Abstract

Background and objective: In order to investigate the impacts of winter cover crops and their removal methods on qualitative yield and income of greenhouse tobacco type (K326), an experiment was conducted as a split plot based on randomized complete block design with four replications in Tobbaco Research Center of Tirtash in 2012-2013. The main factor was cover crop (inclusing WHEAT, WM; BERSEEM CLOVER, BC; hairy vetch, HV; and bitter vetch, CP) and sub-plots included removal treatments (Paraquat+ mulch, PM; Glyphosate+ Mulch, GM; Moving+ Mulch, MM) and control (without cover crop control and MULCH MANAGEMENT).Materials ad methods: In December 2011, the cover crops were sown with 50, 50, 25 and 200 Kg ha-1 seed rate for bitter vetch, hairy vetch, BERSEEM CLOVER and WHEAT, respectively. On April 24, 2011 cover crops removed by with herbicide and stem cutting and they remained on the land surface as mulch. On late February 2014, tobacco was sown in seedbed and on May 8, 2012, the seedlings with 15-20 cm height were transplanted into the field. Forty days after transplanting, the first leaves harvesting was conducted and their sugar, nicotine, phosphor, nitrogen, potassium, chlorine contents and leaf yield were measured.Results: Cover crops and MULCH MANAGEMENT had no significant effect on the nicotine and total leaf nitrogen content. Interacted effect of both factors was significant on the sugar content, as the maximum (15.95%) and minimum (11.27%( levels were related to WM-MM and HV-PM, respectively. The interaction effect of MULCH MANAGEMENT and cover crop on potassium content was significant. The maximum and minimum potassium levels were related to WM (2.53%) and HV (2.15%), respectively. Cover crop effect on phosphorus content was significant and the highest content related to BC (1.29%) and the lowest (0.8%) related to WM. Combined treatment of MULCH MANAGEMENT × cover crop had significant effect on the tobacco fee.Conclusion: Overall results revealed that cover crops along with MULCH MANAGEMENT could be considered as an appropriate alternative to improve qualitative characteristics of tobacco along with increasing the fee and farmer’s income. Also could be a proper alternative for chemical inputs to move toward sustainable agriculture goals.
