Effect of water stress and potassium fertilizer on the growth, yield and composition of essential oil of fennel plant [electronic resource]. تأثير الاجهاد المائي والتسميد البوتاسي علي النمو والمحصول والمكونات الكيميائية للزيت العطري لنبات الشمر. p.931-946. Includes references. Two field experiments were carried out at Sakha Agricultural Research Station during the 2009 and 2010 seasons to investigate the impact of water stress treatments (40, 60 and 80% depletion from available soil water) and potassium fertilizer levels (18, 24 and 30kg K,O/fed) as potassiuin sulphate on the growth, yield and essential oil of fennel plants. The obtained results showed that supplying plants with a water level of 40% from available soil water and 30kg f<20/fed were effective on raising the productlvity of fruit yield and essential oil. The interaction between these two treatments gave the best results. Concerning essential oil constituents, methyl cnavicol (estragole) was the major compound, followed by limonene, fenchone, anethole, a pinene, myrcene and 13 pinene. The values of consumptive use, water applied and water storage in the effective root zone Vlere clearly affected by irrigation treatments where the highest values for the three studied parameters were increased under 11 (irrigation at depletion of 40% from available water, consequently, the values of these parameters can be arranged descendingly as follows: l1> l2> l3 while, the mean values of water application efficiency can be arranged descendingly in order of l3>l2>l1.
