The experiment was conducted during two consecutive seasons of 2019-2020 and 2020-2021 at Farmers’ home of Kamdebpur village of Nalchity upazila under Jhalakati district (2019-2020) and Bangladesh Agricultural Research Institute, Regional Agricultural Research Station, Rahmatpur, Barishal (2020-2021) to develop suitable protocol of chemical treatment of murta cane for improving the quality of shitalpati (cooling mat) in Bangladesh. There were nine treatments in the experiment viz., T1 = Boiled with Tamarind leaf + Cowa leaf (50g leaf/liter water), T2 = Soaking and boiled with fermented rice starch (250ml/liter water), T3 = Boiled with white vinegar (100ml/liter water), T4 = Boiled with cowa leaf + Vinegar (25g cowa leaf/liter water and 50ml vinegar/liter water), T5 = Boiled with Detergent powder (10g/liter water), T6 = Boiled with Fermented rice starch + Arrowroot (fermented rice starch 250ml/liter water and arrowroot 5g/liter water), T7 = Boiled with Tamarind leaf + Cowa leaf + Rice starch (50g leaf/liter water and fermented rice starch 250ml/liter water), T8 = Boiled with Rice starch + Fermented milk (fermented rice starch: milk = 10: 1), and T9 = Control (no treatment). The experiment was conducted in a Completely Randomized Design (CRD) with three replications. The chemical treatment had significant effect on the quantitative and qualitative traits of murta cane. In terms of qualitative traits, the lowest average value (2.58) was recorded in treatment T7 that denoted from very good to good quality of shitalpati followed by T4 treatment (rating 2.67). The rating from good to moderate qualities of shitalpati were found in T6 (3.33), closely followed by T2 (3.42) and T1 (3.42) treatment. Considering the average value of the qualitative traits (brightness, surface glossiness, surface smoothness and comfort), the treatments T7, followed by T4 and T8 could be applied for the treatment of murta cane towards weaving very good to good qualities of shitalpati.

The field evaluation of betel nut germplasm was conducted at Regional Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Rahmatpur, Barishal all the year round during three consecutive years of 2019-22 to select suitable entry (ies) for releasing as new variety (ies) for Barishal region. Seven entries of betel nut viz., E1 (AC Rah-01), E2 (AC Rah-02), E3 (AC Rah-03), E4 (AC Rah-04), E5 (AC Rah-05), E6 (AC Rah-06) and E7 (AC Rah-07) were used as testing materials. The germplasm had been collected from different regions of Bangladesh since 1973. Three years average results showed that significant variations were observed among the evaluated betel nut germplasm. The maximum fresh and dry nut yield with husk (34.48 and 12.07 t/ha, respectively) was obtained from AC Rah-02 that was identical to AC Rah-01 (28.24 and 10.57 t/ha, respectively). Results revealed that the three years average yield performances of AC Rah-02 and AC Rah-01 were higher compared to that of other tested entries. Maturing condition of AC Rah-01 was late but early maturity was observed in AC Rah-02 and other tested entries. Nut shapes of AC Rah-01 and AC Rah-02 were oblong and oval, respectively. The laboratory analyses results revealed that alkaloids that caused oral cancer was less (3.95 mg/g) and the Ferric Reducing Antioxidant Power that cures the disease was higher (10.20 mgAAE/g) in AC Rah-01. The amount of total alkaloids (1.35%) and Arecoline content (4.69 mg/g) that cause cancer in the mouth were lower in AC Rah-02. Considering yield potentiality, maturity condition (late and early), lower incidences of insect-pest and diseases, and biochemical properties (higher Antioxidant power and lower contents of Alkaloids or Arecoline), AC Rah-01 and AC Rah-02 have been selected as promising entries of betel nut towards releasing new varieties for Barishal region of Bangladesh.

An experiment was carried out at Agricultural Research Station, Bangladesh Agricultural Research Institute (BARI), Dinajpur during the rabi seasons of 2020 and 2021 to find the suitable tomato variety for late planting, when tomato demand and price remain higher on the market. A split- plot design with three replications was used where four planting dates viz., 15 January, 30 January, 15 February and 28 February in main plot and four varieties viz., BARI Tomato-15, BARI Tomato-16, Local (Rani) in sub-plot. . The result showed that both variety and planting dates were a significant effect on tomato fruit yield and yield contributing traits.In case of variety, BARI Tomato-16 gave the maximum fruit yield (51.31 t ha-1) compared to other varieties. Regarding of planting date, 15 January was found suitable time for getting the highest tomato fruit yield (56.79 t ha-1). The interaction effect showed that var. BARI Tomato-16, which was planted on 15 January yielded the higher fruit yield (66.16 t ha-1) followed by BARI Tomato-15 (54.40 t ha-1). Local (Rani) cultivar planted on 28 February produced the lowest yield (25.10 t ha-1). The results of the economic analyses showed that the var. BARI Tomato-16 planted on 15 February had the highest gross return (Tk. 2255000 ha-1), gross margin (Tk. 2057100 ha-1) and benefit cost ratio (11.39) followed by BARI Tomato-16 planted on 28 February.

An experiments were conducted at Agronomy research field, Gazipur and Regional Agricultural Research Station, Jamalpur of Bangladesh Agricultural Research Institute during kharif-1 season of 2018 and 2019 to find out the suitable combination of maize and jute (leafy vegetable) intercropping system for higher productivity and monetary advantage. Treatments included in the experiment were: T1= Hybrid maize normal row (MNR) (60cm × 20cm) + 1 row jute (33%), T2= MNR (60cm × 20cm) + 2 row jute (66%), T3= MNR (60cm × 20cm) + 3 row jute (100%), T4= MNR (60cm × 20cm) + jute broadcast (100%) and T5= Sole maize (60 cm × 20 cm). The experiment was laid out in a randomized complete block design with three replications. At Gazipur, Light availability on jute decreased with the increase of shade produced by maize canopy over the time up to 40 DAS (at harvest of jute) under intercrop situation and the highest light availability was observed on jute in T4 treatment. The maximum grain yield of maize was in sole crop and it was decreased by 1-6 % at Gazipur and 2-9 % at Jamalpur due to intercropping. Maize equivalent yield (MEY) of intercropping treatments showed better performance than sole maize. The highest MEY (19.28 t/ha at Gazipur and 17.41 t/ha at Jamalpur), gross margin (Tk. 252040/ha at Gazipur and Tk. 313380/ha at Jamalpur) and benefit cost ratio (3.65 and 3.33 at Gazipur and Jamalpur, respectively) were observed in T4 treatment among the intercropping treatments. The results revealed that T4 = MNR (60cm × 20cm) + jute broadcast (100%) could be agronomically feasible and economically profitable for maize and jute (leafy vegetable) intercropping system at Gazipur and Jamalpur.

Drought stress can severely affect crop growth and productivity by altering several physiological processes. This experiment was carried out to explore the drought tolerance ability of four mungbean varieties based on their water relation and performance of some growth parameters. The experiment was conducted in pot at Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur from 27th March to 15th May 2017, under a semi-controlled (vinylhouse) condition. Three different water regimes 50 to 60% field capacity (FC), 70 to 80% FC, 90 to100% FC and four mungbean varieties namely BARI Mung-5, BARI Mung-6, BU mug 2, BU mug 4 were used as treatment variable. Among the three water regimes, 50%-60% FC was considered as the severe drought stress. Results indicated significant variations in different traits of both water and growth parameters of the varieties under severe drought stress (50%-60% FC). Among the four mungbean varieties BARI Mung-6 showed superior performance with higher xylem exudation, chlorophyll content, shoot dry matter and lower water uptake capacity at 50%-60% FC (severe drought stress) whereas BU mug 2 showed the lowest performance. Results of this experiment conclude that BARI Mung-6 can be considered as a more water stress tolerant variety than the other three and recommended for cultivation under water limited conditions.

Three different water regimes 50 to 60% field capacity (FC), 70 to 80% FC, 90 to100% FC and four mungbean varieties namely BARI Mung-5, BARI Mung-6, BU mug 2, BU mug 4 were used as treatment variable. Among the three water regimes, 50%-60% FC was considered as the severe drought stress. Results indicated significant variations in different traits of both water and growth parameters of the varieties under severe drought stress (50%-60% FC). Among the four mungbean varieties BARI Mung-6 showed superior performance with higher xylem exudation, chlorophyll content, shoot dry matter and lower water uptake capacity at 50%-60% FC (severe drought stress) whereas BU mug 2 showed the lowest performance. Results of this experiment conclude that BARI Mung-6 can be considered as a more water stress tolerant variety than the other three and recommended for cultivation under water limited conditions.

A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur farm during rabi season of 2017-2018 to evaluate the effects of soil moisture levels and nutrient management on yield, bio-chemical properties and water productivity of black cumin (cv. BARI Kalozira-1) in the Shallow Red-Brown Terrace Soil of Salna series under AEZ-28 (Madhupur Tract). The experiment was set up in a Randomized Complete Block Design (factorial) with three replications comprising 9 treatment combinations having 3 soil moisture levels (Irrigation at 10%, 20% and 30% depletion of soil available water at field capacity) and 3 nutrient management packages: 100% RDF (80-45-50-20-5-2 kg ha-1 of N-P-K-S-Zn-B), 75% RDF + 25% N from cowdung and 50% RDF + 50% N from cowdung. The highest seed yield (1027 kg ha-1), biomass yield (2303 kg ha-1), thymoquinone (3286 mg kg-1 seed), thymol (149 mg kg-1 seed), fixed oil (28.7%), essential oil (0.85%), total consumptive use of water (112 mm) and water productivity (20.5 & 9.14 kg ha-1 mm-1, on the basis of biomass & seed yield, respectively) were obtained from irrigation at 10% depletion of available water along with 75% RDF + 1.98 t ha-1 cowdung. The application of irrigation water at 10% depletion of available water (112.22 mm) with N, P, K, S, Zn and B @ 60, 45, 50, 20, 5 and 2 kg ha-1, respectively + 1.98 t ha-1 cowdung (for supplementing 25% N requirement) appeared to be the best suited treatment package for black cumin cultivation in the study area.

The experiment was conducted at the farmers’ field of FSRD site Deldwar, Tangail to evaluate the agro-economic performance of Okra-T.Aman-Cabbage cropping pattern against farmers’ existing pattern Brinjal-T.Aman rice-Cabbage through incorporation of high yielding varieties and improved management practices during 2018 to 2020. Two cropping pattern viz., Okra-T.Aman rice-Cabbage improved pattern and Brinjal-T.Aman rice-Cabbage farmers’ existing pattern were the treatments variables. The experiment was laid out in randomized complete block design with five dispersed replications Mean data showed that the improved management practices for Okra-T.Aman rice-Cabbage cropping pattern provided higher rice equivalent yield (41.42 t ha-1), production efficiency (368 kg ha-1 day-1) and land utilization index (78 %) over farmers existing pattern Brinjal-T.Aman rice-Cabbage. Average gross return Tk. 667945 ha-1 and gross margin Tk. 452105 ha-1 of improved pattern were 24 and 33 % higher, respectively compared to that of farmers’ pattern with only 8 % extra cost. The marginal benefit cost ratio, land utilization index and production efficiency indicated the superiority of the improved pattern over the farmers’ practices. Bangladesh J. Agril.

Micronutrient deficiency, especially zinc and boron deficiency, commonly occurs in Bangladesh soils. Nevertheless, common diets of this country’s people are often deficient in zinc. Thus, application of zinc and boron has significant value in enhancing crop yield as well as zinc and boron content in crop. With this understanding, field experiments were conducted in two consecutive seasons of 2018-19 and 2019-20 at Bangladesh Agricultural Research Institute (BARI) farm, Gazipur under the agroecological zone 28 (Madhupur Tract). Texturally the soil was sandy clay loam with 6.2 pH, 1.26% organic matter, 0.99 mg kg-1 zinc and 0.13 mg kg-1 boron content. Treatments consisted of a factorial arrangement of three levels of zinc (0, 2, 4 kg ha-1) and three levels of boron (0, 1, 2 kg ha-1) in a randomized complete block design (RCBD) with three replications. Combined application of Zn and B significantly increased the foliage and seed yield as well as their (zinc and boron) contents. On an average, among the treatment combinations, Zn4B1 produced the highest foliage yield (4.55 t ha-1) and Zn2B2 gave the highest seed yield (1.99t ha-1). The highest zinc and boron contents were found in Zn4B2 treatment for both foliage and seeds. Agronomic biofortification of zinc in coriander could be possible without reducing yield through the use of Zn4B1 treatment for foliage purpose and Zn2B2 for seed purpose. Bangladesh J. Agril.

The nature of combining ability and heterosis were studied in an 8×8 diallel cross excluding reciprocals in maize for grain yield and yield contributing characters. Significant estimates of general combining ability (GCA) and specific combining ability (SCA) variances suggested the importance of both additive and non-additive gene actions for the expression of the traits studied. The variances for GCA Was found significant for days to pollen shedding, days to silking, plant height, ear height, 1000- grain weight and yield. SCA was significant for all the characters except yield. Non-significant SCA variance for yield suggests that this trait was predominantly controlled by additive type of gene action. Variances due to GCA were much higher in magnitude than SCA for all the characters indicating preponderance of additive gene effects for the inheritance of these traits. Parents CML431 (P4) and CML285 (P6) were the best general combiner for both high yield and parent CLG1837 (P7) and CML429 (P8) for earliness and dwarf plant type. Seven crosses CL02450×CML451 (P1×P5), CL02450×CLG1837 (P1×P7), CML551×CML431 (P2×P4), CML223×CML451 (P3×P5), CML431×CML451 (P4×P5), CML431× CML429 (P4×P8) and CML285× CLG1837 (P6× P7) exhibited positive SCA effects for grain yield. Considering, BARI Hybrid Maize-9 (BHM-9) as check, the percent heterosis for grain yield varied from -46.17 to 12.14%. Two crosses CML551×CML431 (P2×P4) and CML285× CLG1837 (P6× P7) exhibited significant and positive heterosis 12.14 and 10.77%, respectively over the check BHM-9 suggested their benefit cost ratio (BCR) study for developing high yielding hybrid varieties.
