Abstract

Malnutrition and water saving are the two biggest challenges for the rice farmers in developing countries. To produce more rice with little water seems an attractive practice for the farmers in Pakistan which may increase the problem of malnutrition on low zinc soil. Zinc as an essential nutrient needs special attention for successful management in rice crop production when transitioning from flooded to aerobic cultivation systems. In this experiment several methods of zinc fertilization were assessed: Seed priming, soil application, foliar application, seed priming + soil application, seed priming + foliar for their effect on rice productivity under aerobic culture. Results revealed that all methods of zinc fertilisation improved the crop yield while the best results were found using a combination of seed priming and foliar application. Furthermore, this technique significantly enhanced the zinc bioavailability in both cultivars. We conclude that rice productivity and quality can be enhanced with zinc seed priming supplemented with foliar application grown under aerobic rice culture.
