Effect of some fertilizers types and drip irrigation rates on productivity of Matricaria chamomilla L. plant under El-Arish region conditions [electronic resource].

Includes reference.

This work aimed to study the combined effect of fertilizers types (chemical fertilization, composted olive cakeJarmyard manure and their combination) and irrigation rates (467, 933 and 1400 m³/fed) on the growth, yield of both inflorescences and volatile oil and some chemical constituents of chamomile plants during the first season 2003/2004(less rainy) and second season 2004/2005 (rainy). The obtained results showed that, under the conditions of North Sinai (EI-Arish region), increasing drip irrigation rates from 467 to 1400 m³/fed. during the second (rainy) season combined with NPKfertilizers (300, 300 and 100 kg!fed. from ammonium sulphate, calcium super phosphate and potassium sulphate, respectively) plus farmyard manure resulted in 60.0% increase in inflorescences dry yield! fed. and 7/.2% in volatile oil yield more than the same treatments during the first (less rainy) season. However, increasing irrigation rate during the first season to 1400 m³ /fed gave economic yields of dry inflorescences and volatile oil. The highest irrigation rate combined with NPKb fertilizers plus farmyard manure (30m³ /fed) appeared to give the adequate balance of nitrogen, phosphorus, potassium and total carbohydrate percentages in herb. The water use efficiency was at the highest significant value during the second (rainy) season under the highest irrigation rate (1400 m3lftd) and NP K fertilizers plus farmyard manure fertilizer.
