Six fungal isolates were selected from the rhizosphere of black pepper (Piper nigrum L.) plants and were tested in vitro for their plant growth promoting (PGP) abilities in the soil. The species of Aspergillus selected were tested for the siderophore production, indole acetic acid (IAA) production, catalase enzyme activity and biological control of pathogens through antagonism. The results indi...

The work reported herein describes the synthesis and the assessment of the trypanocidal activity of thirteen new 1,2,4-triazole-3-thiones obtained from natural piperine, the main constituent of the dry fruits of Piper nigrum. It is part of a research program aiming to use abundant and easily available natural products as starting materials for the design and synthesis of new molecules potential...

A study was conducted to identify the effect of arbuscular mycorrhizal fungi AMF (Funneliformis mosseae) infection on growth of black pepper (Piper nigrum Linn.) rooted cuttings. This experiment comprised of three inoculum rates (75g, 100g, and 150g of sorghum root-soil mixture containing Funneliformis mosseae) per 2kg of soil as well as two cultivars namely Panniyur-1 and GK49. Shoot and root ...

An extract of nishyinda (Vitex negundo) leaves, black pepper (Piper nigrum) and cinnamon (Cinnamomum verum) (polyherbal extract) were used as growth promoter in broilers. A total of 20 day-old broiler chicks were purchased and after seven days of acclimatization randomly divided into two equal groups. No vaccination schedule was practised and no antibiotics were added in rations. Group A served...

In this study, the effect of water and alcoholic (ethanol) extracts Caper Bush Capparis spinosa L., Cumine Cuminum cyminum L. , Black pepper Piper nigrum Sage Salvia sp. Cat thyme Teucrium polium plants on 4th instar larvae Culex quinquefasciatus have been evaluated .The results showed that extract P. had highest larvae, with 48h LC50 155. 9 ppm followed by ethanol C. 308.2 ,315.1and 791.4 resp...

Pepper is one of the most famous and widespread spices in world. This commercial plant belongs to Piperaceae family. Depending on treatment which pepper fruit exposed, we distinguish between black, white green pepper. In this research, methanolic extracts different types (Piper nigrum) pink (Schinus terebinthifolius Raddi) were prepared. Maceration ultrasonic extraction used extract bioactive c...

Penelitian bertujuan untuk mengetahui pengaruh konsentrasi, lama perendaman dalam rootone-F dan interaksi antara konsentrasi rotoone-F terhadap pertumbuhan stek lada (Piper nigrum L.) Rancangan yang digunakan adalah Acak Kelompok (RAK) dengan dua faktor tiga ulangan. Faktor pertama Rootone-F 4 taraf (K0: tanpa rootone-F; K1: 100ppm; K2: 200 ppm K3: 300 ppm). kedua 3 (P1: selama 1 jam; P2: 2 P3:...

Seed-borne fungal pathogens present significant constrain to the production and conservation of many seed crops including cowpea. Infection mature seeds by such could result in mycotoxin contamination, loss viability, decay seeds. This study aimed identify seed-borne fungi on 200 accessions cowpea under cold storage at CSIR-Plant Genetic Resources Research Institute (PGRRI), Ghana. Also, antifu...
