Potato is one of the important food crops in Bangladesh. Its demand is increasing day by day. The Tuber Crop Research Centre (TCRC) of BARI released 40 HYV potato varieties and disseminated them in the farmer's fields through different agencies. But most varieties were not adopted well by the farmers due to unknown reasons. Therefore, an attempt was made to assess the level of adoption and profitability of BARI released potato variety at farm level. Data were collected from 150 randomly selected potato farmers from Munshigonj, Bogra and Comilla districts during January-February 2010. The results indicated that 48% potato areas were covered by Diamant variety, 16% by Cardinal, 22% by Granola, and the rest 14% areas were covered by Binella, Asterix, Provento, Felsina, Multa and Hira. The cost of BARI released potato cultivation was Tk 2, 10,629 and Tk 1, 84,135 per hectare on full cost and variable cost basis. The major share of total cost was for seed (42%) followed by fertilizer (21%) and human labour (14%). The average yield of potato was 26 t/ha with gross margin of Tk 1, 51,003 per hectare. The net return of potato cultivation was Tk 1, 24,509 per hectare. The benefit cost ratios were 1.59 and 1.82 on full cost and variable cost basis. Human labour, land preparation, seed, and irrigation had positive and significant effect on potato production. Nonavailability of HYV seed at proper time, lack of technical knowledge, high price of seed and fertilizer, infestation of insect and diseases, and lack of storage facilities were the major problems of potato production.

The socio-economic information on variety development and abiotic stresses of potato cultivation at farm level are scarce in Bangladesh. Therefore, an attempt was made to assess farmers' perceptions about variety development and different abiotic stresses on potato cultivation. Primary data were collected from 240 potato farmers of Bogra and Chittagong district. The study revealed that Granula, Cardinal, and Lalpakri were the most preferred potato varieties in Bogra, while Diamant and Dohazari were the dominant varieties in Chittagong. Most farmers (70.87%) believe that the current potato yield (21.5-22.67 t/ha) can be further increased through introducing new HYVs. Drought and heat were two important limiting factors towards achieving the higher levels of potato yield. High yielding ability was considered as the most desirable varietal character and this was opined by almost 92.1% respondents, followed by drought resistant (61.13%), proper late blight control (58.75%), availability of adequate fund (57.77%), heat tolerant (53.60%), early maturity (61.5%), and good demand (44.5%) for HYV potatoes, whereas good test (81.7%), higher price (69.6%) and good storability (65.2%) were reported for local varieties. Low yield, susceptible to diseases, late maturity and low demand were the reasons for abandoning some potato varieties in the past. Dohazari variety for Chittagong and Lalpakri for Bogra have higher levels of tolerance against abiotic stresses. Finally, early maturity followed by drought tolerance, heat tolerance, and salinity tolerance were important attributes farmers wanted in new potato varieties.

The aims of this study were to determine the kinetics of dehydration of high yielding potato variety (Diamont), to investigate the various process parameters influencing mechanical drying of potatoes and to develop baked product from the dehydrated potato. From the developed equation it was found that the diffusion co-efficient increased with the increase in temperature. The exponential relationship between diffusion co-efficient (D e ) versus inverse absolute temperature (T abs -1 ), activation energy (E a ) for diffusion of water HYV potato was found to be 7.98 Kcal/gm-mole. The influence of loading density as well as thickness of the product on drying rate were determined and the power law equations which described the relationship between drying rate constant and thickness gave an n-value of 0.4586 for HYV of potato. Organoleptic taste tests demonstrated that among biscuits made of various proportion of potato flour and wheat flour, the results of test panel showed that biscuit made of equal proportion (1:1) of potato flour and wheat flour secured the highest score (8.0). All the other samples of each type of product were also accepted by the panelists either as "like moderately" or "like slightly".
