In order to investigate effect of application of Nitroxin and nitrogen chemical fertilizer on yield and yield components, split plot experiment on the basis of Randomized Complete Block Design with four replications was conducted. Four levels of Nitrogen fertilizer (N1: 100% chemical fertilizer, N2: 75% chemical fertilizer + 100% biological fertilizer, N3: 50% chemical fertilizer + 100% biologi...

the essential oil of stachys lavandulifolia vahl (lamiaceae) was isolated by hydrodistillation of the aerial parts of the plant, with a yield of 0.25%. the chemical composition of volatile oil was analyzed by capillary gc and gc/ ms. the main components were germacrene-d (13.2%), ?-phellandrene (12.7%), ?-pinene (10.2%), myrcene (9.4%), ?-pinene (8.4%) and z-?-ocimene (5.8%).
