  The study was carried out during aman season in the Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna, Bangladesh to observe the yield performance of aromatic fine rices (Oryza sativa L.) in the medium high land of coastal region. The experiment was laid out in a Randomized Complete Block Design with three popular aromatic rice varieties of Bangladesh namely Begunbitchi, Chinigura-1 and Kalijira and five replications. All the parameters e.g. tiller number per hill, days required for booting, heading and flowering, panicle length, spikelet number per panicle, 1000-grain weight, grain yield and harvest index varied significantly among the varieties. Chinigura-1 produced the highest grain yield (2.47 t ha-1) followed by Kalijira (2.15 t ha-1) and Begunbitchi (0.92 t ha-1). The yield of Chinigura-1 obtained in this study is almost similar to that of national average (2.40 t ha-1). Chinigura-1 may be a potential aromatic rice variety in the coastal medium high lands of Bangladesh.

  A field experiment was conducted to determine the influence of population density and planting configuration on allometric relationships in Mungbean. The experiment was conducted with six levels of population densities (10, 20, 30, 40, 50 and 60 plants m-2) each at three levels of configuration (1:1, 1:2.5 and 1:5 rectangularity). Accumulation and distribution of dry matter to different components of plants were determined. Allometric relationships between stem weight and leaf weight were developed from their respective dry weights. Stem materials per unit leaf weight increased over growth stages. Reproduction enhanced dry matter allocation into stem per unit leaf weight. The magnitude of increase varied greatly with planting density. The ratio of stem weight per leaf weight and leaf weight were linearly correlated. Planting configuration had little effect on the allometric relationship.

  Growth ecology of Pila globosa was studied in the simulated habitat with reference to its natural food habit. Growth rate and obesity index value for the snail population reared on natural aquatic food plants were higher than those, reared on cultivated food, Puni (Basela rubra). For natural food, the minimum and maximum mortality rates at age intervals of 224-238 days and 0-14 days were calculated as 0.00% and 16.00% while, on supplied cultivated vegetable food, (B. rubra) at 252-266 days and 0-14 days age intervals, were obtained as 0.00% and 18.00% respectively. The life table was constructed on 266 days study of snails, reared on both types of food plants. The findings indicate the possibility of snail culture on large scale, in simulated habitats provided with physico-chemical parameters, like water temperature, pH, turbidity and dissolve oxygen of water, strictly maintained.

  A field experiment was conducted in a coastal low land to observe the performance of three aromatic rice varieties namely Begunbitchi, Chinigura-1 and Kalijira at the Field Laboratory of Agrotechnology Discipline of Khulna University during aman season 2003. The experiment was laid out in a Randomized Complete Block Design with five replications. Thirty-three days aged seedlings were transplanted with 3 seedlings/hill. Fertilizers were applied at the rate of 50, 35 and 88 kg N, P and K h-1, respectively. The yield and yield components varied significantly among the varieties except 1000-grain weight. Chinigura-I gave the highest grain yield (2.30 t ha-1) followed by Kalijira (2.08 t ha-1) and Begunbitchi (0.85 t ha-1). The highest grain yield of Chinigura-I was obtained due to its longer panicle, number of spikelets per panicle and higher harvest index. The yield of Chinigura-I in the coastal low land was almost similar to that of national average yield in Bangladesh for this variety (2.40 t ha-1).

  A field experiment was conducted to determine the influence of population density and planting configuration on dry matter allocation and yield performance of mungbean. The experiment was conducted with six levels of population densities (10, 20, 30, 40, 50 and 60 plants m-2) each at three levels of configuration (1:1, 1:2.5 and 1:5 rectangularity). Accumulation and distribution of dry matter to different components of plants were determined. At maturity, grain yield and yield contributing characters were recorded. Population density decreased plant size, but the effect was offset when converted to per unit area basis. Seed yield per plant decreased progressively with the increase in planting density. Significant variation in the number of pods per plant and seeds per pod due to differences in population density caused the variation in seed yield. Planting at higher rectangularity (1:5) out yielded other planting configurations. Planting density and configuration caused similar effect on harvest index.

  Experiments were conducted to evaluate the dietary effects of molluscan flesh (Pila globosa, Bellamya bengalensis and Lamellidens marginalis) fresh, boiled and endogenous products, pellets (40% rice bran, 30% wheat bran, 20% mustard oil cake and 10% prawn head powder) on growth, survival and production rate of Penaeus monodon under traditional upgraded extensive method. The maximum survival rate, individual increment in length and weight, production rate and profit were 80.4%, 1.71 mm and 0.57 gm day-1, 989.88 kg ha-1 and 115.58%, respectively from the culture supplemented with fresh molluscan flesh and pellet food in equal proportions. Fresh molluscan flesh with pellets in equal proportions was the most effective feed followed by fresh molluscan flesh.
