AbstractA field experiment was conducted at the main Field Station, Department of Agriculture, Lovely Professional University, Phagwara, Punjab during session 2018-2019 on sandy loam soil with ph 7.41 and Ec 0.35(ds m-1). The study was done to evaluate the “Effect of Fly ash and micronutrients (Zn and Fe) on yield of maize crop.” Pioneer 3401 hybrid variety was used. The experiment has seven treatments T1 (RDF), T2(Fly ash 10 t ha-1), T3(RDF + Zn EDTA 12%), T4(RDF + Fe EDTA 12%), T5(RDF + Fly ash 10 t ha-1+ Zn EDTA 12%), T6(RDF + Fly ash 10 t ha-1+ Fe EDTA 12%) and T7(RDF + Fly ash 10 t ha-1 + Zn EDTA 12% + Fe EDTA 12%) and was arranged in RBD design. The different parameters of growth and yield were evaluated. It was reported that T7 shows the maximum records of Number of cobs per plant (1.73), cob length (18.17 cm), cob weight (141.57 g), grains per cob (339.86), cob girth (14.03 cm), grain rows per cob (13.26), 100 seed weight (26 g) and seed yield (70.27q/ha).The least was recorded from T1 treatment. The yield of a crop has shown more responses to the combine application of RDF, Fly ash and foliar spray of Zn and Fe. The combination of fertilizers has an anticipated command on maize cultivar.
