Abstract : The effect of phosphate bio-fertilizer on occurrence of the dominant weeds in wheat field was investigated in a 5×3 factorial
experiment in a randomized complete block design with 3 replications. The first factor, fertilizer, comprised of five levels,
super phosphate triples 0, 100 and 200 kgha-1 as chemical fertilizer and Barvar 2 and 3 100 gha-1 as bio-fertilizer, and the
second factor, cultivar, comprised of Shiraz, Marvdasht and Bahar. Results indicated that the bio-fertilizer application
reduced Hordeummurinum, Cardariadraba, Stellaria media, Alopecurusmyosuroides, and Lamiumamplexicaule occurrence,
but increased Cirsiumarvensis and Lactucaserriola. In addition, Bahar cultivar had better competition with weeds compared
to the other cultivars. Therefore, bio-fertilizer application and Bahar cultivar are recommended for the similar regions.
Results of field study were supported by greenhouse researches. The greenhouse trials demonstrated that weed’s height, seed
fecundity and seed rain in biological fertilizer treatments had significant difference with control and chemical fertilizer treatments.
Keywords- Bio-fertilizer, weed, nutrient uptake, competition, weed management.
