1. EX.NO.13 VISIT TO AICRP ON AGROFORESTRY

2. Objectives: To impart knowledge about alternate land use systems . To study different ongoing experiments at AlCRP on Agroforestry . .

3. To meet the increasing food and fodder demands of burgeoning population of both human and livestock and to conserve natural resources , a diversified land use system needs to be adopted in different agro ecological regions of the country as an alternative to conventional cropping systems. Alternate Land use system (ALU'S): When land is put under an alternative production system in order to match its capability more appropriately to the new land use and achieve more sustainable biological and economic productivity on long term, it is known as alternate land use. A schematic diagram of suitable alternate land use systems based on rainfall availability and land capability suggested by Katyal et al. (1993)

4. Agroforestry : It is a collective name for land-use systems in which woody perennials (trees, shrubs, palms bamboos etc.) are grown in association with herbaceous plants (crops and pastures) or livestock, in a spatial arrangement, in rotation, or both. There are usually both ecological and economic interactions between trees and other components of the system.

5. It can be classified into agri-silviculture , alley cropping, agri-silvopastoral , agri -horticulture, silvi -pastoral and horti -pastoral etc., depending on nature of the component in the system. Tree farming, social forestry are other alternative land uses which are meant to improve the degraded natural base besides providing economic products to the community. It is aimed to optimize the use of resources through recycling., internalize the input production, reduce the risk and conservation of natural resources.

6. Practical significance: Alternate land use systems are aimed at optimizing the use of resources through the principle of recycling, internalize input production, reducing the risk and conserving the natural resources. It reduces the erosivity of rainfall and erodability of soil through dissipation of energy of rain drops by canopy at low heights, surface litter, obstructing runoff, root binding and improve sol organic matter, physico -chemical and biological properties. Students get acquainted to different alternate land use systems
