An attempt was made to assess the adoption status of BARI Malta-1 (sweet orange), its farm level profitability, problems and the impacts of malta cultivation on the livelihood of farmers. A total of 180 farmers, 60 farmers from each district were randomly selected for this study. The study revealed that 91% farmers adopted BARI Malta-1 in their gardens. Higher yield, profitability, sweetness, and less insect-pests infestations were the major reasons for choosing BARI Malta-1 at farm level. Farmers did not follow the recommended doses of manures and fertilizers due to lack of adequate knowledge on recommended doses. The establishment cost of a malta garden was Tk. 7,02,650 per hectare. The highest yield (19.6 t/ha) and gross return (Tk. 15,68,000/ha) were obtained from 5th to 10th year gardens. The lowest return (Tk. 8,28,160/ha) was reported in the 3rd year garden. Scarcity of saplings, un-attractive colour, and lack of technical know-how were the major problems to BARI Malta-1 cultivation. The study suggested availability of saplings, hands-on training to the farmers, and affordable price of different input for higher adoption of this variety. \u0000Bangladesh J. Agril.

The design of the experiment was completely randomized design having 2 replications. The unit plot size was one row of one meter length with 50 cm row to row and 20 cm plant to plant spacing. Two second instar larva of C. partellus (Swinhoe) per plant were released two times, first at 8th leaves (vegetative) and second at 12th leaves (Before tasseling) stages. Insect damage parameters (IDPs) viz. dead heart percentage, damage % at vegetative and foliar stage, foliar injury rating (1-9) at vegetative and before tasseling stage, tunnel length (cm), exit hole number and yield per plot were recorded to study the germplasm susceptibility level. The result revealed that IDPs and yield varied significantly among the tested genotypes. Over the years, IDPs like dead heart percentage (5.17%), percent damage atpre-tasseling stage (10.6%), foliar injury level (2.25), tunnel length (10.15 cm) and exit holes (2.32) were found lower with high yield (2235 g/plot) in RML-95/ RML-96 followed by RML- 86/RML-96. Two pipeline maize hybrids RML-95/RML-96 and RML-86/RML- 96 with least damaged by maize stem borer in both years will be useful for maize stem borer resistance source. \u0000Bangladesh J. Agril.

Among the respondents 71% were belonged to small farm size category followed by medium (21%) and marginal farm size category (6%). Average per hectare postharvest loss was 3929 kg in the survey areas. Postharvest loss was found highest in Rangpur (5781kg) followed by Rajshahi (4075kg) and Bandarban (1931kg). Total postharvest loss was 51.79% due to complete physical damage and the rest (48.21%) was due to partial physical damage. Sorting and grading stages accounted to 27.52% and 24.98% respectively were responsible for complete physical damage and partial physical damage.

Three NaCl mediated salinity levels (0, 8 and 12 dS m-1) were used with two ALA concentrations (30 and 60 mgL-1). Saline stress decreased plant height, root length, leaf area, dry mass accumulation, chlorophyll content, photosynthetic parameters, and K+, while proline (Pro), Na+, Na+/K+ ratio, antioxidant enzymatic activities, hydrogen peroxide (H2O2), superoxide (O2 •-), and melondialdehyde (MDA) content increased. Saline stressed mustard seedlings treated with 30 mgL-1 and 60 mgL-1 foliar application of ALA ameliorated the saline mediated inhibition in seedling growth i.e. increased plant height, root length, leaf area, and dry matter. ALA had also increase chlorophyll (Chl) content, net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci) and transpiration rate (Tr), proline content as well as the activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX).

The trial was laid out in a randomized complete block design with three replications. Maize var. BARI Hybrid Maize-9 and short duration T. aman rice var. BRRI dhan56 /BRRI dhan57 were used. Sowing time is critical for maximizing yield for both grain and biomass yield of maize. Yield and yield attributes of maize varied significantly due to different sowing dates. The result showed that grain yields of maize 8.48, 11.20, 8.22 and 7.98 t ha-1 were achieved with seed sown on 10 November as relay with T. aman rice, 20 November as relay with T. aman rice, 30 November in T. aman harvested fallow land and 10 December in T. aman harvested fallow land, respectively. The highest grain yield (11.20 t ha-1) was obtained when sowing on 20 November as relay with T. aman rice, which showed an increase of grain yield of 40, 36 and 32 % than 10 December in T. aman harvested fallow land, 30 November in T. aman harvested fallow land and 10 November as relay with T. aman rice, respectively. The highest gross return (Tk. 2,30,095 ha-1), net return (Tk. 1,33,845 ha-1) and benefit cost ratio (2.39) were noted in the same treatment indicated the profitability of maize in zero tillage as relay with T. aman rice in AEZ 20. \u0000Bangladesh J.
