Support to the National Water Mission NAPCC Appendix 3 Kshipra Sub Basin rainfall is 939mm in Indore, 1083mm in Dewas and 916mm in Ujjain (CGWB 2009), 91% of this rainfall occurs during the four monsoon month from June to September only. The water requirement for most of the Rabi and Kharif crops in the region is 300mm to 500mm. From this, it would appear that conjunctive use of rainfall and recharge to groundwater would be able to sustain two crops from the average annual rainfall. Average water requirement for the major crop grown in Chambal basin is shown in Table 32. Table 32: Crop Water Needs Crop Kharif Crop (mm) Water Requirement Watering regime Ground nut 400 to 450 (Paleo watering required) Urd, Moong, Arher 300 (One or Two watering) Mustard 400 to 450 Oil seeds Rabi 150 to 200 Wheat 380 to 400 (3 irrigation watering) Gram 300 (One or Two watering) Potato 500 to 600 (frequent watering) D. Agriculture Options to Reduce Water Demand 112. Major constrains for agriculture activities include: hot summer months, low humidity, high evapotranspiration and meagre rainfall during winters and summer months. Irrigation watering is provided mostly through tubewells. Stage of groundwater development is 104% in Indore, 64% in Dewas and 109% in Ujjain. Decline of groundwater table is becoming a problem in the area. Shortage of drinking water is reported in many areas in the basin. The key requirements for water management in the sub- basin to meet these needs includes: (i) conservation of water; (ii) recharge of groundwater and (iii) efficient use of irrigation water. Discussion with farmers 16 revealed that they are partially aware of water conservation techniques and the linkages sustainability but less aware of the details and the opportunities of new ideas. 1. Crops 113. There are various cropping options to reduce water demand; these include a move to high yield shorter duration crops as well adjustments to the planting calendar to optimise the use of the rainfall. With the present fixed electricity rates for pumping, there is no real incentive to economise on pump use. The PRA conducted for the study identified some reluctance to change to short term high yield crops due to uncertainties in the irrigation supplies-for the groundwater erratic power was quoted as an issue. 114. Delayed monsoon planting offers opportunities to better use the effective rainfall and consumptive use. From an analysis of the effective rainfall and potential evapotranspiration shown in the sub-basin profile shows the very large additional water consumption if farmers plant before June as shown in Figure 39. The net of saving in demand between planting in June as opposed to May would be about 200mm. 16 NAPPC S-NWM Participatory Rural Appraisal 2011 59

There are several schemes under which subsidy are provided by the government to the farmers for construction of ponds in their fields‘ like Khet Talab Yojna, construction of small tank under Micro- Minor irrigation, Balram Talab Yojna. The water conserved in the ponds provides irrigation to the farm lands and effective groundwater recharge has also been observed. The objective of this scheme is to conserve rainwater in the field for irrigation. For digging ponds under Balram Tal Yojana, every beneficiary is given 25% subsidy, the upper limit of which is Rs 50,000. The benefit of the scheme is given to the applicants registered after May 25, 2007. The tanks are becoming more popular. There is, however, some reservation from smaller farmers who have to allocate scare land for the tanks. The tanks are most effective on the areas of black cotton soils. 116. Balram Talabs are larger water tanks, which can irrigate up to 50 hectare area, the uptake has been good with a reported 7500 tanks constructed to date. Mulching of crop fields is also becoming popular, which helps in soil moisture conservation and high reduction of water demand by the crops. 3. Micro Irrigation 117. Micro- irrigation schemes are also becoming popular in the basin. A field study by India Institute of Management (IIM), Indore on ‗Impact Assessment of Micro Irrigation schemes in Madhya Pradesh‘ reveals that financial benefits of micro irrigation scheme to the farmers outweigh the cost involved in addition to big water savings. The programme started in 2008 with a 40% subsidy from central government and initially progress was slow. The state has added a 30% subsidy for general farmers and 40% subsidy for small farmers and since then the uptake has increased. The promotion of the drip is being supported by the private sector suppliers; farmers are allowed to select from a list of fifty five suppliers. A precision farming development centre has recently been established in Bhopal. The farmers are using the drip to grow a wide range of crops including crops not normally considered so suitable with drip. It is reported that there is no real evidence that farmers are switching their cropping. The growth of sprinkler has exceeded drip but this is thought to be the cheaper cost of sprinkler over drip; however, from studies the productivity of the drip is higher than the sprinkler. 118. The major benefits include: o Water usage improved by more than 2.5 times. Water saving of about 50% observed in many cases. o Increase in the revenue from agriculture, about 20% reduction in labour cost. o 30% to 50% reduction in fertilizer and pesticide usages. o About 20% saving in power bills. o 2-3 times increases in crop yield for many crops. 60
