Zinc availability is one of the major factors affecting rice production and its nutritional quality, which in turn affects human population consuming that rice. Therefore, with an objective to modulate the zinc availability in rice grains, present investigation was undertaken to understand different zinc treatments on grain quality of rice. The data obtained suggested that among the treatments, foliar application, combined with basal application, of zinc was more effective than basal application alone in influencing the growth and nutrition of rice. It increased plant height, number of effective tillers, total dry matter, photosynthetic rate, and grain and straw zinc. In addition, measurement of phytic acid (PA) and PA/Zn molar ratio demonstrated that foliar zinc application caused a decrease in the PA content and reduced PA/Zn molar ratio. Thus, proper management of zinc fertilization can reduce PA content and enhance the bioavailability of zinc in rice grains.
