Bio-economic Interaction of single scattered trees on farmlands
Bio-economic Interaction of single scattered trees on farmlands
Fazli Subhan Khan
ABSTRACT
Tree-crop interaction of Single Scattered Trees under
arid and semi-arid (rainfed and irrigated) areas are
discussed in bio-economics terms. The result suggests
crop suplementarity with Prospois cineraria associated
with wheat and chick peas. However, the opportunity cost
of keeping trees of Acacia nilotica and Zizyphus
mauritiana are more than the value foregone for growing
wheat and chick peas. A strong biological and financial
competition exist between trees of Acacia and Zizyphus
and agricultural crops of wheat and chick pea.
