changes in yield and growth of green mint (mentha spicata l.) under foliar application of urea and soil application of vermicompost

a fiel experiments was laid out in agricultural research farm, city namin, ardabil province, iran in 2013. experiment was conducted in a randomized complete block with seven treatments and three replication. foliar spray treatments urea solution at a rate of 1, 2 and 3% (in two stages, the first stage a month after transplanting when they had reached 10 cm in height to 20 days after the first stage and second stage ), soil application of vermicompost fertilizer at a rate of 5, 10 and 15 tons per hectare and control. results showed that, plant height in 3% foliar urea was obtained. also, the maximum stem diameter and the lowest foliar treatment with 3% were obtained in the control. however, maximum of fresh weight per cent foliar treatments and the lowest yield was observed in the control treatment. in final results showed that, maximum leaf area was obtained by treatment with 2% urea foliar spray of 3% was shared with the group. the lowest leaf area in the control area was estimated.
