Abstract:
In order to evaluate the effect of vermicompost and vermiwash biofertilizers on the traits of fenugreek (Trigonella foenum) plant, a field experiment of a randomized complete block design with 8 treatments and 3 replications was conducted. The treatments consisted of control without fertilizer, vermicompost at 5, 10, and 15 tons per hectare, vermiwash spraying with 3,000, 6,000, and 12,000 ppm, and a combined application of 10 tons of vermicompost with 6,000 ppm vermiwash. In this research, traits of crop growth rate (CGR), pod length, pod width, grain yield, chlorophyll a and b, essential oil percentage, and essential oil yield were evaluated. The results revealed that the use of vermicompost biofertilizer increased the measured quantitative traits more than that of the vermiwash. The most and the least effects on all traits, except for the length of the pod, were 15 and 5 tons vermicompost per hectare, respectively. The treatment of 10 tons of vermicompost with 6,000 ppm vermiwash did not show significant differences in 10 and 15 tons vermicompost per hectare in most traits. It was observed that the application of vermicompost fertilizer leads to weaker results than the vermiwash fertilizer. With the increase of vermiwash concentration, the effect of this fertilizer on the measured traits reduced; however, in most traits, the results of the application of 3,000 and 6,000 ppm vermiwash had a statistically significant effect on the treatment with 5 tons of vermicompost per hectare. Overall, this experiment showed that all the evaluated traits in this study have a positive reaction to the application of vermicompost and vermiwash biofertilizers. Also, the response of the fenugreek plant to the vermicompost is much greater than the vermiwash fertilizer.
