- چکیده:
- چکیده انگلیسی: 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, 2009. The experiment was arranged as split-plot, in randomized complete block design with three replications. The irrigation regimes (irrigation after 7, 14 and 21 days interval) were arranged as main plots and combination of different N fertilizers included control, urea fertilizer (UF), broiler litter (BL), UF+BL (3:1), UF+BL (1:1), UF+BL (1:3) as subplots. Results showed that the highest shoot dry weight and N uptake were achieved with 7 and 14 days irrigation regimes, respectively. There was no significant difference between 7 and 14 days irrigation regimes for shoot dry weight and N uptake. The greatest NAE, PAE and PPE were obtained with 14 days irrigation regimes. The highest shoot dry weight, N uptake, NAE, ANR and PAE were observed with UF+BL (1:1) 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, 1:1) would help to minimize the use of synthetic mineral fertilizers and represents an environmentally and agronomically sound management strategy.

- چکیده:
- چکیده انگلیسی: Oxazole derivatives were prepared via multicomponent reaction of carbohydrazide, dialkyl acetylenedicarboxylate and ketone at room temperature under solvent-free conditions in good yields. One of the alternative materials for this reaction is carbohydrazide. In this study, in addition to introducing the properties and applications of this material as an oxidizing agent, synthesis of this compound from hydrazine has been investigated. The production process consists of two steps in which the first step involves the reaction of dimethyl carbonate with hydrazine to produced methylhydrazinocarboxylate and methanol. In the second stage, hydrazine is first added to the produced intermediate and finally carbohydrazide is produced using crystallization, filtration and drying. The results of the prepared sample analysis indicate the production of high purity carbohydrazide.
