摘要

Net Primary Productivity (NPP) is important parameter in determining ecosystems global warming and assessment of global carbon stocks. NPP of arid and semi-arid region is considerable for carbon cycle research and carbon storage in the Southeast Anatolia Region (SAR). In this study, samples were taken from agricultural areas during 2010-2011 growing seasons. In all a total of 2590 plant samples comprising of 750 triticale, 400 barley, 390 lentils, 600 grassland, 200 corn and 250 cotton were quantified. Average above ground NPP measured as 791.49 g m(-2) yr(-1) (wheat), 325.15 g m(-2) yr(-1) (barley), 199.24 g m(-2) yr(-1) (lentil), 155.04 g m(-2) yr(-1) (grassland), 977.79 g m(-2) year(-1) (cotton) and 2320.76 g m(-2) yr(-1) (corn). Respective values for average below ground NPP were 212.84, 89.32, 56.36, 41.08, 342.23 and 749.35 g m(-2) yr(-1). The ratio of above ground NPP/below ground NPP was different for different species. There was a high correlation between above and below ground NPP. Total NPP was measured as 31.98 Tg (10(12) g) that was 24.99 and 6.99 Tg for above and below ground NPP, respectively.
