Abstract
Zinc (Zn) is an essential trace element for healthy growth of field crops. Globally, its deficiency limits the production of crops especially rice. Rice is staple foods for populations in many countries, so it is important add adequate Zn sources in rice fields to improve its yield and nutritional status. For this purpose, a field study was conducted in the research area of University of Sargodha, Pakistan to compare the qualitative efficiency of ZnSO4 and ZN-EDTA @ 1% and 2% to improve the growth yield of rice and Zn contents in rice seeds Zn was applied at the time of nursery transplant and flowering stage. Results of this study showed that the addition of Zn-EDTA and ZnSO4 improved the overall rice growth as compared to control treatment. However, use of Zn-EDTA @ 1% proved superior for enhancing the growth, yield and Zn nutrient attributes of rice plants as compared to chemical Zn source. Findings of this study suggested the addition of chelated Zn (Zn-EDTA application @ 1%) to improve the nutrition of rice seeds as well to improve the growth, physiology and yield of rice plants grown in field environment.
