Institutions and Agricultural Development: the case of the North West Province in South Africa

Generally spoken, agricultural development initiatives have not been translated into the upliftment of the rural poor which is primarily due to a very low level of success of these initiatives. It is believed that the institutional framework is critical in determining the success of agricultural development. In this study an institutional analysis is applied to analyse the current institutional framework revolving...

Pharmacodynamic and ethnomedicinal uses of weed speices in nilgiris, Tamilnadu State, India: A review

Generally, weeds are considered as nuisances in the garden and enemies to the farmer, as there is a misconception that they are useless. Many of the herbs used in Indian traditional medicine and tribal medicine are considered weeds by agriculturists and field botanists (for example, Phyllanthus amarus L., Eclipta alba L.,Centella asiatica (L.) etc.). Even though many of these weeds have high...

Effect of pruning on carbohydrate dynamics of herbal and medicinal plant species: Prospects leading to research on the influence of pruning on productivity and biochemical composition of bush tea (Athrixia phylicoides D.C.)

Pruning is an essential agronomic practice and it has been shown to be the most important operation, next to plucking, which directly determines the productivity and quality of tea bushes. In tea, pruning helps stimulate vegetative growth and prevent reproductive growth phase. In addition, pruning leads to enhanced branching and hence it rejuvenates the tea plants resulting in a greater number of tender leaves for...

Phytochemicals from Ficus sycomorus L. leaves act as insecticides and acaricides

Phytophagus insects cause damage and economic loss in crops. The indiscriminate application of synthetic products has led to various problems. Among all, bioactive natural compounds considered to have an activity because of the presence of several chemicals that can exert their activities both as fumigants and by direct contact. The bioactive phytochemicals from Ficus sycomorus leaves were analyzed by gas...

Ex situ conservation of Hedychium spicatum Buch.-Ham. using different types of nursery beds

Hedychium spicatum Buch.-Ham. belongs to family Zingiberaceae. It is known for its many medicinal uses. Due to great market potential of the plant, it is harvested in uncontrolled way causing the decline of the herb from its natural habitat. Presently, its status in nature is not good. Thus, there is need of its in situ as well as ex situ conservation and propagation. The present study was...

Production of deoxynivalenol by Fusarium graminearum Schwabe in culture and its toxicity to wheat germlings in relation to virulence

Seven isolates of Fusarium graminearum obtained from Seed and Plant Improvement Institute were grown on autoclaved barley grains and toxicity of their cultures to wheat germinating seeds was tested using their semi-purified phytotoxins. The extracts of isolates 167, 169, 173 and 179 did not have considerable inhibitory effects on wheat seed germination, whereas that of 161 (a = 0.05) and two other isolates 131...

Bacterial assessment and keeping quality of milk obtained from savanna brown doe

Bacterial activities of milk obtained from Savanna brown doe, were chemically assessed before and after pasteurization. A total of 60 L of milk was collected from a randomly selected doe in 10 different herds within Minna, and was stratified into 3 treatments (T1 - T3), with 5 replicates (R1 - R5), in a completely randomized design (CRD). After collection one quarter of it was homogenously pooled and...
