EFFECT OF ORGANICS FERTILIZERS AND CHELATE IRON ON VEGETATIVE GROWETH OF PEPPERMINT PLANT ( Mentha piperita L.)

Abstract

Field experiment was conducted in the season of 2012 to study the effect of three levels of organic fertilizers (2.5 gm cow manure, 2.5 gm sheep manure, mixed of cow and sheep manure 2.5 and 2.5 gm) and tow levels of iron chelate ( 2.5 gm and 3.5 gm) on vegetative growth characters for peppermint plant. The results of interactions between organic fertilizers and Iron chelate showed significant differences with treatments and The treatment F2B3 gave the biggest of highest plant reached (63.00 cm / plant), highest number of branches (20.33 branch / plant ), highest number of leaves (970.00 leave / plant ), highest percent of dry matter of vegetative group (28.66%), and high leave area (97.33 cm2) along with highest chlorophyll percent (41.50 SPAD) compare with control treatment plants were gives lowest values (41.00 cm), lowest number of branches (11.00 branch / plant ), lowest number of leaves (252.00 leave / plant ), lowest percent of dry matter of vegetative group (15.83%), and lowest leave area (19.54 cm2), with lowest chlorophyll percent (26.26 SPAD),respectively.
