An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh to investigate the yield response of French bean (Phaseolus vulgaris L.) as affected by phosphorus and potassium management. The experiment consisted of two factors. Factor A: Phosphorus fertilizer (4 levels) viz. P1=15Kg P ha-1, P2=20 Kg P ha-1 and P3=25 Kg P ha-1 , P4=35 Kg P ha-1 and factor B: Potassium fertilizer (4 levels) viz. K1=0 Kg K ha-1, K2=20 Kg K ha-1, K3=30 Kg K ha-1 and K4=40 Kg K ha-1. The variety BARI Jharsheem-3 was used in this experiment as the test crop. The experiment was laid out in a randomized complete block design (RCBD) with three replications. In case of phosphorus @ 25 kg ha-1  the highest number of pods plant-1 (4.96), pod length (13.34 cm), number of seeds pod-1 (4.54), weight of 1000-seed (431.21 g), seed yield (1.33 t ha-1), stover yield (1.53 t ha-1), biological yield (2.86 t ha-1) and harvest index 46.50%  were found. In case of potassium @ 40 kg ha-1, he highest number of pods plant-1 (5.80), pod length (14.89 cm), number of seeds pod-1 (4.24), weight of 1000-seed (430.37 g), seed yield (1.53 t ha-1 ), stover yield (1.46 t ha-1 ), biological yield (2.99 t ha-1) and harvest index 51.17% were found. Interaction effect of phosphorus and potassium the highest  number of pods plant-1 (5.18), pod length (13.40 cm), number of seeds pod-1 (4.30), weight of 1000-seed (430.53 g), seed yield (1.40 t ha-1 ), stover yield (1.60 t ha-1 ), biological yield (3.00 t ha-1 ) and harvest index 46.66% were recorded from P @ 25 kg ha-1 and K @ 40 kg ha-1. However, from the study it can be concluded that application of P @ 25 kg ha-1 and K @ 40 kg ha-1 was the most suitable combination for better yield of French bean.

Background: Brucellosis is one of the ancient re-emerging zoonotic diseases which play a significant economic impact on public health and livestock sector. Many studies were carried out on the epidemiology of the disease recently but economic importance was not focused on those studies. This study was conducted to determine the true prevalence and economic impact of caprine and ovine brucellosis in Mymensingh district, Bangladesh. Methods: A cross-sectional epidemiologic study covering all upazilas of Mymensingh district, Bangladesh was conducted during the period from January to December, 2016. The data related to age, sex, abortion record and reproduction disorders were also collected on the sampling day using a questionnaire. Blood samples ( n=2593) were collected from randomly selected native goat and sheep where Rose Bengal Test, Rapid Brucella AB test kit and MAb-ELISA (Monoclonal antibody based blocking Enzyme-Linked Immunosorbent Assay) were used to identify the positive reactors. Results: The prevalence of caprine and ovine brucellosis was estimated to be 1.6% whereas it was found to be 1.56% and 1.64 % in goats and sheep respectively. The prevalence data was incorporated to the economic model to quantify the financial loss due to brucellosis. The total losses attributed to the disease was 48436400 taka (605455 US$) annually in the district whereas 46462900 taka (580786.25 US$) and 1973500 taka (24668.75 US$) in goat and sheep respectively. Conclusions: The study concluded that brucellosis silently constitutes economic loss to the economy of the country and the producers due to insufficient knowledge and inadequate diagnostic facilities, lack of awareness and an effective prevention and control strategy.

An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, and Mymensingh to study the effect of phosphorus and boron on the growth and yield of var. BARI Jharsheem-3 along with French bean during November 2017 to March 2018. The experiment was comprised of two factors involving number of levels viz. phosphorus had four levels  15, 20, 25 and 35 kg ha-1 and four levels of boron viz. 0, 0.5, 1.0 and  1.5 kg  ha-1. Triple super phosphate and Borax were used as source of phosphorus and boron, respectively. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The results exhibited that yield and its contributing characters were significantly influenced by the phosphorus and boron applications. The experimental findings revealed that highest  number of pods per  plant (4.95), pod length (13.06 cm), number of seeds per pod (4.34), and 1000-seed weight (427.99 g), seed yield (1.40 t ha-1), stover yield (1.76 t ha-1), biological yield (3.16 t ha-1) and harvest index (46%) were recorded under phosphorus level at 25 kg ha-1. The experimental findings also revealed that the highest number of pods per plant (4.91), pod length (14.45 cm), number of seeds  per pod (4.36), and 1000-seed weight (427.22 g), seed yield (1.39 t ha-1), stover yield (1.68 t ha-1), biological yield (3.07 t ha-1) and harvest index (45.27 %) were recorded  under boron level at 1.5 kg ha-1. In case of  interaction of phosphorus and boron, the highest number of pods  per plant (5.18),  pod length (14.35 cm), number of seeds pod-1 (4.84), and 1000-seed weight (427.19 g), seed yield (1.86 t ha-1), stover yield (2.05 t ha-1), biological yield (3.91 t ha-1) and harvest index (47.57 %) were recorded under P level at 25 kg  ha-1  and B level at1.5 kg ha-1. So it may be concluded that 25 kg P ha-1 and 1.5 kg B ha-1 could be applied to obtain higher yield of bean.
