The aim of this study was to evaluate and compare the floristic diversity, phytosociological spectra and geographical characteristics of the understorey of the old abandoned plantation of the Yangambi Biosphere Reserve, using the Martineau and Blanc-étoc silvicultural methods. This was done to fill gaps in our knowledge of the latter. The experimental setup consisted of 50*50 m (Martineau method, 2023) and 50*50 m (Blanc-étoc, 2023).  All undergrowth species with a diameter of 5.0 cm or greater were inventoried using Letouzey's [1] established technique. Technical abbreviations were clear ..read more

High ammonia levels in enclosed fish production systems negatively impact fish growth and hinder optimum production. The objective of this study was to evaluate the (i) biofiltration potential of chia (Salvia hispanica) and lemon grass (Cymbopogon citratus) (ii) the influence of the plant filters on water quality and fish growth in an aquaponic system. Treatments included a control-without plants, S. hispanica, and C. citratus aquaponic systems. The study was conducted for 3 months in Aqualife fish farm, Machakos, Kenya. Water quality parameters, growth performance of fish and plants were moni ..read more

Pear is a tree belonging to the Rosaceae family, sensitive to different environmental conditions. It is spread in East and West Asia, America and the European Union, and its production has an economic role for many countries of the world, including Palestine. Average annual temperatures and precipitation were analyzed using data from the Palestinian Meteorological Station affiliated with the city of Jerusalem, which was recorded between the years (1993-2014), and equal to the number of years of pear production, noting that the data for pear production was taken from the Palestinian Central Bur ..read more

Aims: To discover the resistance of the Yemeni genotype of fenugreek to salt stress and the impact of salicylic acid on alleviating salt stress. Study Design: The experimental design adopted a completely randomized block design (RCBD), with pots filled with a 1:2 mixture of sand and soil serving as the experimental units. Place and Duration of Study: in a mini greenhouse covered with white polyethylene plastic sheet at Taiz University during the spring season 2021. The average temperature ranged from 32 ℃ during the day to 29 ℃ at night. chemical analyses were performed at the pharmaceutical l ..read more

Present day healthy food is very important but farmers and market people are using more chemicals so that total recourses are polluted. Mainly farmers using more chemical fertilizer so that it is affected to soil, resource, human health, animals and plants. These all are polluted due to inorganic farming. The main objective of the study is to reduce chemical fertilizers for growing yields and also not use chemicals in marketing. So, that reduces diseases like cancer, heart attack, stroke and many other type of diseases. Improvement of organic yields is very important in that way to involve gov ..read more

Vertical farming has the capability to produce the food or any other services in urban areas which are related to it. The goals and vision of vertical farming is planned with the aim of generating sustainable cities around the world. The recent traditional farming approaches due to an imbalance in the environment. At the end it appears that the concept of the vertical farm in the city centre of urban area could solve various issues that is related to food production and environmental degradation. No crop harvests would fail by severe weather like droughts, floods and hurricanes etc. Hence the ..read more

The aim of this study is to determine the presence of Ulva seaweeds, possibly by analyzing the quality of seaweed powder extracts and some organic solvents. It belongs to the order Ulvaales. Ulva lactuca is a widespread macro algae growing the Mediterranean coast phylum Chlorophyta, commonly known as “sea lettuce”. Collected from the Gulf of Mannar Tamil Nadu, India. Dry the Ulva seaweeds and grind it in a food processor until it becomes a fine powder. The powder is dried in an oven at 600c for 24 hours. Alkaloids, Flavonoids, Saponins and Tannins. dried seaweed nutrients rich in energy 252.72 ..read more

Slope gradient is a critical environment factor influencing the abundance, distribution and diversity of vegetation. The objective of this study was to exploring the influence of slope gradient on tree species richness and forest structure in Kpatawee forest, Liberia. Tree diameter was measured at breast height for species more than 5 cm in diameter and over 3 m in height. Tree species diversity was analyzed using Shannon diversity index (Hˈ). Basal area (BA) which is the cross-sectional area of tree stems was measured through the diameter at breast height that is 1.3 m above ground level. Res ..read more

Weather instability affects nematode proliferation in soil, affecting plant growth. Identifying endemic species and favourable seasons can guide farmers in cultivating crops during specific seasons, minimizing infections and improving yield. A survey to evaluate the influence of seasonal disparity on plant parasitic nematodes population in soil and roots of bell pepper (Capsicum annuum L.) was carried out during dry and rainy seasons in Otari, Abua/Odual Local Government Area of Rivers State, Nigeria. Five bell pepper cultivated fields were randomly selected and a total of 300 soil sample ..read more
