The field study was conducted at Anbil Dharmalingam Agricultural College and Research Institute, Thiruchirapalli during late samba season of 2019-2020 to evaluate the effect of enriched organic manures with different levels of zinc and iron on growth and yield of rice under sodic soil condition. The experiment was laid out in randomized block design with three replications. Three levels of zinc and iron were enriched with three different organic manures. The treatments consisted of recommended dose of fertilizers with enriched poultry manure, vermicompost and farmyard manure each of 500 kg per hectare with 100% Zn & Fe (37.5 and 30 kg /ha), 75% Zn & Fe (28 and 22 kg /ha) and 50% Zn & Fe (18.7 kg and 15 kg /ha) and control i.e. Application of Zn (37.5 kg /ha)+ Fe (30 kg /ha) alone were taken. The enriched organic manures were applied at the time of transplanting of rice. The applied enriched organic manures showed significant impact on the growth and yield parameters of rice. Readings taken at harvest showed that the highest plant height(159.01cm), number of tillers(604 no/m2), root length (25.18cm), dry matter production(12188 kg ha-1), panicles/m2 (479 no/m2), filled grain per panicle(479 no/m2), grain and straw yield (4535 kg ha-1and7259 kg ha-1) were recorded with the application of poultry manure enriched with 100% zinc and iron along with recommend dose of fertilizers over control. This was on par with vermicompost enrichment with 100% zinc and iron. The lowest growth and yield parameters were observed with the control.
