Abstract
A field study was conducted during kharif season of 2014 at Agronomy research farm of school of Agricultural sciences and Rural Development (SASRD), Nagaland University, Medziphema to study the effect of spacing and seedling age on yield under System of Rice Intensification. The Experiment was laid out in Split plot design with 3 replications having 3 main plot factors (20 × 20 cm2, 30 × 30 cm2, 40 × 40 cm2) and 4 sub plot factors (9, 11, 13, and 15 days old seedling). The study depicted that plant height, LAI and number of tillers per hill showed an increase in its trend at 30, 60, 90 and 120 DAT. Dry matter accumulation was higher for 20 × 20 cm2 spacing treatment on unit area basis but under per plant basis 40 × 40 cm2 spacing treatment was better. 9 days old seedling planted at 40 × 40 cm2 spacing gave the highest yield (4.35 t ha-1) and harvest index (35.11%) followed by 11 days old seedling (4.25 t ha-1) planted at 30 × 30 cm2 spacing. The straw yield was however found to be inversely related with the grain yield.
