Scheduling and organization of harvest plan in Agroforestry system with integer programming is the need of the current scenario. Existing harvest scheduling models optimize the binary decision of cutting or not cutting tree units in different time periods subjected to logistical, economic and environmental restrictions. In these models, the most common constraint is contiguous harvest size of trees which may be suitable for cutting at any threshold area in a given time period (or) periods of green up. These so-called adjacency or green-up constraints are the basic building blocks of harvest scheduling model in agroforestry. Harvest scheduling is very hard to solve without affecting nature and other restrictions; shape harvest management plan gives lenience area restrictions and adds constraints once the violation occurs during harvest to pre-specified interval of time before (or) after the current time period t. The Net Present Value (NPV) and integer programming with spatial variables are calculated. These spatial variables give clear cut decision whether the adjacent unit has been harvested in a pre-specified interval of time before (or) after the current time period t through shape harvesting model. In this model potentially feasible adjacency harvesting blocks maintain the sustainable forest environment and green-up provided the threshold area is large. This approach can also be utilized by the land lords to assess the cost crop yield which is sustainable to growing tree species in a particular time period.
