  A comparative study on productive and reproductive performance of crossbred and indigenous cows under the small holder dairying condition was conducted in Gaibandha district of Bangladesh. A sample of 96 dairy cows were selected randomly; of which 49 were crossbred cows and the other 47 were indigenous dairy cows from 50 small dairy farms. The productive performance (milk yield and lactation period) of crossbred cows were significantly (p<0.01) higher than the indigenous dairy cows. Post partum heat period, calving to first service and dry period of the indigenous cows were lower (but not significantly) than crossbred cows. But service per conception and calving interval of indigenous cows were significantly (p<0.01) lower than the crossbred cows. The cost benefit ratio of raising crossbred and indigenous dairy cows were 1:1.13 and 1:1.02, respectively. Although, reproductive performance of crossbred cows were better than indigenous cows but considering the other traits it may be concluded that the raising of crossbred cows were more economic than the raising of indigenous dairy cows.

  Field experiments were conducted with potato in a silt-loam soil of the Bangladesh Institute of Nuclear Agriculture sub-station farm, Rangpur, Bangladesh during the winter season (November-March) of 1993-94 and 1994-95 to study its yield response due to deficit irrigation imposed at different growth stages. Nine different irrigation treatments were followed with the combinations of four different growth stages (i.e. stolonization, tuberization, bulking and tuber enlargement) allowing water stress at single to all stages. Irrigation showed significant effect on the yield of potato in 1993-94. But there was no significant yield difference due to different levels of watering and stresses of potato during 1994-95. Highest potato yields of 21.0 t/ha and 25.97 t/ha were obtained in 1993-94 and 1994-1995 by applying a total of 7.38 cm and 7.06 cm irrigation water, respectively, at stolonization, tuberization and bulking stages. It was also found that water stress at the early two stages (I. e. stolonization and tuberization) showed sharp negative response to the yield of potato compared with bulking and tuber enlargement stages. Thus, the experimental results revealed that irrigation at tuber enlargement stage could be withheld without significant yield decrease in potato.

  The study was undertaken to compare the productive and reproductive performance of crossbred and indigenous cows as well as the relative profitability of crossbred and indigenous cows under small holder dairy farming. From this study it was seen that the milk yield and lactation period were 4.10 litre/day and 266 day respectively in crossbred and 2.28 litre/day and 220 days respectively in indigenous cows. The variation in the length of post partum heat period and calving to first services were not statistically significant between the crossbred and indigenous cows. The length of calving interval were statistically significant be to crossbred and indigenous cows. Among the costs (Feed cost, housing cost labor cost, housing cost labor cost, treatment cost and A.I. charge), except the housing costs all costs were statistically significant (p<0.01) between the crossbred and indigenous cows. The returns (sale proceeds of milk, value of cowdung, value of calf and price of empty gunny bags) of the crossbreds were higher than the indigenous cows.
