Age of seedling

Age of seedling at transplanting has a direct bearing on the yield of the crop. In general, seedling having 3-4 leaves is considered ideal for transplanting.

The optimum age, however, depends upon the duration of variety, season, date of planting, system of raising nursery, tillering habit, inherent fertility and fertilizer management and cultural practices.

Method of planting

Transplanting in rice is done by two methods
