Abstract: An experiment was carried out under sandy loam soil at Tamil Nadu Agricultural University, Coimbatore, during Rabi and summer seasons of 2016-17 and 2017-18 to study the effect of crop geometry, nitrogen and iron nutrition on weeds and yield of babycorn (Zea mays L.). Weed density and drymatter was significantly lower with 45 × 15cm spacing and application of 100% recommended dose of nitrogen (RDN). Higher babycorn yield was realized with the babycorn raised at 45 × 15cm while the nutrient treatments did not differ significantly with the babycorn yield. However interaction effect was found to be conspicuous wherein application of 125% RDN with FeSO₄ foliar spray @ 1% at 30 and 45 DAS to the babycorn raised at 45 × 15 cm gave higher yields and was at par with the other fertilization levels of babycorn sown at the same crop geometry level.
