     Policy Recommendations
         Importance of drip irrigation
• Water is supplied through a network of pipe using
  dripper/emitters.
• Water is supplied at a regular interval and at a required
  time/ quantity.
• Since evaporation and conveyance losses are negligible,
  water use efficiency under DMI is over 90%.
• Productivity gains through DMI varies from 20% to about
  50% depending upon the crop.
• Mostly useful to wide spaced crops
• Importantly, under DMI system, water is supplied to the
  crop but not to the land.
     Area and crops covered under DMI
• As per INCID report, about 80 crops are suitable for
  drip method of irrigation.
• Almost all the fruit and vegetable crops, coconut,
  cotton and even some oilseed crops are highly suitable
  for DMI.
• Area under DMI increased from around 500 ha during
  early 1980s to about 3.50 lakh ha in 2000 in India.
• Maharashtra state alone accounts for over 50 of
  India’s total area.
• The important crops that are cultivated under DMI in
  Maharashtra are grapes, banana, s.cane, pomegranate,
  mango, etc.
           Subsidy Schemes for DMI
• Both Central and state subsidy schemes are available for
  adopting DMI in India.
• Maharashtra started providing subsidy since 1985-86
  onwards.
• Central subsidy schemes started during the year 1990-
  91.
• Except Maharashtra, other states do not have state
  subsidy schemes for DMI.
• Subsidy varies with farmers landholding size. However,
  50% of capital cost is provided as a subsidy for farmers
  who adopt drip method of irrigation.
• Central scheme does not provide subsidy to sugarcane
  crop.
               Field Level Results

• Field level studies are not available for different
  states.
• We have carried out three different studies on
  grapes, banana and sugarcane using data collected
  from Maharashtra.
• Our focus was to estimate the economic viability
  of DMI under with and without subsidy condition.
• We have compared the drip farmers with the non-
  drip farmers in different parameters.
     DMI impact on cost of cultivation

• On an average DMI reduces total cost of
  cultivation by 15 to 20%.
• However, it significantly varies with
  operation.
• Cost saving is found to be higher in
  operations like weeding, irrigation,
  ploughing and even in fertilizers.
        Water use efficiency/Water saving

• Water saving varies from 25 percent to 35 percent
  among the three crops considered for analysis.
• Water saving is found to be very high in
  sugarcane,which is a water intensive crop.
• Water required to produce per unit of output is
  very low under DMI compared FMI in all three
  crops.
• From the saving of water farmers were able to
  bring additional irrigated area to tune of 1.3 acres
  from every ha of DMI.
            Productivity increase


• Productivity of crops cultivated under DMI is
  higher by about 20-35 percent when compared to
  the crops that are cultivated under FMI.
• Market price realized by the DMI farmers is
  relatively higher because of better quality produce.
             Electricity Saving

• Electricity saving by DMI has not been
  studied by the researchers.
• By reducing the consumption of water and
  working hours of pumpsets, DMI could
  save about 1200-1500 kwh/ha electricity.
• Electricity use efficiency is also very high
  under DMI compared to FMI.
              Economic viability of DMI

• BC ratio and NPW were estimated using discounted cash flow
  technique with different rate of discounts (10%, 12% and
  15%) under with and without subsidy condition.
• Investment on DMI is found to be economically viable in all
  three crops. BC ratio varies from 1.78 to 2.80 under different
  discount rates.
• Investment on DMI is also found to be economically viable
  even without subsidy.
• NPW calculation shows that the farmers cultivating grapes
  and banana will be able to pay back the entire capital cost
  from the first year profit itself.
              What needs to be done?
• Statewise potential and required investment for DMI need to be
  estimated.
• Measures need to be introduced to reduce the capital cost.
• Structured subsidy schemes followed in Maharashtra should be
  introduced in other states.
• Better awareness about the DMI should be created among the farmers
  through quality extension network.
• Differential subsidy rate should be followed: higher subsidy rate for
  water intensive crops and vice-versa.
• Cultivation of sugarcane should be promoted using DMI with the help
  of sugar factories.
• Drip set manufactures should be asked to involve in providing training
  to the farmers who are ready to adopt it.
