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...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

pepper plant capsicum annuum l. has great nutritional value and many pharmaceutical properties but its sensitivity to pests such as aphis gossypii glover, especially in drought stress conditions, has limited its production. to evaluate the effect of drought stress on the population and damage rate of this pest in greenhouse condition, four moisture treatments including; full irrigation, 15, 30 ...

     To evaluate the effects of hydrogel polymer levels (0, 10, 20, 30 g m-2) and NO3:NH4 ratios (0: 100, 25: 75, 50: 50, 75: 25, and 100: 0) on dill seed yield and its essential oil constituents, an experiment was conducted in October 2012 in the experimental field of Islamic Azad University, Jiroft, Iran. Results showed that using 30 g m-2 hydrogel polymer with 75NO3-: 25 NH4+ ratio produced ...

This study presents the effect of super absorbent polymer (SAP) as internal curing agent on workability, durability and compressive strength self-consolidating concrete (SCC). In order to estimate efficiency SAP in different conditions ages, electrical resistivity tests have been performed. Homogenous denser microstructure was formed by gradual release water from into pores created SAP. Further...

One of the ways overcoming cost irrigation is through in-situ water harvesting at plant roots. Super absorbent polymer (SAP) can facilitate This study attempted to assess effect SAP on available (PAW) different soils. In this study, was sequentially added rate 0.2%, 0.3% and 0.5% soil weight its impact assessed in clay, sandy clay loam The moisture retention characteristics original treated soi...
