Abstract: Field experiments were conducted at Department of Agronomy of Tamil Nadu Agricultural University, Coimbatore to study the effect of spatial arrangement and nitrogen scheduling on N uptake and crude protein content in maize. The experiments were laid out in split plot design and replicated thrice. The following spatial arrangements viz., 60 x 25, 30 x 30, 35 x 35, 40 x 40, 45 x 45 and 50 x 50 cm were alloted to main plots. Three nitrogen scheduling approaches were assigned to sub plots. Growth stage based N scheduling approaches were compared with Leaf Colour Chart based (LCC) N management. Based on the experimental results, N uptake was higher under 30 x 30 cm arrangement throughout growth stage and reached maximum at 90 DAS ( 290.2 and 307.9 kg ha-1). Among N schedling approaches, LCC based N scheduling removed more N (261.6 and 284.2 kg ha) at 90 DAS than conventional approach. Similarly LCC based N management resulted more crude protein (7.68%) content in maize.
