A survey was carried out to evaluate the potentials of Moringa oleifera (Lam) within and outside the Kano metropolis of Kano state, Nigeria, where it serves as vegetable and hedgerow plant for diet supplements and multipurpose utilizations. Structured interview was used with a total of 100 respondents, randomly spread. In the Kano metropolis, which falls within the Kano city, 4 Local Government Areas (LGAs) were covered. These are: Nassarawa, Ungogo, Tarauni and Dala; while Madobi, Minjiibir, Garun Mallam and Dambatta LGAs were covered outside the Kano metropolis. Results of the structured interview using the Convenience Sampling Technique revealed that Moringa is very rich nutritionally, economically and medicinally. Moringa utilization cuts across various categories of people with 69% usage recorded for male and 40% for literate users, while students and civil servants had 21% each. Moringa farmers that cultivates simultaneously on farmlands and backyard gardens were however 73%. Analysis of results further indicated that the plant is rated very high as diet supplements in the state, owing to the fact that it is very rich nutritionally, apart from its economic and medicinal values. It is however recommended that its nursery propagation be encouraged, and community interest in its cultivation mobilized.

Bionts isolated from thalli of Cladonia verticillaris, immobilized in calcium alginate, produce two depsidones, fumarprotocetraric and protocetraric acids, and the depside atranorin, that exhibit antimicrobial activity against Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae. Organic lichen extract (acetone/ether/chloroform) shows the highest antimicrobial activity due to a possible synergism between these substances. Antioxidant capacity of soluble metabolites secreted from the immobilisates to the bath medium of incubation during the first 12 days of immobilization has been found (˃80% oxidation inhibition). The concentration of soluble phenolic substances depends on the immobilization time (during 32 days), exogenous supply of acetate (1.0m mM sodium or calcium acetate) and on the type of isolated biont (phycobionts, mycobionts, whole thallus or immobilized phycobionts co-incubated with the mycobionts ones). The role of phycobionts in phenol production has been interpreted as a possible modification of the polymalonyl pathway; for example, atranorin is actively produced and secreted during immobilization while it is not detected in thallus in natura. Co-incubated bionts secrete higher amounts of atranorin to the media during the first 12 days of immobilization. Immobilization of isolated bionts could be used as a biotechnological technique to obtain a potential source of biological active compounds. On the other hand, the physiological state detected of C. verticillaris in the Cerrado is much better for experimentation than that of the specimens collected in Caatinga since, in this case, the thalli showed the fragility that the extreme environmental conditions of the semi-arid region of NE Brazil impose on this lichen species. To date, no priority has been defined for lichen conservation in Brazilian ecosystems. It is therefore suggested that it imust important to include lichen ecophysiology studies in public conservation policies.

In various areas of Ethiopia, different plant species have been reported having a medicinal role for ailment tonsillitis. However, the ethnomedicinal information on those medicinal plant species that cure the ailment is not summarized in a way that gives general information and initiates further study. Therefore, the objective of this review paper was to summarize the ethnomedicinal information about medicinal plant species that used to treat tonsillitis in Ethiopia. The result of the review indicated that herbs and leaves are the most utilized growth forms and part of the plants respectively during remedy preparation for the ailment tonsillitis in Ethiopia. Similarly, fresh plant materials, and water are the most applied condition of plant parts and diluent added correspondingly. Chewing and oral route of application are the most widely used methods of remedy preparation and administration correspondingly, for the ailment in the country. Utilization of herbs and leaves can be seen as an advantage from the conservation point of view of medicinal plant species that used to treat the ailment since herbs can be cultivated when they are in short supply and are also available as compared to other growth forms. Similarly, use of leaves can reduce damage to the medicinal plant species as compared to the use of other plant parts such as roots. However, the utilization of fresh materials should be reduced as much as possible. Rhamnus prinoides L'Her. and Zingiber officinale Roscoe are the most commonly used medicinal plant species for the ailment in Ethiopia.

Overyielding is a common phenomenon. Overyielding of dominant grasses when in competition with common forbs during grassland restoration could lead to lower plant diversity. My objective was to characterize overyielding of Andropogon gerardii in competition with fcommon forbs. I collected soils representing different stages of restoration (0, 4, and 16 years restored) and conducted a pairwise competition experiment with a dominant grass, Andropogon gerardii, in competition with four subordinate forbs (Oligoneuron rigidum L., Liatris punctata Hook, Lespedeza capitata Michx., or Desmanthus illinoensis Michx.). Relative yield indices (RY) were calculated by comparison with a two-individual monoculture of A. gerardii with both per grass biomass and per grass net absolute tiller appearance rate (TAR). Overyielding of A. gerardii was in competition with Oligoneuron rigidum was indicated by RY values (greater than1) using both biomass and TAR measurements. These findings suggest that O. rigidum should be given low priority for inclusion in tallgrass prairie restoration seed mixes.

A yellow callus strain was established from hypocotyls of a halophilic mangrove plant, Avicennia alba, by subculture in the dark. Allelopathic activities of yellow A. alba callus were assayed using recipient lettuce protoplasts at three growth stages by the protoplast co-culture method with digital image analysis. The protoplast cultures of yellow A. alba callus were halophilic to NaCl, KCl, and MgCl2 (up to 200 mM) but not to CaCl2. By contrast, NaCl and KCl inhibited the growth of non-salt-tolerant lettuce protoplasts, while CaCl2 and MgCl2 stimulated their growth at low concentrations. Highly salt-tolerant or halophilic mangrove plant cells were expected to have low allelopathic activity, but the protoplasts of yellow A. alba callus had very strong allelopathic activity. The inhibition was strongest at the cell division stage with growth being inhibited to 50% and 9% of the control by 104 mL-1 and 5 × 104 mL-1 of A. alba, respectively. There was less inhibition at the yellow pigment accumulation stage of lettuce. Stimulation was observed at the early cell wall formation stage with up to 105 mL-1 of A. alba. The yellow pigment of yellow A. alba callus was extracted with hexane and its absorption spectrum showed the wavelength peaks of a carotenoid, neoxanthin. Using transmission electron microscopy, specific electron-dense structures were found in yellow A. alba callus, which were similar to the undeveloped ultrastructure of a carotenoid. A carotenoid was strongly suggested to be the putative allelochemical in yellow callus of A. alba.

There is dearth of information pertaining to hydroponics production of zucchini in the Kingdom of Eswatini. The objective of this study was to determine the effects of hydroponics systems on growth, yield and nutritional content of zucchini. The research was conducted in three greenhouses of the Horticulture Department, Faculty of Agriculture, Luyengo Campus at the University of Eswatini between July and October 2018. The experiment was laid out in a split-plot design replicated four times. Three hydroponics systems were used as the main plots, i.e. elevated tray, ground lay bed and Nutrient Film Technique (NFT) systems. The sub-plots were allocated to the three varieties, i.e., Amanda, Hygreen and Terminator. The zucchini grown in elevated tray hydroponics system had the highest yield in all the varieties compared to the other hydroponics systems. The results showed that there were significant differences in the growth, yield and nutritional content of zucchini cultivars grown in the different hydroponics systems. The tallest plants (26.1cm) were obtained in cultivar Terminator grown in the elevated tray system and the highest number of leaves (15) was obtained in cultivar Terminator grown in the elevated tray system. Cultivar Terminator grown in the elevated tray system had the highest total yield (15.8 tons/ha) while Hygreen plants produced in the NFT system recorded the lowest total yield (1.04 tons/ha). There were no significant differences in the iron content of zucchini among the cultivars grown in the different hydroponics systems. The results of this study revealed that different zucchini cultivars responded differently when grown in the different hydroponics systems. Therefore based on the results of this study it is recommended that Terminator zucchini cultivar can be produced in the elevated tray hydroponics system.

Conservation agriculture is a concept for resource-saving agricultural crop production system that serves to achieve acceptable profits and sustaining production while conserving the environment. The popularity of zucchini also known as baby marrow in the Kingdom of Eswatini has increased in recent years specifically for its economic value in the foreign market. This study was carried out at Malkerns Research Station, Malkerns in the Middleveld of the Kingdom of Eswatini to assess the effectiveness of different tillage methods and cultivars on growth, yield and quality of zucchini. The tillage methods used were zero, basin and mulch tillage. Furrow tillage was used as a control. The results showed that tillage methods had significant (P<0.05) differences in growth and yield of zucchini. Minimum tillage plants exhibited lowest number of leaves (9.5), vine length (36.4 cm), leaf area index (2.5) and number of flowers (6), number of fruits (1.3) and marketable yield/plant (4.6 ton/ha). Non-significant (P>0.05) differences were obtained from plants grown under basin, mulch and furrow tillage. The highest vine length (69.6cm), leaf number (17.0), LAI (3.6), and marketable yield (15.7 ton/ha) were obtained in zucchini plants grown under basin tillage system. However, there were no significant (P>0.05) differences in accumulation in leaves of zucchini plants of mineral content. In terms of the cultivars there were no significant (P>0.05) differences in vegetative growth. Star 8023 showed superiority in terms of number of fruits and marketable yield. It was observed that minimum tillage was less suitable in zucchini production as compared to other tillage systems. For higher production in zucchini, basin, furrow and mulch may be used. The best cultivar to use is star 8023.
节约型农业是指在保护环境的同时实现可接受的利润和持续生产的资源节约型农业作物生产系统。近年来，西葫芦在斯瓦蒂尼王国的受欢迎程度有所增加，特别是因为它在国外市场上的经济价值。本研究在斯威士兰王国中部马尔克恩斯马尔克恩斯研究站进行，旨在评估不同耕作方式和品种对西葫芦生长、产量和品质的影响。耕作方式为零耕作、盆耕作和覆盖耕作。以垄作作对照。结果表明:盆耕、地膜和沟耕三种耕作方式对土壤养分的影响差异显著(P0.05)。流域耕作西葫芦植株的藤长(69.6cm)、叶数(17.0)、叶面积指数(3.6)和适销产量(15.7 t / hm2)最高。而矿质元素在西葫芦植株叶片中的积累量差异不显著(P>0.05)。各品种间营养生长差异不显著(P>0.05)。星8023在果实数量和市场产量方面表现出优势。与其他耕作制度相比，最小耕作制度不适合西葫芦生产。为了提高西葫芦的产量，可以采用盆、沟和地膜。最好的品种是星8023。
