Field experiments were carried out at Tamil Nadu Agricultural University, Coimbatore, India during samba (August-December) seasons of 2012 and 2013 to find out the optimum crop geometry, age and number of seedlings on growth and physiological characters in relation to yield of low land rice. The experiment consisted of three mainplot treatments viz., M1–25 x 25 cm, M2–25 x 20 cm and M3–25 x 15 cm and six sub-plot treatments S1–14 day old seedlings (DOS)+1 seedling/hill, S2–14 DOS+2 seedlings/hill, S3–14 DOS+3 seedlings/hill, S4–21 DOS+1 seedling/hill, S5–21 DOS+2 seedlings/hill and S6–21 DOS+3 seedlings/hill and replicated thrice in a split plot design. The treatment combination of M3S5 (25 x 15 cm spacing and 21 DOS with two seedlings hill-1) recorded higher nitrogen uptake than others at panicle initiation, flowering and harvest stages. The same trend was followed on phosphorus and potassium also.
