Abstract :
in order to evaluate the spraying of different concentrations of full agrotin fertilizer on quantitative and qualitative traits of rice cultivars, a split-split experiment was conducted in a randomized complete block design with four replications in Cham Divan, Visiban, 1995-2006. The tested agents consisted of different concentrations of Agrotinin fertilizer in four concentrations (control, 0.5, 1 and 1.5) and four rice cultivars (Fajr, country, Shirodi and local damsay). The results of the experiment showed that the highest plant height, number of tillers, and grain yield were recorded in local Demisahs cultivar and the highest 1000 seed weight in Shiroudi cultivar. The highest plant height, number of nodes, and grain yield were observed in agrotinin fertilizer application at a concentration of 1.5% and the highest 1000 seed weight in 1%. The highest biological yield were observed in the interaction of full agrotin fertilizer application at a concentration of 1.5 in local cultivar. In general, the results showed that the higher concentrations of agrotinane manure were effective in increasing the quantitative and qualitative yield of rice cultivars.
