Studies on the productivity of peppermint (mentha piperita l.)‎ Under different locations in upper Egypt conditions

Abstract EN

The productivity of Menthe pipe Rita of fresh, dry herb and its volatile oil were determined in four locations in upper Egypt (Beni-Suef, Sohag, Qena and Aswan Governorates).The productivity of fresh herb at Beni-Suef was the highest (7.36 kg/ m) followed by Sohag, Qena and Aswan (6.00, 5.72, 5.19 kg / m2, respectively), this was equal to 30.91, 25.17, 24.03 and 21.80 ton / fed.

(4200 m2) for the four locations, respectively.

The dry herb weight was 0.70, 0.56, 0.54 and 0.49 kg / m2 equal to 2.92, 2.33, 2.25 and 2.06 ton/fed.

The oil percentage in the dry herb was that determined to show the highest value (2.72 %) in Aswan and the least in Beni-Suef (1.71 %) and where the some values in Sohag and Qena were 2.55 & 2.51%.

The highest content of Menthol was obtained from Qena and Aswan (51.09 and 51.32 %) and the least from Beni-Suef (44.45 %).

On the other side, the highest content of Mentone was obtained from Beni-Suef (32.87 %) and the least from Qena (24.7 %) while Sohag and Aswan came in between (30.25 and 29.84 %).

Iso-Menthon and pulegon contents were less in Beni-Suef than other locations (3.01 %).
