Abstract
Zinc (Zn) is critically required by plants, animals and human beings. About one third of total world's poor population is at the high risk of Zn deficiency because they rely on cereals for their daily caloric intake. By keeping in mind this scenario it is hypothesized that the use of ZnO (a cheap source of Zn) impregnated urea for rice may enhance Zn contents in grains. Three types of urea were prepared including bio-activated Zn coated, Zn coated and Zn blended urea. The bio-activated Zn coated urea was prepared by inoculating the powdered organic material with Zinc solubilizing bacterium and then this material was mixed with ZnO. This bio-active Zn was coated on urea at three rates to formulate 0.5, 1 and 1.5% bio-activated Zn coated urea. Moreover, Zn blended urea was prepared by mixing powder ZnO with urea. The comparative efficacy of different types of Zn impregnated urea were compared with ZnSO4 to enhance growth, yield and grains Zn concentration of rice grown in pots. The results showed that 1.5% bio-activated Zn (ZnO) coated urea performed better in promoting growth, yield and grain Zn content than other treatments. About 15 to 20% increase was observed in yield and grain Zn concentration. This suggests that the application of 1.5% bio-activated Zn coated urea is highly effective in enhancing growth, yield and quality of rice.
