  The performance of blackgram (Vigna mungo L.) under various levels of nitrogen was evaluated at the Bangbandhu Sheikh Mujibur Rahman Agricultural University during March to June 2002. Two varieties of blackgram-BARI mash-3 and BINA mash-1 and six levels of nitrogen-0, 20, 40, 60, 80 and 100 kg N ha-1 were the treatment variables. Dry matter accumulation in different organs of plant was maximum with 80 kg N ha-1. The dry matter accumulation in different vegetative organs continued to increase until pod filling stage and then declined gradually. Contrary, the dry matter accumulation in reproductive organ increased up to maturity. Light Transmission Ratio (LTR) was decreased while Light Interception (LI) increased with the increasing level of nitrogen as well as with the plant ontogeny.

  This study was conducted to evaluate the performance of blackgram (Vigna mungo L) under various levels of nitrogen at the Agronomy Research Site of Bangabandhu Sheikh Mujibur Rahman Agricultural University during March to June 2002. Two varieties of blackgram- BARI mash 3 and BINA mash 1 and six levels of nitrogen viz. 0, 20, 40, 60, 80 and 100 kg N ha-1 were the treatment variables. The experiment was laid out in a RCB Design with three replications. A best-fit positive linear relationship existed between leaf chlorophyll and leaf nitrogen content with different nitrogen levels. Unexpectedly the N, P and K accumulation in the two varieties was not affected significantly. However, there was an increasing tendency of total uptake of these elements in both the varieties. N, P and K uptake increased up to 60 kg N ha-1 then decreased with the increasing nitrogen levels. Among the varieties BARI mash 3 showed better performance than BINA mash 1 for most of the parameters.

  This study examines the levels, trends and differentials of age at first marriage and also to identify the various demographic, social and economic factors influencing on age at first marriage of rural woman in Bangladesh. In this analysis, the overall mean age at first` marriage of rural Bangladeshi woman is found to be only 14.76 years. Marriage cohort analysis of the respondents suggests that mean age at first marriage among most recent cohort is about 1.22 years higher compared to earlier cohort. Independence χ2-test statistic and logistic regression analysis reveal that respondent`s education, access to mass media, religion, husband`s education, childhood place of residence and region have highly significant impact on age at first marriage, whereas husband`s occupation and respondent`s working status have little bit significant effect. Path analysis technique also reveals that all of the direct effects are significantly influenced on age at marriage and the indirect effects are appreciably prejudiced in the same.
