Effect of different treatments of nitrogen and distance of planting rows on content of mosilage and yield in Plantago Ovata Forsk

The Plantago ovata forsk. is one of the most precious medicinal plants. evaluation of factors which could affects on growth، development، yield and mosilage of seed are important Furthermore، distance of planting rows is one of the basic factors that could affect on yield and component. There fore، in this research work the effect of different treatments of nitrogen (0،50.، 100 and 150Kg/ha) and row distance (15،20 and 25cm) with 4 replicates were evaluated in a factorial experiment in a randomized complete block design under conditions of experimental farm of jiroft azad university. Analyzed data revealed significant effects of nitrogen fertilizer on yield، weight of 1000 grains، and mosilage percentage، plant height in 5%statistical level. The effect of distance of row on plan height was significant in 5% statistical level. The interaction between distance of row and nitrogen on weight of 1000grains was significant in 1%statistical level. The compare of mean of interaction between nitrogen and row distance by Duncan test showed the highest weight of 1000grains 2. 8g by treatment (50Kg nitrogen and 15cm distance between rows). The highest mosilage percent age obtained By treatment 50Kg nitrogen and 20cm distance between rows.
