Abstract
The effect of Zn, Fe and Mn on yield and yield contributing parameters and mineral contents of rice variety KS-282 was
studied in the IO-kg sandy clay loam soil pot'. Two rates of Zn (0; 5 and 10 mg kg' soil) and one rate of each Fe and Mn (5
mg kg' soil) along with a basal dose of NPK (100-50-50 mg kg") were added in various combinations before the
transplanting of rice seedlings. Number of tillers pori, number of grains panicle", 1000-grain weight and grain yield
increased significantly with the application of Zn, Fe and Mn alone or in various combinations. However, more increase in
paddy yield and yield contributing growth parameters was noted in treatment comprising 10 mg kg' Zn along with 5 mg kg"
Mn and a basal dose of N. P and K fertilizers. The Zn and Mn concentration in the grain were 46.53 and 99.40 mg kg",
respectively in the treatment, where 10 mg kg" Zn was applied along with NPK+Mn. The maximum Fe was 166.1 mg kg"in
grain, where 5 mg kg'l Zn was applied along with the NPK +Fe.
