The experiment was laid out in randomized complete block design with three replications consisting of eleven treatments with varied levels of ZnSO4 and FeSO4 enriched with organics viz., FYM and vermicompost. Soil application of ZnSO4 + FeSO4 @ 15.00 kg ha-1 each enriched with FYM recorded significantly higher plant height (232.7 cm), total dry matter production (218.74 g plant-1), ear weight (100.4 g plant-1), grain weight (63.5 g plant-1), test weight (3.02 g), grain yield (4,132 kg ha-1), fodder yield (9.26 t ha-1), net returns (` 20,890) and benefit cost ratio (1.49) as compared to control, recommended dose of fertilizer and recommended package of practices. Soil application of ZnSO4 + FeSO4 @ 15 kg ha-1 each enriched with FYM recorded significantly higher zinc content in both grain (23.43 mg kg-1) and fodder (20.64 mg kg-1) which was 16.0 and 22.7 per cent higher over control (19.68 and 15.48 mg kg-1 in grain and fodder, respectively), 12.2 and 20.0 per cent higher over recommended dose of fertilizer (20.56 and 16.51 mg kg-1 in grain and fodder, respectively) and 2.1 and 4.3 per cent over recommended package of practices (22.93 and 19.74 mg kg-1, respectively) (Table 3). Similarly, iron content in grain and fodder was significantly higher with application of ZnSO4 + FeSO4 @ 15 kg ha-1 each enriched with FYM (33.89 and 30.67 mg kg-1, respectively) which was 14.5 and 20.5 per cent higher over control (28.25 and 24.37 mg kg-1 in grain and fodder, respectively), 14.2 and 12.5 per cent higher over recommended dose of fertilizer (29.08 and 26.85 mg kg-1 in grain and fodder, respectively) and 10.3 and 11.0 per cent higher over recommended package of practices (30.40 and 27.27 mg kg-1 in grain and fodder, respectively).EnglishThesis
