abstract water is a main factor in production of crops. optimizing the usage of water is essential especially in iran which is a dry and semi-dry country. investigation on the effect of different irrigation treatments on chilo suppressalis walker (lep.: crambidae), as the most destructive rice pest, can be an efficient strategy in optimizing usage of water in integrated crop management (icm). i...

introduction of high yielding as well as high quality rice cultivars is one of the most important activities at rice research institute of iran (rrii). in 1991, 210 rice lines introduced from international rice research institute (irri) to rice research institute of iran were evaluated in observational and statistical experiments in mazandaran for two years, and seven lines were selected. these...

Abstract An laboratory experiment was carried out during the year 2020 at Seed Technology Laboratory of Crop Department - College Agricultural Engineering Sciences University Baghdad in order to know effect seed priming and size their embryos different cultivars maize on seedling characteristics. The a completely randomized design with four replicates. first factor included three synthetic (Al-...

in order to investigate the yield stability of eight promising rice genotypes, these lines along with shiroudi and fajr cultivars as control were sown in three regions of mazandaran province (amol, sari and tonekabon) as randomized complete block arrangements with three replications in 2012 and 2013. analysis of variance for grain yield indicated significant differences among the genotypes in a...

selection of favorite cultivars and lines affected with genotype- environment interaction dramatically. in order to study of genotype × environment interaction in rice, 12 lines with 2 commercial cultivars as check (neda and fajr) was studied in 9 different environments (3 location and 3 years). the experiment was randomized complete block design (rcbd) with three replications. the differences ...
