FARIDI A field experiment was conducted at the research field of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from November 2017 to March 2018, to investigate the effect of nitrogen and phosphorus on growth, yield and protein content of BARI Alu-35. The experiment comprised of two factors, Factor A: Nitrogen levels (4): N 0 = control (0 kg N ha -1 ), N 1 = 75 kg N ha -1 , N 2 = 105 kg N ha -1 and N 3 = 135 kg N ha -1 ; and Factor B: Phosphorus levels (3): P 0 = control (0 kg P ha = 69 kg P ha -1 and P 3 = 92 kg P ha -1 . The experiment was laid in a Randomized Complete Block Design (RCBD) with three replications. The result revealed that nitrogen and phosphorus had significant effects on most of the growth, yield and quality parameters studied in this experiment. Among the four nitrogen levels, N 3 produced the highest plant height (19.72 cm, 34.56 cm and 60.39 cm respectively) at different days after planting, number of leaves plant -1 (11.33, 28.78 and 37.56 respectively) at different days after planting, number of stems hill -1 (4.33), stem dry matter content (17.80%), number of tubers hill -1 (10.11), average weight of tuber hill (74.39 g), yield of tuber (37.73 t ha -1 ), total soluble solids (7.30%), protein content (7.50%) and N 0 produced the lowest results. On the other hand, among the three phosphorus levels, P 2 produced the highest plant height (17.09 cm, 29.93 cm and 52.33 cm respectively) at different days after planting, number of leaves plant -1 (9.33, 24.33 and 32.67 respectively) at different days after planting, number of stems hill -1 (3.17), stem dry matter content (12.65%), number of tubers hill -1 -1 ), P 1 -1 (8.00), average weight of tuber hill (63.17 g), yield of tuber (32.93 t ha -1 ), total soluble solids (5.96%) and protein content (6.16%) and P 0 produced the lowest results. Among the twelve treatment combinations, N 3 P 2 showed highest results and N 0 P 0 showed lowest results. Therefore, the application of 135 kg N ha -1 with 92 kg P ha -1 was suitable for better growth, yield and quality of BARI alu-35.

ARIF A field experiment was conducted at the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh during the period from March to May 2017 to study the effect of different levels of potassium on yield contributing characters of mungbean. The experimental soil was Deep Grey Terrace Soil having pH of 6.4. Six levels of potassium (0, 30, 40, 50, 60 and 70 kg ha -1 ) were used in the study. The experiment was carried out in Randomized Complete Block Design with three replications. Results revealed that grain and stover yield of mungbean (BARI Mung-6) increased with increasing the levels of potassium. The maximum significant grain yield (1209 kg ha -1 ) and stover yields (2742 kg ha -1 ) were obtained with the treatment T 5 (60 kg K ha -1 ) and also gave the highest pods plant -1 , pod length, seeds pod -1 , 1000 seed weight, nodule plant , nutrient contents in seed and stover. Among the six treatments, the T 5 (60 kg ha -1 ) treatment with BARI Mung-6 showed the best performance with maximum yield. The N, P and K contents of mungbean plant increased significantly at maturity stage with the highest doses of potassium fertilizers. Application of potassium fertilizers increased organic matter, N, P, K and B status of post-harvest soil significantly.

The collected samples were carried to the Pesticide Analytical Laboratory, Entomology Division of Bangladesh Agricultural Research Institute (BARI), Gazipur. The collected samples were analyzed using Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) extraction technique and Gas Chromatography (GC) coupled with Flame Thermionic Detector (FTD) for the determination of pesticide residues in 35 samples of country bean and 35 samples of yard long bean. Among the 35 analyzed samples of country bean, 4 samples (11% of the total number of samples) contained pesticide residues of Quinalphos. Among these 4 samples, 2 had residues above the Maximum Residue Limit (MRL) and 2 had residues below the Maximum Residue Limit (MRL) set by European Commission. Similarly out of 35 samples of yard long bean, 5 samples (14% of the total number of samples) contained pesticide residues of Chlorpyrifos, Dimethoate and Quinalphos. Among this 5 samples, 2 had residues above the Maximum Residue Limit (MRL) and 2 had residues below the Maximum Residue Limit (MRL) set by European Commission and 1 sample contained two pesticide residues such as Dimethoate and Chlorpyrifos. The level of detected Dimethoate residue was above the Maximum Residue Limit (MRL), while the level of detected Chlorpyrifos residue was below the Maximum Residue Limit (MRL) in this contaminated sample. Quinalphos and Dimethoate were detected in most of the contaminated country bean and yard long bean samples, while Chlorpyrifos was also detected. This study reflects the overall scenario of pesticide contamination in vegetables especially in country bean and yard long bean available in the local markets of Bogura District, which will help the consumer to be aware of their health and safety.

Factor A: different doses of arsenic [As 0 = No arsenic added (control), As iv 1 = 3 ppm arsenic, As = 6 ppm arsenic, As 3 = 9 ppm arsenic and As = 12 ppm arsenic (soil water basis)] and Factor B: different rice cultivars [T 4 1 = BINA dhan-8, T = BINA dhan-10, T 3 = BINA dhan-14, T 4 = BINA dhan-18, T = BR 14, T 7 = BR 16, T 8 = BRRI dhan28, T 9 5 2 2 = BR 3, T = BRRI dhan29, T = BRRI dhan36, T 11 = BRRI dhan45, T 12 = BRRI dhan47, T = BRRI dhan50, T 14 = BRRI dhan55, T 15 = BRRI dhan58, T = BRRI dhan59, T 17 = BRRI dhan60 and T 18 16 = BRRI dhan61]. Different growth and yield parameters varied significantly due to difference in the doses of arsenic. Arsenic toxicity adversely affects all the growth and yield related attributes of all rice cultivars. BINA dhan-18 produced highest seedling height and BRRI dhan29 produced the lowest. BRRI dhan-61 produced highest shoot weight and BR 3 produced the lowest. BINA dhan-18 produced maximum root length and BRRI dhan45 produced the lowest. BRRI dhan29 produced maximum root weight and BR 3 produced the minimum. BRRI dhan29 produced maximum total dry matter and BR 3 produced minimum. BRRI dhan29 contained maximum N in shoot and BINA dhan-10 contained the minimum. BRRI dhan61 contained maximum P in shoot and BR 3 contained the minimum. BRRI dhan61 contained maximum K in shoot and BR 3 contained the minimum. BRRI dhan29 contained maximum N in root and BINA dhan-8 contained the minimum. BRRI dhan61 contained maximum P in root and BR 3 contained the minimum. BRRI dhan61 contained maximum K in root and BR 3contained the minimum.
