Salinity treatment was imposed from 10 days after emergence (DAE) to maturity stage by adding NaCl solution. Salinity stress caused higher reduction in chlorophyll (Chl), carotenoids (CAR), cell membrane stability index (CMSI), biomass and tuber yield plant-1 but increase in contents of catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), glutathione peroxidase (GPX), glutathione S-transferase (GST) and glutathione reductase (GR) activities in all potato varieties and at all the salinity levels. The reduction of Chl, CAR, CMSI, biomass and yield plant-1 were lower in ‘BARI Alu-72’ as compared to other two varieties. Moreover, ‘BARI Alu-72’ showed higher activities of CAT, POD, APX, GPX, GR and GST as well as contents of K+ and lower malondialdehyde (MDA), lipoxygenase (LOX) and Na+ contents in comparison with those of ‘BARI Alu-25’ and ‘BARI Alu-13’. Activities of antioxidants were found moderate in ‘BARI Alu-25’. ‘BARI Alu-13’ showed higher Na+ and Na+/K+ ratio. The results showed that salinity tolerance in potato was manifested by lower decrease in biomass and yield plant-1 with higher antioxidant activities and K+ contents, and lower MDA, LOX and Na+ content than salinity sensitive genotype. \u0000Bangladesh J.

In order to make tomato production profitable postharvest management is very important. The present study assessed tomato postharvest losses in four intensive growing sites of Jamalpur and Rangpur districts of Bangladesh. Farm level postharvest losses were measured through using descriptive and inferential statistics. Cobb- Douglas type multiple linear regression model was used to identify the factors affecting farm level tomato postharvest loss in the survey areas. Farm level postharvest loss of tomato was 12.45% per farm in the survey area. From this3.59% was due to partial damages and the rest 8.86% was for full damages of tomato. The major causes for postharvest loss of tomato were rotten, disease and insect infestation. This loss incurs financial loss at farm level by BDT 152.45 per decimal of tomato cultivation. Total harvested amount, family member and selling price were some of the important factors for tomato postharvest loss in the survey area. Wide practices of improved postharvest management practices are essential to reduce tomato postharvest loss in the survey area. \u0000Bangladesh J. Agril.

A total of 60 banana growing farmers taking each 30 Sabri and 30 Sagar growers were selected from Narsingdi district for collecting data using a pre-tested interview schedule during mid-September to mid-October, 2019. The study revealed that farmers used almost all types of inputs like human labour, organic and inorganic fertilizers, pesticides, and irrigation water in banana cultivation. The cultivations of both Sabri and Sagar variety were highly profitable at farm level since the net returns (Tk.4,29,280/ha and Tk.2,73,995/ha) and BCRs (2.66 and 2.05) were very high. The coefficients of production function revealed that banana sucker, land preparation and Muriate of Potash (MoP) fertilizer positively influenced the yield of Sabri variety banana, whereas only MoP influenced the yield of Sagar variety. The major problems of banana cultivation were lacking of skilled labour, attack of diseases, and high price of fertilizers. \u0000Bangladesh J. Agril.

A total of 100 strawberry growing farmers were randomly selected for this study. Descriptive statistics and Cobb-Douglas (profit) function were used to analyze data. In the farm level 63% of the farmers’ cultivated strawberry in medium high land and majority of them mentioned the soil of their strawberry field was sandy loam (54%) and loam (35%). American Festival and Rabi-3 were found cultivating in the study areas. They performed some intercultural operations like weeding, spraying, and irrigating the crop. Per hectare cost of producing strawberry was estimated at Tk. 7, 30,811 and sapling cost was the major cost item which covered about 37% of total cost. Per hectare net return from strawberry cultivation were found Tk. 15, 57,355 and BCR was 3.13 which indicates strawberry cultivation is highly profitable. Farmers’ experience had positive and cost of hired labour, sapling and chemicals had negative influence on the profitability from strawberry farming. From the results of SWOT analysis it is observed that though it has strength and opportunities of cultivation in Bangladesh, it also has some weaknesses and threats. If the shortcomings are overcome, it is possible to increase strawberry cultivation in Bangladesh. \u0000Bangladesh J. Agril.

The experiment was laid out in randomized complete block design having five different dates of seedling transplant viz. 15 October, 30 October, 15 November, 30 November and 15 December with four dispersed replications.The seedlings transplanted on 15 November recorded significantly the highestnumber of harvested leaves plant-1, weight of single leaf, harvested leaf yield (35.07 t ha-1), siliqua plant -1 and weight of 1000-seed and seed yield (1.38 t ha-1) of mustard green. The highest gross return (Tk. 862800 ha-1) and net return (Tk. 627300 ha-1) with benefit cost ratio (BCR) of 3.66 was obtained from 15 November planting followed by 30 October planting. Conversely, the lowest gross return (Tk.611620 ha-1), net return (Tk. 376120 ha-1) and BCR (2.59) were recorded from 15 December planting. So, last October to mid-November planting would be suitable for economic production of leaves and seed yield of brown mustard in Sylhet region of Bangladesh. \u0000Bangladesh J. Agril.

We did not find the population of Pieris brassicae in this study. In the 1st planting, the lowest percent head infestation (3.79%) were recorded in the pheromone mass trap+ Bt+ SNPV treated plot followed by hand picking + pheromone for trapping S. litura and P. xylostella+ spraying Bt (5.79%) and pheromone for trapping S. litura and P. xylostella+ spraying Bt treated plots (6.01%) as against 10.35% infestation in untreated control. Similarly, the lowest percent head infestation were recorded in the pheromone + Bt+ SNPV treated plot from 2nd and 3rd planting dates 10.85% and 16.33%, respectively. P. xylostella larvae was not found at 1st planting. The highest percent reduction of head infestation over control was recorded from pheromone mass trap+ Bt+ SNPV treated plots which were 63.4%, 49.7% and 46.62% respectively at three planting dates. Significantly the highest marketable yield (56.86 t ha-1)) and highest BCR (4.32) was recorded from pheromone + Bt+ SNPV treated plot in three date of planting. Interaction of pheromone mass trap+ Bt+ SNPV and 1st planting of cabbage was proved to be the most effective management approaches against two leaf eating caterpillars of cabbage. The population of leaf eating caterpillar of cabbage at elarly planting was much less.
