| dc.description.abstract | A field experiment was conducted in the Agroforestry and Environment
Research Field, Hajee Mohammad Danesh Science and Technology
University, Dinajpur, during October 2016 to February 2017 to evaluate
the varietal performance of cauliflower influenced by different fertilizer
and manure applications under mango based agroforestry system. The
experiment was laid out in two factors Randomized Complete Block
Design (RCBD) with three replications. Three cauliflower varieties viz.
Aksel (V1), Snowball-1 (V2) and Maghi (V3) were considered as factor A;
while fertilizer and manure applications viz. no fertilizer (F1), chemical
fertilizer (F2), cowdung (F3) and poultry (F4) were factor B. The data were
collected at 15, 30, 45 and 60 DAT (days after transplanting) for plant
height (cm), number of leaves per plant,outer leaf length (cm),outer leaf
width (cm), curd size (cm2), yield of curd (t ha-1). The results revealed
that fertilizer and manure applications had significant effect on the
growth, yield contributing characters and yield of different cauliflower
varieties.In case of main varietal effects, the highestand the lowest curd
yield (30.78t ha-1) and (20.00t ha-1) were recorded in Snowball-1andAksel
respectively. Again, in case of main effect of fertilizer and manure
applications, the highest curd yield (36.47t ha-1) was found in chemical
fertilizer application and the lowest yield (20.32 t ha-1) was found in no
fertilizer application. Furthermore in case of the interaction effect of
variety and fertilizer and manure applications, the maximumcurd yield
(32.27 t ha-1) of cauliflower was recorded in Snowball-1varietywith
chemical fertilizer application and the minimum yield (19.52 t ha-1) was
recorded invariety Aksel with no fertilizer application. On the other hand,
from the economic analysis, it was observed that the highest BCR (3.17)
was found in the plot where Snowball-1 variety was cultivated with
chemical fertilizerwhereas the lowest BCR (2.38) was received where
variety Aksel was grown without fertilizer. Finally,it may be concluded that monitoring the yield and economic return among the three
cauliflower varieties and different fertilizer and manure applications, the
best performance according to yield were Snowball-1>Maghi>Aksel and
chemical fertilizer>cowdung>poultry>no fertilizer under mango based
agroforestry system. Though chemical fertilizer application gave
maximum economic return, cauliflower variety Snowball-1 using
cowdung may be a viable option for safe cauliflower production by
considering the environmental benefit. | en_US |
