Abstract/ Executive Summary:

Three orange sweet potato (OSP) varieties BARI SP-4, BARI SP-7 and BARI SP-8 were introduced in 20m² area within homestead vegetable production system of poor farming households in six agroecological regions of Bangladesh during 2011-12 and 2012-13. Data on different aspects of the study were collected from 196 randomly selected households. The average productions of roots and leaves of OSP per household were 33.65 and 12.11kg respectively from 20m2 of land during 2011- 12. However, during 2012-13 season average production of roots and leaves were 36.24 and 12.36kg respectively from same area of land. Of the average total production of roots and fresh leaves of 47.15kg per year, 34.66kg was consumed at household level, 6.84kg was sold and 5.89kg was gifted to neighbours and relatives. The average gross return from cultivation of OSP at household level from 20m2 of land per year was BDT* 845.00. Organoleptic test revealed that the acceptability of OSP for consumption as boiled roots and leaves varied slightly from region to region and variety to variety.

Objectives:

Considering the above, the present study was undertaken by introducing three OSP varieties BARI SP-04, SP-07 and SP-08 in homestead vegetable production system by involving women members of the small and marginal farming households to assess its impact on production and consumption in six different regions of Bangladesh.

Methodology:

The study was conducted in 6 (six) agro-ecological regions of Bangladesh namely Barisal, Faridpur, Jessore, Khulna, Mymensingh and Rangpur under the USAID funded Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD) project from November, 2011 to April, 2013. The Bangladesh Agricultural Research Institute (BARI) released OSP varieties namely BARI SP-04, BARI SP07 and BARI SP-08 were introduced in the homestead vegetable production system. Selected women of the marginal and small farming households were provided training and supported by OSP vines to cultivate in small pieces of homestead land (20m2 ) over two cultivation seasons of 2011-12 and 2012-13. Crop management practices of OSP including use of organic and inorganic fertilizers were followed as per the recommendation of Bhuiyan et al. (2008).

Land selection and preparation Well-drained, sandy loam and sunny place of homestead was selected for OSP production. Deep ploughed with basal dose of fertilizers at the rate of organic matter: 4-5 kg, TSP: 300g, and 50% of total required urea:150g, and MOP: 180g per 20m².

Cutting preparation and plantation Insect and disease free stems with 3-4 nodes were selected. The length of cutting was 25-30cm, except top leaves, all leaves were removed. Cuttings were horizontally planted and 2-3 nodes were placed inside the soil and 1-2 nodes were above the soil. A total of 120 OSP cuttings were plated in 20m2 land following an approximate planting spacing of row to row 60cm and plant to plant 30cm.

Intercultural operations Regular irrigations were provided at 30, 60 and 90 days after planting (DAP), dependent on raining. Earthing up of soil was done and rest of the urea and MOP was applied on 60 DAP in between two line of vines. Weeding was done when necessary and vines were lifted at 60 DAP, later on continued once in a month throughout the growing period.

Harvesting Leaves harvesting started after 80 days of plantation and continued up-to root harvesting. Roots were harvested at 130 days after vine plantation through uprooting by spade. Data were collected from randomly selected 196 project households (HHs) through face to face personal interview using structured questionnaires on performance of the three OSP varieties in homestead production system during 2011-12 and 2012-13. Also data in respect of crop management and farmers’ behaviour for utilization and acceptance of OSP were also collected from the sample HHs. The collected data where necessary were analyzed using a Microsoft Excel Spread sheet.

Achievement/Findings:

Results of the present study revealed that three OSP varieties viz. BARI OSP-04, BARI OSP-07 and BARI OSP-08 released by Bangladesh Agricultural Research Institute (BARI) can be successfully cultivated in homestead vegetable production system in small area of land (20m²) with reasonable yield by the marginal and small women farmers as one of the means of constant supply of nutritious food and vitamin-A to the household members round the year with reasonable household income. Consumers’ preference and comparative advantage responses indicate that urgent attention is needed by the government agencies and private sectors for expansion of the cultivation of OSP varieties at homestead level by the marginal and small women farmers to combat the chronic vitamin-A and other micronutrient deficiency. Also other varieties like BARI SP-12 and SP-13 with high vitamin-A content may be tried for cultivation in homestead level.
