The concept <strong>of</strong> "Incidental Benefits" approach as discussed in Dhawan (1998) has been used to explain the phenomenon <strong>of</strong> 'canal seepage induced' groundwater potential for irrigation exploited by the farmers by the farmers in the Peechi Irrigation Project. The conventional life-cycle approach to project evaluation has been used to explain the phenomenon <strong>of</strong> cost and time oveT-Tuns and delays in completion <strong>of</strong> the irrigation projects, 3,2 Relevance <strong>of</strong> OFD The concept, On-Farm Development (OFD) is widely understood in irrigation development and water management literature as the process <strong>of</strong> land development for the smooth flow <strong>of</strong> water in the field leading to its uniform and efficient application in the crop root zone, ensuring the growth <strong>of</strong> the plant. According to the Central Water Commission (ewC), "On-Farm Development (OFD) is an integrated process <strong>of</strong> leveling and shaping the land for smooth flow <strong>of</strong> water, constructing field irrigation channels. providing drainage facilities. forming the farm roads and realigning the field boundaries through appropriate consolidation <strong>of</strong> holdings". Since land and water are the critical factors in the agricultural production process. efficiency <strong>of</strong> water use or efficiency <strong>of</strong> an irrigation system (irrespective <strong>of</strong> scale) and the resultant efficiency <strong>of</strong> crop production system is largely determined by the way in which land is developed and managed, Given this, the concept <strong>of</strong> OFD has much wider implications in the agricultural development <strong>of</strong> any region (both under rainfed and irrigated conditions) and its relevance cut across natural, physical and social sciences. Various agronomic practices involving scientific land development and water management at the farm level results in increase in crop yield and sustainability 89
<strong>of</strong> the crop production system trough agronomic measures <strong>of</strong> soil and water conservation adequately supplemented with mechanical measures such as contour bunding. bench terracing. etc. Agronomic measures help conserving water and reducing the evaporation losses from the soil surface, improving soil structure, soil fertility, etc. The choice <strong>of</strong> appropriate vegetation and cropping system depending upon the land capability necessitates adequate land development works. Land preparation and leveling including post harvest cultivation and preparatory tillage results in enhanced water intake <strong>of</strong> the soil ami sustains soil moisture status. The formation <strong>of</strong> appropriate seed bedsl ridges and furrows matching the spacing requirements <strong>of</strong> crops help control erosion and increase water use efficiency. The physiological parameters affecting plant growth necessitates replenishment <strong>of</strong> soil moisture and thereby help avoiding soil moisture loss due to evapo-transpiration (ET). The moisture availability in the crop root zone is positively related to the nutrient status. The total quantity <strong>of</strong> water required for the essential physiological functions <strong>of</strong> the plantl crop is usually less than five per cent <strong>of</strong> the total water absorbed and this entails three stages, viz., absorption, translocation and transpiration. This metabolism requires adequate and timely supply <strong>of</strong> water to the crop root zone, sufficiently conditioned by OFD works. From the engineering perspective, construction <strong>of</strong> water control structures is essential for water delivery according to the crop water requirements per unit area as well as for the timely removal <strong>of</strong> excess water from the fields. On-Farm Development (OFD) works involving surface drainage. sub-surface or pipe drainage in adequate depth and width are important to let out water to the ayacut 90
