State of the Basin Report - 2003application. 48 There are three main rice cropping patterns based on generalised land types. 49 Lowerpaddy land is planted annually with paddy rice in the wet season and is at risk of flooding andtemporary water logging. Middle paddy land is the most productive, with better water control andreduced flood risk. In upper paddy land, short duration rice is planted in only three or four years outof ten. Upland crops are cultivated at other times, and farmers face major problems with weedmanagement. All three cropping systems use bunded planting, which involves the construction ofsoil embankments around rice plots to retain water.Table 5.
