Field trials were conducted at the College of Education for Pure Sciences, Ibn al-Haytham, University of Baghdad Iraq, during the 2023-2024 growing season to study the effect of vermicompost and aqueous extract of Conocarpus erectus leaves on the coriander plant (Coriandrum sativum L.). The experiment involved two factors: the first with two levels of vermicompost at 0 and 5 tons ha-1, and the second by spraying the aqueous extract of conocarpus plant leaves at 0, 10, 20, and 30 g L-1 concentrations. The interaction treatment with vermicompost at 5 tons ha-1 and extract spraying at 20 g L-1 concentration produced the best results for number of leaves (51.33 leaves plant-1), leaf chlorophyll content (41.77 SPAD), dry weight of the vegetative system (13.87 g plant-1), dry weight of the root system (6.30 g plant-1), leaf area (14.533 cm2 plant-1), number of inflorescences (44.37), yield per hectare (669.21 kg ha-1), percentage of volatile oil in the coriander leaves (0.449%), and the specific gravity of oil (0.71 mg). The control treatment gave 30.67 leaves plant-1, 26.57 SPAD, and 5.83 g plant-1 1.90 g plant 1 Address for Correspondence Received: 2025-12-07 DOI: , 5.033 cm2plant-1, 19.57 inflorescences 303.07 kg ha-1, 0.213%, and 0.33 mg, respectively, for the same growth indicators. This study proved that coriander plants respond positively to vermicompost fertilizer and spraying with the aque
The olive tree, has been used it is important plant for the time being some of their parts on a large scale in the treatment of gastrointestinal disorders and stimulate circulation . Moreover, it is used as antibacterial material and also to address some of the respiratory system, diabetes, food preservation osteoporosis. This study involved the collection of olive leaves from different areas in Baghdad / Iraq. These leaves have been harvested, wash it, then dried and crushed, where the study aimed to identify the active ingredients and chemical elements in the olive leaf as well as its effect on the action of GOT enzyme .The study showed that the aqueous extracts (cold and hot) of the olive leaves powder are acidic in nature pH values
... Show MoreThe essay discusses how different environmental factors affect plant growth by explaining how each factor affects the physiological processes within the plant. The essay begins by explaining the effect of temperature on plant growth, as high or low temperatures can significantly affect the rate of photosynthesis and lead to a reduction in water and nutrient absorption. It also discusses the light intensity impacting plants because the more appropriate the light intensity is, the more enhanced the plant's photosynthesis ability, and in the excess or insufficient light condition, the growth can be inhibited. Additionally, the article outlines the effect of water shortage on the plant because this leads to the closure of stomata to avoid water
... Show MoreA field experiment was conducted during the autumn of 2021 at the Agricultural Research Department station / Abu Ghraib to evaluate the soil moisture, water potential distribution, and growth factors of maize crops under alternating and constant partial drip irrigation methods. In the experiment, two irrigation systems were used, surface drip irrigation (DI) and subsurface irrigation (SD); under each irrigation system, five irrigation methods were: conventional irrigation (CI), and 75 and 50% of the amount of water of CI of each of the alternating partial irrigation APRI75 and APRI50 and the constant partial irrigation FPRI75 and FPRI50 respectively. The results showed that the water depth for conventional irrigation (C1) was 658.3
... Show MoreA two-year study (harvest years 2019 and 2020) was conducted to investigate the effect of a commercially available biofertilizer, in combination with variable nitrogen (N) rate, on bread baking quality and agronomic traits in hard winter wheat grown in conventional (CONV) and organic (ORG) farming systems in Kentucky, USA. The hard red winter wheat cultivar ‘Vision 45’ was used with three N rates (44, 89.6 and 134.5 kg/ha as Low, Med and High, respectively) and three biofertilizer spray regimes (no spray, one spray and two sprays). All traits measured were significantly affected by the agricultural production system (CONV or ORG) and N rate, although trends in their interactions were inconsistent between years. In Y2, yield was
... Show MoreMorus alba, member of the Moraceae family, is a perennial tree utilized in folk medicine, preparing the modern drug, and considered the main food for silkworms. However, data on chemical content in the leaves is still limited; the main objective of this study is to detect the presence and determine the concentration of different polyphenolic constituents in the leaves of the Morus alba plant by reverse phase-high performance liquid chromatography (RP-HPLC) and evaluate the cytotoxic effect of ethyl acetate extract of this plant on human breast cancer (AMJ-13) cell line. Phytochemical analysis of the Morus alba leaves ethyl acetate extract led to identifying and quantification of six polyphenolic constituents designated as phenolic a
