    ABSTRACT: Cattle manure is a potential for causing detrimental effects on human health due to its high solid matter and pathogen microorganism content. This study aims to achieve biogas production by stabilizing the waste using anaerobic digestion. Digested waste was utilized as natural fertilizer. For that reason, a pilot-scale anaerobic digestion tank was operated and digested wastes were added to soil in diverse dosages where alfalfa, the mixture of Hungarian vetch and barley and corn silage are planted. Corn silage was fed to the reactor as a supplementary material during anaerobic digestion process. Installation and operating costs are determined for 1,000 cattle by the results obtained and the literature datas. Installation cost was evaluated considering both installed electricity producted system and non-installed electricity producted system. As a result, according to best results, the system would pay for itself in 2. 5 years when electricity production system is installed while the system is not installed, the payoff would be realized in 2. 1 years for the mixture of Hungarian vetch and barley.

    ABSTRACT: This study was carried out to determinate the yield and yield characteristics of some grasspea lines under Tokat-Kazova ecological conditions in 2007/08 and 2008/09 years. Five grasspea lines were obtained from ICARDA. One grasspea cultivar was obtained from Central Research Institute of Field Crops, and one local population was obtained from Elazig. The research was designed according to a randomized block design with four replicates. In this research, grasspea lines will be hand-planted in a plot that is 5 m long and 3.0 m width containing 12 rows and 25 cm between the rows. Plants vegetative characteristics will be determined at 50% flowering and generative characteristics will be determined at harvest. According to average two years, green forage yields ranged from 2175.2 to 2582.5 kg/da, dry matter yields varied from 600.7 to 743.3 kg/da, seed yields from 173.3 to 202.8 kg/da, biological yields from 565.8 to 693.7 kg/da, 1000 seed weights from 93.7 to 141.3 g and harvest index from 27.66 to 31.70 %.
