Response of different organic nutrient management schedules on productivity, head quality, nutrient uptake and economics of organic cabbage

Abstract

Field experiments were conducted to explore the possibility
of improving the productivity of organic cabbage by
evaluating the response of different organic nutrient
schedules comprising of enriched farmyard manure,
vermicompost and poultry manure as basal and top-dressing
during winter season of 2017-18 and 2018-19 at UBKV,
Pundibari, West Bengal. The experiment consisted of 8
treatment combinations and laid out in randomized block
design with three replications. The results revealed that the
use of Azophos biofertilizer enriched poultry manure (5t/ha)
as basal along with 2-times top dressing (1 t/ha) at 30 and 45
days after transplanting significantly increased the head
yield (1.64 kg/plant and 42.76 t/ha) along with superior head
quality in terms of maximum vitamin A (126.01 IU/100 g),
vitamin C (44.02 mg/100 g) and TSS (6.50 oBrix) of organic
cabbage. The treatment combination comprised of Azophos
biofertilizer enriched vermicompost (2.5 t/ha) and enriched
poultry manure (2.5 t/ha) as basal along with 2 times top
dressing of both (0.5 t/ha) at 30 and 45 days after
transplanting proved to be the second-best option for
organic cabbage cultivation of the region.
