The dried sample was pulverized using automated blender. Herbage use by grazing cattle in various densities of leafy spurge ( Euphorbia esula L. # ³ EPHES) was evaluated over a 3-yr period in North Dakota. Department of Botany, Nnamdi Azikiwe University, P.M.B. Man and, The low and erratic precipitation of desert habitats and the resultant drought have been a huge environmental challenge to the desert flora. The fact that the highest Cognitive Salience Index (CSI) scores of all wild vegetables freelisted corresponded to weeds, reinforces the assertion that weeds are culturally cognitively important for local farmers as a vegetable source. The answer lies 'in the soil' and 'in biodiversity' - but not in the way that most people suspect. In this time of growing awareness of the role of human-caused global climate change related to rising atmospheric carbon dioxide concentrations, farmers and agricultural professionals are beginning to talk about carbon sequestration as an added benefit of sustainable and organic farming. 0000003701 00000 n Among other wild plants, the weed species Portulacca oleracea and Amaranthus spp. Author CBE contributed in the first draft of the work. The Wealth of India. back to the beginning of agriculture, and they, more of hundreds of toxins from nearly major. 1990; 28:69-73. Applying herbicides at the wrong time often results in poor weed control and crop injury. However in the correct and controlled location they can be beneficial and do have economic value. [29, 30] reported that fiber have been found to protect against cancer while [31, 32] reported that a diet high in soluble fiber lowers blood level of the harmful type of cholesterol without lowering the good cholesterol level. beneficial properties, which include, but not limited to benefits of weeds to companion plants. Among. within 5 to 10 years of construction that their, more widely distributed throughout the world than, weeds to attract and provide habitat for beneficia, For example, wild umbellifers attract predatory, feed common garden pests to their offspring [6, predatory beetles, which are generally thought as, pests from their allelopathy. 1968; 57:2174-2175. References 1. To minimize the negative effects of poisonous plants in pastures, it is necessary to know the reasons for the spread of poisonous plants in grassland, their poison levels and conditions under which they affect livestock. The readings were recorded and later plotted into a standard curve used to extrapolate the K level in the sample. The oilseed radish cover crop was sown in five treatments plus an untreated control over a period of five weeks before and three weeks after winter wheat harvest. It seems that some of these plants could potentially serve as models for understanding drought adaptation mechanisms and their potential uses. Moreover, the ecological consequences of landscape disturbance and landscape fragmentation are reviewed. 36 of these plants are considered weeds [66].

The ammonium sulphate (NH4)2SO4 thus obtained was boiled with excess of 60% NaOH solution (11-16 ml) to liberate NH3 gas which was passed through in a conical flask containing 10 ml of 2 % H3BO3 solution until 20-40 ml of distillate was collected (about 15 minutes). The root had higher acid insoluble and water soluble ash (0.38±0.01), (2.38±0.01) respectively. Studies in the proximate analysis of leaves of Catharanthus roseus. %%EOF Out of 2, 50,000 plant species, weeds constitute about 250 species, which are prominent in agricultural and nonagricultural system. Gajalakshmi S, Vijayalakshmi S, Devi Rajeswari V. Pharmacological activities of Catharanthus roseus, a prospective review. leave, stem and root showed good values. If weeds are allowed to grow for an extended period crop yield may be drastically reduced. High plants are sources of drug which have made important contribution to the welfare and quality of life urban as well as rural communities especially in tropics and sub-tropics [3]. J Pharm. After digestion, it was dried at 110 0C for 12 hours ignite at 550 0C in a muffle furnace for 8 hours and recorded the loss of weight [22]. 1976, 40-100. This concern underlies the mounting questions about the profitability, long-term efficacy, and environmental safety of the discipline’s historical focus: herbicidal management of weeds (i.e., “plants out of place”). It was used as folk remedy for diabetes in Europe for centuries [11]. Chondrilla juncea. More often than not, however, successful weed control requires the combination or sequential use of several methods (called integrated weed … similarly the same volume of standard phosphorus solution as well as standard and blank respectively. 0000020442 00000 n Also, the stem had the highest calcium content (159.3±0.016) and the least calcium content was found in the leaf (122.9±0.021).

United States of Pharmacopeia United States of Pharmacopea national Formulary USP30-NF25.   Efforts to control it through manual, mechanical, chemical and biological means have met with little success. It is expected that understanding the response of plants to increasing drought would be important in the light of global and regional climate changes, not only to forecast population dynamics in natural ecosystems but also to adjust management processes in agronomy and vegetation management for improvement. Abstract Proximate and mineral composition of leave, stem and root of Catharanthus roseus was studied. Siam weed was introduced to Nigeria in 1937, through importation of timber species from Sri Lanka. A similar procedure was followed in the blank determination. These areas are the natural resources for the cheapest providing of the roughages needed by animals. European Journal of Biotechnology and Bioscience  13. 2.3.7 Carbohydrate Content Carbohydrate content of leaves and flowers of C. roseus was estimated by subtracting the sum of the protein, fat, ash and crude fiber from the dry sample. Nevertheless, there is a high potential of early sown oilseed radish for higher weed control efficacy, which was demonstrated in 2016. Phosphorus was highest in the root (312.1±0.025) and lowest in the leaf (252.2±0.023). It is also used for the regulation of menstrual cycles, and as a euphoriant [7]. A weed is a plant considered undesirable in a particular situation, "a plant in the wrong place". Today’s weed researchers Also, the stem had the highest calcium content (159.3±0.016) and the least calcium content was found in the leaf (122.9±0.021). 14. The gas and air lets were opened as the start knob was turned on. The percentage of crude fiber was calculated by become weeds if they are repeatedly reintroduced, or can survive by their perennial habit and vegetative spread (Walia, 2003). Official method 2.055-2.058. Carbohydrates are the most abundant of the four classes of biomolecules. Weed? Annual plants complete their life cycle (from seed to Dry matter (%) = 100 - % moisture.

The results supported ethno botanical uses of Catharanthus roseus as medicine and potentials of the parts as source of food. It is well known that physiological changes do occur in plants due to changes in geographical sites, climatic and environmental conditions which result in the production of non-identical plant metabolites in the plant grown in different 1995; 65:1-618.

It is one of the chief herbs for treating dermatitis, abscesses, eczema, psoriasis, sores, corns, ringworm, scabies, epilapsy, malaria, heart tonics and tumor. Nature has bestowed on us a very rich botanical wealth and a large number of diverse types of plants grown in different parts of the country [1]. Weeds provide a vegetative cover that protects the soil surface against erosive action of rain and wind. 35  J of Natural Product Research.

Trends in Applied Science and Research. While losses in animals such as death, weight loss, abortion, decreased reproductive efficiency, birth defect, decreased productivity are described as direct losses, feed losses arising from additional feed supply, treatment costs, regulation of management and efforts to reduce animal poisoning by plants are referred to as indirect losses. Lioydia. But their menace is often ignored because they lack publicity of sudden outbreaks, as is commonly exhibited by several plant diseases and insect pests.

Their presence in and around agricultural land results in severe losses. All these adaptations and more, play an important role in the organisms’ ability to conquer the harsh conditions of desert environments amidst the prevailing climate changes. Because these organisms must harmonize their structures and functions to thrive in their environments, they have evolved a range of strategies to survive the drought that characterizes the desert ecosystem. 3.
