This study aimed to investigate the cost-benefit per hectare of rice production in haor region Bangladesh. For doing so, multi-stage sampling technique was used collect cross-sectional data during 2018 from four districts producing To achieve purpose, a total 368 randomly selected farming households Habiganj, Sunamganj, Moulvibazar, and Sylhet were surveyed using structured questionnaire. Data ...

This paper aims to establish a tree species identification model suitable for different seasons and regions based on leaf hyperspectral images, mine more effective algorithm. Firstly, the reflectance spectra of leaves in were analyzed. Then, solve problem that 0-element sparse random (SR) coding matrices affects classification performance error-correcting output codes (ECOC), two versions super...

This research was conducted to find out the seasonal (monsoon and post monsoon) variation in gut contents of Labeo calbasu from June November, 2016 Dekhar haor Sunamgonj district, Bangladesh. Three orders phytoplankton were identified content viz. Bacillariophyceae (11 genera), Chlorophyceae (9 Cyanophyceae (4 genera). (6.98±1.61×103cell/L) as most dominant group. Two types zooplankton crustace...

The quality of floral stems depends on a set pre-harvest factors which can influence their postharvest longevity. Although the identification visual signs senescence through scales is decisive in assessing loss period, this scale does not exist for zinnia flowers (Zinnia elegans Jacq.). Thus, objectives study were to evaluate effect different irrigation levels and growing seasons longevity stem...

Superior upland rice varieties can be obtained through the plant breeding process. Upland lines that are carried out from crossing have different potentials. The research aims to determine promising with high yields in acid-dry land. study is conducted on Ultisol soil. first season 2019 for F 6 lines, and second 2021 7 lines. experimental methods use factorial Randomized Block Design (RBD). tre...
