| dc.description.abstract | A field experiment was carried out at the Agroforestry and Environment
Research Farm, Hajee Mohammad Danesh Science and Technology
University (HSTU), Dinajpur, during October, 2016 to March, 2017 to
evaluate the varietal performance of chili and organic chili production
under mango based agroforestry system. The experiment was conducted
in the mango orchard where the tree saplings were planted at the
spacing 6 m × 6 m in the year 2006. The experiment was laid out in two
factorial RCBD with 3 (three) replications. Factor A (three chili varieties)
viz. V1 = Hybrid, V2 = Kajli and V3 = Shity. On the other hand, factor B
was four types of fertilizer & manure applications viz. no fertilizer (F1),
cow-dung (F2), poultry manure (F3) and chemical fertilizer (F4). There
were twelve treatment combinations and there were: V1F1 (Hybrid + no
fertilizer), V1F2 (Hybrid + cowdung), V1F3 (Hybrid + poultry), V1F4
(Hybrid + chemical fertilizer), V2F1 (Kajli + no fertilizer), V2F2 (Kajli +
cowdung), V2F3 (Kajli + poultry), V2F4 (Kajli + chemical fertilizer), V3F1
(Shity + no fertilizer), V3F2 (Shity + cow dung), V3F3 (Shity + poultry) and
V3F4 (Shity + chemical fertilizer). The result of the experiment revealed
that plant height (30, 45, 60, 75 and 90 DAT), leaf length (30, 45, 60, 75
and 90 DAT), leaf breadth (30, 45, 60, 75 and 90 DAT), number of
leaf/plant (30, 45, 60, 75 and 90 DAT), number of shoot/plant (45, 60, 75
and 90 DAT), number of fruit/plant, weight of fruit/plant (g), total number
of fruit/plot, total weight of fruit/plot (kg), fruit length (cm), fruit breadth
(cm), fruit number yield (t/ha), % dry weight of fruit and yield (ton/ha) of
chili were significantly varied due to different chili variety and fertilizer
and manure application. In case of main effects of variety, the highest
fruit yield (12.99 ton/ha) was recorded from the variety Kajli (V2). On the
other hand, lowest fruit yield (5.49 ton/ha) was obtained from the variety
Shity (V3). In case of main effects of fertilizer and manure application, the
highest fruit yield (12.16 ton/ha) was recorded from the plot where
chemical fertilizer (F4) was applied. On the other hand, lowest fruit yield
(6.949 ton/ha) was obtained from the plot where no fertilizer (F1) was
used. In case of interaction effects of the chili variety and fertilizer and
manure applications, the maximum yield (17.09 ton/ha) was obtained
from the treatment combination V2F4 (Kajli + chemical fertilizer) and
minimum yield (3.54 ton/ha) was obtained from the treatment
combination V3F1 (Shity + no fertilizer). Again, from the economic
analysis, the highest BCR (3.42) was recorded from the treatment combination of Kajli (V2) + chemical fertilizer (F4). On the other hand, the
lowest BCR (1.80) was recorded from the treatment combination of
Shity(V3) + no fertilizer (F1) was applied. Moreover, the varietal
performance of different chili varieties under mango based agroforestry
system ranked as Kajli>Hybrid>Shity and out of the four fertilizer and
manure applications chemical fertilizer would be the best fertilizer
treatment. Though organic manure (Poultry manure) was given less
production than chemical fertilizer, but it is ecofriendly and safe. In
safety point of view, organic manure is the best for chili production. | en_US |
