Abstract:
The field experiment has been conducted during 2020-2021 on the basis of Randomized plot design with three replication at Agricultural College & Research Institute, Madurai. Treatments consists of direct sowing, transplanted control, seedling root dipin IBA (50 ppm), seedling root dip in NAA (50 ppm), foliar spray of salicycilic acid (100 ppm), TIBA (50 ppm), PPFM (2 percent). Foliar spray has been imposed on 20 and 40 days after transplanting. The growth, total chlorophyll was taken on 55 days after transplanting. Comparing the seven treatments, foliar application of TIBA (50 ppm) recorded the highest value in plant morphological characters viz., root length (cm), number of branches, plant width at base (cm) and biochemical parameters of total chlorophyll content (mg g-1), Soluble protein content (mg g-1) and nitrate reductase enzyme activity (µg g-1). Besides, the reduction in plant height (cm) was noticed by the foliar application of TIBA (50 ppm) than the other treatments. The yield and yield characters were recorded after harvest. Among the treatments, foliar application of TIBA (50 ppm) maintained its superiority in number of capsules plant-1, 1000 seed weight and yield (kg ha-1).
