Abstract:

The impact of graded levels of Cu (0, 0.5, 1.00, 1.50, 2.00, 2.50 kg ha-1) on the growth and yield of irrigated rice was studied by conducting field experiments in major rice growing tracts having varied soil Cu status at Tamil Nadu. The treatment plots were replicated four times in Randomized Block Design. Application of Cu @ 1.5 kg ha-1 recorded the highest plant height (95.0 cm), number of productive tillers m-2 (323.6), number of filled grains panicle-1 (107.6), test grain weight (24.5 g), grain yield (6.50 t ha-1) and straw yield (7.74 t ha-1). The highest values were recorded in the location No.4 where the initial soil Cu content was minimum (0.84 mg kg-1). The results indicated that, the Cu fertilization significantly increased the growth and yield parameters of rice crop in Cu deficient soils while the soils with adequate or high Cu status showed declining response.
