چکیده مقاله:
In order to evaluate the response of major nutrients concentration, uptake and their efficiencies of isabgol (Plantago ovata) to N fertilizer combinations and irrigation regimes, a field experiment was conducted at the agricultural research farm of Shahrekord University, ۲۰۰۹. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation regimes (irrigation after ۷, ۱۴ and ۲۱ days interval) were arranged as main plots and combination of different N fertilizers included control, urea fertilizer (UF), broiler litter (BL), UF+BL (۳:۱), UF+BL (۱:۱), UF+BL (۱:۳) as subplots. Results showed that the highest shoot dry weight and N uptake were achieved with ۷ and ۱۴ days irrigation regimes, respectively. There was no significant difference between ۷ and ۱۴ days irrigation regimes for shoot dry weight and N uptake. The greatest NAE, PAE and PPE were obtained with ۱۴ days irrigation regimes. The highest shoot dry weight, N uptake, NAE, ANR and PAE were observed with UF+BL (۱:۱) as well as. UF+BL treatment led to increase NAE, ANR, PAE greater than solitary application of them. In conclusion, increase in N and P efficiency and dry matter associated with combined treatment (UF+Bl, ۱:۱) would help to minimize the use of synthetic mineral fertilizers and represents an environmentally and agronomically sound management strategy.
