Vinegar is a non- selective contact herbicide. In general, weed control increase as acetic acid content and application volume increase for example 20, 40, 80 and 100 gpa. Typically, vinegar is less effective in controlling grasses than broadleaf weeds and more effective on annual species than perennials. In addition to application volumes and concentration, weed control is also dependent on the weed size and the species. Repeated application of acetic acid may be necessary for satisfactory weed control.
The panicles arise from the top of the plant along the stem. Also, the seeds are about two millimeters in diameter and of various colors. This crop would be a grain but it does not come from the grass like wheat, oats or barley (Raffael, 2012). This crop is well adapted to extreme environmental conditions and is also an important food source for human consumption. The seeds of quinoa (Chenopodium quinoa) are nutritionally important because they have high protein content.
Verdc.) seeds is an easy to cultivate legume seed which is widely grown throughout tropical Africa, Indonesia, Malaysia, India, Sri Lanka, Central and South America and some parts of Northern Australia (Eltayeb et al., 2011). Bambara groundnut originated in West Africa with its name derived from the Bambara tribe who now lives in Mali (Nwanna et al., 2005). Considered as one of the main attributes of Bambara groundnut is its tolerance of poor soils and drought, as well as its ability to yield in conditions in which groundnut fails completely. Bambara groundnut which is primarily grown for its edible seeds are lower in oil content compared to groundnuts, but higher in protein and carbohydrates.
Bambara groundnut is an underutilised crop predominantly grown in African countries [19,20] and is mainly cultivated in Sub-Saharan Africa's warm tropics . Bambara groundnut is very nutritious, having 65% carbohydrate content and 18% protein . The need for locally sourced raw material for pharmaceutical manufacturing is critical as it lowers manufacturing costs, creates jobs in multiple areas like planting, harvesting, and crop storage . A previous study  investigated the heat stability and pasting properties of the native and modified starches, however the objective of the present study was to investigate the compression, mechanical and release properties of thermal and chemically modified starches from Bambara nut in Ibuprofen tablet formulations as directly compressible and sustained release excipients. Ibuprofen was chosen as the model drug for this study because of it known poor compaction properties , in order to assess the influence of the starch-based excipients on the formed tablets.
(2009) also observed highest plant height, number of branches, number of umbels, dry weight and fruit yield per plant of coriander with the treatment combination of Azospirillum + 50 % N. Bio-fertilizers add nutrients through the natural processes of nitrogen fixation and stimulating plant growth through synthesis of growth promoting substances and might have positively influenced the crop yield. The beneficial role of supplemented organic manures and bio-fertilizers in improving soil physical, chemical and biological role is well known, which in turn helps in better nutrient absorption by plants and resulting higher
1.1 Traditional Medicine Humans owe their continued survival largely to the existence of plants for their general livelihood and most essentially medicinal use. Knowledge as to which plants are more useful than the other has been passed on from one generation to the next (Weiner and Weiner, 1994). According to Simpson and Orgorzaly (1995), applications of various plants in different parts of the world vary amongst cultural groups, as plants are distributed quite differently across countries. In South Africa, a number of plant species with medicinal properties are considered to be vital in the treatment of ailments which has been a common practice in rural areas (Masika et al., 2000). Globally, numerous people depend on herbal medication as
(Huang, 2014) Another good binder is gum Arabic or acacia gum which is harvested from acacia tree. Acacia tree is very common in semi arid areas especially in Africa Sahel and in particular Senegal, Sudan, Somalia, etc. A kilogram of high quality gum Arabic is costing $2 ex-works in Kenya. If you are to use 5% gum Arabic for your charcoal briquettes, then, this is not cheap either. Mashed newsprint/waste paper pulp is also a good binder.
The section described some species of medicinal plant from various families that have been investigates for anti – dengue activity. Herbal medicines play a major role in treatment of many diseases in humans and animals. Nowadays these medicinal plants have emerged as a unique approach to safe, effective and inexpensive new remedies for variety of diseases as they do not have adverse effects. Many natural drugs isolated from plants were showed good antiviral activity against Aedes aegypti mosquito. LNCP Page 8 Design and development of antidengue capsule Several investigations were carried out on different plant extracts and few of them showed anti viral activity on dengue virus.
Yearly yield ranges from around 10 to 25t/ha (Norman et al., 2002). Production of Sweet pepper in Ghana is fundamentally under downpour sustained conditions bringing about a drop in supply particularly amid the dry seasons. In Ghana, Efutu municipal is noted to be one of the leading areas for sweet pepper production. Sweet pepper production is a good source of income generation for farmers (Bonsu et al., 2003). Sweet pepper is a vegetable making positive impact at the local and export markets causing an increase in its commercial value.
Millet are small and mostly round in shape and comes in different colors but mostly, white, yellow, red etc. they are known to be grown wildly in Africa, Asia and some European countries. As compared to many other cereal crops, millet is known to grow very fast and can survive harsh conditions which includes less rainfall. This indicates that, millet crops can survive in dry and cold areas. However, millets are known to be highly nutritious
