The purpose of this paper was to determine the factors affecting farmers’ satisfaction from Water Users Associations (WUAs) in the Harran Plain-Turkey. The data used in this study come from a sample of 378 farmers among 23,204 in the Şanlıurfa-Harran Plain. They were chosen via simple random sampling method and interviewed face to face. Sampling was conducted in 52% of the settlements. To analyze the collected survey data, SPSS 15 was used together with Kruskal Wallis, Mann-Whitney, Pearson Chisquare and the correlation tests. The results indicated the existence of relationship between satisfaction and education levels, knowledge level about WUA, and status of ownership, land area, age, farming experiences, income, and service quality given by WUAs. These factors significantly explained satisfaction of farmers. The average of variables’ highest satisfaction was calculated as 47.4%. The highest satisfaction was 68.5% and belonged to the status of ownership; the lowest one was 28.3% in the case of farming experiences. The managers of WUAs should be concentrating on these factors in order to increase satisfaction and provide training and information for farmers. © 2015, Tarbiat Modares University.

Eichhornia crassipes (Mart.) Solms (Pontederiaceae) is reported for the first time for the flora of Turkey. This invasive alien plant was observed in the Asi River (also called the Orontes River), which runs from Lebanon, through Syria to Turkey. The observation was made in the river near the border with Syria. This site is the in the district of Altinözü in the province of Hatay in the East Mediterranean region. Turkey is divided into grids for floral purposes by the book 'Flora of Turkey' and the plants described were collected in grid sector C6. The authors concluded that E. crassipes (water hyacinth) can establish and spread in Turkey. © 2014 OEPP/EPPO.

Turkey is one of the richest areas in the middle latitudes in terms of plant diversity. It has approximately 12 000 plant species and a great number of new species are being added each year. However, invasive alien species have not yet been fully considered in Turkey and only two plant species are in Turkey's quarantine list (Arceuthobium spp. and Eichhornia crassipes). EPPO is an intergovernmental organization responsible for cooperation in plant protection in the European and Mediterranean region and maintains the A1 and A2 Lists of pests recommended for regulation (A1 species are absent from the EPPO region, A2 species are present but of limited distribution), the List of Invasive Alien Plants, the Observation List of invasive alien plants and the Alert List. Eichhornia crassipes, Heracleum persicum, Heracleum sosnowskyi, Ludwigia peploides, Polygonum perfoliatum and Solanum elaeagnifolium are among the species which were recorded in Turkey and are included in the EPPO A2 List. Species recorded in the EPPO List of invasive alien plants which are present in Turkey are: Acroptilon repens, Ailanthus altissima, Ambrosia artemisiifolia (= A. elatior), Carpobrotus edulis, Cortaderia selloana, Cyperus esculentus, Paspalum distichum (= P. paspalodes), Oxalis pes-caprae and Sicyos angulatus. Azolla filiculoides and Rhododendron ponticum are listed in the EPPO Observation List of Invasive alien plants and Miscanthus sinensis, listed in the EPPO Alert List, are also recorded in the Turkish flora. © 2015 OEPP/EPPO.

This study aimed to determine the optimum seed amount and inter-row spacing in aniseed (Pimpinella anisum L.) cultivation. The study was conducted at the research field of Faculty of Agriculture at Harran University for two seasons (2001 and 2002). The treatments consisted of two row spacing (15 and 30 cm) and four seed amounts (10, 20, 30 and 40 kg ha-1). The following results were obtained from both years: seed yield varied between 958.0 and 1470.0 kg ha-1, essential oil yield varied between 27.5 and 46.4 l ha-1, 1000-seed weight varied between 3.2 and 3.9 g, seed number per umbel varied between 124.8 and 203.6, number of branch per plant varied between 4.3 and 8.2, and number of umbels per plant varied between 5.1 and 12.2. The highest seed yield was obtained from interaction of 15 cm row spacing and 20 kg ha-1 seed amount applications. Overall applications were found to be ineffective on (E)-anethole rates. © 2014 Har Krishan Bhalla & Sons.

It is reported that sulphur deficiency in soils and plants has become widespread. Despite the numerous studies reporting on the effects of sulphur application on growth, yield, yield components and quality parameters in various plant species, very little research has been done in cotton in this respect. Therefore, field experiments were conducted in 2005, 2006 and 2007 to investigate the effects of different sulphur application rates (0, 30, 60, 90 and 120 kg ha-1) on the yield and yield parameters of cotton (Gossypium hirsutum L.) in the Harran plain of Southeastern Turkey. The results demonstrated that sulphur application increased the yield by 3.3-17.1% depending on the rates. The effects of sulphur application on the yield also differed with years. It was established that the increase in yield was due to positive effects of sulphur application on yield parameters. The results indicate that sulphur application could alleviate yield reductions resulting from sulphur deficiency.
