The increasing use of medicinal plants has required mass production of these plants by using the minimum chemical inputs. In recent years, the study and evaluation of the response of medicinal plants to the use of organic and biological fertilizers has a special place in the research. Pumpkin skin (Cucurbita pepo Var.striaca) is one of the most important medicinal plants that, due to its high quality oil, has a therapeutic aspect in addition to oral intake, Therefore, this research was carried out with the aim of evaluating quantitative and qualitative performance of pumpkin skin under biofertilizer treatments.
Materials and Methods:
This experiment was conducted as a randomized complete block design in a research farm of Gorgan University of Agricultural Sciences and Natural Resources in four replications In 2017, it was done. Treatments included: fulvic acid (2, 4 milliliters), compost tea (2 levels 20, 10 ml), lignin (at 2 levels 0.2, 0.4 g) and control treatment (no fertilizer application). In this experiment, traits such as total phenol, total flavonoid, total antioxidant, oil percentage, free fatty acid, linoleic acid, oleic acid, protein, 1000 seed weight, grain yield and biological yield were measured in pumpkin squash. Analysis of variance of data was done using SAS software. Mean comparison of data was done by LSD test.
The results of analysis of variance showed that the effect of experimental treatments on phenol total, total flavonoid, total antioxidant, oil percentage, free fatty acid, linoleic acid, oleic acid, protein and quantitative traits of gingiva was significant at 1% probability level. . Based on the results of this experiment, the control treatments and the application of lignin have a higher total of phenol and flavonoid than compost tea and fulvic acid, which has antioxidants, phenols and flavonoids. Also, unlike phenol and flavonoid, the highest amount was obtained for oil percent, oleic acid and linoleic acid in foil and tea compost treatments. The percentage of oil in control treatments (35.1%), lignin 0.4 g (36.8%), lignin 0.2 g (37.9%), tea compost 10 ml (36.3%), treatment Folivic acid was 2 ml (39.7%), 4 ml folic acid (44.6%) and tea compost 20 ml (42.7%). According to the results of this study, the highest amount of grain yield was observed in Folivic acid and Compost tea treatments, which was significantly higher in lignin and control treatments. Grain yield was observed in treatments in 2 mL Folivic acid treatments, 4 mL Folivic acid, 10 milliliters of compost tea, 20 milliliters of compost tea, 0.2 gram of lignin, 0.4 grams of lignin and The control was 1144, 1044, 909, 997/7, 820.0, 862.7 and 780.7 kg / ha, respectively.
In general, the results of this experiment showed that for the quantitative and qualitative improvement of pumpkin seeds, as much as possible, folic acid 4 milliliters and 20 milliliters of compost tea should be used, in addition to increasing the grain and oil yield Pumpkin seeds make the soil more desirable.
