Description Not Available
By virtue of its geographical position and varied terrain and climatic zones, a rich diversity of inland
and coastal waterlogged and wetlands are available in India. The saucer shaped landform, high rainfall
due to southwest monsoon (June-September) and poor drainage condition make certain parts of east
coast of India susceptible to waterlogging during rainy season. On the other hand, after receding flood
the land remains dry from January to May. As a case study, development and management strategies of
seasonal waterelogged coastal areas of Puri district of Odisha were developed through deep water rice
cultivation, pond based farming and multiple use of water. Based on the rainfall-runoff relationship, it
was observed that flooding was highly dependent on rainfall in the catchments and rice yield production
was highly influenced by time of flooding. Among 3 years (2005, 2006, 2007), no yield was obtained in
2006 due to occurrence of early flood (1st week of July). Performance of improved deep water rice
varieties (Hangseswari, Sabita, Ambika, Saraswati) was compared with that of two local varieties
(Bankui and Dhalakaritk) under 3 flooding depths. The net water productivity was enhanced from Rs.
1.22 m-3 through sole rice to Rs. 6.26 m-3 through integrated rice-fish pond based farming
