Sažetak	Agrifood value chain analysis traces a food product through the full sequence of value-adding activities — from input supply and farming through processing, trade, and retail to the final consumer — and asks how value, costs, and power are distributed along that chain and where smallholders and processors can capture more. The method follows Kaplinsky and Morris's influential Handbook for Value Chain Research, which provides the practical apparatus for mapping a chain, quantifying flows and margins, and analysing governance and upgrading. Gereffi, Humphrey, and Sturgeon's theory of global value chain governance supplies the lens for understanding who coordinates the chain and how that coordination shapes the prospects for upgrading.	Gross margin analysis is the workhorse of farm management planning: for each enterprise on a farm it computes the gross margin — gross output minus the variable costs directly attributable to that enterprise — usually expressed per hectare, per head, or per activity unit. Rooted in the British farm-planning tradition of Barnard and Nix and a fixture of standard farm management texts, the gross margin deliberately stops short of fixed and overhead costs. That makes it the natural currency for comparing enterprises and planning the farm: because fixed costs are largely common to all enterprises in the short run, ranking and combining enterprises by their gross margins per unit of the scarce resource is the quickest route to a more profitable farm plan.
