salinity tolerance of kentucky bluegrass as affected by nitrogen fertilization
in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...
متن کاملEvaluation of Liquid-Applied Nitrogen Fertilizers on Kentucky Bluegrass Turf
Solution and suspension N sources have been developed as substitutes Cor urea in spray solutions used by lawn-care proCessionals. A field study was conducted to evaluate the response of Kentucky bluegrass (Poa prarensis L.) growing on a Catlin silt loam (Typic ArgiudoLl), to applications oC the nell' solution and suspension N sources, alone or combined with urea, by comparison to turC response ...
متن کاملComparing nitrate storage and remobilization in two rice cultivars that differ in their nitrogen use efficiency.
Soil nitrogen (N) is available to rice crops as either nitrate or ammonium, but only nitrate can be accrued in cells and so factors that influence its storage and remobilization are important for N use efficiency (NUE). The hypothesis that the ability of rice crops to remobilize N storage pools is an indicator of NUE was tested. When two commonly grown Chinese rice cultivars, Nong Ken (NK) and ...
متن کاملStudy of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics
In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...
متن کاملResponses of rice cultivars with different nitrogen use efficiency to partial nitrate nutrition.
BACKGROUND AND AIMS There is increased evidence that partial nitrate (NO3-) nutrition (PNN) improves growth of rice (Oryza sativa), although the crop prefers ammonium (NH4+) to NO3- nutrition. It is not known whether the response to NO3- supply is related to nitrogen (N) use efficiency (NUE) in rice cultivars. Methods Solution culture experiments were carried out to study the response of two ri...
