In order to investigate the effects of compost and nitrogen on quantitative and protein content of forage corn and some physical and chemical properties of soil, a factorial experiment with 9 treatments in a factorial randomized complete block design has been conducted in the farm of Tehran Agricultural and Natural Resources Research and Education Center during 2014. The treatments include three levels of residual compost (0, 10, and 20 Ton.ha-1) and three levels of nitrogen (0, 100, and 200 kg.ha-1) as urea. The effect of municipal waste and nitrogen compost on yield and yield components has been significant. The use of municipal solid waste compost has significantly increased the electrical conductivity of soil, nitrate, iron, and zinc uptake, while significantly decreasing soil reaction. Waste compost application has also improved some soil physical properties. Bulk density is significantly reduced and field capacity and soil available water are increased. Therefore, in the similar soil conditions of this ersearch, the use of 200 kg.ha-1 of pure nitrogen from the urea source with 20 Ton.ha-1 of municipal solid waste compost is recommended to achieve the maximum dry forage yield of 21.44 tons per hectare.

In order to study the effect of bio-fertilizers and putrescine on biomass, nodulation, and some morphological and biochemical traits of vetch(vicia villosa)under rainfed conditions, a factorial experiment has been conducted based on randomized complete block design with three replications in research farm of University of Mohaghegh Ardabili within 2018-2019. The studied factors include bio-fertilizers(withoutbio-fertilizersas control, application of Rhizobium (Rhizobium legominuzarum), Mycorrhiza (Glomus mosseae), both application of Mycorrhiza and Rhizobium, Rhizobium and Azotobacter (Azotobacter chrocoocom strain 5), Mycorrhiza and Azotobacter, Rhizobium with Mycorrhiza,and Azotobacter) as well as foliar application of putrescine in three levels (foliar application with water as the control, application of 0.5 and 1 mM putrescine). Results show that both application of Azotobacter with Mycorrhiza and Rhizobium and foliar application of 1 mM putrescine increase root weight, leaf share from total biomass, soluble sugars of leaf and stem, and total biomass by 133.33%, 4.5%, 31.94%, 41.82%, and 56.94%, respectively, in comparison with no application of bio-fertilizers and putrescine. Also, application of Azotobacter with Mycorrhiza and Rhizobium and foliar application of 1 mM putrescine decrease electrical conductivity and malondialdehyde by 99% and 125.39%, respectively, in comparison with no application of bio-fertilizers and putrescine. It seems that application of bio-fertilizers and foliar application of putrescine can boost total biomass of vica villosa under rainfed condition as it improves both biochemical and morphological traits.
