An experiment was conducted in the instructional farm of KVK, West Tripura during rabi season of 2014-15, with an objective to find a proper dose of NAA to control premature flower and fruit drops in chilli. The growth regulator (NAA) was sprayed two times once at 35th and second at 45th days after transplanting. The treatment comprises of T1: NAA @ 5 ppm, T2: NAA @ 10 ppm, T3: NAA @ 20 ppm, T4: control. The result of the experiment revealed that NAA application significantly influences the yield attribute of chilli. It was observed that maximum plant height (39.45 cm), maximum number of branch per plant (18 nos.), maximum numbers of chilli per plant (250 nos) and highest yield (11.2 t/ha) was recorded in T3 followed by T 2 and lowest was in case of control.
