BARI broccoli 1 2021-02-03T22:12:01+00:00 <p>A two factorial experiment with nine treatment combinations was conducted at Agricultural Research Station (ARS), Pahartali, Khulshi, Chattogram during Rabi season 2019-2020 to find out the best seed production technology for broccoli. These two factors were spacing and curd management. In case of siliqua/ plant, the highest number of siliqua (2453) was acquired from treatment H<sub>2</sub>S<sub>2</sub> (de-heading with 60 cm × 60 cm spacing) followed by treatment H<sub>1</sub>S<sub>2</sub> (scooping with 60 cm × 60 cm spacing) which was documented as 2054. On the other hand, treatment H<sub>3</sub>S<sub>3</sub> (no de-heading with 50cm × 40 cm spacing) produced lowest number of siliqua/ plant which is documented as 677. Treatment H<sub>2</sub>S<sub>2</sub> (de-heading with 60 cm × 60 cm spacing) also provided the maximum seeds/ siliqua (9.40), 1000 seed weight (4.37 g) and seed yield (680 kg/ha) .The highest length of siliqua (5 cm) was obtained from treatment H<sub>3</sub>S<sub>2</sub> (control with 60 cm × 60 cm spacing) and the lowest length of siliqua (4.55cm) was obtained from treatment H<sub>2</sub>S<sub>3</sub> (de-heading with 50cm × 40 cm spacing). Treatment H<sub>3</sub>S<sub>3</sub> (control with 50cm × 40 cm spacing) provided lowest seeds/ siliqua (6.50). Treatment H<sub>1</sub>S<sub>3</sub> (scooping with 50 cm × 40 cm spacing) produced the lowest 1000 seed weight (3.17g). The BCR of broccoli was very high due to the high price of broccoli seed. From the result of BCR, it is clear that de-heading of curd is more profitable than scooping and control for the seed production of broccoli. Among de-heading technique, H<sub>2</sub>S<sub>2</sub> is more profitable as suggested by its higher BCR (41).</p> 2021-02-07T00:00:00+00:00 Copyright (c) 2021 Journal of Agricultural Science & Engineering Innovation (JASEI) [U.S. ISSN 2694 -4812] The Study of Macro Invertebrate Fauna in Wetland Areas of Lokoja, Nigeria 2020-12-30T06:43:58+00:00 Abidina Abba Ukwedeh Ojoniko Mary Kachi Jolly Babangida Alhassan Abdulrahman <p>The analysis of the macro invertebrate assemblage in the wetlands of Lokoja and physico-chemical parameters; based on anthropogenic events across catchments of the wetland, sampling stations were allocated. From January to June, ecological parameters such as air and water temperature dissolve oxygen concentration, depth and pH levels as well as the macro invertebrate fauna were assessed. The analysis found that the temperature of air and water was highest in the March (31.42±1.0◦C) and April (38.3±0.5C) respectively; Average Depth and dissolve oxygen concentration of the water were higher in June (0.55 ± 0.07 m) and (5.30±0.92 mg/l) each, while pH was higher in May (5.73±0.68). Similarly, the overall macro invertebrate was frequent during the dry season compared to the rainy season. Higher abundance was observed in the month of April with Coleopterans being highest followed by Orthoptera; followed by May and June. We observed changes in the growth dynamics of macro invertebrate fauna from April to subsequent May and June. Our findings revealed the state of macro invertebrate fauna in the wetland Areas of Lokoja, secondly we highlighted the condition of pollution in the wetland areas as such we recommend restoration of the wetland so as to increase ecological efficiency of the wetland as well as wastewater management framework aim at eradicating elicit environmental pollution by humans into the aquatic ecosystem.</p> 2021-01-27T00:00:00+00:00 Copyright (c) 2021 Journal of Agricultural Science & Engineering Innovation (JASEI) [U.S. ISSN 2694 -4812] Variability studies of guava (Psidium guajava L.) genotypes for growth, yield and quality attributes in Chattogram region of Bangladesh 2020-10-07T21:14:03+00:00 Md. Golam Azam M Shalim Uddin SM Kamrul Hasan Chowdhury ASM Harunor Rashid Haimonti Barua Rozina Afroz Chhanda Sajia Rahman Shamim Ara Bagum Mossammat Shamsunnahar Md. Nazirul Islam <p>Guava (<em>Psidium guajava</em> L.) is considered as an important profitable fruit in Bangladesh. The study was conducted in the fruits orchard of Agriculture Research Station (ARS), Pahartali, Chattogram and Regional Agriculture Research Station (RARS), Hathazari, Chattogram during 2019-20 to assess the genetic diversity of the in situ guava germplasm. Twenty two guava lines were assessed in this investigation. A total of 21 traits (11 qualitative and 10 quantitative) enabled an assessment of the genetic variability and construction of this guava germplasm. The maximum variation was observed in pulp color and seediness in guava fruits. Plant height ranged from 2.38 to 6.20 m with an average 3.85 m. Based girth ranged from 28.00 to 81.00 cm with an average of 47.79 cm. Fruit weight ranged from 55.0-362.0 g with average 101.92 g and yield per plant ranged from 12.53 to 126.70 kg with average 26.54 kg. The morphological dendrograph generated from agglomeration hierarchical clustering grouped the 22 genotypes into 5 major clusters. Heatmap explaining the overall performance of the genotypes indicated that BARI Peyara 2 and BARI Peyara 4 had higher yield potentiality. BARI Peyara 2, BARI Peyara 4 , PG Pah 001, PG Pah 005, PG Pah 07, PG Hat 004, PG Hat 009, PG Hat 010, PG Hat 012, PG Hat 017, PG Hat 018 and PG Hat 020 can be selected for breeding program based on their desirable qualitative and quantitative traits.</p> 2020-11-10T00:00:00+00:00 Copyright (c) 2020 Journal of Agricultural Science & Engineering Innovation (JASEI) Genetic diversity analysis of proso millet (Panicum miliaceum L.) in relation to phenotypic characters 2021-01-02T10:46:44+00:00 M. Shalim Uddin Md. Golam Azam Shamim Ara Bagum Md. Abdul Hakim <p>Genetic divergence study is very essential for the selection of genetically diverse parents from existence germplasm for conducting successful hybridization program. An investigation with one hundred nineteen genotypes of proso millet was carried out in Bangladesh Agricultural Research Institute (BARI), Gazipur, Bangladesh to study the nature and magnitude of genetic divergence following Mahalanobis D<sup>2</sup> statistics. The experiment was accompanied following Randomized Completely Block Design (RCBD) which replicated thrice. The 119 genotypes of proso millet were assembled into eight clusters. Among the eight clusters, cluster VI was found to be largest having 27 germplasm followed by cluster V having 20 germplasm. While the minimum number of germplasms was observed in cluster II noted as 7. High degree of genetic diversity was revealed by the genotypes of cluster III and cluster IV. Cluster III was appropriate for filling period, height of plant, weight of seed per panicle, yield of straw /plant and yield of grain /plant. Cluster VIII is suitable for early flowering and short duration proso millet variety. Cluster III is best suited for the development of dwarf variety. Weight of seed/ panicle (g) and flag leaf area (cm2) contributed most towards genetic diversity of proso millet. Analysis confirmed the lack of association between geographic origin and hereditary assortment, as germplasm from the unalike area clustered into same groups and the germplasm of alike area were congregated into different clusters. Therefore, plant breeder should assess their material for genetic diversity and should not purely depend on their geographical origin.</p> 2021-01-06T00:00:00+00:00 Copyright (c) 2021 Journal of Agricultural Science & Engineering Innovation (JASEI) The Perspectives of Medicinal Plants for COVID-19 Treatment: A Review 2020-11-01T18:45:10+00:00 Md. Golap Hossain Debasish Paul Md. Arfan Ali Md. Nurul Huda Md. Sarowar Alam Shreef Mahmood Bahget T. Hamooh <p>The World Health Organization (WHO) declared the COVID–19 as a pandemic disease due to its rapid spreading worldwide, caused by a novel coronavirus (SARS-CoV-2) that has caused many fatalities. Until now, no effective treatment in the form of anti-virus medication or vaccine has been available for the disease. Therefore, this review aimed to summarize some important medicinal plants with herbal formulae and guidelines which are used to treat viral disease especially pandemic disease COVID-19. Based on this argument, an online search was performed, which assisted to identify a group of plant species harboring antiviral properties. In the recent past, some natural herbal compounds prepared from existing medicinal plants available surrounding us have demonstrated encouraging antiviral properties. This review can be used as guidance of traditional medicine for the alternative treatment of COVID-19 disease with the utilization of medicinal plants. As COVID-19 has no specific treatments or vaccines in our hands, we must continue our investigation to find the most suitable treatment for this pandemic.</p> 2020-11-10T00:00:00+00:00 Copyright (c) 2020 Journal of Agricultural Science & Engineering Innovation (JASEI)
