Title: Total costs, labor requirements and work efficiencies in second fodder corn silage production: A case study from Samsun Province in Turkey*
Abstract: This study was carried out to determine the total costs, labor requirements, and work efficiencies in the second fodder corn silage production mechanization using survey and time measurement method in Çarşamba town of Samsun district in 2018.The total variable and fixed costs are calculated as 3047.70TL ha -1 and 7986.60 TL ha -1 , respectively.The share of variable and fixed costs in total production costs was determined as 27.59 and 72.41%, respectively.Among the variable costs, the highest share was obtained by fertilization (9.54%) and spraying processes (4.18%).The highest share of the fixed costs was family labor (24.53%).The highest and the lowest labor requirements were found for harvesting (4.98 h ha -1 ) and transportation (1.76 h ha -1 ), respectively.The highest work efficiency was obtained for transportation (0.57 ha h -1 ).It has been shown, in particular, that good mechanization planning can minimize variable costs, resulting in more profitable production through the optimal utilization of agricultural machinery.
