Effect of seaweed extract and vermicompost on yield and yield components and phosphor and chlorophyll of Mung bean in Varamin region

An experimental trial was conducted In order to evaluate the effect of extracts of seaweed and vermicompost fertilizer on mung bean in the summer 2014 in Varamin. A split plot factorial in a randomized complete block design with three replications was used. Treatments included seaweed extract under the brand Liquid Steamplex, vermicompost fertilizer and mung bean Partoo and a promising line vc6173B. The first factor with 3 levels, without the use of seaweed extract, seaweed extract sprayed 2 times and 4 times during the growing season with a concentration of 2 per thousand, the second factor with 2 levels of no use and the use of vermicompost (10 tons per hectare) and mung bean Partoo variety and a promising line vc6173B was used as the third factor. Simple effects results showed that maximum grain yield obtained with 2 time seaweed spraying, using vermicompost and the Partoo variety with 1553, 1600 and 1573.3 kg h-1 respectively.Highest foliar biomass was produced by 4 times seaweed spraying, using vermicompost treatment and Partoo variety with 6240, 5880 and 5880 kg h-1 respectively. Among the threeway interactions the highest grain yield and biological yield was produced by using four times seaweed spraying with the use of vermicompost in Partoo variety with 1720 and 6960 kg h-1 respectively. According to the results, seaweed extract spraying increased the vegetative growth and the use of vermicompost by creating a favorable conditions, provided a better plant growth. Also Partoo variety had a higher yield.
