Katoul is a new soybeam cultivar originated from a genotype named D.P.X.3589 imported from the United States of American in 1990. This genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in Gorgan and other research stations during 1999-2002. The mean seed yield of D.P.X.3589 in all these experiments was 3333 kgha-1 ...

Wastewaters from leather processing are very complex and lead to water pollution if discharged untreated, especially due to its high organic loading. In this study the survival of different plant species in subsurface horizontal flow constructed wetlands receiving tannery wastewater was investigated. Five pilot units were vegetated with Canna indica, Typha latifolia, Phragmites australis, Steno...

The use of organic and biological fertilizers is important for achieving sustainable agriculture, reducing the application of chemical fertilizers and the production of healthy crops. A greenhouse experiment was carried out to study the effects of vermicompost, Nitragin, and nitrogen on some growth parameters of strawberry (Fragariaananassa Duch. cv. Aromas). Treatments were arranged in a facto...
