An experiment was conducted during kharif (summer) season 2021 at the substation of Bangladesh Institute of Nuclear Agriculture (BINA), Gopalganj, Bangladesh. Yield and yield contributing attributes of BINA developed four sesame varieties were observed during the trial. A Randomized Complete Block Design (RCBD) with 3 replications was performed. The varieties were V1 = Binatil-1, V2 = Binatil-2, V3 = Binatil-3 and V4 = Binatil-4. Results from the experiment revealed that plant height, number of branches plant-1, number of pods plant-1, pod length, pod breadth, number of seeds pod-1, 1000 seed weight and seed yield were significantly different among the varieties. The tallest plant (106.00 cm) was found in Binatil-1 while shortest plant (77.33 cm) was observed in Binatil-3. It was observed that Binatil-2 had the foremost branches plant-1 (4.80) while the lowest number of branches plant-1 was found in Binatil-1 (0.33). Moreover, Binatil-3 showed the very best number of pods plant-1 (93.33) while Binatil-1 gave the lowest number of pods plant-1 (47.87). The largest pod was found in Binatil-1 (3.74 cm) while the smallest was found in Binatil-2 (2.42 cm). It had been recorded that Binatil-1 showed the maximum number of seeds pod-1 (76.97) while Binatil-3 gave the minimum number of seeds pod-1 (57.60). The highest number of thousand seed weight was recorded in Binatil-3 (3.12 g) while the lowest thousand seed weight was recorded in Binatil-1 (2.93 g). It had been detected that the variety Binatil-2 showed the highest seed yield (1.35 ha-1) while Binatil-1 gave the lowest seed yield (1.25 ha-1). The remarkable growth and yield performance of sesame from kharif season (summer) trial was observed at Binatil-2. And it will be helpful to select the varieties having high yield potential as well as future breeding materials of sesame in Bangladesh. Vol. 9, No. 3, December 2022: 247-251

A laboratory experiment was carried out at the Professor GAF Seed Pathology Centre and Laboratory of Department of Seed Science and Technology, Bangladesh Agricultural University (BAU), Mymensingh during the period of July 2018 to January 2019 to determine the effect of seed sources on quality and health status in some Transplanted Aman rice varieties in Bangladesh. Among the seed sources, the moisture content was recorded from 10.40% to 13.37%. In case of purity analysis of seed pure seed ranged from 39.23g to 39.94g. Germination test of rice seeds was recorded and the percentage of total number of germination ranged from 55.75% to 93.0%, normal seedling (51.50 % to 86.50%), abnormal seedling (4.75 % to 10.75%), fresh ingeminated seed (1.75% to15.0%), hard seed (0.0 % to 11.75%), dead seed (2.75% to 21.25%), respectively. Vigour index in the seed sources ranged from (1255.80 to 2089.86). In dry inspection test apparently healthy seeds (17.74gto 28.92g), spotted seeds (9.8g to 17.34g), deformed seeds (0.36g to 5.58g), discolored seeds (0.34g to 3.40g), inert mater (0.00g to 0.38g), insect damaged seeds (0.00g to 0.24g) and chaffy seeds (0.08 g to 1.14g) were recorded(2.75% to 21.25%), respectively. In the seed health study, seven species of fungi were recorded. In the seed health test Alternaria padwickii (1.25 % to 5.50%), Aspergilus niger (0.0% to 1.75%), Bipolaris oryzae (0.0% to 1.50%), Curvularia lunata (0.00% to 1.0%), Aspergillus flavus (0.00% to 1.25%), Penicillium sp. (0.00% to 1.50%) were recorded, respectively. Most of the farmers were failed to obtain the quality and good health status. In this study, BRRI dhan34 in farmer's seed recorded the highest performance in the seed sources and the lowest performance was recorded in BRRI dhan49 in farmer's seed. Among the seed sources BR22 of BADC seed (T8) performed the best in respect of seed quality and seed health. Vol. 9, No. 2, August 2022: 103-116

A field experiment was executed under sub-tropical conditions during the period from April 2020 to March 2021 to observe the effects of bulb sizes on the flower and bulb yield of tuberose cv. single. The experiment consisted of three bulb sizes namely, a small-sized bulb (1.0-1.5 cm in diameter); a medium-sized bulb (1.6-2.5 cm in diameter) and large sized bulb (2.6-3.0 cm in diameter). Results disclosed that plant height, the number of leaves plant-1, leaf length and breadth, the number of lateral shoots plant-1, production of bulbs plant-1, bulb length and diameter, bulb yield both plant-1 and hectare-1, length of rachis, spike length and diameter, the number of florets spike-1 and flower yield both spike-1 and hectare-1 were increased with the increment of bulb sizes. The longest plant, highest leaf production, larger leaf, bulb production plant-1, bulb size and bulb yield both plant-1 and hectare-1, rachis length, spike length and diameter, number of flowers spike-1, flower yield both spike-1 and hectare-1 were recorded in large sized mother bulb. In contrast, the lowest above the studied parameters were obtained in small-sized mother bulbs. So, large-sized bulbs can be used for commercial production of flowers and bulb of single cv. of tuberose.

Two advanced lines: BR8693-8-4-2-1 and BR8693-17-6-2-2, along with BRRI dhan49 (S. Ck) and BRRI dhan33 (R. Ck) as checks were tested at farmers’ field in eight locations such as West Byde (BRRI Gazipur), Khulna (Dumuria), Habiganj (Sadar), Chapainawabganj (Gomostapur), Rangpur (Sadar), Feni (Dagonbhuyan), Chattagram (Hathazari) and Barishal (Sadar) during the season of  Transplanting Aman 2018. The trial was replicated three times in each location. The unit plot size was 17.94 m2 (4.6m x 3.9m). Seeding emergence for eight locations varied from 11-17 July 2018. Seedling age varied from 25-30 days among the locations. Seedlings were transplanted at 20 cm x 15 cm spacing. NPKS and Zn fertilizers were applied at the rate of 0, 15, 50, 12 and 3.6 kg ha-1, respectively. All fertilizers except urea were applied as basal whereas, urea was applied in 3 equal splits at 10, 25 and 40 days after transplanting (DAT) Other standard management practices were followed as and when necessary. No insecticide was used because the two advanced lines were insect resistant and diseases were not controlled (to identify susceptibility and tolerance level of lines). Date of seeding, transplanting, flowering and maturity, lodging tolerance, pest and disease incidence, phenotypic acceptance at vegetative and ripening stage, yield and yield components were recorded. Among the two advanced lines, BR8693-8-4-2-1 line was statistically significant from BR8693-17-6-2-2, BRRI Dhan49 and BRRI Dhan33 respectively and the disease reaction, farmers’ opinion, and special character of insect resistant, BR8693-8-4-2-1 was found to be superior for further variety trial. The main purpose of the experiment is to recommended insect resistant rice genotype for proposed variety trail. For yield estimation, 9 m2 sample area from each plot was harvested at maturity and grain yields were adjusted to 14% moisture content.

Despite the fact that people are more familiar with its drawbacks, water hyacinth has a variety of uses. This study aims to assess local inhabitants' opinions of water hyacinth and its sustainable, environmentally beneficial uses. In order to perform the study properly, we moved on to the study areas that are closer to Roa beel and a questionnaire with seven components and seven parameters was used. The Roa Beel is situated in the Chandpur Union neighborhood of the Kishoregonj district's Katiadi Upazila, Kishoreganj, Bangladesh. During the rainy season, excessive water hyacinth was found in the study region, and people of the villages of Sheker Para, Purbo Para, and Modinas Para in the Kishoregonj district were surveyed. The study assesses the locals' perceptions of their knowledge and understanding of water hyacinth, their management techniques, the benefits and drawbacks of water hyacinth, and their actual use of it in their daily lives as well as in various sectional activities like fishing, livestock rearing, agricultural farming, particularly in floating agricultural practices, and for industrial purposes. A surplus of water hyacinth in the beel can be utilized to create a promising industry for the region, especially if it is converted into affordable, environmentally acceptable animal feed, bio-fertilizer, and biogas. Undoubtedly, this will improve local environmental management efforts and provide more opportunity for local unemployed people to find employment.
