Abstract:
An experiment was conducted at at the field of Rama University during February to June 2021 to assess the growth and yield performance of brinjal under different level of NAA. The experiment was carried out in Randomized Complete Block Design. There were 5 treatment comprising T1 (0 ppm NAA), T2 (20 ppm NAA), T3 (40 ppm NAA), T4 (60 ppm NAA) and T5 (80 ppm NAA) which was replicated four times. 1-Napthaleneacetic acid (NAA) levels showed significant effect on all growth and yield parameters. The result revealed that highest plant height, number of primary branches/plant, plant spreading, number of leaves/plant, days taken to first flowering, number of flowers/plant, fruit number/plant, average weight of fruit/plant, fruit diameter and total yield among the different treatment were statistically significant. Plot treated with 80 ppm of NAA produced the maximum fruit yield (65.46 t/ha) and had better plant height, fruit length, number of fruit per plant and days taken to first flowering. Maximum plant height (104.48 cm), plant spreading (105.6 cm), number of leaves (162.7) and highest number of primary branches/plant (21.27) was observed in T5 (80 ppm NAA). Fruit length/fruit (13.00 cm), average weight of fruit/plant (1.768 kg) and highest fruit diameter (32.85 mm) was observed in T5 (80 ppm NAA). Thus, appropriate level i.e. 80 ppm of NAA is better for brinjal production at Rama University, mandana, Kanpur condition.
