Globally, food insecurity is a fundamental problem. The aquaculture sector plays a vital role in supplying food with great potential to enhance food security. A significant challenge for the industry is the scarcity of protein sources in fish feeds and high prices that escalate production costs beyond economic viability. A growing paradigm shift for sustainability in the aquaculture sector is the usage of alternative insect-based diets like the black soldier fly (Hermetia illucens) larvae meal (BSFLM). The cost of fish production is always a pertinent issue in the aquaculture sector. Therefore, farmers would benefit from minimised and feed costs using technologies such as linear programming, which considers input costs and nutrient levels on different feed ingredients to ensure the production of least cost nutrient-dense diets. This study focused on applying the linear programming technique in Nile tilapia (Oreochromis niloticus) feed formulation using BSFLM as an alternative source of protein. In determining the least cost diet, five feeds were formulated with BSFLM at the following levels (0, 25, 50, 75, and 100%) using ready to use excel solver function for linear programming. The study shows that replacing fishmeal with BSFLM at 100% is cost-effective and may reduce the cost of feeding by as much as 26.8%. This study focuses on minimising feed cost in the aquaculture.The study recommends that a further study be conducted to test the diets on fish growth performance.However the level of pprotein content in the diets formulated is also a good since they meet the requirements for juvenile nile tilapia.Reduced feed costs will enable aquaculture farmers to increase their income and enhance food security.

Wheat in Bangladesh under late sown conditions is often exposed to heat and moisture stresses resulting in poor growth and reduced yield. Seed priming can be a feasible tool to combat those abiotic stresses. The objectives of the present study were to evaluate the efficacy of different seed priming agents for increasing seed emergence, seedling growth, and vigor of wheat. A laboratory experiment was conducted at the Agro Innovation Laboratory, Department of Agronomy, Bangladesh Agricultural University during the 2nd week of November in 2019 with the wheat variety BARI Gom-33. The experiment comprised the following two factors arranged in a completely randomized design with four replications; Factor A: Priming agent (23) namely; (i) Control (No priming) (ii) Hydropriming (distilled water) (iii) 10000 ppm NaCl (iv) 20000 ppm NaCl (v) 30000 ppm NaCl (vi) 50 ppm PEG (vii) 100 ppm PEG (viii) 150 ppm PEG (ix) 1 ppm Na2MoO4 (x) 2 ppm Na2MoO4 (xi) 3 ppm Na2MoO4 (xii) 5000 ppm ZnSO4 (xiii) 10000 ppm ZnSO4 (xiv) 15000 ppm ZnSO4 (xv) 25 ppm CuSO4 (xvi) 50 ppm CuSO4 (xvii) 75 ppm CuSO4 (xviii) 10000 ppm KCl (xix) 20000 ppm KCl (xx) 20000 ppm KCl (xxi) 10000 ppm CaCl2 (xxii) 20000 ppm CaCl2 (xxiii) 30000 ppm CaCl2; Factor B: Priming duration (2); (i) 6 hours (ii) 12 hours. One hundred seeds were placed manually on moist sand maintaining more or less equal distance in each petri dish. Results revealed that seed priming has a positive impact (except CuSO4 and ZnSO4) on seed germination and seedling growth of wheat. Germination parameters and seedling growth traits were significantly affected by priming agents, and a clear advantage of seed priming over non control was evident. Seed priming for 12 hours performed better than6 hours priming. Among the priming agents tried, CaCl2 performed the best in terms of germination percent and index, root and shoot length, seedling length, dry weight and vigor were. It may therefore be concluded that seed priming can increase seed germination rate and improve seedling vigor of wheat to some extent, and pre-sowing seed priming with CaCl2 for 6 hrs can be recommended for wheat.

BACKGROUND: The study of ethno-botanical is important in different sectors like medical and agriculture so the discovery, exploration and documentation of such plants is necessary. This research assessed the phytochemicals present in the selected plants and studied their allelopathic effect on germination, radicle length, and plumule length of bean and radish seeds. METHODOLOGY: The research was conducted in the Agroecology lab of Institute of Agriculture and Animal Sciences (IAAS )Paklihawa. Six plants such as Camellia sinensis, Zanthoxylum armatum, Amomum subulatum, Eupatorium glandulosum, Cymbopogan flexuosus, and Rhododendron arboreum were selected and collected from different districts of Nepal. The collected plant parts were dried, powdered, and aqueous extract was used to screen some secondary metabolites. Six treatments @ 10% aqueous concentration of extracts including control were applied in bean and radish seeds in CRD format along with 3 replications to study their allelopathic effect. KEY FINDINGS: Glycoside was detected in all the extracts, and alkaloid was also detected in all the extracts except in the extract of Rhododendron arboreum. Alkaloids, flavonoids, terpenoids, and saponins were found highest in Eupatorium glandulosum leaves (5.2%), Camellia sinensis (1.4%), Cymbopogan flexuosus (7.03%), and Camellia sinensis (2.12%) respectively. The reading of germination rate for bean and radish seeds was found lowest in Camellia sinensis extract and Eupatorium glandulosum extracts respectively. Average length of radicle and plumule of both bean and radish seeds was found highest in the extract of Rhododendron arboreum and least in an extract of Eupatorium glandulosum. CONCLUSION: In conclusion the selected plants possess many secondary metabolites that inhibited the development of the bean and radish seeds to grow vigorously hence upon further research and trial, these plants could be a wonderful source of herbicides to suppress the growth of unwanted weeds in the field.

The aim of the present investigation was to assess the allelopathic potential of 25 Bangladeshi legume plants against the seedling development of the allelopathic-sensitive plant Raphanus sativus L. Five distinct concentrations of these plant species' aqueous leaf extracts viz., 1:05, 1:10, 1:15, 1:20, and 1.25 (w/v) were employed. Every time, distilled water (with no extract) was acted as a control, and the bioassay test was repeated three times. The inhibitory actions relied on concentration and the shoot growth was less responsive to plant extracts than the root development. The shoot growth of R. sativus was less inhibited (70%) by lentil (Lens culinaris) leaf extract whilst African dhaincha (Sesbania aculeate L) at concentration of 1:05 (w/v) provided the highest inhibition (100%). At a concentration of 1:10 (w/v), the root of Krishnochura (Delonix regia), Sada koroi (Albizia procera), Radhachura (Peltophorum pterocarpum), Minjiri, (Cassia siamea), Polash (Butea monosperma), Ipilipil (Leucaena leucocephala), Tripatri shak (Desmodium triflorum), Country bean (Lablab purpureus), Black gram (Vigna mungo), Ground nut (Arachis hypogae), Yardlong bean (Vigna unguiculata) and African dhaincha (Sesbania rostrata) exhibited the highest level of inhibition (100%) while Bokful (Sesbania grandiflora), had the lowest level of inhibitory activity (87%) at the same concentration. Comparing root growth inhibition (ranged 56–81%) to shoot growth inhibition (ranged 37–77%), the aqueous leaf extracts of legume plants demonstrated a lower level of inhibition on shoot growth. Lentil (Lens culinaris) provided the lowest average inhibition (37%) on the development of R. sativus shoots and Faba bean (Vicia faba) provided the greatest average inhibition (77%). Meanwhile, Tripatri shak (Desmodium triflorum), a herb legume, provided the least average inhibition (56%) on the root development of R. sativus (56%) and Winged bean (Psophocarpus tetragonolobus) offered the greatest (81%) level of inhibition. Compared to the categories of legume species the shrubs had the most limitation on the growth of R. sativus shoots (65%), whereas herb species had the least (60%) of this effect. However, the tree species had the most root growth inhibition (70%) while the herb species had the lowest (68%). According to the findings, African dhaincha (Sesbania rostrata), followed by Soybean (Glycine max), Faba bean (Vicia faba), Blackgram (Vigna mungo), and Winged bean (Psophocarpus tetragonolobus), are prospective candidates among the examined legume plant species that have substantial allelopathic features and may be used for further allelochemical extraction and characterization.

Nowadays, modern agriculture has benefited from Precision Agriculture (PA) through incorporation of technological advances like the use of GIS (Geographic Information Systems), RS (Remote Sensing), GPS (Global Positioning System) and advanced information processing. Based on the GIS, RS and GPS, a study was conducted to develop a cropland map using GIS and remotely sensed unsupervised algorithm for suitability analysis of paddy harvester. The research was carried out at four selected locations such as Kulbaria-Baratia, Mundopasha, Charwapda, and Holdibaria villages of Dumuria, Wazirpur, Subarnachar and Kalapara upazilas of Khulna, Barishal, Noakhali Patuakhali districts, respectively in the southern Bangladesh. The satellite images for GIS mapping were captured at vegetation stage of Boro-2018 and Aman-2018 during March-April and October-November. Technical performances of reaper and combine harvester were used to determine the required number harvester based on the estimated cultivated area found through GIS maps. The calculated required number of a) reaper, b) mini combine and c) medium combine to cover the estimated paddy area are a) 17 and 16, 1 and 5, 38 and 127, 6 and 21, b) 35 and 32, 3 and 10, 76 and 254, 13 and, 42 and c) 10 and 9, 1 and 3, 21 and 72, 4, and 12 during Boro and Aman seasons at Kulbaria-Baratia, Mundopasha, Charwabda and Holdibaria of Dumuria, Wazirpur, Subarnachar and Kalapara upazilas, respectively. The estimated results revealed that GIS tools and remote sensing are helping in simplification and visualization by incorporating data sets which can supports decision making for the implementation of paddy harvesting technologies in order to ensure the proper agricultural mechanization. Based on the accuracy assessment, GIS tool is found very useful to assess area to be harvested mechanically with specific type and number of harvester. It can be considered for formulating mechanized harvesting policy through further research in other areas.
