Effect of zinc and iron enriched organics on yield and economics of kharif sorghum

Abstract

Influence of zinc and iron enriched organics in kharif sorghum was evaluated during kharif season of 2017 at AllIndia Coordinated Sorghum Improvement Project (AICSIP), Main Agricultural Research Station, Dharwad (Karnataka).Results of the experiment indicated that application of ZnSO4 + FeSO4 @ 15.00 kg ha-1 each enriched with FYM recordedsignificantly higher grain yield (4,132 kg ha-1), fodder yield (9.95 t ha-1), gross returns (` 63,657 ha-1), net returns (` 20,890ha-1) and BC ratio (1.49). Similarly, the same treatment recorded significantly higher zinc (23.43 and 20.64 mg kg-1) and iron(33.89 and 30.67 mg kg-1) content in grain and fodder respectively as compared to control, recommended dose of fertilizerand recommended package of practices. Growth and yield indices like plant height (232.7 cm), total dry matter production(218.7 g plant-1), grain weight (63.5 g plant-1) and test weight (3.02 g) were also higher with the same treatment.
