Intercropping is a popular way to boost crop yield and profitability by maximizing the use of natural and agricultural resources. A study was carried out to establish crop arrangement for sweet gourd and cauliflower intercropping systems. The experiment was carried out during two consecutive years of 2019-20 and 2020-21 to identify the appropriate cauliflower population for intercropping with sweet gourd for increased production and profitability. Seven treatments viz. T1= Sole Sweet gourd (2 m × 2 m), T2=100% Sweet gourd + 3 rows cauliflower 37.5% (60 cm × 50 cm), T3=100% Sweet gourd + 3 rows cauliflower 23% (60 cm × 80 cm), T4=100% Sweet gourd + 4 rows cauliflower 50% (50 cm × 50 cm), T5=100% Sweet gourd + 4 rows cauliflower 31% (50 cm × 80 cm), T6=100% Sweet gourd + 5 rows cauliflower 31% (40 cm × 100 cm) and T7=Sole Cauliflower (50 cm × 50 cm). The maximum sweet gourd equivalent yield (SGEY) 34.83 t ha-1 was obtained from T4. The maximum gross return (Tk. 278640 ha-1), gross margin (Tk. 180384 ha-1), BCR (2.85) and LER (1.40) were also observed from T4 and the lowest in sole cauliflower (T7). The overall results revealed that among the intercrop combinations 100% Sweet gourd+4 rows cauliflower 50% (50 cm × 50 cm) (T4) followed by 100% Sweet gourd + 3 rows cauliflower 37.5% (60 cm × 50 cm) (T2) combinations could be profitable combinations for cauliflower with sweet gourd intercropping system.

Screening of different rice (Oryza sativa L.) germplasms or breeding lines is a continuous effort to identify the promising source. A series of experiments (20) were undertaken to identify promising materials for five years of salinity screening from 2015 to 2019. The materials included total of 3,195 rice germplasm and breeding lines, out of which Bangladesh Rice Research Institute (BRRI) developped 2, 295 germplasms, 193 advanced breeding lines from BRRI, and 707 advanced breeding lines from International Rice Research Institute (IRRI), Philippines. From this study, the genotypes were categorized as 122 tolerant, 220 moderately tolerant, 1,207 sensetive, and 1,646 highly sensetive. Among the BRRI germplasms, most of the materials (61%) had sensitive responses against salinity, while only 2 and 3% of rice germplasm exhibited tolerant and moderately tolerant, respectively. BRRI lines comprised 44% sensetive and 35% highly sensetive rice genotypes. In the tolerance level, 4% appeared as tolerant and 17% moderately tolerant against salinity. Likewise, IRRI lines also showed relatively higher tolerance (9%) than the BRRI germplasm and lines. They were classified into 9 % tolerant and 16 % moderately tolerant rice genotypes.

An experiment was conducted at Central Research Farm, BARI, Gazipur and On Farm Research Division, BARI, Noakhali during Rabi season of 2017-18, 2018-19 and 2019-20 to develop a fertilizer recommendation for chilli with garlic intercropping system. Six treatment combinations viz. T1= 100% RDCF of chilli + 0% RDCF of garlic, T2= 100% RDCF of chilli +10% RDCF of garlic, T3= 100% RDCF of chilli + 20% RDCF of garlic, T4= 100% RDCF of chilli +30% RDCF of garlic, T5= 100% RDCF of chilli +40% RDCF of garlic and T6= 100% RDCF of chilli +50% RDCF of garlic were tested. The experiment was laid out in randomized complete block design with 3 replications. Both chilli and garlic characters significantly influenced by different treatment combinations. The maximum yield of chilli (10.12 and 9.10 t ha-1 at Gazipur and Noakhali, respectively) and garlic (3.70 and 3.55 t ha-1 at Gazipur and Noakhali, respectively) were obtained from T6 treatments which were statistically similar with T5 treatment. Chilli equivalent yield progressively increased with the increase of inorganic fertilizers. The results showed that T6 provided the highest CEY (17.52 and 16.18 t ha-1 at Gazipur and Noakhali, respectively) followed by T5 (17.47 and 16.14 t ha-1 at Gazipur and Noakhali, respectively). The highest gross margin (Tk. 339755 ha-1 and Tk 310198. ha-1at Gazipur and Noakhali, respectively) as well as BCR (4.50 and 4.32 at Gazipur and Noakhali, respectively) were obtained from T5 treatment while the lowest net return (Tk. 266661 ha- 1 and Tk. 242264 ha-1at Gazipur and Noakhali, respectively) as well as BCR (3.92 and 3.76 at Gazipur and Noakhali, respectively) were observed from T1 treatment. Though T6 treatment gave higher yield over all the treatments but it showed lower BCR compared to T5 treatment due to higher cost involvement for inorganic fertilizer. Bangladesh Agron.

The experiment was conducted at Agronomy Research Field of Bangladesh Agricultural Research Institute, Gazipur, during the rabi season of 2018 to 2019 and 2019 to 2020 to find out the suitable crop combination of spinach (Spinacia oleracea) and red amaranth (Amaranthus cruentus) with brinjal (Solanum melongena) for higher brinjal equivalent yield, monetary advantage and maximize land utilization through intercropping system. Treatments were: T1 = 2 rows spinach (50%) in between two rows of brinjal (100%), T2 = 3 rows Spinach (75%) in between two rows of brinjal (100%), T3 = 2 rows red amaranth (50%) in between two rows of brinjal (100%), T4 = 3 rows red amaranth (75%) in between two rows of brinjal (100%), T5 = Sole brinjal ( 80 cm × 60 cm), T6 = Sole spinach (Line to line 20 cm) and T7 = Sole red amaranth (Line to line 20 cm) were used in the study. All the intercropping combinations showed better performance in terms of brinjal equivalent yield, gross return and benefit cost ratio (BCR) over sole crops. Among the intercropping combinations, 3 row spinach (75%) in between two rows of brinjal (100%) was the most feasible and profitable intercropping system in respect of brinjal equivalent yield (34.72 t ha-1), land equivalent ratio (1.57), gross return (Tk. 6,94,346 ha- 1), gross margin (Tk. 4,59,088 ha-1) and benefit cost ratio (2.95). From the two years, results revealed that all intercropping treatments were productive as compared to sole treatments but 3 rows spinach (line to line 20 cm) 75% in between two rows of brinjal (80 cm × 60 cm) 100% intercropped combination might be agronomically feasible and economically profitable.

The experiment was conducted at farmer’s field of Kapasia, Gazipur during November, 2011 to March, 2013under the AEZ 28 (Modhupur Tract).The experiment was carried out to find the effects of varieties and planting dates on growth, yield and quality of sugarcane. Two varieties (viz; Isd 38 and Isd 39) and five planting datesfrommid-November to mid-Marchwere laid out in a Factorial Randomized Complete Block (RCB) design with three replications. Among the varieties, there was no significant difference; however Isd 38 performed better than Isd 39 in all aspect of yield contributing characters. Growth characters viz., tillers and millable cane stalks were significantly influenced by different planting dates. The highest germination (72.17%), tiller (111.03×103 ha-1), millable cane (91.12×103 ha-1), pol % cane (14.91%)and cane yield (75.47 t ha-1) were obtained from mid- November planting and gradually decreased with the advancement of planting times where all the lowest values were recorded from mid-March planting. Interaction between variety and planting date, mid-November planting with Isd 38 produced the highest germination (73.67%), tiller (115.39 ×103 ha-1), millable cane (98.16 ×103 ha-1), pol % cane (14.95%) and cane yield (93.64 t ha-1). The overall results revealed that variety Isd 38 in mid-November planting is optimum for sugarcane production under the Modhupur tract soils of Bangladesh. Bangladesh Agron. J. 2021, 24(2): 73-81

The experiment was conducted at the experimental farm of Agronomy and Farming Systems Division, Bangladesh Sugarcrop Research Institute (BSRI), Ishurdi, Pabna, Bangladesh during 2012-13 cropping season to assess the comparative performance of yield and quality of six tropical sugarbeet genotypes viz., CS 0327, HI 0473, CS 0328, HI 0044, Shubhra and Cauvery. The different genotypes showed significant differences in their yield and yield components, such as beet length, beet girth, beet yield, shoot yield, sugar yield and harvest index. The quality parameters, such as total soluble solids or brix, sucrose percentage and apparent purity percentage of sugarbeet were also different among the genotypes. Maximum beet length (31.38 cm), beet girth (36.09 cm), beet yield (75.46 t ha-1), shoot yield (38.46 t ha-1) and sugar yield (11.82 t ha-1) were found in Cauvery followed by CS 0328. In case of sugarbeet quality, the maximum total soluble solids (TSS) and sucrose percentage (21.90% and 15.68%, respectively) were recorded in Cauvery followed by the genotype CS 0328 (21.52% and 15.50%, respectively). So, it was concluded that tropical sugarbeet genotype Cauvery appeared as the best one with respect to yield and quality parameters followed by CS 0328 under Bangladesh conditions. Bangladesh Agron.

The different genotypes showed significant differences in their yield and yield components, such as beet length, beet girth, beet yield, shoot yield, sugar yield and harvest index. The quality parameters, such as total soluble solids or brix, sucrose percentage and apparent purity percentage of sugarbeet were also different among the genotypes. Maximum beet length (31.38 cm), beet girth (36.09 cm), beet yield (75.46 t ha-1), shoot yield (38.46 t ha-1) and sugar yield (11.82 t ha-1) were found in Cauvery followed by CS 0328. In case of sugarbeet quality, the maximum total soluble solids (TSS) and sucrose percentage (21.90% and 15.68%, respectively) were recorded in Cauvery followed by the genotype CS 0328 (21.52% and 15.50%, respectively). So, it was concluded that tropical sugarbeet genotype Cauvery appeared as the best one with respect to yield and quality parameters followed by CS 0328 under Bangladesh conditions. \u0000Bangladesh Agron.

The experiment was conducted to assess the performance of two popular rice varieties with varying spacing at a farmer's field in Darbost union of Jaintapur Upazila under the Sylhet district of Bangladesh during aman season 2016. Two aman rice varieties (BRRI dhan34 and Binadhan-17), and four levels of plant density (15×10 cm, 20×10 cm, 20×15 cm, and 25×15 cm) were tested in a factorial randomized complete block design (RCBD) with three replications. The results indicated that yield and yield attributes of rice differed significantly due to varieties, spacing, and their interaction. It was recorded that var. Binadhan-17 showed maximum flag leaf length (34.33 cm), maximum number of filled grains m−2 (27855), maximum grain weight m−2 (654.58) contributed to increase grain yield (6.55 t ha−1) in closer spacing (20×10 cm), which ultimately increased grain yield. Therefore, the results of the present study suggested that rice var. Binadhan-17 could be transplanted at 20×10 cm spacing for getting maximum yield (6.55 t ha−1) in northeastern region of Bangladesh. Bangladesh Agron. J. 2021, 24(2): 1-12

Brinjal shoot and fruit borer (BSFB), Leucinodesorbonalis Guenee, is a devastating pest of brinjal (Solanummelongena L.) in all brinjal growing countries across the globe. Ten genotypes of brinjal were evaluated against the pest in experimental field of Khulna University, Bangladesh following arandomized block design with three replications. The genotypes were BARI Hybrid Begun-2, BARI Hybrid Begun-4, BARI BT-4, Begun-4, BARI Begun-9 and BARI Begun-10, Local Cultivar-1, Local Cultivar-2, Local Cultivar- 3, Local Cultivar-4 and BARI Begun-4among the ten brinjal genotypes, reduced shoot and fruit infestation were recorded in local cultivar-1 and BARI Begun 2. On degree of infestation, BARI hybrid BT begun 4 appeared to be resistant while rest of the genotypes were susceptible or highly susceptible. Volume index was documented to be high in BARI hybrid Begun 4 and low in local cultivar 3, while shape index was high in cultivar 2 and low in BARI hybrid begun 4 and BARI Begun-10. BARI Hybrid Begun 4 possessed greater meso and pericarp thickness although those were not resistant. Above all, using resistant genotypes of BARI hybrid BT begun 4 may be considered as a last resort inan optimized IPM package to ensure maximum brinjal productivity. Bangladesh Agron.

Nine experiments were conducted at the Bangladesh Rice Research Institute (BRRI) farm, Gazipur, BRRI regional station, Sagardi, Barisal and farmers’ field of Barisal during Boro, T. Aus and T. Aman season, 2012 to evaluate the NPK briquette efficacy in rice production. Experimental results revealed that deep placement of NPK briquette (2 x 2.4 g) increased rice grain yield about 10 % and it saves 51, 9 and 20 kg NPK ha-1 than BRRI fertilizer recommended rate in Boro season. Similarly, NPK briquette (1 x 3.4 g) produced 28 and 18% more rice grain yield than BRRI fertilizer recommended rate with a savings of 29 kg N and 7 kg K ha-1 in T. Aus and T. Aman season, respectively. In general, deep placement method gave higher grain yield compared to conventional urea application. Undiscounted benefit cost ratio (BCR) was 1.44, 2.40 and 3.20 for Boro, T. Aus and T. Aman, respectively when comparing at the same rates of N application. Thus, use of NPK briquette over urea broadcast and incorporation was economically viable and efficient for rice cultivation. This method helps to reduce N loss through soil-water interface which plays a vital role in reducing environmental pollution. Bangladesh Agron. J. 2021, 24(2): 127-136
2012年Boro、T. Aus和T. Aman季节，在孟加拉国水稻研究所(BRRI)农场、Gazipur、BRRI区域站、Sagardi、Barisal和Barisal农民田间进行了9项试验，以评估NPK型煤在水稻生产中的效果。试验结果表明，深施NPK型煤(2 × 2.4 g)可提高水稻产量约10%，比BRRI施肥推荐量节约51,9和20 kg的氮磷钾(hm -1)。同样，氮磷钾型煤(1 × 3.4 g)比BRRI肥料推荐用量增加28%和18%，在T. Aus和T. Aman季节分别节省29 kg N和7 kg K hm -1。一般来说，深埋法比常规施用尿素能提高籽粒产量。在相同施氮量条件下，百罗、乌斯和安曼的未贴现效益成本比(BCR)分别为1.44、2.40和3.20。因此，在水稻栽培中，氮磷钾型煤施用于尿素投播和混作是经济可行和高效的。该方法有助于减少土壤-水界面氮的损失，对减少环境污染起着至关重要的作用。孟加拉国阿格龙。[j] . 2015,24 (2): 127-136
