Effect of foliar application of micronutrients on some morphological traits of Fenugreek (Trigonella foenum-graecum L.)

This research was aimed to investigate the effects of foliar application of micronutrients on some morphological traits in fenugreek (Trigonella foenum-graecum L.). The study was conducted in a randomized complete block design with eight treatments and three replications in 2012 at the research farm of Agriculture and Natural Resources of West Azarbaijan Research Station. Treatments included: control (no spray), foliar application of iron, zinc, manganese, iron zinc, iron manganese, zinc manganese, iron zinc manganese. These elements were provided from iron sulfate, zinc sulfate and manganese sulfate and were applied at pre-flowering stage. Results indicated that there was statistically significant difference between control and spraying of micronutrient elements. In addition, results showed that spraying of micronutrient elements significantly affected plant height, number of lateral branches, number of pods per plant, number of grain per pod and fresh forage yield. Iron zinc manganese spraying was superior compared to the other spraying treatments. Thus, results showed that the use of micronutrients could improve the morphological characteristics of Fenugreek.
