Abstract

Investigation was carried out in the farmer’s field of Kalimpong to evaluate the effect of foliar application of different level of GA3 and micronutrients on Darjeeling mandarin. The experimental design was adopted randomized block design in which there was seven main plot treatments representing combinations of three growth regulators (GA3 @ 7.5 ppm and 15 ppm, BA @ 200 ppm and 400 ppm and 2,4-D @ 7.5 ppm and 15 ppm) and two micro nutrients (Zn @ 0.5% and Boron @ 0.1%). Foliar application of GA3 at the rate of 15 ppm along with zinc (0.5%) and boron (0.1%) improved growth morphology, fruit yield attributes is also effective in enhancing the fruit yield with better fruit quality. Generally, it could be concluded that the treatment (T3) seems to be the promising treatment for the hilly region of Darjeeling.
