The effect of deficit irrigation and manure on quantity and quality traits of plantago ovata Forssk. in Sistan region

In order to investigate the effects of the two factors (deficit irrigation and manure) on yield and quality characteristic of the Plantago ovata Forssk. and experiment was conducted at the Research Farm, Zabol University. For this purpose split plot design based on completely randomized block with 4 replications was used. Results of the variance analysis indicated that there were significant difference between irrigation levels on the yield and it’s five dependent traits except 1000 seeds weight and Biomass. The application of manure showed significant effect for all traits except 1000 seeds weight and Plant height. Levels of irrigation and manure had no significant effects on the quality characters such as amount of mucilage and swelling factor.
