37. RESEARCH PRIORTATION FOR WATERSHED DEVELOPMENT 1.3Land Resource Inventory and GIS Database for Watershed Planning Study of natural resources, evaluating soil resources for prioritization of soil and water conservation and assessing suitability of crops. Identification of various constraints affecting crops productivity and planning for addressing constraints to enhance the productivity of crops.

39. Research priorities in terms of Horticulture component • Perennial Horticultural components such as fruit crops (Mango, Sapota, Tamarind, Custard apple, amla etc) vegetable crops (curry leaf, drumstick) and perennial species may be introduced for utilizing soil moisture from deeper soil horizons apart from conserving soil and rain water • Mixed dryland orchard systems such as mango/sapota + lime/papaya/custard apple has ample scope in getting early returns with minimum expenditure towards inputs specially labour • Short duration and intensive horticultural activities such as nurseries, cultivation of short duration vegetables such as green leafy and leguminous vegetables can be adopted under watershed areas through which soil physical and chemical properties will be improved. • Drought hardy annual (e.g. Gailardia) and perennial (e.g.Jasmine, chrysanthemum) flower crops and medicinal and aromatic can also be adopted.
