| dc.description.abstract | A scientific research experiment in Panchbibi upazila under Joypurhat district during July to
December 2017 was conducted to evaluate the identification and economic evaluation of
agroforestry systems of homestead, cropland and orchard. Extensive field survey and field
measurements were done in 20 villages under 4 unions out of 8 unions of the upazila. The
studied unions were Balighata, Bagjana, Dharanji and Aymarasulpur. A multistage random
sampling procedure was followed in this research experiment. A pre-structured questionnaire
was used for collecting the data. A total of 57 agroforestry practices including 20 homesteads, 17
orchards and 20 croplands were evaluated. Normality test of income and cost data was done by
Kolmogorov-Smirnov Test. Three years costs and income data were collected from the field
survey. Linear regression equation was obtained by using trend line in MS Excel to forecast
seven years of income and cost data of different agroforestry systems. Benefit-cost ratio (BCR)
was determined upto ten years by using actual and forecasted income and cost data of three
agroforestry systems. Results of the cost analysis showed that though significantly maximum
cost was in orchard agroforestry system (Tk. 308083 per ha.) followed by cropland (Tk. 144886
per ha.) and minimum in homestead agroforestry system (Tk. 31297 per ha.) in the 1st year. Cost
decreasing trend was recorded in the successive years in all the systems. Forecasted data showed
that after 5 years; all costs were zero in homestead, while in orchard the same was zero after 5.5
years but there was some costs all the time during ten years period. Income analysis of
agroforestry showed that though initial income was significantly higher in orchard agroforestry
followed by cropland and homestead and lowest income was in homestead agroforestry system
but after 10 years highest income was found in orchard agroforestry system (Tk. 901561 per ha.)
and lowest income was found in cropland agroforestry system and after nine years the income of
cropland was zero. The overall net income was highest in orchard (Tk.311514) and lowest was in
homestead (Tk.23511). The net income indicated that orchard agroforestry system is financially
more profitable than cropland and homestead agroforestry systems, while the benefit-cost ratio
(BCR) is higher in homestead (15.97) and lower in cropland agroforestry system (1.27). The
study revealed that within the agroforestry systems (homestead, cropland and orchard) of
Panchbibi upazila 11 agroforestry practices were recorded. The practices were mixed home
garden, Eucalyptus, Mango+Litchi, Mango, Ghoraneem, Litchi, Eucalyptus+Mahogoni,
Eucalyptus+Akashmoni, Eucalyptus, Mahogony, Mango+Mahogony, Jhingon+Betel leaf and
with or without different combinations of seasonal crops. Among 57 practices, mixed home
garden occupied the maximum number (29) and lowest number(1) was Mango+ Litchi,
Mango+Mahogoni, Jhingon+betel leaf and Ghoraneem .The findings suggest that orchard as
well as homestead agroforestry systems are economically more profitable than cropland
agroforestry system of Panchbibi upazila. Within the 11 practices eucalyptus+mahogany based
agroforestry practices is profitable in Panchbibi upazila. So, orchard of Panchbibi can be
improved by proper management practices, co-operative and more applying scientific
knowledge. Therefore, more emphasis should given in establishing orchard agroforestry to
improve their economical status in Panchbibi upazila | en_US |
