parameters of rice varieties except harvest index also differed significantly with the
application of phosphorus fertilizer. An application of 72 kg P205 hn' showed to

in respect of yield and yield attributes of rice was observed. Plants grown at any varieties

SEMESTER:JULY-DECEMBER, 2009The experiment was conducted at the experimental field of Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh during the period from June to
November, 2009 to find out the most effective management practice(s) among
Trichogramma evanescens egg parasitoid @ 0.25 gm and 0.50 gm plot-1, Bacillus
thuriengiensis bacterium suspension @ 0.1% and 0.2%, SafeClean @ 0.05%,
SafeMax @ 0.05%, Neem oil @ 0.3% and chemical insecticide Furadan 5G @ 6 gm
plot-1 for the eco-friendly management of rice stem borer on hybrid rice (Hira-2). The
experiment was laid out in Randomized Complete Block Design (RCBD) with three
replications. Considering the dead heart and white head infestation, among the
treatments chemical insecticide Furadan 5G (T8) performed as the most effective
practice in reducing the dead heart (81.47%) and white head (91.44%) infestation over
control followed by Trichogramma egg parasitoid @ 0.50% (T2) treatment (73.64%
and 82.34%, respectively). T8also gave the maximum yield contribution characters of
the rice plants as well as produced the highest grain yield (7.67 ton ha-1) followed by
T2 (7.23 ton ha-1). Economically the most effective treatment was T2, through which
the highest benefit cost ratio (5.04) was achieved as compared with other treatments
including Furadan 5G (3.80). Considering the ecological point of view, the T2
comprising Trichogramma evanescens egg parasitoid @ 0.50 gm plot-1 was the most
ecologically sound management practice applied against rice stem borer

AGRIBUSINESS AND MARKETINGPotato is one of the most important cash crops in Bangladesh, and the district of Panchagarh
is one of the major potato producing areas in the country. The objective of this study was to
analyze the value chain of potato in some selected areas of Panchagarh district, including the
profitability, value addition, marketing cost, and net marketing margin of different actors in
the chain. To achieve these objectives, a structured questionnaire was used to interview 25
farmers, 65 middlemen, and 5 cold storage owners from February to April 2023. The data
collected were analyzed using profitability analysis, regression analysis, and moving average
method. The findings of this study revealed that the sales price of potato varied significantly
between different actors in the value chain. The highest sales price per 100kg of potato was
received by the retailer at Tk.2225.00, while the lowest sales price was received by the farmer
at Tk.1625.55. The value addition by different actors in the chain varied from 9.25% to
25.70%, with the wholesaler having the highest value addition. The marketing cost of the
value chain actors varied from 4.51% to 45.90%, with the wholesaler incurring the highest
marketing cost. The net marketing margin of different actors in the chain also varied
significantly, ranging from 6.65% to 47.45%, with the retailer having the highest net
marketing margin. In addition, the seasonal price fluctuation analysis showed that the price of
potato was significantly lower during the peak harvesting period, while it was much higher
before the planting period. Moreover, the study found that proper credit facilities should be
ensured for the value chain actors, as this was mentioned by the highest number of
respondents. The study provides valuable insights into the value chain of potato in
Panchagarh district, and highlights the need for policies and interventions to improve the
profitability and efficiency of the value chain

New distribution record and an updated map of Eutropis multifasciata (Kuhl, 1820) (Squamata, Scincidae) from Dhaka division, Bangladesh
No full textThe Many-lined Sun Skink, Eutropis multifasciata (Kuhl, 1820), has so far been reported from seven localities in Bangladesh. We present the first record of this species from Faridpur district of the country. Our new record extends the distribution of the species by nearly 123 km from its nearest previously known record at Jahangiragar University, Dhaka district, and updates the distribution of this poorly known species in Bangladesh

Unlocking the potential of pomegranate peels as a valuable source of bioactive compounds through effective drying strategies
No full textPomegranate peels are a great resource of bioactive compounds that have potential for various applications, including functional foods, pharmaceuticals, and cosmetics. However, the drying process is an important consideration that can affect the quality and properties of pomegranate peels. This investigation sought to assess the results of different drying procedures that affect the physicochemical, functional, and antioxidant properties of pomegranate peels. Four alternative drying techniques were used such as freeze drying, microwave drying at 900 W, oven drying at 50 °C, and sun drying. According to the findings, the freeze-drying method exhibited the highest total phenolic content (186.24 mg GAE/g DM), DPPH radical scavenging activity (77.86 %), vitamin C (77.5 mg AA/100 g DM), and ferric reducing antioxidant power (31.1 mg AAE/g DM). The sun-drying technique, on the other hand, had the lowest level of quality parameters. The oven and microwave drying methods exhibited comparable results. These findings provide essential information for the optimization of pomegranate peel drying conditions, enhancing its potential to use as a significant source of bioactive compounds for a range of industrial applications. The freeze-drying method is recommended for preserving the quality of pomegranate peels and can be applied in various industries to produce high-quality products
