد مطالعه قرار گرفت. در مجموع از این برش¬ها 507 اسلاید پالینول...
In order to investigate the effects of furrow irrigation and amount of irrigation water on yield and water use efficiency of corn, an experiment was conducted as a split plot based on a randomized complete block design with three replications for a period of two years at Agriculture Center of Mazandaran. Treatments included three levels of 100, 80 and 60 percent water requirement as the main tr...
Furrow irrigation proceeds under several soil-water-furrow hydraulics interaction dynamics. The soil erosion consequences from such interactions in furrow irrigation in Samaru had remained uncertain. A furrow irrigation-induced erosion (FIIE) model was used to simulate the potential severity of soil erosion in irrigated furrows due to interactive effects of infiltration rates, land slope, and s...
