| dc.description.abstract | A field experiment was carried out at the Mithapukur upazila, Rangpur during January,
2020 to April, 2020 to evaluate the performance of chili production under three different
mango variety based agroforestry systems. The experiment was laid out in two factorial
RCBD with 3 (three) replications. Factor A (Three Variety treatment) viz. V1= BARI
Amm-11, V2= BARI-4 and V3= Thai Baromasi and Factor B (Four Fertilizer Applications)
viz. F1= No Fertilizer, F2= Cow-dung, F3= Chemical fertilizer and F4= Chemical fertilizer
+ Cow-dung. Therefore there will be twelve treatment combinations (3 varietal treatment x
4 fertilizers application). The total numbers of experimental plots were 36. The result of
the experiment revealed plant height (00, 15, 30 and 45 days after transplanting: DAT),
number of leaf/plant (00, 15, 30 and 45 DAT), first flowering days after transplanting, first
fruiting days after transplanting, number of fruit/plant, weight of fruit/plant (g), total
Number of fruit/plot, total weight of fruit/plot (kg), fruit length (cm), fruit diameter (cm),
fresh weight/Plant (g), dry weight/Plant (g) and yield (t/ha) of chili significantly varied due
to different varietal treatments and fertilizer applications when cultivated under three
mango based agroforestry systems. In case of main effects of varietal treatments, the
highest chili fruit yield (4.97 t/ha) was recorded from the BARI Amm-4 (V2) treatment and
the lowest fruit yield (3.12 t/ha) was obtained from the Thai Baromasi (V3) based
agroforestry system. In case of main effects of fertilizer applications, the highest chili fruit
yield (4.69 t/ha) was recorded from the plot where chemical fertilizer (F3) was applied and
the lowest fruit yield (3.62 t/ha) was obtained from the plot where no fertilizer (F1) was
applied. In case of interaction effects of the varietal treatments and fertilizer applications
on chilli, the highest chili fruit yield (5.62 t/ha) was observed from V2F3 (BARI Amm-4 +
Chemical fertilizer) combination. From the economic point of view, the highest benefitcost ratio (2.83) was also recorded from the V2F3 treatment combination and the lowest
benefit-cost ratio (1.56) was observed in those plots where chili was grown under Thai
Baromasi mango variety (V3) with cow-dung (F1) application. Not much information is
available on the use of different mango variety as varietal treatment associated with other
crops such as chilli. So, this research findings are helpful for selection mango orchard
according to variety for chilli cultivation as well as others crops.
