Effect of organic and biofertilization on yield and chemical composition of caraway plant (Carum carvi, L.) [electronic resource].

Includes references.

Two field experiments were conducted at the Experimental Farm (Abis region) of the Faculty of Agriculture, Saba Basha, Alexandria University and Abou-Elmtameer Farm, Beheira, Egypt during successive season of 2010/2011 to study the effect of application of organic manure and biofertilization on yield and chemical composition of caraway oil (Carum carvi, L.). Types of both organic manure; cattle and sheep manures were allocated in the main plots. Organic manure levels (6, 9 and 12 m3/fed) were allocated in sub plots and biofertilizers treatments (Phosphorein, Microbein, Phosphorein + Microbein and uninoculation) were allocated in sub sub plots.The main results could be summerise. All fertilization treatments increased the plant height, number of main branches, fresh and dry weights of whole plant organs as well as seeds yield. The main results could be summarized as follows: the sheep manure at level 9m3/fed increased the highest mean values of all studied characters in both locations over the other ones, the microbein biofertilizers inoculation was the best treatment to obtain the highest mean values of plant height, number of main branches, fresh and dry weights of whole plant, essential oil percentage as resulted in 1.99 % in first location and the second location 1.65% and the percentage of the main components (limonene and carvon) were 43.27 % carvon and 33.49 % limonene.
