Effect of foliar application GA3 and NAA on growth and green yield of Coriander (Coriander sativum L.)

Abstract

An experiment entitled “Effect of foliar application GA3 and NAA on growth, green yield and quality of Coriander (Coriander sativum L.)” conducted in season during the year 2024-25 at the experimental field of Department of Horticulture, Faculty of Agriculture,
Tantia University, Sri Ganganagar, Rajasthan, India. The present study aimed to evaluate the Effect of foliar application GA3 and NAA on Growth, Yield and Quality of coriander. The plants were treated with seven different treatments having three replication of each
treatment. The observations were recorded at regular interval. The results of investigation indicated a significant influence on growth, yield and quality of coriander. The maximum plant height at 60 DAS on maximum plant height of (44.21 cm) was noted in T4 treatment
(GA3, 100ppm). The maximum no. of leaves per plant at 60 DAS on maximum no. of leaves per plant of (70.66) was noted in T4 treatment (GA3, 100ppm). The maximum no. of primary branches per plant at 60 DAS on maximum no. of primary branches per plant
of (7.90) was noted in T4 treatment (GA3, 100ppm). The maximum no. of secondary branches per plant at 60 DAS on maximum no. of secondary branches per plant of (14.22) was noted in T4 treatment (GA3, 100ppm). The maximum fresh biomass per plant at 60
DAS on maximum fresh biomass per plant of (31.12 gm) was noted in T4 treatment (GA3, 100ppm). The maximum leaf yield per plant of (114.45 gm) was noted in T4 treatment (GA3, 100ppm). The maximum fresh leaf yield per plot of (3.11 kg) was noted in T4
treatment (GA3, 100ppm). The maximum green yield per hectare of (113.90 q) was noted in T4 treatment (GA3, 100ppm).
