3.3 Sampling design
For the present study, multistage sampling procedure was adopted. In the first stage,
based on the criterion of availability maximum number of farm-ponds in each of the subwatersheds
in Dharwad district i.e. one sub-watershed in Dharwad taluk and another subwatershed
from Kalaghatagi taluk were selected for the study.
In the II stage, one micro-watershed from each of the two selected sub-watersheds
were considered. Accordingly Managundi micro-watershed in Managundi SWS and Tamarikoppa
micro-watershed from Galagi SWS were chosen.
In the final stage, from selected two MWS, 25 per cent of the farmers were randomly
selected from each MWS based on the availability of farm- ponds located on their fields to
make a sample size of 45 and for comparison purpose another sample of 45 farmers who do
not possess farm-ponds i.e. without farm-pond were randomly interviewed. Thus, total sample
size constituted 90 farmers (Table 3.6).
3.4 Collection of data
The required data for the study included both secondary and primary data. Secondary
data on the extent of various rainwater harvesting structures as well as their construction
costs etc. were collected from the District Watershed Development Office (DWDO), Dharwad,
lead NGO (IDS) of Sujala watershed and also from sub-offices of Managundi and Tumarikoppa
villages.
The primary data on household composition, land holdings, farm machinery and
equipments, livestock, cropping pattern, cost and returns of different activities were collected
from the selected 90 sample farmers of both with and without farm-pond areas. Primary data
related to the agriculture year 2003-04 was elicited using pre-structured and pre-tested
schedules.
3.5 Analytical tools employed
Following different methods were employed to analyze the data, interpret the results, to draw
inferences and to design policy options for adoption by farmers, researchers and
Government.
3.5.1 Conventional analysis
Tabular presentation technique was employed including percentages and averages in
respect of socio-economic features of sample farmers, cropping pattern, input usage, cost of
cultivation and returns etc. for both the sample farmer’s group, to facilitate comparison
between With and Without farm-pond areas.
3.5.2 Cost of cultivation and returns
3.5.2.1 Cost concepts
The cost of cultivation per hectare of all the crops cultivated in both with farm-pond
and without farm pond areas were calculated according to cost concepts used in Farm
business analysis for the data pertaining to the crop year 2003-04.
Cost A: For computing Cost A, following items of expenditure were included and aggregated.
Wages of hired human labour
Charges of owned and hired bullock labour
Charges of owned and hired machine labour
Value of seeds (both farm produced and purchased)
Value of manures, fertilizers, seed treatment and plant protection chemicals
Depreciation of farm implements, machinery, farm buildings etc.,
Land revenue
h. Interest on working capital.
Cost B: This was computed by adding the following items to cost A,
Rental value of owned land
Interest on fixed capital
Cost C: This was worked out by adding the value of imputed human labour supplied by the
family and marketing cost to Cost- B, the value of imputed human labour was taken at the
prevailing wage rate for hired labour.
