The study was conducted in three districts namely Narshingdi, Jessore and Bogra to assess the postharvest losses of brinjal. Multistage sampling technique has been used for selection of 90 brinjal growers and intermediaries, out of which 15 farmers and 15 intermediaries from each district selected randomly. Both descriptive and inferential statistics were used to calculate the postharvest losses of brinjal at different stages and determine the factors responsible of postharvest losses of brinjal at farmer level; a multiple linear regression model was carried. Total postharvest losses of brinjal were estimated by taking total losses at farmer, Aratdar, Bepari and retail level. A total postharvest loss of brinjal was 23.38%. Highest loss was estimated that 12.51% at the grower level. Among different intermediaries post harvest loss of brinjal was highest at retail level (5.96%) than Aratdar level losses (2.35%) and Bepari level losses (2.65%). Farming experience, sale price, transportation had negative and total production and weather had positive and significant relationship with the total postharvest loss of vegetable. Absence of postharvest treatments, low market price, lack of available storage facilities, and poor and costly transportation were the major problems at farm and intermediaries level. Proper storage facilities, easy transportation, applied scientific method of harvesting and fair price policy suggested by the study to minimize the postharvest loss.
The study was conducted in two districts namely Sylhet and Narsingdi to investigate the production technology of Jara and Colombo lemon growers, estimate profitability and identify the constraints of Jara and Colombo lemon. A total sample of 120 farmers taking 60 for Jara lemon from Sylhet and 60 for Colombo lemon from Narsingdi was selected randomly for the study. Data were collected through face to face interview method by using structured questionnaire during April-May, 2016. Cost return analysis revealed that Jara and Colombo lemon cultivation were profitable in the study areas. Jara lemon cultivation highest cost was estimated Tk. 413575/ha in (11-15) th year garden and lowest cost was Tk. 365777/ha in 2 nd year garden. Gross return was highest in 5 th year garden (Tk.1995750/ha) and lowest Tk. 975600/ha in (11)(12)(13)(14)(15) th year garden. The benefit cost ratio at 6.5% rate of interest was 2.85and IRR 78%. Colombo lemon cultivation highest cost was estimated Tk. 316505/ha in 4 th year garden and lowest cost was Tk. 257543/ha in (11)(12)(13)(14)(15) th year garden. Gross return was highest Tk. 841522 in 5 th year garden and lowest Tk. 413616/ha in (11-15) th year garden. The benefit cost ratio at 6.5% rate of interest was 1.81 and IRR 65%. Lack of improved production technology, poor quality saplings, insect/pest infestation, adulteration of fertilizer and insecticides and less number of export buyers were found major constraints both Jara and Colombo lemon production.
The study was conducted in three districts namely Panchagarh, Bandarban and Moulovibazar to know the production technology of mandarin cultivation and to estimate profitability and identify the constraints of mandarin cultivation. A total of 99 farmers taking 33 from each district were selected randomly. Data were collected through a pre-tested schedule during January-March, 2016. Cost and return analysis revealed that mandarin cultivation was profitable in the study areas. The highest cost was estimated Tk. 215293/ha in 16-20 th year garden and lowest cost Tk. 119993/ha in 2-4 th year garden. Highest yield was found 16020 kg/ha at 11-15 th year garden followed by 13800 kg/ha at 16-20 th year garden and lowest yield 11100 kg/ha at 5-10 th year garden. The highest gross return was found in Tk. 640800/ha at 11-15 th year garden and lowest return was Tk. 444000 at 5-10 th year garden. The highest amount of net return was found in the Tk. 435859/ha at 11-15 th year garden and lowest return was Tk. 235286 in 5-10 th year garden. The benefit cost ratio at 12% rate of interest was 1.68, NPV Tk. 920401 and IRR 30%. Sensitivity analysis implied that mandarin cultivation is profitable. Scarcity of irrigation in hill areas, acute problem of insect/pest infestation, lack of improved production technology, poor quality and scarcity of seedlings/saplings, lack of capital for initial investment and low yield of different varieties were found major constraints for mandarin cultivation in the study areas.
This study was conducted to analyse profitability of HYV Boro during the 2016 Boro season. BR-29 variety was selected for analysis as this variety is dominated among all Boro varieties in the study area. A total of 75 farmers were randomly selected from seven villages of Islampur Upazilla under Jamalpur district that produced BR-29 boro variety. Primary data collection was done from the randomly selected farmers. Functional analysis of cost and return were performed in this study. Cobb-Douglas production function was also used to determine the individual input effects on BR-29 production. Human labor, land cultivation, seed, fertilizer, manure, irrigation and pesticides were seven variables used. It was observed from the result that majority of the variables had shown significant impact on BR-29 Boro production value. This study also identified some problems faced by the farmers in producing BR-29 Boro rice. These were low price of output, scarcity and high wage rate of human labour, high irrigation cost, lack of credit facilities etc. Therefore, more research and extension are suggested to solve the farmers’ problems to increase production of Boro rice and to ensure food security in Bangladesh.
The study was conducted in three malta growing districts namely Khagrachori, Pirojpur and Chapai Nawabganj during January-March 2018. An attempt was made to assess the adoption status of BARI Malta-1 (sweet orange), its farm level profitability, problems and the impacts of malta cultivation on the livelihood of farmers. A total of 180 farmers, 60 farmers from each district were randomly selected for this study. The study revealed that 91% farmers adopted BARI Malta-1 in their gardens. Higher yield, profitability, sweetness, and less insect-pests infestations were the major reasons for choosing BARI Malta-1 at farm level. Farmers did not follow the recommended doses of manures and fertilizers due to lack of adequate knowledge on recommended doses. The establishment cost of a malta garden was Tk. 7,02,650 per hectare. The highest yield (19.6 t/ha) and gross return (Tk. 15,68,000/ha) were obtained from 5th to 10th year gardens. The lowest return (Tk. 8,28,160/ha) was reported in the 3rd year garden. Scarcity of saplings, un-attractive colour, and lack of technical know-how were the major problems to BARI Malta-1 cultivation. The study suggested availability of saplings, hands-on training to the farmers, and affordable price of different input for higher adoption of this variety. Bangladesh J. Agril.
