During two successive rabi seasons 2019-20 and 2020-21, a field experiment was undertaken at the Regional Station of Bangladesh Wheat and Maize Research Institute (BWMRI), Gazipur to establish the optimum amount of herbicide application (Gramoxone) before sowing wheat under late-planted conditions. Four optimum doses of application were applied as pre-emergence. Herbicide (Gramoxone) spraying at 6 liter/ha for 5 days before sowing provided the best weed control. The experiment was laid out in a randomized complete block design (RCBD) with 3 replications. The major weeds in the experimental plot such as Biskatali (Polygonium hydropiper), Chapra (Elusine indica), Bathua (Chenopodium album), Banpalong (Sanchus arvensis) and Banmasure (Vicia sativa) were found. Weed count was 92 m2 and 89 m2 in 2019-20 and 2020-20 respectively, when herbicide (Gramoxone) was sprayed @ 12 liter/ha at 5 days before sowing (DBS). Highest weed monitoring efficiency (78%) in T2=herbicide (Gramoxone) treatment @ 6 liter/ha at 5 DBS. Grain yield and wheat biological yield were statistically diverse, while the other metrics were insignificant. When herbicide (Gramoxone) was treated at 6 liter/ha at 5 DBS, a numerically greater average grain yield (2.57 t/ha) was obtained. The control plot produced a numerically lower average grain yield (1.56 t/ha). When herbicide (Gramoxone) was administered at 6 liter/ha at 5 DBS, the maximum benefit-cost ratio (BCR) was 1.30 which is the best method for weed management prior to wheat application.

Milk and milk products are an important source of food that provides nutritional energy, protein, minerals, and vitamins of high quality. Feed supplementation could be an excellent way to improve nutrient digestibility and absorption in dairy cattle, resulting in higher milk output and productivity by addressing the cow's nutritional needs through a feeding schedule. Whatever improvements in the genetic makeup of local dairy cows, they only account for about 30% of productivity; the remaining 70% depend on nutrition, appropriate supplementary diet, and other factors management. Supplementing diverse kinds of feedstuffs and giving a well-adjusted diet has a major effect on milk yield and productivity, but not on milk quality. However, milk production efficiency affects milk quality because of the efficiency of nutrient absorption as described by the ingestion of dry matter. The ability to maximize milk productivity can be determined by the ingredients formulated in the feed supplement. However, local milking cows are minimal milk outcomes since the shortage of nutritional quality and unavailability of feed, if smallholders use appropriate supplementation of different feeds and improve the nutritive values of feeds for dairy cows, the production, productivity, and quality of milk from dairy cattle should increase as well.

5 Reflective Critical Thinking on Education and Teaching during the COVID-19 Pandemic , Ferri Susanto, Md. Rasel Hossain, Mst. Sadia Arefin, and Md. Badiruzzaman
The purpose of this research was to find out Reflective Critical Thinking of Teaching in Class Discussion Learning in the new normal period in the midst of the Pandemic Corona Virus Disease 19 at the Science, Business, Sharia Faculty for the 2021-2022 academic year. Applying critical thinking skills is a challenge for lecturers to find effective teaching alternatives. Qualitative methods and quantitative descriptions were used because the results of the observation and interview processes in the form of percentage values, field notes, and interviews were analyzed. Observational data reveal positive behaviors, ideas, and feelings. Focus on experiences, feelings, and re-evaluation of experiences/ events/ phenomena. Making conclusions or reflective critical thinking commitments that have been carried out by students in class discussions. Perform verbal reasoning, arguments, and decision making. Open questionnaire and interview data revealed the application of Reflective Critical Thinking in class discussions. The results of the research indicated that the discussion class on teaching still lacks the application of reflective critical thinking practices. The impact of the pandemic has resulted in rigidity in learning. This research provides suggestions that Reflective Critical Thinking could be used as a teaching solution in the new normal period.

Research on local breeds of cattle was conducted from November 2018 to April 2019 to identify major Ixodid ticks species and their prevalence. Sampled livestock from farmer associations was contingent selected by multistage sampling technique and then tested for tick infestation. Out of a total of 425 cattle examined, 120(28.57%) were infected with one or more tick strains. About 947 mature ticks were assembled and identified at the level of genes and species from animal organs. Three tick strains of three (3) genera (Amblyomma, Boophilus, and Rhipicephalus) were recognized. The one flesh prevalence of each strain was A. variegatum (61.08%), B. decoloratus (34.69%), and R. evertsi evertsi (4.11%). A. variegatum shows a higher preference for udder, scrotum, and axial; B. decoloratus were dewlap and mainly available Neck, abdomen, and groin; R. evertsi evertsi prefers perianal and valva, and below the tail area of the body. Tested between different age and sex categories of animals, the transmission was constructed to be statistically insignificant (P >0.05) whereas, transmission between body state values was constructed to be statistically significant (P

ABSTRACT The Pandemic caused by the novel coronavirus 2019 has made the governments of both developed and developing countries introduce various restrictive mechanisms in an attempt to lessen the menace and its rapid spread, Nigeria is not an exception. In Nigeria, the Federal Government restricts interstate travel, locked all offices, closed all commercial markets, and imposed a dusk to dawn curfew on the people. Security task forces were deployed across the country to enforce the restriction. Hence, this resulted in an increase in the rate of extortion and corruption among the security operatives, the volume of waste unrecycled was on the high side, ecotourism was affected as well as an increase in the occurrence of sexual assault, cyber fraud, abduction and other related vices in Nigeria. This article intends to review the security issues and social vices on the increase in Nigeria owing to the COVID 19 lockdown as well as provide possible solutions and prevent future occurrences.

ABSTRACT: Lumpy skin disease (LSD) is a generalized skin disease that is an infectious, eruptive, occasionally fatal disease of cattle caused by a virus associated with the Neethling poxvirus in the genus Capripoxvirus of the family Poxviridae. LSD was first described in Zambia and occurs in other most African countries and sporadically in the Middle East region. The genus Capripoxvirus of the family Poxviridae is the causative agent of Lumpy skin disease. Lumpy skin disease virus (LSDV) is closely related antigenically to sheep and goat poxviruses. In Ethiopia, limited works have been done on this disease so far and few studies have been reported on risk factors assessments, epidemiological aspects, seroprevalence, and financial impacts. LSDV transmission among cattle is by the mechanical haematophagus arthropod vectors. LSD is common during the wet season which is at the end of summer and the beginning of autumn. The control of LSD can be achieved through vaccination, restriction of animal movement, and eradication of infected and exposed animals.

ABSTRACT An experiment was carried out at the Soil Science Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during the Aman season to determine the nitrogen requirement of two aromatic rice varieties (Kalizira, and Chinisagar). There were five N levels, viz. N0 (0 kg ha-1), N20 (20 kg ha-1), N40 (40 kg ha-1), N60 (60 kg ha-1) and N80 (80 kg ha-1). Application of N significantly increased the harvest components, grain harvest, and straw harvest of both rice varieties. Both grain harvest and straw harvest of Chinisagar variety were higher than that of Kalizira. There was no significant difference between the two rice varieties for N concentration in grain and straw. The variety Chinisagar showed statistically higher total N uptake compared to the Kalizira variety. The grain harvest of both varieties without any N application was 1.8 t ha-1 and the application of 60 kg N ha-1 recorded the highest harvests of 3.1 and 3.2 t ha-1 in Kalizira and Chinisagar, respectively. For both varieties, the grain harvest increased progressively with an increase in N application up to 60 kg N ha-1 and thereafter decreased at the higher dose of N i.e. 80 kg N ha-1. The grain harvests due to 40 kg N ha-1 may be optimum for both varieties.
