Abstract: A field experiment was conducted in farmers’s field at lalapuram village, Kallikudi block, Madurai District Tamil Nadu with test crop of barnyard millet during the Kharif season in the year 2018-19 in Typic Haplustalf soil to study the impact of NPK levels and iron fertilization on grain yield of barnyard millet cultivars. Twenty four treatment combinations were tested in factorial randomised design with two replications. Among the two barnyard millet cultivars (MDU-1, ACM-15-353), MDU-1 (2590 Kg ha-1) produced significantly higher yield than the ACM-15-353 (2108 Kg ha-1). Experimental results revealed that application of 100% FeSO4 soil application + Foliar spray of 0.5% FeSO4 and 125% soil application FeSO4 + Foliar spray of 0.5% FeSO4 along with 100% NPK produced higher grain yield in the both the cultivars. Iron management at the rate of 100% FeSO4 (50 kg ha-1 soil application) + Foliar spray of 0.5% FeSO4 at vegetative and panicle initiation stages (Fe4) recorded 20% increase over Fe1 (no iron) in MDU-1 with 100% NPK. While with 75% NPK, Fe6 (125% FeSO4 (62.5 kg ha-1 soil application) + Foliar spray of 0.5% FeSO4 at vegetative and panicle initiation stage) recorded 14% increase over Fe1 (no iron) in MDU-1. Percentage increases in yield of 22% was recorded under 100% NPK by Fe6 (soil application of 125% FeSO4 (62.5 kg ha-1) + Foliar spray of 0.5% FeSO4 at vegetative and panicle initiation stages) in the ACM-15-353 cultivar, while at 75% NPK Fe6 (soil application of 125% FeSO4 (62.5 kg ha-1) + Foliar spray of 0.5% FeSO4 at vegetative and panicle initiation stages) recorded maximum yield.
