Two planting methods viz. line and broadcast, five varieties viz. Local,
Barimung 2, Barimung 3, Binamung 2 and Binamung 5 and five sowing dates viz.
February 5, February 20, March 5, March 20 and April 5 were tested to know the
relation between dry matter production and yield of munbean. The highest seed
yield (890 kg ha‾1) was obtained from Barimung 2 and significantly
higher seed yield (870 kg ha‾1) was obtained from February
20 sowing, while March 20 sowing yielded the lowest (593 kg ha‾1).
Barimung 2, Barimung 3 and Binamung 2 performed better in line sowing compared
with broadcast method. Line sowing method was found good when the crop was sown
on February 20. Binamung 5 gave the highest seed yield (1071 kg ha‾1)
when sown on February 20. Binamung 2 gave the highest seed yield (1163 kg ha‾1)
when sown on February 20 in line sowing method. |

An experiment was carried out with 24 brinjal varieties at the Regional Agricultural Research Station, Jamalpur Bangladesh to find the suitable resistant brinjal variety against brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guen. Both in number and weight the brinjal varieties Jumki-1 and Jumki-2 were highly resistant (HR), Islampuri-3, BL-34 and Muktakeshi were fairly resistant (FR), Singnath long and Singnath-4 were tolerant to brinjal shoot and fruit borer. The susceptible varieties were Islampuri-1 and Irribegoon-1. Singnath-3 and Muktakeshi gave the highest yield from three years study and the lowest yield was obtained from Jumki although it was resistant to BSFB. |

This study was conducted during the period of May to December 2001 in four thanas under three southwestern districts of Bangladesh. In the present study structured interview schedule was used as data collection tool. In the surveyed area most of the farmers (45%) having above 4 acres of land and only 23% farmers had 2 acres of land. The major field crop of the study area was rice (aman/boro). Other crops like jute, sesame, groundnut, potato, mustard, vegetables (especially winter vegetables) were also grown in limited areas. About 41% farmers mentioned the salinity intrusion as a major barrier for crop cultivation and 23% farmers mentioned that the increase of salinity in river water is another major cause for salinity increase in cropland. Different farmers described the consequences of salinity in various dimensions, the major effect was the reduction in crop yield (34% farmers). The increasing trend of salinity in southwest region of Bangladesh is reducing the farmers` interest to cultivate various agricultural crops. In the study area, the fruit trees like mango, bettle nut, coconut, sapota, date palm, giant taro, jack fruit, black berry, wax jambu etc are disappearing gradually. The effect of salinity is not only functional on crops but its impact on environment is now well recognized. Declining tree species, reducing soil fertility, increasing disease and insect infestation in field crops, increasing human and animal diseases are the major impact of increasing salinity. Native fish species in open and fresh water bodies are also disappearing gradually. |
