Response of bread wheat (Triticum aestivum L.) to varied levels of iron and zinc enriched with organics in maize-wheat cropping sequence

T.T. Bandiwaddar, B.N. Patil

Abstract


A field experiment was conducted  at Agricultural Research Station, Kalloli, University of  Agricultural Sciences, Dharwad for two years (2012-13 and 2013-14) under irrigated condition to study Response of bread wheat (Triticum aestivum L.) to varied levels of Fe and Zn enriched with organics in maize-wheat cropping sequence. The results of the experiment indicated that, application of RDF + FYM + Enriched FYM (500 kg ha-1) with 6 kg FeSO4.5H2O + 4 kg ZnSO4.7H2O ha-1 (S3) recorded significantly higher grain (48.01 q ha-1) and straw yields (82.29 q ha-1) of wheat as compared to rest of the enrichment treatments. This higher yield is due to significantly higher values of growth and yield components viz., LAI (3.18), total dry matter production (168.87 g 0.5 m-1 row length), number of ear heads (87.87 0.5 m-1 row length) and 1000-Grain weight (46.44 g) under the treatment. Further, significantly higher Gross returns (` 109088 ha-1), Net returns  (` 71266 ha-1) and BC ratio (3.31) were recorded due to application of RDF + FYM + Enriched FYM (500 kg ha-1)  with 6 kg FeSO4.5H2O + 4 kg ZnSO4.7H2O ha-1 (S3) as compared to rest of the enrichments.
