Growth and Yield of Tomatillo as Influenced by Planting Time and Macronutrients

With the use of a strategic pairing of planting time and macronutrients, tomatillo growth and yield can be boosted. Due to their complementing effects, the ideal combination of different planting times and macronutrients may significantly boost tomatillo growth and yield. The experiment was set by taking two treatment factors. Our treatment factors were: (1) Planting time (three time’s viz. T1 = 02 November, T2 = 12 November, and T3 = 22 November); and (2) Macro nutrients (four levels viz. F0 = N0P0K0 Kg/ha, F1 = N200P60K100 Kg/ha, F2= N250P90K120Kg/ha, F3 = N300P120K140 Kg/ha). The two factors experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. In case of planting time, the sharp increase of fruits per plant (37.06), fruit weight (42.7 g), yield per plant ( 2.04 kg) and per hectare ( 85.06 t) were obtained from T3 (22 November). In case of macronutrients, the maximum number of fruits per plant (47.26), fruit weight ( 48.47 g), yield per plant ( 2.75 kg) and per hectare ( 114.59 t) were obtained from F1 (N200P60K100 Kg/ha). Combined effect (T3F1) had improved the number of fruits per plant (49.66), fruit weight ( 55.64 g), yield per plant ( 2.94 kg) and per hectare ( 122.84 t), vitamin C content (25.92 mg) and noted from T1F0 (02 November with N0P0K0Kg/ha) treatment combination that minimum number of fruits per plant (14.0), fruit weight ( 24.69 g), yield per plant ( 0.5 kg) and per hectare ( 20.85 t), vitamin C content (16.63 mg). So, the T3F1 treatment combination appeared to be the best for achieving the higher growth and yield of tomatillo.

Effect of Sowing Date and Phosphorus on Growth, Seed Yield and Quality of Fenugreek

The effect of sowing date (three sowing dates viz., S1= 01 November, S2= 15 November and S3= 30 November) and phosphorus levels (four phosphorus fertilizer levels viz., P0= Control, P1= 35 kg P ha-1, P2= 45 kg P ha-1 and P3= 55 kg P ha-1) on growth, seed yield and quality of fenugreek was investigated at Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh, during 10 October 2020 to April 2021. Growth-related data was maximum on S1 (01 November) treatment but S2 (15 November) treatment showed the best result in case of seed yield. In case of growth characters, P3 (55 kg ha-1) revealed the best result but in case of seed yield, P2 (45 kg ha-1) treatment showed the best effect. Under this investigation, it was revealed that the maximum growth was obtained by S1P3 (01 November with 55 kg P ha-1) and the minimum growth was obtained by S3P0 (30 November with control) treatment combination. The maximum pods per plant (52.61), seeds per pod (12.87), weight of individual pod (147.11 mg), the weight of seeds per plant (7.67 g) and weight of 1000-seed (13.86 g), seed yield per plot (306.72 g), seed yield per hectare (2.13 t) and vigor index (570.27) was observed from the treatment combination S2P2 (15 November with 45 kg P ha-1). It was concluded that the combination of sowing date S2 (15 November) along with phosphorus application P2 (45 kg P ha-1) were given the better performance of all the yield contributing parameters and seed yield of fenugreek. So, S2P2 (15 November with 45 kg P ha-1) treatment combination can be repeated in different agro-ecological zones of Bangladesh.

Precipitating factors, clinical features and outcome of diabetic ketoacidosis in children and adolescents admitted in a tertiary care hospital in Dhaka.

Background Information: Diabetic ketoacidosis (DKA) is the leading cause of morbidity and mortality in children with type 1 diabetes mellitus (DM). It is an acute complication of type 1 DM. Objective: This study was designed to identify the precipitating factors, clinical features and immediate outcomes of DKA in children and adolescents. Method: This was a retrospective study which was done in the department of Pediatrics, BIRDEM, from January 2002 to April 2007. Data were collected from the hospital record for all diabetic children below 18 years admitted with DKA. Result: Fourty nine children and adolescents were admitted with DKA. Sixty one percent were known cases and the remaining (39%) were new DM. Majority were female (63%). Most (49%) of the children were between 11- 15 years. Infection was the commonest (49%) precipitating factor followed by insulin omission (24%). Major clinical features were kussmaul breathing (94%) and dehydration (94%).Eighty eight percent patients improved after treatment and mortality was 12%. Conclusion: Infection was the commonest precipitating factor of DKA. Kussmaul breathing and dehydration were the commonest clinical features. Most of the patients improved after treatment.

Evaluation of FVC, FEV1, FEV1/ FVC % in Patients with Chronic Arsenicosis.

Background: Arsenic toxicity from ground water contamination is highly focused public health problem in Bangladesh. Consumption of arsenic contaminated water may be associated with respiratory symptoms and can decrease lung functions along with skin lesion. Proper investigation of this problem is crucial to prevent respiratory complications in these arsenic vulnerable populations. Objectives: FVC, FEV1, FEV1/ FVC % were studied in chronic arsenicosis patients with skin lesion from arsenic exposed area to observe their lung function status. In addition, correlations of these lung function parameters with arsenic concentration in drinking water and duration of consumption were also studied in this group of population. Study design: For this, total 80 subjects age ranged from 20-50 years of both sexes were included. Among them 40 were patients of chronic arsenicosis with skin lesion and were taken in study group and age and sex matched 40 apparently healthy subjects residing in the same arsenic contaminated area but without skin lesion, were designated as control group. Methods: This study was carried out in the department of Physiology, BSMMU from July 2005 to June 2006. FVC, FEV1 and FEV1/FVC % were measured by Digital Spirometer. Arsenic level of the tubewell water was determined by Hybrid Generation Atomic Absorbance Spectrophotometer. Data were analyzed statistically by Chi- square test, Student’s unpaired “t” test and Pearson’s correlation coefficient test as applicable. Results: The mean percentage of predicted values of FVC, FEV1 in exposed non-arsenicosis subjects were within normal ranges. Again they were significantly lower in chronic arsenicosis patients. There was no significant difference in FEV1/FVC% between the two groups. FVC and FEV1 were negatively correlated with arsenic concentration in tube well water in both groups. But FEV1/FVC% was negatively correlated in exposed nonarsenicosis subjects and positively correlated in arsenicosis patients. Again, with duration of consumption of arsenic contaminated tube well water, FVC was positively and FEV1/FVC% was negatively correlated in both exposed non arsenicosis and chronic arsenicosis patients. But FEV1 was negatively correlated in non arsenicosis and positively correlated in chronic arsenicosis patients. But all the relationships were not statistically significant. Conclusion: Therefore, the result of the present study reveals that arsenicosis patients are suffering from respiratory insufficiency. In addition, populations consuming higher arsenic concentration in drinking water are at the risk of lung function impairment and ultimately may lead to respiratory disorder.

Usefulness of bone mineral density measurement in menopausal woman: a study of 217 post menopausal women.

Bone mineral densitometry was done in 217 women in their menopausal period using Dual energy X-ray absorptiometry (DEXA) method. All the patients were presented with different post menopausal syndromes. Quantification of bone mineral density were done in proximal femur and lumber spines of all the patients along with plain X-ray of the sites. One hundred and thirty nine patients showed normal bone mineral density in our study. Rest 78 patients showed declination of bone mineral density from mild osteopenia to severe osteoporosis. We conclude that Dual energy X-ray absorptiometry bone mineral measurement is an unique, non-invasive method in detecting bone mass disorder in post-menopausal women with low back pain and should be the first choice of investigation, for the earliest detection of bone loss and thus fracture risk can be reduced by appropriate management.
