Soil salinity remarkably hinders rice growth, development and productivity. The present study was set up to explore the role of exogenous salicylic acid (SA) and silicon (Si) application on the growth and yield performance of two contrasting rice genotypes, namely BRRI dhan41 (salt-tolerant) and BRRI dhan49 (salt-sensitive) under salinity. The experiment was laid out in a randomized complete block design with three replications and four SA and Si treatments such as control (tap water), 100 ppm SA, 100 ppm Si (as CaSiO3) and, co-application of SA and Si (50 ppm each). Results revealed that the maximum plant height (125.2 cm), fresh weight of shoot (267.3 g) and maximum K+/Na+ (5.2) were obtained in BRRI dhan49 after sole application of Si under salt stress. Besides, the number of grains per panicle and grains per hill significantly increased in BRRI dhan41 after the sole application of SA (64 and 46%, respectively) and co-application of SA and Si (29 and 21%, respectively), and in BRRI dhan49 with sole SA (182 and 277%, respectively) and Si (75 and 446%, respectively) compared with their respective controls. Besides, we observed that the K+/Na+ was increased where the shoot accumulation of Na+ reduced significantly in both rice varieties after sole and co-application of SA and Si compared with the untreated plants. However, the present findings showed new dimensions regarding the beneficial effects of Si on rice plants which could effectively be utilized to grow and maximize rice production in the saline-prone coastal areas of Bangladesh encountering detrimental effects of salt stress on rice.

Sustainable crop production in the era of increasing input price is adding extra burden while the cultivable land is reducing at an alarming pace. This research article aims to test the hypothesis that the leaf cutting as an agronomic practice could be a better prospective in increasing rice grain production. An experiment was carried out in the experimental field of Sher-e-Bangla Agricultural University, to assess the effect of leaf cutting on plant growth and yield of selected BRRI released Aman varieties. The experiment consisted of five rice varieties namely BRRI dhan32, BRRI dhan33, BRRI dhan39, BRRI dhan62, and BRRI dhan56 treated either as control or leaf cutting (except flag and penultimate leaf). The experiment was laid out in randomized complete block design (RCBD) with three replicates. Leaf cutting was observed with detrimental effect on the usual plant growth and yield performances. Irrespective of all studied varieties, the highest value was obtained while no leaf cutting was performed. BRRI dhan39 was found to be the highest yield producing variety in terms of greater flag leaf length, leaf breadth, flag leaf area, required less time to grain filling, filled grain panicle-1, filled grain%, 1000-grain weight, grain yield and harvest index in leaf cutting condition followed by BRRI dhan32 in terms of plant height, chlorophyll content, tiller hill-1 and straw yield. No significant differences in yield contributing parameters except the panicle hill-1 were observed in leaf cutting condition compared to control. Leaf cutting at heading (except flag leaf and penultimate leaves) reduced average 10-20% loss of grain yield. BRRI dhan62 shown highly affected by leaf cutting compared to the rest other varieties. Therefore, it can be concluded by suggesting that leaf cutting reduces plant functional efficiency which can be improved by enhancing photosynthetic capacity through proper management of leaf architecture.

The field experiment was carried out on chilli legume vegetables intercropping system using five treatments at the Agronomy Research Field of Bangladesh Agricultural Research Institute, Gazipur during rabi season, 2019-2020 and 2020-2021. The study was conducted to find out the suitable intercrop combination for higher productivity and economic return. The treatments were viz., T1= Sole chilli (60 cm × 50 cm), T2 = Chilli (100%) + one row bush bean (50%), T3= Chilli (100%) + two row bush bean (100%), T4= Chilli (100%) + one row pea (50%), T5= Chilli (100%) + two row pea (100%). Significantly the highest yield (8.67 t/ha) was obtained in sole chilli. But chilli + one inter row pea intercropping system gave the highest chilli equivalent yield (21.47 t/ha). The highest gross margin (Tk. 151896/ha) and BCR (3.42) were obtained from the same treatment. The results revealed that one row pea (50%) intercropped with chilli (100%) might be suitable intercrop combination for higher productivity and economic return. Bangladesh Agron.

The field experiment was conducted at Agronomy Research Field, BARI, Gazipur during kharif-1 season of 2020 and 2021 to find out suitable combination of maize and dwarf yard long bean intercropping for higher productivity and monetary advantage. Treatments included in the experiment were: T1= Maize normal row (MNR) +1 row dwarf yard long bean (DYLB), T2= Maize paired row (MPR) + 2 rows DYLB, T3= MPR +3 rows DYLB, T4= MPR + 4 rows DYLB, T5= Sole maize (60 cm x 20 cm) and T6= Sole DYLB (40 cm x 25 cm). Light availability on DYLB decreased with the increase of shade produced by maize canopy over the time up to 105 DAS. The lowest light availability on DYLB was observed in T1 treatment and the highest light availability in sole DYLB (T6). The maximum grain yield of maize was observed in sole maize decreased by 1-4 % among the intercrop treatments. The highest maize equivalent yield (13.75 t ha-1), gross return (Tk. 247500 ha-1), gross margin (Tk. 139000 ha-1) and benefit cost ratio (2.28) were observed inT3 followed by T1. The highest land equivalent ratio (1.56) was also found in the same treatment. The results revealed that maize paired row + 3 rows dwarf yard long bean and hybrid maize normal row (60cm x 20cm) + 1 row dwarf yard long bean might be agronomically feasible and economically profitable for maize and dwarf yard long bean intercropping system at Joydebpur.

Mungbean production is decreasing because of inappropriate management of fertilizer and plant population so a study was initiated to find out the effect of different combinations of organic and inorganic fertilizers with different plant geometry on the yield of mungbean var. BARI Mung-5. The experiment was laid out in a split- plot design with three replications. The experiment comprised of three level of plant geometry viz. S1= 20 cm × 10 cm, S2= 30 cm × 10 cm and S3= 45 cm × 15 cm, and six level of fertilizers: F0= Control (without fertilizer), F1= Recommended dose of NPK, F2=5 t ha-1 cowdung, F3=5 t ha-1cowdung with recommended dose of NPK, F4= 2.5 t ha-1 cowdung with recommended dose of NPK and F5=2.5 t ha-1 cowdung with half recommended dose of NPK. Among the three spacing, 30 cm × 10 cm (S2) produced maximum seed yield (1022.8 kg ha-1) while the lowest in S3 (834.4 kg ha-1). Cowdung had a significant effect on the seed yield and yield attributes of mungbean. The maximum seed yield (1038.9 kg ha-1) was obtained F4 while minimum (930.0 kg h-1) by applying cowdung @5 t ha-1. Among the treatment combinations, S2F4 was showed maximum yield (1156.7 kg ha-1) when considering stover yield and biological yield. Plant spacing of 30 cm × 10 cm along with 2.5 t ha-1 with recommended dose of 40, 80, 30 kg ha-1 of Urea, TSP, MoP could be more beneficial for the farmers to get maximum yield from var. BARI Mung-5.

An experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka, during March to May 2018 to study the impact of added urea foliar spray and leaf clipping on growth and yield of mungbean. The experiment was laid out in Split-plot Design with three replications and composed of four levels of urea foliar spray viz. F0 = Recommended Fertilizer (RF) + No Foliar Spray (FS), F1 = RF + 1% Urea FS at Flower Initiation (FI), F2 = RF + 2% Urea FS at FI, F3 = RF + 3% Urea FS at FI and four levels of Leaf clipping viz. C0 = No leaf clipping, C1 = Clipping 1 basal leaf, C 2 = Clipping 2 basal leaves, C3= Clipping total apical leaves having no inflorescence. Results indicated that foliar spray and leaf clipping had significant effect on most of the growth and yield contributing parameters. In case of foliar spray of urea, the maximum plant height, nodules plant-1, highest above ground dry matter plant-1, pods plant-1, pod length, seeds pod-1, 1000 seed weight, seed yield, stover yield and biological yield were recorded from F0. In case of leaf clipping, all growth and yield attributes were recorded highest from C1. Regarding combined effect, the highest growth and yield parameters were recorded from the treatment combination of F0C1. So, F0 along with C1 is suggested for yield improvement in mungbean cultivation. Bangladesh Agron. J. 2022, 25(2): 57-65

An experiment was conducted in the month of November, 2021 at Crop Physiology and Ecology Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh to study the impact of tobacco industry wastewater on germination and early seedling traits of five mung bean accessions (BD-10022, BD-10023, BD-10024, BD-10026 and BD-10027) following factorial completely randomized design (CRD) with three replications. Mung bean accession, tobacco industry wastewater and their interaction significantly interacted on germination and seedling traits of mung bean. Tobacco industry wastewater reduced the germination percentage, germination rate and co-efficient of germination but insisted longer shoot and root as well as escalated the seedling dry weight of mung bean as compared to tap water. Among the five mung bean accessions, BD-10024 and BD-10027 performed comparatively better performance regarding germination and seedling traits, respectively under wastewater conditions.

A field experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka during 2014 on transplant aman rice var. BR11 (Mukta) under different levels of chemical fertilizers and green manures to evaluate its grain yield, grain quality and soil fertility status with incorporation of green manures. The experiment was carried out in a split- plot design with three replications. The level of fertilizers (0, 100, 75, 50% of recommended dose, RFD) was placed in main -plot and levels of green manures management (0, 5 and 10 t ha-1 each Mimosa invisa (Lajjaboti) and Sesbania spp. (Dhaincha) in sub-plot. Recommended dose of fertilizers of 83N, 21P, 37K, 11S and 1.5 Zn kg ha-1, were applied in the form of urea, triple super phosphate (TSP), muriate of potash (MoP), gypsum and zinc sulfate, respectively. Sixty-day old Mimosa invisa and Sesbania spp. were in - vitro incorporated before aman transplantation. Combined application of 75% RFD along with Mimosa invisa @ 10 t ha-1 was proved to be the best management in producing higher grain yield (7.25 t ha-1) and that was at par with treatment 50% RFD plus Mimosa invisa @ 10 t ha-1. Quality of grain was increased markedly in respect of amylose, carbohydrate, and protein as well. Furthermore, the treatment improved soil nutrient status in respect of organic matter, nitrogen, sulfur and Zn over no incorporations of green manures. So, addition of green manure like Mimosa invisa could cut fertilizer cost by 25-50%. Bangladesh Agron. J. 2022, 25(2): 67-72

The experiment was conducted to evaluate the effect of defoliation on grain and fodder yield of maize at the research field and laboratory of Crop Physiology and Ecology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur during the period of December 2018 to June 2019. The trial was carried out in a randomized completely block design with three replications. The experimental treatments were: T1– Control (without leaf removal), T2–Defoliating all leaves except ear and adjacent two leaves above the ear at 7 days after silking (DAS), T3–Defoliating all leaves except ear and adjacent two leaves above the ear at 14DAS, T4–Defoliating all leaves below the ear at 7 DAS, T5–Defoliating all leaves below the ear at 14 DAS, T6– Detopping except two leaves above the ear at 7 DAS and T7–Detopping except two leaves above the ear at 14 DAS. Light intensity was increased (66.9 to 81.05%) when only lower leaves (T5) or both upper and lower leaves (T2) were removed, but when only the upper leaves (T6) were removed it was not increased. SPAD value was increased (13.58 to 24.5%) but number of leaves and leaf area plant-1 were reduced (60.5 to 63.09% and 64.4%) due to defoliation. Substantial amount of green fodder was obtained (0.776 Kg m-2) due to defoliation of maize. Grain yield of maize was reduced (5.56 to 21.83%) due to different defoliation treatments but the yield reduction was not significant when only lower (T4) or upper (T7) leaves were removed.

The experiment was conducted at Dobila, Tarash of Shirajgonj in chalanbeel during the Rabi seasons of 2018-2019 and 2019-2020 to improve the existing cropping pattern, increase cropping intensity, yields and economic return through incorporating of modern crop varieties and improved management practices. The treatments were i) Mustard (var. BARISarisha-14)-Boro-Fallow cropping pattern, ii) Mustard (var. BARI Sarisha-15)- Boro-Fallow cropping pattern, iii) Mustard (var. Tori-7)-Boro-Fallow cropping patternandiv) Fallow–Boro–Fallow (existing cropping pattern). Boro rice (var. BRRI dhan29) was used to improve cropping pattern. The results revealed that the mean crop duration of improved cropping pattern ranged 192-195 days by inclusion of mustard. Rice equivalent yield of improved cropping pattern was 9.51-10.04 t ha-1 year-1 which was 46% higher than that of existing pattern (5.37 t ha-1 year-1). Land use efficiency (53%) of improved cropping pattern were 9 and 47% higher, respectively than those of existing cropping pattern. Higher mean gross return (Tk. 2,80,860 ha-1), gross margin (Tk. 169680 ha-1) and BCR (2.53) were recorded in improved cropping pattern: Mustard (var. BARI Sarisha-14)- Boro – Fallow} due to inclusion of high yielding variety of mustard than existing cropping pattern (Gross return: Tk. 161010 ha-1 and Gross margin: Tk. 86183 ha- 1) in chalanbeel area. Therefore, farmers in chalanbeel region of Bangladesh could follow improved cropping pattern for higher crop productivity and profitability where lands remain fallow before transplanting of Boro rice.
