| dc.description | Agroforestry is an integrated approach of using the interactive benefits
from combining trees and shrubs with crops and/or livestock. It
combines agricultural and forestry technologies to create more diverse,
productive, profitable, healthy and sustainable land-use systems
(USDA National Agroforestry Center). According to the World
Agroforestry Centre, Agroforestry is a collective name for land use
systems and practices in which woody perennials are deliberately
integrated with crops and/or animals on the same land management
unit. The integration can be either in a spatial mixture or in a temporal
sequence. There are normally both ecological and economic
interactions between woody and non-woody components in
agroforestry. In agroforestry systems, trees or shrubs are intentionally
used within agricultural systems, or non-timber forest products are
cultured in forest settings. Knowledge, careful selection of species and
good management of trees and crops are needed to optimize the
production and positive effects within the system and to minimize
negative competitive effects. | en_US |
| dc.description.abstract | An experiment was conducted at the Agroforestry Research Farm, Hajee Mohammad
Danesh Science and Technology University, Dinajpur during May to July 2010 to
investigate the performance of napier fodder varieties undere mango (Mangifera
indica) orchard. The experiment was consisted of 2 factors RCBD with 3 (three)
replications. Among the two factors, one factor A was two production systems: S, =
mango + napier and S, = napier (sole crop); another factor B was three napier
varieties: V; = BARI Napier- 1 (Bazra), V2 = BARI Napier-2 (Arusha) and V3 =
BARI Napier-3 (Hybrid). The experimental results revealed that the main effect of
variety on growth, yield contributing characters and yield of napier fodder were
significantly varied from each other. The highest yield (4.97, 10.93 and 5.13 tha” at
1‘, 2™ and 3™ harvest, respectively) was recorded in variety Bazra whereas the lowest
yield (2.14, 5.47 and 2.85 tha’ at 1‘, 2" and 3™ harvest, respectively) was recorded in
variety Hybrid. Again, the yield of napier fodder were significantly influenced by the
main effect of different production systems. The highest yield (10.01, 21.56 and
10.64tha” at 1‘, 2™ and 3" harvest, respectively) of napier was recorded under mango
based AGF system. Significantly, the lowest yield (8.28, 19.54 and 8.71 tha” at 1°, 2"
and 3™ harvest, respectively) was recorded in open condition i.e. sole cropping.
Moreover, the interaction effect of different napier fodder variety and production
system on the yield of napier was found significantly different at different harvest.
The highest yield (6.53, 12.13 and 5.60 tha” at 1%, 2" and 3™ harvest, respectively)
was recorded in mango based AGF system with Bazra variety and the lowest yield
(1.88, 5.60 and 2.85 tha’! at 1", 2™ and 3™ harvest, respectively) was found in mango
based AGF system with Hybrid variety. Therefore, the suitability of napier cultivation
under mango based AGF system may be ranked as Bazra > Arusha > Hybrid variety.
Again, in case of economical analysis the BCR of mango based AGF system (3.91)
was superior over sole cropping (3.28). So, from the findings it may be concluded that
the cultivation of napier in the floor of mango orchard ensures higher revenue to the
farmers compared to its sole cropping. | en_US |
