introduction water super absorbents are water absorbing natural or synthetic polymers (they may contain over 99% water). they have been defined as polymeric materials which exhibit the ability of swelling in water and retaining a significant fraction (> 20%) of water within their structure, without dissolving in water content. the applications of hydrogels are grown extensively. these materials...

to study the effects of two irrigation regimes and application of barley residue, zeolite and superabsorbent polymer on forage yield and some physiological traits of maize and sorghum, an experiment was conducted over two years in kerman, iran. a randomized complete block design arranged in a factorial split was used with three replications. two irrigation regimes of normal irrigation and water...

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...

abstractbackground and objectives:anise (pimpinella anisum l.) is an annual medicinal plant which belonged to the apiaaceace family. grain is the most important organ to produce essential oil of anise. in order to produce medicinal plant it is necessary to determine the environmental factors under which they give higher yields and better quality (23). in medicinal plants, balanced fertilization...

abstract in order to study the effect of super absorbent on runoff volume in slopes and various intensity of rainfall research was accomplish according to split – factorial blocks method with main treatment and two accessory treatments in three replicate . the main treatment consist of three dominant slopes (10 , 20 , 30 percent ) and accessory treatments consist of five levels of substance sup...

Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...
