Tumkur, Karnataka

In the district, horticulture crops occupy a relatively high proportion of gross cropped area, raising the economic viability of solar pumps here. For average crop revenue per holding, the district appears among the top 25 percentile of districts, implying higher investment capacity of the farmers here. The district appears in the group of districts, which are (very) highly vulnerable towards climate change, as per an index constructed by CRIDA.

Deployment Approaches

Individually owned off-grid solar pumps

Limited Suitability

The district has a relatively high disbursement of institutional credit and high crop revenue per holding. However, ground water availability is below the safe limit, and concentration of diesel pump users is comparatively low, making it very difficult to promote the private ownership of solar pumps here.

Solarisation of feeders

Suitable

Given the relatively high cost of power supply for the respective DISCOM, a comparatively high extent of feeder segregation, and a high penetration of electric pumps, solarisation of the feeders would be a recommended way to promote solar-powered irrigation in the district. It would ensure the rapid and cost effective solarisation of irrigation power at a large scale.

Solar based water as a service

Not Suitable

The district has a relatively high proportion of unirrigated area. But, the concentration of small and marginal farmers is rather low and groundwater availability is below the safe limit, making it very difficult to promote solar-based irrigation through the water-as-a-service model here.

Promote 1 HP and sub-HP pumps

Limited Suitability

The district has a comparatively high disbursement of institutional credit to marginal farmers and a relatively high proportion of horticulture crops under gross cropped area. But groundwater availability below safe limit and a rather low concentration of marginal farmers limits the demand for 1 HP and sub-HP pumps in the district.

Solarisation of individual grid-connected pumps

Limited suitability

The district has a relatively high rate of power subsidy for agriculture consumers, a comparatively high extent of feeder segregation, and a high penetration of electric pumps. However, the groundwater availability is below the safe limits. State should be cautious in promoting solarisation of individual grid-connected pumps as it may aggrevate the groundwater depletion

Leveraging Solar Pumps to Promote Policy Objectives

If you are deploying solar pumps in this district then you can further these policy objectives.

Har Khet ko Pani

A relatively high proportion of the net sown area in the district is unirrigated, indicating high irrigation demand. Solar pumps can help improve access to underground irrigation as part of Har Khet ko Pani.

Doubling Farmers’ Income – Crop Intensity

A relatively high proportion of the district’s net sown area is unirrigated. Lack of access to irrigation is one of the major barriers to growing crops beyond two conventional seasons, rabi and kharif. Ensuring irrigation access through solar power will help improve cropping intensity and move towards the aim of doubling farmers’ income by 2022.

Per Drop More Crop

In the district, crops suitable for drip and sprinkler irrigation occupy a relatively high proportion of gross cropped area, making it easy to adopt such high precision irrigation methods. Solar pumps, along with other efficient and precise water application devices, could be deployed under Per Drop More Crop to promote efficient irrigation.
