Abstract

In order to determine the rosemary (Rosmarinus officinalis L. ) dry matter and weeds under different fertilizer sources, an experiment was conducted as a split plot in a randomized complete block design with three replications at Sari Agricultural Sciences and Natural Resources University in 2016. In this experiment, the treatments include competition between plants and weeds (weedy check and weed free) as the main factor, with the sub factor being fertilizer sources, namely sheep manure, vermicompost, sheep manure + vermicompost, NPK chemical fertilizer (N 46%, P2O5 46%, and K2O 50%), NPK Nano-fertilizer, and the control (no fertilizer). Results show that competition with weeds cause rosemary shift the maximum dry matter to the upper layers of canopy (20-40 cm), while in weed free treatment, rosemary has had higher ability and uniformity in dry matter distribution in the two primary canopy layers, compared to competition with weeds. In this regard, vermicompost treatment has been successful with a mean of 49. 51 g plant-1. Studies on density and weed Biomass show that the use of vermicompost (treatment 2) reduce density and Biomass of weeds, while the chemical fertilizer causes the highest weed density and Biomass. According to the results, the use of organic fertilizers such as vermicompost, not only reduce the use of chemical fertilizers and do not have environmental consequences, but have also the high ability to suppress weeds growth and decrease weed density and Biomass.
