Abstract :

In order to evaluation the effect of biofertilizers Vermi‌compost and Phosphate Barvar-2® on quantitative charactrestics and yield of green Basil (Ocimum basilicm L.) in Gachsaran region, a factorial experiment based on randomized block design with three replications was conducted in 2014. The first factor was including Phosphate Barvar-2® in four levels (0, 50, 75 and 100 g/ha) and second factor was different ratios of vermicompost and soil (0-100, 25-75, 50-50, 75–25 and100–0). Traits such as height plant, fresh and dry weight of shoots, chlorophyll index (SPAD), number of leafs and concentration of potassium and nitrogen were measured. Results showed that interaction of vermicompost and Phosphate Barvar-2® have significant effect (p<0.05) on all of traits exept chlorophyll index. The highest plant height, noumber of leaf and concentration of nitrogen and phosphorous were observed in application of Phosphate Barvar-2® at 100 g/h and equal ratio of soil and vermicompost (50-50%). The maximum sh of fresh and dry weight were obtained in plants that treted with 75 g/h Phosphate Barvar-2® and media culture 100% soil as compare to other treatments. According of obtained results, use of 75 to 100 g/h Phosphate Barvar-2® and vermicompost and soil (50-50%) is useful to improving of qualitative properties of basil in Gachsaran region.
