It suffers from various diseases from seedbed to field. Purple blotch (Alternaria porri) and white blotch (Stemphylium vesicarium) simultaneously attack the crop, causing a purple blotch complex. To assess locally available onion cultivars for response to purple blotch complex and yield performance, a three-year experiment was conducted in the net house and research field of Sher-e-Bangla Agricultural University, Dhaka, during the winter of 2010-11, 2011-2012 and 2012-2013. Fourteen onion cultivars, namely BARI Piaz-1, BARI Piaz-2, BARI Piaz-3, BARI Piaz-4, BARI Piaz-5, Taherpuri, Indian hybrid, Lal Teer onion seed, Masud onion seed, Thakurgoan local, Faridpur local, Manikgong local, Indian big and Indian small were used in the experiment. Among the evaluated cultivars, BARI Piaz-3 showed the lowest disease incidence and severity and the maximum bulb yield, followed by BARI Piaz-2 and Indian big. The disease incidence, severity, and yield for BARI Piaz-3 were 54.45-36.33%, 5.75-12.01%, and 10.97-13.89 t/ha, while the corresponding values for BARI Piaz-2 were 41.49, 44.01, and 7.28-10.79 t/ha, respectively. In contrast, Indian big had disease incidence, severity, and yield values of 36.52-58.79%, 15.43-22.96%, and 8.41-10.60 t/ha, respectively.

A total of 62 fish species were identified in the river, including three exotic species, and two prawn species. Out of ten observed orders, Cypriniformes, Siluriformes, and Perciformes were found to be the most dominant, consisting of 19, 16, and 14 fish species respectively. Fishes from Cyprinidae family were revealed to be the most abundant, accounting for about 27.5% of the total fish composition. Besides, among the thirteen common fish groups, catfish’s contribution was the highest followed by perches, carps, and barbs and minnows. However, almost a quarter of all fish species were under threatened category: seven vulnerable, eight endangered, and two critically endangered. Approximately 50% of the total fish species were examined to be rare and very rare.

Broodfish were fed twice a day with experimental diets. Reproductive performance of H. fossilis was evaluated based on growth parameters and fry production of broodstock. The result showed that while the highest (16.37 ± 0.90g) and the lowest (7.03 ± 0.85g) weight gain was obtained in T2 and T4 respectively, however, there was no significant difference between treatments T1 and T3. The FCR of T2 was found to be the lowest followed by T3, T1 and T4, respectively. The highest fecundity was found in T2 (4245.48 ± 347.38) followed by T3 (3747.10 ± 317.99), T1 (3583.96 ± 327.27) and T4 (3191.95 ± 444.55). The rate of hatching and their survival was significantly higher in T2 followed by T3, whereas T1 and T4 showed significantly lower hatching and survival rate.

In order to extricate high salt tolerant soybean genotypes, 13 selected advanced soybean lines, namely BD 2342, AGS 313, G 00207, Galarsum, G 00209, G 00343, G 00028, G 00221, G 00283, AGS 95, G 00062, G 00041 and BD 2330 along with two varieties viz. BU Soybean 2 and Shohag were grown in pots under polyvinyl house at BSMRAU, Gazipur during February to June 2021 following completely randomized design (CRD) with three replications. The plants were exposed to seawater of electrical conductivity (EC) of 5 dSm-1 and 10 dSm-1 from 2nd trifoliate stage till harvest, where control pots were irrigated with tap water (0.3 dSm-1). Results indicated that there was no significant variation in days to first flowering but significant variation was observed in maturity duration among the genotypes. In saline conditions BD 2330, G 00028 and AGS 313 survived longer days which were 96.36%, 80.29%, and 79.53% days to control at 10 dSm-1, respectively compared to other genotypes. Plants of other genotypes died earlier before reaching maturity, especially at 10 dSm-1. The genotype AGS313 expressed maximum leaf relative water content (RWC) at 5 dSm-1 salinity (97.51% of control), while BD2330 showed the highest RWC at 10 dSm-1 salinity (94.76%). The SPAD value showed stable or an increasing trends in BD 2330, AGS 313 and G 00028, where it was in decreasing trend in other genotypes under saline conditions. Unexpectedly, the leaf K-Na ratio did not show any significant relationship with the salt-tolerance among the genotypes. In case of number of filled pods/plant BD2330 produced the maximum (23.33) at 5 dSm-1 salinity, while the genotype AGS313 showed the highest (16.0) at 10 dSm-1 salinity. Genotypes other than BD2330, AGS313 and G00028 did not perform well in pod set, 100-seed weight and grain yield/plant under saline conditions, even at 5 dSm-1.

Two water regimes (irrigated and rainfed) were imposed into main plot and 39 Aus rice genotypes were assigned into sub plots. In order to categorize the genotypes into various groups, multivariate studies including cluster analysis, principal component analysis (PCA), and discriminantfunction analysis (DFA) were carried out using fifteen quantitative plant traits.

Early maturing genotypes are represented in cluster II, and genotypes with outstanding yield performance under irrigation are grouped in cluster III.

However, the outcomes of the sectors are greatly hindered by unexpected disease prevalence, environmental degradation, organic and inorganic pollutants in aquaculture operations, and ineffective feed exploitation to achieve the global food security goal. There has been little research on the impact of nanotechnology on fish nutrition and improved health, despite the fact that the application of nanotechnology in food production systems is being studied globally. In this respect, scientists are generating and inventing new potential ideas and technology to cope with these challenges in aquaculture. Among them, the use of nanoparticles (NPs) has grown in popularity due to their numerous attractive and distinctive features and also tremendous potential to improve aquaculture production. New ideas regarding the application of NPs in fish medicine, drug delivery techniques through NPs, diet formulation to enhance feed efficacy, and as an antiviral or antimicrobial agent to control disease prevalence in aquaculture systems to augment overall production have been discussed. Commercially cultured fish species, including shrimp, Thai koi, Common carp, Grass carp, and Tilapia, have been shown to respond favorably to a variety of nanoparticles (eg. silver, gold, iron, copper, zinc, selenium, and chitosan). Thus nanoparticles researched-based information in finfish and shellfish aquaculture have short-term or long-term prospects and can be used as a potential candidate for nanomedicines combined with fish feed. These new ideas can be studied further before being utilized commercially in the aquaculture fish feed industries and it has huge merit in the future aquaculture need to be considered.\u0000Ann.

Three individual experiments each for tomato, eggplant and potato were laid out in a single factor Randomized Complete Block Design (RCBD) with three replications. Upper storied plant aonla received 100% Photosynthetically Active Radiation (PAR), but incident light was gradually decreased on middle storied (carambola, lemon, dragon fruit) and lower storied (vegetables) in multistoried conditions. The vegetables experienced 50, 78, 98, and 100% PAR in T1 (Multistoried), T2 (Aonla + Dragon fruit + Vegetables), T3 (Dragon fruit + Vegetables) and T4 (Sole cropping of vegetables) treatment, respectively.

The per plant yield reduction was also high in T1 such as potato (40.47%) > tomato (34.29%) > eggplant (33.17%).
