Abstract: A pot experiment was conducted at pot culture yard in Department of Agricultural Chemistry and Soil Science, R.B.S. College Bichpuri, Agra (UP). To study the interaction effect of (Fe × Mn) on yields, chemical composition of plants at different growth stages and uptake of nutrients by grain and the straw at maturity by spinach crop. Four levels (0, 5, 10, 20 ppm) of each iron and manganese were evaluated in factorial design with three replications. The results indicated that the interaction of effect of (Fe × Mn) on yields was found to be significant. The maximum values (19.5, 49.0 mg/pot) of green foliage and dry matter (2.4, 5.6 mg/pot) were noted under 10 ppm Fe + 10 ppm manganese dose. The highest dose (20 ppm iron and 20 ppm manganese) reduce the yields upto minimum levels. Nutrient composition of spinach plants grain and straw in respect of N, P, Fe, Mn content was consistently increase up to (10 ppm) dose of iron and manganese level. Thereafter, a deduction was noted with higher dose (20 ppm) iron and manganese. Similar tend was noted in case of nutrients uptake by spinach plants. It is concluded from the results that (Fe × Mn) with dose of 10 ppm was found to significantly superior over rest of the combinations. Investigations also revealed that Fe and Mn has antagonistic relation in respect their content and uptake in all the growth stages of spinach plants.
