Abstract:

Field experiment was conducted at wetland of Agricultural College and Research Institute, Madurai, during the kharif and rabi season of 2016-17 to study the effect of age of seedling and split application of nitrogen in machine transplanted rice. The three seedlings viz., 14, 18 and 22 days old seedlings were transplanted to the main field by using rice transplanter and four levels of nitrogen were applied in the sub plots (120 kg ha-1 N in 3 equal splits and 150 kg ha-1 N in 3, 4 and 5 equal splits). The maximum number of productive tillers was recorded in 18 days old transplanted seedlings with 150 kg ha-1 N in four splits than that of other treatment combinations. The higher stem borer incidence was recorded in transplanting of 18 days old seedlings with 150 kg ha-1 N in three splits. The reduced stem borer infestation was increasing under the number of N splits machine transplanted condition.
