Leaf spot/Tikka disease

The leaf spot or Tikka disease (Cercospora arachidicola and Cercosporidium personatum) of groundnut (Arachis hypogaea L.) is the predominant, devastating, common constraints and economically important foliar fungal disease and major yield reducing factor of groundnut, not only in Bangladesh, but also all over the world. The yield loss was calculated in the groundnut due to early and late leaf spot (Tikka) by over 30-48% in Bangladesh. The efficacy of three botanicals viz. neem leaf (Azadirachta indica), debdaru leaf (Polyalthia longifolia), and datura leaf (Datura metel), BAU-Biofungicide along with a check (Bavistin) and untreated control were evaluated as foliar spray in the field in the present research work. Among the treatments, BAU-Biofungicide, extracts of neem leaf, datura leaf and debdaru leaf showed excellent performance in controlling leaf spot and increasing pod yield by 53.61, 51.91, 40.85 and 38.72%, respectively as compared to control. In case of seedling germination, BAU-Biofungicide as seed treatment+ spray gave 97.77% germination followed by extracts of neem leaf (88.14%), datura leaf (93.33%) and debdaru leaf (95.55%). BAU-Biofungicide as seed treatment+ spray produced higher length and weight of shoot and root and vigour index as compared to untreated control. Maximum vigour index was observed under BAU-Biofungicide spray. BAU-Biofungicide as seed treatment+ spray gave higher plant height, number of leaves and minimum number of infected leaves as compared to control. Minimum percentages of leaf area diseased were obtained with BAU-Biofungicide as seed treatment + spray followed by Bavistin. BAU-Biofungicide, extracts of neem leaf, datura leaf and debdaru leaf showed promising performance in number and weight of pods and pod yield. Maximum weight of pods/plant and weight of mature pods/plant was achieved with BAU-Biofungicide as seed treatment + sprays followed by extract of neem leaf spray. The highest net profit was recorded with the use of BAU–Biofungicide as seed treatment + foliar spray by Tk. 176768.00/ha followed by extracts of neem leaf Tk. 172275.00/ha, while the lowest Tk. 96443.00/ha in untreated control. Maximum Benefit-Cost Ratio (BCR) 1: 2.77 was found in BAU–Biofungicide seed treatment + spray followed by BAU–Biofungicide seed treatment (1: 2.65), BAU–Biofungicide spray (1: 2.64) and extracts of neem leaf (1:2.62).

Bangladesh emerging as a new IT hub in South Asia

IT companies in Bangladesh started exporting software around two decades ago, joining the business process outsourcing (BPO) bandwagon in the 1990s. Since then, many of them have diversified into exporting computer programs, according to Syed Almas Kabir, the president of the Bangladesh Association of Software and Information Services (BASIS).

Kabir’s organization, BASIS, started with 17 companies in 1997. Now, the association has over 1,170 members and several have begun exporting their services globally.

Data Soft, for example, began its journey in 1998. Its Managing Director Mahboob Zaman told DW, “It was 1996 and the world was anxious about Y2K, which could cause a problem for computer systems in 2000. At the time, Indian tech companies announced that they had found the solutions for the problem. We thought if India could do such a lot of things, why couldn’t we?”

Metro rail construction to resume

The government has instructed the Dhaka Mass Transit Company Ltd (DMTCL) to gear up the construction work of the metro rail project (Uttara-Kamalpur) amid the pandemic.

Since March, construction work of the metro rail project has remained suspended. There was little progress at the depot with the government decreeing a public holiday across the country.

According to the DMTCL, only 1% progress was reported in the last three months, with total progress currently being at 45%. Plans had been announced earlier regarding the inauguration of the metro rail by December 16, 2021 to mark the golden jubilee of Bangladesh’s Victory Day.

Road Transport and Bridges Minister Obaidul Quader, at a virtual meeting yesterday with officials concerned, issued instructions on an acceleration of the construction work as it was a top priority project of the government.

“Construction work at public places [of the project] was closed off due to the spread of coronavirus in the country but work continued on a limited scale at the depot and over the viaduct,” said Quader.

“Now, the tempo of the work should be accelerated as it is the first tract project of the government. Along with work from home and assignment, field work must be geared up,” he added.
