Effect of foliar spray and sources of zinc on yield, zinc content and uptake by rice grown in a vertisol of central India
Author(s): PS Kulhare, GS Tagore and GD Sharma
Abstract: A field experiment was conducted in kharif during 2010 and 2011 to study the effect of foliar spray of 0.5, 1.0% Zn salts and 1.0% Zn salts +0.5% lime concentration of different sources of Zn (ZnSO4.7H2O, ZnCl2, Zn3(PO4)2, ZnO and Na2Zn-EDTA) on yield, Zn content, uptake and Zn use efficiency in rice (Pusa Basmati) grown on Typic Haplusterts. The rice grain yield significantly increased with the foliar application of Zn-EDTA over all the sources of Zn but the other Zn sources were found on par amongst themselves. While the Zn content in grain and straw with Zn3(PO4)2 and Zn EDTA was found significantly superior to ZnCl2 except Zn content in straw with Zn3(PO4)2. The Zn uptake by grain with ZnSO4.7H2O, Zn3(PO4)2, ZnO and Zn EDTA were also found significantly superior to ZnCl2 but the sources of zinc were found non-significant for Zn uptake by straw and total Zn uptake. The Zn use efficiency by Zn EDTA and ZnSO4.7H2O was found significantly superior to ZnCl2, Zn3(PO4)2 and ZnO. However, the Zn use efficiency with Zn EDTA was also found significantly higher than ZnSO4.7H2O. Foliar application of 1.0% zinc salts was found significantly superior to 0.5% Zn salt for yield, Zn content and uptake. However, the Zn uptake with 1.0% zinc salts was found significantly higher than 1.0% zinc salts+0.5% lime application. The zinc use efficiency with 0.5% Zn salt was found significantly higher than 1.0% Zn salts+0.5% lime but 0.5% Zn salt was found on par with 1.0% Zn salts for available Zn.
