Effect of micronutrients (Mg, Zn & B) on yield contributing characters of Sweet corns

Abstract

The experiment was conducted on experimental site of Wheat and Maize Research Unit, VNMKV, Parbhani during kharif season 2016-17. The soil was medium black with moderate moisture retention capacity. The land having uniform topography was used to study the responses of micronutrient’s (Mg, Zn and B) to crop hybrid (Phule Madhu) under irrigated condition, by using soil and foliar application of (Mg, Zn and B) micronutrients in presence of RDF @ 120:60:50 NPK kg/ha. The experiment was laid out in RBD with three replication and ten treatments. Yield contributing parameter such as cob length, cob girth, cob weight with husk/ without husk, cob yield plot-1 and cob yield ha-1 also were recorded and data was analyses statistically. Among all the treatment T7 (RDF + MgSO4 + ZnSO4 + B spraying @ 1% at 30 and 45 DAS) (41.93 kg plot-1 and 436.80 q ha-1) showed higher in yield which was at par with treatment T8 (RDF +Mg @ 1% spraying at 30 and 45 DAS) and significantly superior over rest of treatments. Among all the treatment T7 (RDF + MgSO4 + ZnSO4 + B spraying @ 1% at 30 and 45 DAS) showed higher cob yield (41.93 kg plot-1) and yield attributing character over the rest of the treatments. Application of micronutrients through foliar sprays gave significant results as compared to soil application under irrigated condition.
