Evaluation of Alfalfa Traits by Using Penergetic P and K under free and Infested by Dodder (Cuscuta campestris)

The goals of study were to evaluate of Alfalfa traits by using penergetic P and K under free and infested by Dodder (Cuscuta campestris).

The greenhouse experiment was conducted at the Faculty of Agriculture, University of Tabriz in 2017. The experimental design was a completely randomized design with 8 treatments and two replications. Treatments were penergetic P+dodder infested , penergetic K+dodder infested, penergetic water+dodder infested, control+dodder infested, penergetic P+dodder free, penergetic K+dodder free, penergetic water+dodder free and control+dodder free.

Different treatments of penergetic had significant effect on plant height, number of sub stem per plant, diameter of main stem, fresh weight, number of leaves per plant, chlorophyll index and alfalfa biomass. The highest plant height with 49.18cm was achieved by penergetic water + dodder free and the highest chlorophyll index under penergetic P + dodder infested. The highest biomass yield was obtained from penergetic P+ dodder free treatment and the lowest biomass yield was observed in control+dodder infested treatment.

It can be concluded that using of different treatments of penergetic in the recommended doses increase the alfalfa resistance to dodder.
