Abstract:
The experiment was conducted at the Central Farm of Sher-e-Bangla Agricultural
University (SAU), Sher-e-Bangla Nagar, Dhaka-1207, Bangladesh during the period
from November, 2019 to April, 2020 to investigate the effect of bio-fertilizer mixed
nutrient sources on the quality seed production of radish varieties. The seeds of BARI
mula-1, BARI mula-2 and BARI mula-4 were collected from the Bangladesh
Agricultural Research Institute, Gazipur, Dhaka. This experiment was conducted with
two factors: Factor-A (Varieties)- (i) V

. The two
factors experiment was laid out in a Randomized Complete Block Design (RCBD) with
three replications. BARI recommended the following doses of manures and fertilizer:
Cowdung-25 kg/ha, Urea-300 kg/ha, TSP-200 kg/ha, MP-200 kg/ha, Gypsum-50 kg/ha
and Bio-fertilizer- 4kg/ha were applied. Seeds were sown on 15 November and distance
to be maintained 30cmX30cm, respectively. In case of different variety, maximum
number of siliqua per inflorescence (132.42), number of seeds per siliqua (6.58), seed
yield per hectare (1.38 t) were observed from V
3
treatment and minimum number of
siliqua per inflorescence (67.50), number of seeds per siliqua (3.62) and seed yield per
hectare (0.75 t) were obtained from V
2
treatment. For different nutrients, maximum
number of siliqua per inflorescence (125.67), number of seeds per siliqua (6.20) and
seed yield per hectare (1.33 t) were observed from N
1
treatment and minimum number
of siliqua per inflorescence( 93.11), number of seeds per siliqua (4.97) and seed yield
per hectare (0.97 t) were observed from N
2
treatment. Due to combined effect, at
harvest the maximum number of siliqua per per inflorescence (154.33), number of seeds
per siliqua (7.27) and seed weight per hectare (1.59t) were obtained from V
3
treatment combination and the minimum number of siliqua per inflorescence (61.0),
number of seeds per siliqua (3.27) and seed weight per hectare (0.63 t) were produced
from V

N

treatment combination. So, the V

treatment combination appeared to be
the best for achieving the higher growth and seed yield of radish.
