BACKGROUND: Alternative furrow irrigation method is an effective procedure to reduce the amount of irrigation water in arid areas for economic production. OBJECTIVES: Assessment seed yield, its components and morphological characteristics of corn affected different level of irrigation regime and super absorbent polymer (SAP) under warm and dry climate con...
ABSTRACT- Maize production, which is ranked after wheat and barely in Fars province, Iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. Therefore, proper planting method can improve irrigation water management. The objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...
coriander is one of the important economic plants for medicinal production. this investigation consists of the effects of different drip irrigation (surface and subsurface) and furrow irrigation methods on grain, oil and essential of coriander. for this purpose, experiment over the past two years (2010 and 2011) in a randomized complete block was designed in three replications. treatments were ...

Limited water resources restrict winter wheat grain yield and quality in the Huang-Huai-Hai Plain of North China, and establishing optimal planting patterns according to crop water requirements is the key factor for achieving rational water use. In this paper, 4 planting patterns were applied, namely, uniform row (30 cm; traditional pattern), wide (40 cm)-narrow (20 cm) row, furrow (double line...
abstract this study aimed to investigate the effects of urban wastewater on some soil physical and chemical properties in segzi, east isfahan. six sites were selected considering the planted species (haloxylon persicum and nitraria schoberi) and irrigation types (control or no irrigation, water logged and furrow irrigation methods). the 4 to 12 replications were chosen in each site depending on...
A series of biopolymers added to irrigation water were tested for their efficacy in reducing shear-induced erosion in a laboratory-scale mini-furrow. Suspensions of chitosan, starch xanthate, cellulose xanthate, and acid-hydrolyzed cellulose microfibrils, at concentrations of 20, 80, 80, and 120 ppm, respectively, reduced suspended solids by more than 80%. None of these biopolymers, however, ex...
Farmers in the Indus Basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tubewells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater...
