Effects of different nutrition systems on quantity characteristics of fennel (Foeniculum valgare Mill) under different irrigation regimes

In order to study the effects of different nutrition systems (Organic and Chemical) on quantity characteristics of Fennel (Foeniculum vulgare Mill) under water deficit stress، an experiment was conducted in a split plot arrangement in randomizes complete block desing with three replication at the field station of Tarbiat Modares University in Peykan shahr during 2009 cropping season. In this study، the main plots were three irrigation regime levels (Soil water contact 40 %(favorite irrigate)، Soil water contact 60 % (moderate stress) and Soil water contact 80 % (sever stress) and Sub-plots were different nutrition systems (without organic manure، 100% manure cattle، 100% spent mushroom compost and 50% cattle manure with 50% spent mushroom compost and 100% N). Results showed that different nutrition systems and drought stress significantly affected all of measured traits. Also Interaction of drought stress ´ nutrition systems was significant. The highest yield and the least grain yield was Interaction of consumption Soil water contact 40 Chemical systems and Interaction of sever stress without Nutriation، respectively.
