Description Journal article
Non-availability of water during post-monsoon and summer seasons is a major
impediment to crop production in upland areas. Keeping this in view, a study
was conducted to evaluate the impact of integrated water resource development
and management strategies on agricultural production in a plateau area of
Sundargarh district, Odisha. For development of water resources, flow
regulating devices like inlet, outlet and surplus escape were designed and
irrigation project (MIP) of the study area, based on the drainage coefficient of
136 mm d-1. A dug well of 6.0 m outer diameter and 9.0 m depth was also created
along the drainage line adjacent to the canal linked service reservoir. Based on
the available water resource, an area of 1.1 ha was selected for growing different
crops (kharif rice, mustard in rabi and groundnut and green gram in summer)
under the study. The pipe conveyance system coupled with sprinkler irrigation
was laid out for irrigating the crops in the area. The flow regulating pattern in
the outlet device and surplus escape were observed in sub-critical flow range.
The hydraulic evaluation of dug well indicated that drawdown of the well
was 36 cm hr-1 when a 5 hp pump was used in pumping with recuperation rate
of 3.0 cm hr-1. With using 6300 m3 water from the well as supplemental irrigation
(4 numbers) during dry spells, the yield of rice could be increase by 32%
compared with non-irrigated rice in monsoon season. Among different
irrigation methods (check basin, furrow and sprinkler), sprinkler irrigation
saved 30-33% irrigation water with producing 24-27% higher yield, resulting in
84% improvement in water productivity compared with check basin irrigation
in groundnut and green gram. The net economic water productivity could be
achieved as ` 1.14 m-3, ` 5.93 m-3, ` 8.03 m-3 and ` 5.38 m-3 for paddy, rapeseed,
groundnut and green gram crops, respectively under irrigation. Further,
pisciculture taken up in the service reservoir showed that after 210 days of
rearing of fish fingerlings, the average mean body weight (MBW) obtained as
17.5 g, 11.5 g and 12 g for catla, rohu and mrigal, respectively with total harvested
biomass of 2.57 t ha-1. Overall, the development and management of surface and
groundwater resources and its efficient management helped in bringing
diversification in crop production integrating with pisciculture which resulted
higher profit in farming in an upland plateau area of the study region.
