The response of mint (Mentha arvensis L.) to different levels of nitrogen and different levels of water stress were investigated. Relative performances of different growth and yield parameters such as plant height and fresh weight of shoot as influenced by N-fertilizer and water stress were investigated. Pot experiment was conducted with five levels of N treatments- 0, 60, 120, 180, and 240 kg N ha-1 and four levels of water conditions 100, 75%, 50 and 25% field capacity. Plant growth (height and fresh herb (product) was affected by water stress and different N levels. At 100% field capacity, the highest dose of N- (240kg N/ha) Produced maximum plant height (46.33 cm) and fresh herb product. Lower dose of N treatment decreased the plant height and herb product. Compared to 100% field capacity the fresh herb product was drastically decreased from 103.54 -31.67 g pot -1 at 25% field capacity. Key words: Mentha arvensis, Water stress, N-fertilization, Yield of mint.   doi: 10.3329/bjsir.v44i1.2723 Bangladesh J. Sci. Ind. Res. 44(1), 137-145, 2009

A pot experiment was conducted to study the growth response of Indian spinach (Basella alba L) to biogas plant residues. There were seven treatments comprising of control, recommended NPK fertilizer and biogas plant residues (BPR) @ 10, 20, 30, 40 and 50 ton ha-1. The treatments were arranged in a randomized complete block design with three replications. Results indicated that number of leaves; plant height and root length and dry weight of shoot and root obtained with recommended NPK fertilizer were statistically similar to those with control treatment except for number of leaves at 60 DAS. Application of biogas plant residues up to 30 ton ha-1 produced similar number of leaves and plant height compared to control and recommended NPK fertilizer at 30 DAS. At 60 DAS, a significantly higher number of leaves and root length was found with above 20 ton ha-1 biogas plant residues and plant height with above 10 ton ha-1 biogas plant residues than control and recommended NPK fertilizer. Fresh weight of shoot and root found with recommended fertilizer dose were significantly higher than that with the control but lower than that with biogas plant residues above 30 ton ha-1 and 10 ton ha-1 , respectively. Biogas plant residues at 30 ton ha-1 and above gave higher shoot and root dry weight than control and recommended NPK fertilizer. However, there were no significant differences between BPR40 and BPR50 for growth parameters of Indian spinach. The study recommends 40 ton ha-1 of biogas plant residues for enhanced growth of Indian spinach.

Background: Ethnic disparities in cancers are associated with variability in clinical outcomes. We present a Surveillance Epidemiology and End Results (SEER)-based outcome analysis of multiethnic Waldenström's macroglobulinemia (WM) patients. Methods: Adult WM patients diagnosed in 1992 or later (n = 3,175) were analyzed. Median overall survival (OS) was compared across different ethnicities stratified by year of diagnosis, registry identification, age at diagnosis, sex, and marital status. Results: African-Americans (AA) had the youngest median age at diagnosis (63 years) and Whites had the oldest (73 years) (p < 0.001). Female gender, a younger age at diagnosis, and a recent year of diagnosis were associated with an improved OS. Hispanics had the worst (5.6 years) while Whites had the best (6.8 years) median OS. A significant interaction existed between median OS, gender, and race (p = 0.007). Among males, AA had the worst (4.3 years) and Asians had the best (7.3 years) median OS. A significant interaction was also noted between median OS, age at diagnosis, and race (p = 0.033). The worst median OS was seen in Hispanics among patients aged >75 years, and in AA among those aged <65 years. Conclusions: These disparities among WM patients may be multifactorial but need to be explored systematically to better understand the disease biology and for optimal triaging of health care resources.
