In this study, three genotypes of tomato (Cobra, Roma vf, and Tropimech) were subjected to induced mutation with ethyl methane sulfonate (EMS). The result in the M2 generation was analyzed and traits assessed showed significant different (P < 0.05) among the variants of genotypes of tomato species studied. Cobra and Roma vf genotypes produced lots of mutants of interest. Cobra variant 2 (CV2) had the highest fruit weight of 2.796kg with a total of 36.7 number of harvested fruits per plant. Variant 3 had a fruit weight per plant of 2.178kg and it produced the highest number of harvested fruits per plant of 43. Other relatively performed variants of cobra include, variant 7 with the fruit weight of 1.7131kg and 28.3 number of harvested fruits. Variant 8 recorded a fruit weight per plant of 1.474kg with 30.3 number of harvested fruits. Variants 5 and 4 equally performed well with their fruit weights of 1.254kg and 1.232kg and number of harvested fruits of 29 and 19.7 respectively. In Roma vf, the highest fruit weight per plant of 1.2094kg was recorded by variant 8 with 69 harvested fruits per plant. This variant produced lots of fruits with a creeping growth habit that makes it behave like the indeterminate variety. Variant 2 recorded 1.11613kg with 25.33 of harvested fruits giving an average fruit weight of 44.06g. The M2 generation of Tropimech variety (TV) varied significantly in values recorded for the variants with TV3 recording highest fruit weight per plant of 368.47g.

Escalating population pressures and its effect on food security has led to use of costly fertilizer intensive agriculture is trying to cope with the increasing demand. This in turn is causing drastic deterioration of the ecosystems and climate. Therefore, it is time to consider alternate ways to overcome the wide- spread use of chemical fertilizers and improve productivity to shorten the gap between production and demand. This review paper provides in-depth perspective of the challenges in agricultural value chain, probable solutions, both biological and digital, alternate farming practices fortified with algae to increase productivity and uses of microalgae and their benefits to both soil health, increase in productivity, as fertilizer, in pest control and as growth regulator for crops.

Phytoplankton are organisms that are sensitive to environmental changes and their presence can be used as an indicator of aquatic productivity. Physical factors in the waters can affect the abundance of phytoplankton. The purpose of this study is to determine the relationship between physical factors (temperature, brightness, TDS and TSS) and the abundance of phytoplankton. Phytoplankton sampling was carried out at 7 stations by purposive random sampling in Menjer Lake including 7 sites of the tourism areas, floating net cages, near agricultural areas, the middle of the lake, spring sources, inlets of the Serayu River and outlet areas. The variables measured were temperature, light penetration, TSS and TDS concentration as well as the composition and abundance of phytoplankton. The results of this study obtained 6 species of phytoplankton, namely Ceratium sp., Dictyosphaerium pulchellum, Microcystis aeruginosa, Microspora sp., Nitzschia sp., and Pediastrum sp. The highest abundance of phytoplankton is Microcystis aeruginosa and temperature in related to season has a strong effect on the abundance of phytoplankton.

Anemia is a serious health condition in Sub Saharan Africa (SSA). The region is vulnerable to multiple underlying causes of anaemia that are many and varied. It affects children under five years, nonpregnant women, pregnant women and the elderly. Many interventions that include nutritional food fortification and infection control programmm through malaria infection control and many other infection control programs were designed in order to reduce the prevalency of anemia in SSAcountries but low success was acheived due to so many varied factors. So in this review we discussed on the major causes of anemia, risk factors, diagnostic challenges and management of anemia in SSA.countries. The methodology used was to review previous literatures on the subjects.

Some factors hastening up retting process which are- retting water, retting in already used water, harvesting time, climate conditions like high temperatures, deep water (too deep water will delay retting, addition of chemicals, materials used as weights on Jak, method of retting, variety of jute, method of fiber extraction, stage of harvesting, period of retting, etc. There are few methods of retting available which are- conventional method of whole plant retting, chemical retting, microbial retting, mechano-microbial retting and In-situ retting with microbial consortium. There are three sequential stages in retting (based on the morphological modification, dynamics of pH and various enzymes related to them during the entire jute retting process): Stage 1 (Initial retting stage); Stage 2 (Middle retting stage) and Stage 3 (Final retting stage).

Raman was first discovered by C.V. Raman and K.F. Krishnan in 1928.It is a spectroscopic technique based on inelastic scattering of monochromatic light usually- from a laser in the visible or near infra-red part of electromagnetic spectrum. It probes vibrational, modes of the molecule and crystals of solid, liquid, and gaseous samples. t is commonly used in chemical analysis to provide a fingerprint by which molecules can be identified. At the time of its discovery from observing sunlight, obvious challenges were posed by the lack of a good Raman source, lack of a good detector, and by interference from fluorescence, which in some cases overwhelmed the Raman signal. The advent of laser made good for the deficiency of a good Raman source, multichannel detectors like Photodiode Arrays (PDA) or Charge - Coupled Devices (CCD) for a good detector and Fourier –transform for fluorescence. In addition, instruments such as notch filters, tunable filters, laser stop apertures, double and triple spectrometric systems are now used to reduce Rayleigh scattering and obtain high-quality Raman spectra. Thus, Raman has become the optimal technique for versatile, minimally invasive spectroscopy.

As the SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) pandemic enters its third year, physicians are increasingly confronted with a new pathology, Post-COVID Syndrome (PCS). One of the common manifestations of PCS is a musculoskeletal symptom complex, manifested by myalgia, arthralgia, and arthritis. Today, there is no universally accepted term, definition, classification, diagnostic criteria, or consensus on the duration of PCS. In the literature there are enough descriptions of cases of the occurrence of rheumatoid arthritis (RA) after SARS-CoV-2. The question arises: is this a coincidence or could COVID-19 (coronavirus disease 2019) be a trigger factor for RA? From the perspective already expressed in medical circles, COVID-19 can unmask previously undiagnosed RA or cause disease de novo. In addition, the onset of arthritis can be a manifestation of PCS and can be transient. The trigger role of a SARS-CoV-2 infection in the occurrence of RA seems likely. The emergence of arthritis in the post-COVID period may pose problems in the differential diagnosis of joint damage.

Chromolaena odorata, Euphorbia heterophylla, Fleischmannia microstemon, Porophyllum ruderale and Synedrella nodiflora are five invasive plants in agrosystems in Côte d'Ivoire. They strongly influence the structure and diversity of native plant communities. In addition, they can compete for water and nutritional resources with cultivated plants, leading to a decrease in agricultural yield. This competition often occurs through the emission of allelochemicals that prevent seed germination or inhibit the development of other species. Thus, this study aims to assess the allelopathic effects of these five species on maize and rice, two crops generally used in food self-sufficiency programmes. To this end, the seed germination, root and stem growth of these crops watered with different leaf extracts of these five species were monitored in the laboratory. All five species were found to have allelopathic effects on maize and rice development. However, the action of the allelochemicals is specific to the target plant organs and increases with the concentration of the extracts. The study shows that of the five plants, C. odorata, E. heterophylla and F. microstemon are the most damaging as they have a more pronounced effect on seed germination.

This study aims to see the effect of differences in light illumination on the growth pattern of seed catfish (Pangasius sp). The experimental design used in this study was a completely randomized design (RAL) with 4 light illumination treatments and 3 replications. The parameters measured in this study were the daily growth rate and growth pattern of seed catfish. The difference in light illumination tested in the study had an influence on the daily growth rate of seed catfish (Pangasius sp). with the best treatment in this study from treatment A namely by providing light illumination of 11 lx provides the best daily growth rate of 5,9 % and continues to increase every week. The growth pattern of the length and weight of a relationship is negative allometric where the value (b) and the determinant coefficient value is lower than 3 which means that the growth of fish seed length affects the body weight gain of seed catfish.
