Samir K. Ali | Ghorbat S. Ali | Berivan Abdulrahman Abdullah
The widespread use of antibiotics often causes increase in the bacterial drugs resistance and causes many side effects in humans. Medical plants have antimicrobial effects against most pathogenic bacteria and can serve as harmless replacement to antibiotics. The aim of this study was to assess the antibacterial effect of five medicinal plant prevailed in Kurdistan region namely; Cinnamon (Cinnamomum cassia (L.) D.Don), Nigella (Nigella sativa L.), Allium (Allium hirtifolium Boiss.), Carrot (Daucus carota L.), and Fennel (Foeniculum vulgare Mill.) against pathogenic Gram positive bacteria (Staphylococcus aureus), and pathogenic Gram negative bacteria (Salmonella typhi and Escherichia coli). The evaluation of antibacterial activity for these plant extracts was carried out using agar-well diffusion method. Results showed that minimum inhibitory concentration (MIC) of A. hirtifolium against tested bacterial isolates were (25 mg/mL), the lowest MIC values for S. aureus were (25 mg/mL) observed with C. cassia, N. sativa and F. vulgare ethanolic extracts and the lowest MIC of D. carota against bacterial isolates were (50 mg/mL), Also, it was observed that S. aureus was more sensitive than S. typhi and E. coli to plant extracts. The ethanol plant extracts had potential antibacterial activities. However, further studies are required to identify the active compounds which could be used for the preparation of new antimicrobial agents and control the bacterial infectious diseases.

In this study, antioxidant, oxidant and oxidative stress index of Thymbra spicata L. collected from Duhok (Iraq) region were determined. The aerial parts of the plant were extracted with ethanol. Rel Assay Diagnostics kits were used for detect TAS, TOS and OSI values. As a result of the studies, it was determined that TAS value of plant extract was determined 8.399±0.102, TOS value was 6.530±0.115 and OSI value was 0.078±0.001. As a result, it was determined that T. spicata has high antioxidant potential and in this context, can be used as a natural resource.

The study was conducted in Mahanawiyah district in AL-Qadisiya Province, Iraq to identify the training needs of rice farmers. 125 farmers were selected as a random sample. A list of 8 major areas of training needs in relation to rice cultivation practices was prepared whiten 50 sub-area. Scores were measured on four-point scale. The primary data were collected using a pre-tested structured interview schedule by conducting personal interview. Findings revealed that majority of the farmers had medium level of training needs. Weed management, disease and pests control, seed and seedling were the top most training needs of the farmers and the least training need was Land preparation. The variables educational attainment, area cultivated with rice, and annual revenue from rice cultivation had positive and significant association with the training needs.

An analysis of heterosis and combining ability of traits related with per plant production was carried out using a diallele crossing between different tomate cultivars, Lycopersicon esculentum Mill (six parent and 15 F1 hybrids from as possible crossing in one direction), according to the methodology proposed by Griffing (1956), selecting experimental method 2, and model 1. In the genetic variation of all traits related to per plant production, except in first class fruit trait, the general combining ability (gen non addite action) effects participate jointly and in highly significant manner. Hybrids Motelle x Angela I 5100, Motelle x Zambao y Licapal21 x Zambao, exhibited high s c a effects for the trait per plant production. Former effects related to high heterobeltyosis make these hybrids promising for later marketing. | Se realizó el análisis de la heterosis y de la habilidad combinatoria entre 21 cultivares de tomate, para el carácter producción por planta y sus componentes a partir de un cruzamiento dialélico (6 progenitores, 15 híbridos F1, sin incluir los recíprocos): utilizando el método experimental 2, modelo I propuesto por Griffing (1956). Se encontraron diferencias altamente significativas para los efectos de hcg y de hce para todos los caracteres a excepción del carácter producción de frutos de primera (frutos de más de 180 g). Los híbridos Motelle x Ángela I 5100, Motelle x Zambao y Licapal 21 x Zambao presentaron altos efectos de h c e para el carácter producción por planta. Los anteriores efectos asociados con altas heterobeltiosis hacen que estos híbridos sean promisorios para una posterior comercialización.
