Effect of Planting Time and Density on Yield and Quality of Peppermint (mentha Piperita L.) under Su-tropical Condition

چکیده
A field trial was conducted at the research farm of RRL, Jorhat during 1995 and 1996 to study the performance of Mentha Piperita under varying dates of planting and row spacings, maximum herbage and oil yield were obtained from January plants crops. Yield deceased when planting was delayed planting at a closer row spacing of 45 cm recorded the maximum herbage yield of 61'92 q/a while the yield was reduced with wider row spacing of 360 cm or 75cm. However, the quality of oil as measured by the menthol content (71'0 - 72'3% was not affected by planting time as well as spacings.
