Abstract:
To study growth and yield of cabbage as influenced by GA
and mulching a fieldstudy was carried out at the Horticulture farm of Sher-e-Bangla Agricultural
University, Sher-e-Bangla Nagar, Dhaka-1207 during the period from October 2018to March 2019. Cabbage seeds of Atlas 70 were used as planting materials. Theexperiment consisted of two factors: Factor A: three mulching materials viz. M

= Polythene mulch and M

= Straw mulch and Factor B: Four levels GA

andG

= 120 ppm GA
. The experiment was laid out in a Randomized Complete BlockDesign (RCBD) with three replications. Results revealed that the mulching treatment
M

(polythene mulch) showed promising results on growth and yield parameters
and it was the treatment compared to others which showed the highest marketablecabbage yield (43.03 t ha
-1
) whereas the lowest (40.26 t ha
-1
) was from M
(control
condition). Among the GA
3
treatment, G
2
(100 ppm GA
) gave the best performancefor most of the studied parameters and showed highest marketable yield ha

(46.23 t
ha
-1
) whereas the lowest (35.82 t ha
-1
) was from control treatment G
).Different treatment combination of mulching and GA
also showed significant
