Zinc uptake and utilisation in wetland rice as influenced by zinc sources

Soil application of Zn is by far the most common and generally successful method of application to rice. Comparison of the effectiveness of soil applications of Zn necessarily involves simultaneous comparison of different sources. Applying Zn in combination with macronutrient fertilizers is convenient and allows more uniform distribution. Studies have indicated marked differences in Zn availability, uptake and utilisation resulting from the macronutrient fertilizer with which it is applied. This study was undertaken to evaluate the effect of a few sources of Zn on the yield, Zn uptake and utilisation in rice in two major rice grown soil series of Tamil Nadu. (author). 7 refs., 3 tabs
