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. The biometric observations i.e. plant height at flowering and harvesting (cm), chlorophyll index (SPAD), days to 50 % tassels & silk (DAS), cob height (cm) at flowering & harvesting and leaf area (dm²) at flowering & harvesting. Results for days to 50% pollen shedding, days to silking, plant height differences and cob height differences were found non -significant. The results for leaf area (dm²) were found significant at flowering and at harvesting results were found significant. It is apparent from the data that significantly highest leaf area was attained by plants under treatment T₇ (RDF+ Mg + Zn+ B @ 1% spraying 30 and 45 DAS) at both growth stages than treatment T₁ (control) and T₂ (RDF 120:60:50 kg NPK ha^-1) and at par with rest of the treatments. The differences for chlorophyll content were found significant. The chlorophyll content in leaves was progressively increased with advancement in growth period and the maximum was attained at flowering stage and also the chlorophyll content was recorded the highest in treatment T₇ (RDF + Mg + Zn + B @ 1% spraying at 30 and 45 DAS) (64.87 SPAD) followed by T₈ (RDF +Mg @ 20 kg ha^-1 1% spraying at 30 and 45 DAS) (64.19 SPAD) and T₉ (RDF+ Zn @ 20 kg ha^-1 1% spraying at 30 and 45 DAS) (63.36 SPAD) and significantly superior over rest of the treatment.
