“…Effect of salinity on percent of filled panicles has also been reported by other researchers (Clermont-Dauphina et al, 2010). In fact these traits are the most important factors to reach the maximum yield of rice (Casanova et al, 2000). Therefore any kind of reduction in these traits highly affects the yield.…”

“…Reports indicated that salinity stress caused reduction in leaf water potential, evapotranspiration, stomatal conductance, leaf area and yield of plants (Asch et al, 2000;Casanova et al, 2000;Zeng and Shannon, 2000;Zeng et al, 2003;Castillo et al, 2007). Although some investigations were devoted on salinity effects on rice, the number of studies performed in Iran is still few.…”

Guilan, a well-known province in rice production in Iran, has been facing water shortage and water degradation. In order to study the effects of salinity stress as well as water stress on rice a pot experiment was conducted at Rice Research Institute of Iran. Five water salinity levels: fresh water (EC = 1 dS m -1 ), 2, 4, 6 and 8 dS m -1 and five irrigation regimes: continues flooding, Alternative Wetting and Drying (AWD), intermittent irrigation at 100, 90 and 80 percent of field capacity (FC) were considered as irrigation treatments. The results showed severe effects of water and salinity stresses on rice yield and yield components. Fresh water produced the highest yield, 18.57 gr pot -1 , whereas, the yield in salinity levels of 2, 4, 6 and 8 dS m -1 were 13.78, 5.78, 3.61 and 0.74 gr pot -1 , respectively, with the yield losses of 25, 70, 80 and 97%, respectively. Intermittent irrigation at FC produced the highest yield. The yield increased 8 and 13% in AWD and intermittent irrigation at FC treatments respectively, while it decreased 8 and 27% in intermittent irrigation at 80 and 90% of FC treatments as compared with continues flooding treatment. The highest yield with application of intermittent irrigation at FC was valid only in water salinity less than 4 dS m -1 . When water salinity was higher than 4 dS m -1 all irrigation methods gave the same yield. This study showed that the best method to use saline water was intermittent irrigation at FC with EC = 2 dS m -1 . In case of more salinity, mixing fresh and saline water and intermittent irrigation can mitigate the severe effects of salinity on rice. . Če je bila slanost vode večja, so dali vsi postopki namakanja enak pridelek. Raziskava je pokazala, da je najboljši način periodičnega namakanja s slano vodo pri poljski kapacite s prevodnostjo vode za namakanje 2 dS m -1 . V primeru večje slanosti je potrebno izmenično namakati s sladko in slano vodo, da se izognemu velikemu učinku slanosti na pridelek riža.Ključne besede: riž, namakanje, slana voda, Iran M.

“…Factors, such as variety and the cultivation environment, were then examined for their effect on these individual components and the eventual yield (Agata, 1993). Rational approaches focusing on yield components and cultivars that are specifically oriented to improve yield contribute to the current high-yield techniques (Casanova et al, 2002;Seker and Serin, 2004).…”

“…Becker and Johnson (1999) have concluded from observations at 64 sites in Coˆte d'Ivore that water management was the most influential factor that explained variation in grain yield between fields. Casanova et al (1999Casanova et al ( , 2002 have investigated soils, rice plants, and grain yields from over 30 direct-seeded paddy fields (0.5-3.0 ha) in eastern Spain. They related grain yield to topsoil CEC, which correlated with clay content, and to soil salinity, which was attributed to quality of ground water at various geographical location of each field near the ocean.…”

Variability of Micro-elevation, Yield, and Protein Content within a Transplanted Paddy Field

Due to the nature of waterlogged fields used for rice production, we hypothesized that microelevation (micro-relief, micro-topography, or differences in elevation) is an important factor for sitespecific management within rice fields. A 0.5-ha transplanted and weed-free paddy field was selected as the observation site, where there was micro-elevation in a range of 100 mm within the field. Combine-monitored grain yield and the surveyed micro-elevation were compared at 96 locations in the field, and 60 hand-taken grain samples were analysed for protein content. Grain yield and protein content showed significant negative correlations with micro-elevation (r ¼ )0.50 *** and )0.67 *** , respectively), indicating that at lower elevations, grain yield increased gradually with protein content. Spatial variation in yield and protein content was attributed to availability of water and nutrient uptake at locations with different micro-elevation. Therefore, micro-elevation is expected to be one of the important factors for managing spatial variation in a small paddy field.
