Radish (Raphanus sativus L. ssp. sativus or Raphanus sativus L.) belongs to the genus Raphanus and the family Brassicaceae (Crucifereae). It is a diploid species with chromosome numbers 2n = 2x = 18. The genus Raphanus originated from coastal regions along the Mediterranean and Black Seas. Most scholars believe that cultivated radish (R. sativus L.) was originated from wild radish (Raphanus raphanistrum L.) while others thought R. sativus was derived by the hybridization between R. maritimus and R. landra. Other names of radish are wild radish, garden radish, daikon.

The main objective of this article is to analyze the actions of the Sweet Water Program – PAD in the development of the Brazilian semi-arid region. Initiatives such as the Sweet Water Program, which promote the sustainable use of water, directly contribute to combating the effects of climate change. It is an effort by the government to internalize such concerns, disseminating good practices in the sustainable use of water. This isanexploratory, descriptivestudywith a qualitative approach, bibliographical and documentary.

Cucumber belongs to the Family Cucurbitaceae, Subfamily Cucurbitoideae, Tribe Melothrieae, Subtribe Cucumerinae, Genus Cucumis and Species Cucumis sativus L. The Common Names of Cucumber are garden cucumber, apple cucumber, gherkin and khira. Cucumber (Cucumis sativus L. 2n = 2x = 14) is one of the Asiatic species. Cultivated for at least 3,000 years, the cucumber originated from India, where a great many varieties have been observed, along with its closest living relative, Cucumis hystrix. It was probably introduced to Europe by the Greeks or Romans.

Plant secondary metabolites (PSMs) are plant products that are variously distributed throughout the plant kingdom. These secondary compounds have various chemical groups and are named according to their chemical constituents. For their ability to defend biotic and abiotic stresses they are considered as plants' defensive or bio-functional compounds. These metabolites derived from secondary metabolism of plants are produced for protection of the species from insects, herbivores and extreme environmental conditions. They are indirectly involved in plants’ growth and development.

Growth performance of five marine microalgae Isochrysis galbana, Chaetoceros calcitrans, Tetraselmis suecica, Nannochloropsis oculata, Aphanocapsa species was studied under different culture conditions i.e. Conway and f/2 media at 20, 30 and 40ppt salinities (‰). The microalgae culture was undertaken in the indoor facility with 24±1° C temperature, PH 8.7±1 under 24hour photoperiod. Overall highest cell density (56.23million cells/ml) was recorded in Aphanocapsa sp. in Conway medium at 30‰ followed by N.

Coming from the Latin acrumen which means sour, the word citrus was given in antiquity to trees with acid fruits. Indeed, citrus fruits refer to several species, the best known of which are oranges, grapefruits, mandarins, clementines and lemons. Species of the genus Citrus are well known but very little studied in Niger. It is with the aim of providing more data that the present study was carried out. The general objective was to study the ability to propagate by cuttings in three citrus species (Citrus limon, Citrus tangelo and Citrus sinensis).

Dye yielding plant species survey of Vijayapur district of Karnataka comprising 13 tehsil was conducted during March 2018 to November 2022. The purpose of this survey was to document the dye yielding plant species. The present study was initiated with an aim to identify dye yielding plant species resources from elder people, shepherds, and formers of Vijayapur district. There are about 35 species of angiosperms belonging to 35 genera and 26 families of dye yielding plant species were found.

Este trabalho discute as potencialidades de desenvolvimento via extensão universitária no ensino superior no Brasil. A partir de uma narrativa autobiográfica, a professora revisita sua atuação em sala de aula junto a um componente curricular que promove uma ação de extensão universitária no curso de Arquitetura e Urbanismo da Universidade São Francisco.

Soil is a fundamental resource for man’s life on earth, most of the goods he needs coming directly or indirectly from the soil. This is not done without compensation in favour of the soil, which loses its productive capacity over time. Compensation is made through the provision of both mineral and organic fertilizers to the soil. A trial was conducted in Ngandajika where it was applied to the soil, two organic fertilizers, Bat-guano and Tithonia diversifolia, a mineral fertilizer, DAP for growing corn.

Producing progeny is a natural gift given by the mother nature to the living organism, and it is an important part of human life as well. Therefore, infertility is viewed as a highly physical and emotional problem in Indian society.About half of infertility cases are caused by male factors. Approximately 35% of infertile men are due to oligospermia. There is no promising cure for this disease, but Ayurvedic preparations often show significant improvements in semen parameters. Oligospermia can be corelated with the Ksheenshukra entity in the Ayurvedic literature.
