The experiment was conducted at two Regional Spices Research Stations at Gazipur and Magura during July 2012 to June 2014. Experiments were conducted following split plot design with six treatment of two factors of three different shades such as 1) Black mosquito net, 2) Cucurbit trellis and 3) Control (open) and two sowing methods such as i) line sowing with 10cm spacing and ii) Broadcasting were placed in the unit plot. The maximum number of harvested plants (655/m2) and fresh yield (28.52 t/ha) were obtained from broadcast sowing under nylon net shade at Joydebpur while line sowing without shade gave the minimum number of harvested plants (293/m2) and fresh plant yield (16.20 t/ha) at Magura. The maximum gross return (Tk. 4944.2 thousand/ha), net return (TK. 4438.2 thousand/ha) and BCR (1099) was obtained from nylon net shade in broadcast sowing and these was lowest (Tk. 1586.4, 1196.3 thousands/ha and 4.07, respectively) came from line sowing under cucurbits trellis. Cultivation of Eryngium under cucurbits trellis gave early returns that better for fresh leaf production. Open sunlight is less costly but it is not suitable for quality leaf production. Broadcasting sowing under nylon net shade seems better for leaf production and profit.

Abstract With the development of economy, more and more people travel by plane. Many airports have added satellite halls to relieve the pressure of insufficient boarding gates in airport terminals. However, the addition of satellite halls will have a certain impact on connecting flights of transit passengers and increase the difficulty of reasonable allocation of flight and gate in airports. Based on the requirements and data of question F of the 2018 postgraduate mathematical contest in modeling, this paper studies the flight-gate allocation of additional satellite halls at airports. Firstly, match the seven types of flights with the ten types of gates. Secondly, considering the number of gates used and the least number of flights not allocated to the gate, and adding the two factors of the overall tension of passengers and the minimum number of passengers who failed to transfer, the multi-objective 0–1 programming model was established. Determine the weight vector $w=(0.112,0.097,0.496,0.395)$ w = ( 0.112 , 0.097 , 0.496 , 0.395 ) of objective function by entropy value method based on personal preference, then the multi-objective 0–1 programming model is transformed into single-objective 0–1 programming model. Finally, a graph coloring algorithm based on parameter adjustment is used to solve the transformed model. The concept of time slice was used to determine the set of time conflicts of flight slots, and the vertex sequences were colored by applying the principle of “first come first serve”. Applying the model and algorithm proposed in this paper, it can be obtained that the average value of the overall tension degree of passengers minimized in question F is 35.179%, the number of flights successfully allocated to the gate maximized is 262, and the number of gates used is minimized to be 60. The corresponding flight-gate difficulty allocation weight is $\alpha =0.32$ α = 0.32 and $\beta =0.40$ β = 0.40 , and the proportion of flights successfully assigned to the gate is 86.469%. The number of passengers who failed to transfer was 642, with a failure rate of 23.337%.

Low yield is crucial bottleneck for potato production in Bangladesh. The application of vermicompost may enhance the yield of potato. The experiment was consisted of two factors, i.e., Factor A: - Vermicompost level (Vm1-4): Vm1: 0 t ha-1, Vm2: 3 t ha-1, Vm3: 6 t ha-1 and Vm4: 9 t ha-1; Factor B:- Tuber size (T1-5): T1: 5-10 g, T2: 10-20 g, T3: 20-30 g, T4: 30-40 g and T5: > 40 g. The experiment was conducted in a split-plot design with three replications. Vermicompost had significant effect on most of the yield contributing parameters investigated under present study. Results revealed that yield parameters increased with increasing vermicompost level irrespective of tuber size. Among the twenty (20) treatment combinations, vermicompost at the rate of 9 t ha-1 with tuber size > 40 g produced the maximum yield (31.33 t ha-1) that was 53.53 % higher than that of control with 3273.01 $ of monetary advantage. Therefore, present study suggests that potato growers may use vermicompost for increasing yield of potato in Bangladesh. SAARC J. Agric., 19(1): 71-79 (2021)

The experiment was carried out at Agronomy Field laboratory, Department ofAgronomy and Agricultural Extension, university of Rajshahi, to study the effect of irrigation and sowing method on yield and yield attributes of mustard. The experiment consists of two factors i) irrigation viz. no irrigation (I0), one irrigation (I1)and two irrigations (I2) ii) sowing method viz. line sowing method (M1) and broadcasting method (M2). A split- plot design was used for the experiment by assigning the irrigation on the main plots and sowing method to the sub plots with three replications. Irrigation had significant effect on all the yield and yield contributing characters. The highest plant height, number of branches plant-1, filled siliqua plant-1, sliqua length, number of seed siliqua-1, 1000-seed weight and stover yield were obtained from I2 (two irrigations) and consequently it produced the highest seed yield. Sowing method also had significant influence on almost all the yield and yield contributing characters. All the yield contributing characters except number of unfilled siliqua plant-1were found best at line sowing method (M1) and consequently it produced the highest seed yield. However it could be noted from the study that the combination of two irrigations with line sowing method is better to get higher yield of mustard.
