Response of irrigated rice to applied zinc under varying available zinc status of rice soils in Tamil Nadu


Author(s): Angelin Silviya R and P Stalin

Abstract: Field experiments were conducted in the major rice growing tracts having varied soil Zn status to study the effect of Zn fertilization in irrigated rice. The treatments consisted of six levels of Zn (0 1.25, 2.50, 5.00, 7.50 and 10.0 kg ha-1) in a Randomized block design. The results revealed that the growth and yield were higher in location 4 where the soil Zn content was minimum (0.87 mg kg -1), compared to locations 6 to 12 where the soil Zn content was comparatively high (0.98 to 2.99 mg kg -1). Averaged for all locations, the application of Zn @ 7.5 kg ha-1 recorded significantly the highest yield of grain (6.81 t ha-1) and straw (8.09 t ha-1). Hence, application of Zn significantly increased the growth and yield of rice in Zn deficient soils, while higher Zn levels showed a decline or no response in soils having high zinc status.
