The purpose of studying the consequence of COVID-19 on oxbow lake (Baor) fisher's community is to counteract the negative impacts on livelihoods with food security and figure out diversified resilience options for sustaining basic needs of life. Individual questionnaire interviews, oral history, focus group discussion, and telephonic interviews were among the methodological techniques used to gather primary data. The Baor fisher's community was impaired with income, food and feeding habit, health and marketing. The Baor fishers had to stop harvesting or reducing the amount of fish harvest because of gradual decreasing of consumer demand and prices of fish during the course of COVID-19 pandemic period. The transportation costs were raised up to 50%–80%, while the prices of fish decreased by 15%–30% prior to the onset of COVID-19 pandemic. The frequency of fish consumption was significantly come down to 37.5%. Many households substituted fish to farm reared hens, eggs, domestic hens and ducks, lentils, and vegetables during the period of lockdown across the country. Supply chains of fish and fish culture inputswere disrupted due to inadequacy of transportation facilities. Many school- and college-going students were dropped outduring the ongoing pandemic situation due to their financial problems (10%) and early marriage (7.5%). The secondary sources of income (labor of netting in other aquaculture farms) of Baor fisher's community were also impaired. The resilience options of this study will be helpful to minimize the sudden economic crises, ensure dynamic fish value chains and food security, protect individuals from ongoing health hazards, and promote sustainable food production systems followed by social cohesion and stabilityagainst the prevailing challenges owing to the pandemic and other natural calamities.

With the use of a strategic pairing of planting time and macronutrients, tomatillo growth and yield can be boosted. Due to their complementing effects, the ideal combination of different planting times and macronutrients may significantly boost tomatillo growth and yield. The experiment was set by taking two treatment factors. Our treatment factors were: (1) Planting time (three time’s viz. T₁ = 02 November, T₂ = 12 November, and T₃ = 22 November); and (2) Macro nutrients (four levels viz. F₀ = N₀P₀K₀ Kg/ha, F₁ = N₂₀₀P₆₀K₁₀₀ Kg/ha, F₂= N₂₅₀P₉₀K₁₂₀Kg/ha, F₃ = N₃₀₀P₁₂₀K₁₄₀ Kg/ha). The two factors experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. In case of planting time, the sharp increase of fruits per plant (37.06), fruit weight (42.7 g), yield per plant ( 2.04 kg) and per hectare ( 85.06 t) were obtained from T₃ (22 November). In case of macronutrients, the maximum number of fruits per plant (47.26), fruit weight ( 48.47 g), yield per plant ( 2.75 kg) and per hectare ( 114.59 t) were obtained from F₁ (N₂₀₀P₆₀K₁₀₀ Kg/ha). Combined effect (T₃F₁) had improved the number of fruits per plant (49.66), fruit weight ( 55.64 g), yield per plant ( 2.94 kg) and per hectare ( 122.84 t), vitamin C content (25.92 mg) and noted from T₁F₀ (02 November with N₀P₀K₀Kg/ha) treatment combination that minimum number of fruits per plant (14.0), fruit weight ( 24.69 g), yield per plant ( 0.5 kg) and per hectare ( 20.85 t), vitamin C content (16.63 mg). So, the T₃F₁ treatment combination appeared to be the best for achieving the higher growth and yield of tomatillo.

An experiment was conducted during the period of April to July 2019 at Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh to evaluate the yield performance of cucumber influenced by seedling age and training. The experiment was laid out in the Randomized Complete Block Design with three replications. Treatment as three different age of seedling i.e. S₁=15 days old seedling, S₂=20 days old seedling, S₃=25 days old seedling; and four levels of training i.e. T₀=Control, T₁₌Removal of all branches up to 40 cm height, T₂=Removal of all branches up to 80 cm height and T₃=Removal of all branches up to 120 cm height which in combination made 12 treatment combination. ‘Baromashi’ (local variety) was used in this experiment. Different seedling age and levels of training showed significant variations on most of the parameters. In case of seedling age, the maximum average fruits per plant (17.18), individual fruit weight (174.33 gm) and fruit yield (41.63 ton/ha) was recorded from S₃ treatment, whereas the lowest was recorded from S₁ treatment. On the other hand, the maximum average fruits per plant (15.93), individual fruit weight (160.87 gm) and fruit yield (35.97 ton/ha) was recorded from T₁ treatment, while the lowest was recorded from T₀ (control) treatment. In case of combined effect S₃T₁ produced the maximum average fruits per plant (19.45), weight of individual fruit (177.91 gm) and the highest yield (47.73 t/ha) while the lowest were (10.47, 132.40gm and 19.16 ton/ha) recorded from S₁T₀treatment combination respectively. The highest net income (730827 tk/ha) and benefit cost ratio (2.58) was noted from S₃T₁ treatment. It may therefore be concluded that the 25 days old seedling and removal of all branches up to 40 cm height showed more economical than rest of the combinations in cultivation of cucumber.

The influence of elicitors (different types viz., T₁= control, T₂= salicylic acid 50 ppm, T₃= gibberellic acid 100 ppm, T₄= pinching and seed rate (different levels viz., R₁= 8 kg ha^-1, R₂= 10 kg ha^-1, R₃= 12 kg ha^-1) on enhancing growth and seed yield of black cumin was investigated at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, during November 2020 to March 2021. Growth related data was maximum on T₄ (pinching) treatment but in case of seed yield, T₂ (salicylic acid 50 ppm) treatment showed the best result. In case of growth characters, R₁ (8 kg ha^-1 seed rate) treatment revealed the best result but in case of seed yield, R₃ (12 kg ha^-1 seed rate) treatment showed the best result. Under this investigation, it was revealed that the highest seed yield per hector (3.89 t) was found from the of T₂R₃ (salicylic acid 50 ppm and 12 kg/ha seed rate) treatment combination which is statistically similar (3.64 t) to T₄R₃ (pinching and 12 kg/ha seed rate) treatment combination compared (1.61 t) to T₁R₁ (control and 8 kg/ha seed rate) treatment combination. The highest gross return (Tk. 1166520), net return (Tk. 832522) were obtained from the treatment combination T₂R₃ (salicylic acid 50 ppm and 12 kg/ha seed rate) where the lowest gross return (Tk. 485010), net return (Tk. 220500) were obtained from T₁R₁ (control and 8 kg/ha seed rate) treatment combination. The highest BCR (3.57) was obtain from the treatment combination T₄R₃ (pinching and 12 kg/ha seed rate) where the lowest BCR (1.83) was found from T₁R₁ (control and 8 kg/ha seed rate) treatment combination. Economic analysis revealed that the treatment combination T₄R₃ (pinching and 12 kg/ha seed rate) was economically profitable than T₂R₃ (salicylic acid 50 ppm and 12 kg/ha seed rate) treatment combination for black cumin cultivation.
