EFFECT OF POTASSIUM ON THE GROWTH, YIELD AND NUTRIENTS CONTENT IN TWO VARIETIES OF MUNGBEAN
(Department of Agricultural Chemistry, Sher-e-Bangla Agricultural University., 2013-06) SALAHUDDIN, MD.
The experiment was conducted at the farm of Sher-e-Bangla Agricultural University. Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from March to June 2012 to study the effect of potassium on the growth. yield and nutrients content in two varieties of mungbean. The experiment consists of two factors: Factor A: 2 varieties of mungbean - V j= BAR!mung-2 and V2= BAR! mung-6: Factor B: 4 doses of inorganic fertilizer potassium - K0 = 0 kg K20/ha (control); K1 = 10kg K20/ha; K2 = 20 kg K20fha and K3 = 30kg K70/ha. The two factors experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different yield contributing characters, yield and nutrient content on seeds were recorded and significant variation was observed among the treatments. In case of varieties, at 25. 35, 45, 55 DAS and harvest the tallest plant (22.01 cm, 32.69 cm. 45.99 cm, 53.97 cm and 57.48 cm) was recorded from BAR!mung-6, whereas the shortest plant (20.30 cm. 30.38 cm, 42.13 cm, 49.84 cm and 53.98 cm) from BAR!mung-2. The maximum number of pods per plant (19.48) and highest seed yield (1.60 tma) was recorded from BAR! mung-6, whereas the minimum number of pods per plant (18.13) and lowest seed yield (1.38 tlha) from BAR!mung-2. The highest potassium content in seeds (0.86%) was attained from BAR1 mung-6, again the lowest (0.63%) from BAR! mung-2. For levels of potassium, at 25, 35, 45, 55 DAS and at harvest the tallest plant (22.71 cm, 33.70 cm, 47.63 cm, 55.35 cm and 58.54 cm) was Ihund from 20 kg K20fha and the shortest plant (18.96 cm, 28.46 cm. 38.91 cm, 47.39 cm and 51.95 cm) from 0 kg K20/ha. The maximum number of pods per plant (20.08) and highest seed yield (1.64 tiha) was observed from 20 kg K20/ha. again the minimum number of pods per plant (16.07) and lowest seed yield (1.23 i/ha) was recorded from 0 kg K20/ha. The highest potassium content in seeds (0.84%) was found from 20 kg K,O/ha, whereas the lowest (0.54%) was recorded from 0 kg K20/ha. Consideration of interaction effect of varieties and levels of potassium. at 25. 35. 45, 55 DAS and at harvest the tallest plant (22.89 cm, 33.93 cm, 47.71 cm, 55.66 cm and 59.05 cm) was recorded from BAR1 mung-6 and 20 kg K20/ha, while the shortest plant (17.69 cm, 24.46 cm. 33.67 cm, 42.96 cm and 47.70 cm) from BAR1 mung-2 and 0 kg K20/ha. The maximum number of pods per plant (20.93) and highest seed yield (1.74 tlha) was observed from BARI mung-6 and 20 kg K20/ha, while the minimum number or pods per plant (15.63) and lowest seed yield (1.10 tlha) from BAR!mung-2 and 0 kg K20/ha. The highest potassium content in seeds (0.95%) was recorded from BAR!mung-6 and 20 kg IC2OIha and the lowest (0.40%) from BAR!mung-2 and 0 kg l(20fha. From the above findings it was revealed that BAR!mung-6 and 20 kg K20fha was more elIixtive for the growth, yield and nutrients content of mungbean under the present trial.
HUMAN SAFETY ANDROID APPLICATION
(Daffodil International University, 2018-12-09) SALAHUDDIN, MD.; HABIB, MD. AHSAN
This project is on "Human Safety". Human Safety is a big question in Bangladesh. This is an android based application which needs an android device to run and helps the sufferer in need to emergency help in their critical moment. The aim of the application is to assist the user in finding their relatives or closed people on which time he badly needed them. Using all entire users will be able to get desired feedback. In the development of this application the most essential elements were an android device and an android application development tool. The development of this application is described in the project report. After development session of this application we have tested it by different user and found it to be a well builds application which works perfectly.
