Effect of the kind of nitrogen fertilizer on the performance of host plant sunflower (Helianthurn annuas L.) in presence of parasite plant (Orobanche aegyptiaca)
Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 14
Abstract
In order to evaluate the effects of kind and amount of nitrogenous fertilizers on control of broomrape in prescience of sunflower as host plant a factorial experiment in randomized block design with 4 replication in Azad University of Saveh were down. First factor was kind of fertilizer (Urea, Ammonium nitrate, Ammonium phosphate). Second factor was dilution of nitrogen(consist of zero, 2,4 and 5 PPM) a. Results of this experiment showed that effect of kind of nitrogenous fertilizer on dry seed weight ,dry weight of broomrape and number of broomrape is significant(P=0.01).Highest dry weight of stem and leaf of sunflower were in dilution of 4 ppm of ammonium nitrate. In dilution of 5 ppm of ammonium nitrate, ammonium phosphate and urea fertilizers, highest seed of sunflower weighted. Lowest dry weight of broomrape was in dilution of 2 and 4 ppm of ammonium nitrate and least number of broomrape were counted in 5 ppm of urea form of fertilizers.
