    GROWTH AND YIELD OF T. AMAN RICE AS AFFECTED BY VARIETY AND SEEDLING NUMBER
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2011-07) Mahmud, J. A.; Shamsuzzaman, A. M. M.; Haue, M. M.; Islam, M. M.
    A field experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during July to December 20 I 0 to find out the effect of I, 2 or 3 seedling(s) per hill on growth, yield and yield components of a modern inbred (BRRI dhan49) and four hybrid (BRRI hybrid dhan2, Heera2, Tia and Aloron) transplant Aman rice varieties. The experiment was laid out in randomized complete block design with four replications. Results showed that rice cultivars differed significantly in some characters at different growth stages, such as, tillers number, total dry matter weight, unfilled grain, grain filling percentage and insignificantly in some characters at different growth stage, such as, chlorophyll content, yield etc due to different seedling densities per hill. Numerically the higher grain yield was attributed mainly to the number of effective tillers per hill, filled grains per panicle and 1000-grain weight. Remarkable grain and straw yield were found from the interaction of.BRRI dhan49 planted I seedling and 3 seedlings per hill respectively. Among the hybrid rice varieties, the maximum grain yield was observed from the combination of BRRl hybrid dhan2 with I seedling per hill (V2Sd.

    STUDY ON PLANT DIVERSITY IN SHER-E-BANGLA AGRICULTURAL UNIVERSITY CAMPUS
    (Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2011) Sultana, N.; Mahmud, J. A.; Solaiman, A. H. M.
    A survey carried out to assess the plant diversity and conservation of plant genetic resources in Sher-e-Bangia Agricultural University, Dhaka. The data were collected during May 2011 to April 2012. The total number of plants belongs to 150 families under 244 genera and 319 species respectively. Out of all plant species 19 timber species (including 13 genera and II families), 42 fruit plant species (28 genera 19 families), 61 medicinal plant species (55 genera and 34 families), 78 flower plant species (51 genera 27 families), 40 ornamental plant species (33 genera and 24 families), 41 vegetable plant species (30 genera 16 families), 13 spices plant species (II genera 8 families), 6 fodder plant species (6 genera and 5 families), 5 bamboo plant species (2 genera I families), 3 ficus plant species (l genus and I family), 2 fibre plant species (2 genus and 2 family), to palm plants (lO genera and 2 families), 2 rubber plants (2 genera and I families) have been documented. All the species, 133 were found abundantly, while 73, 31, and 85 plants species respectively were recorded frequently, occasionally and rarely in the studied area. Out of total species 119 are trees, 75 shrubs, 85 herbs, 35 climbers and 5 woody grasses in habit. Fabaceae is the largest family having many plant species. A record on the plant genetic resources of Sher-e-Bangia Agricultural University have also been developed with the taxonomic ways of resources. Huge number of plant species are found as rare and threatened. Some suggestions have been made to enhance the co
