Abstract

Present study was conducted to analyze the effect of Vermicompost and chemical Nitrogen fertilizer on the function and component of maize seed traits. A factorial test with complete randomize block designs was conducted at the city of Behbahan in the year 2012 with 4 repetitions. Analyzed treatments contains three level of chemical Nitrogen fertilizer viz 50, 75 and 100 percent of soil test area and application of vermicompost is also conducted at 3 levels of check (0), 5 and 10 tons in hectare. Results of the study showed a significant correlation between the quantitative traits of maize seed and various levels of chemical Nitrogen fertilizer and vermicompost. Highest functioning of maize seed was obtained from the treatment containing 100 percent Nitrogen and 10 tons/hectare of vermicompost while the lowe st amount was obtained from the treatment containing 50 percent Nitrogen without vermicompost application. Furthermore, application of vermicompost and chemical Nitrogen fertilizer affects the biological f unction and increase in the yield of seed in rows and weight of each 1000 seeds, also has positive and meaningful effect on the index of maize seed's harvesting. The results of the study revealed that the application of Nitrogen fertilizer at the levels of 50 and 75 percents of area soil test and vermicompost at the level of 5 tons in a hectare in this area are appropriate to obtain the maximum yield and proper functioning.
