<em>Hypericum pruinatum</em> is a medicinal herb containing several bioactive compounds with important pharmacological activity. In this study, we investigated the effects of salt (0.03 - control, 1, 2.5, 4 and 8 dS m<sup>–1</sup> MgSO<sub>4</sub>, CaCl<sub>2</sub> NaCl salts) drought stress (80, 100 120% required water) on content phenolic compounds, namely chlorogenic acid, rutin, hyperoside, isoquercetine, quercitrine quercetine in...
Abstract This study was conducted to assess the influence of different salinity and irrigation water treatments on growth development sweet basil (Ocimum basilicum L.). Five levels (0.4, 1.00, 2.50, 4.00 8.00 dSm -1 ) three regimes (80, 100, 120% full irrigation) were applied in a factorial design with replications. Dry root weight, aerial part dry weight part/root ratio determined evaluated as experimental parameters at end growing period. Results revealed significant decreases yields...
Abstract Lack of water resources and high salinity levels are among the most important growth-restricting factors for plants species world. This research investigates effect irrigation on reflectance Saint John’s wort leaves (Hypericum perforatum L.) under stress conditions (water salt stress) by multiple linear regression (MLR), artificial neural network (ANN) adaptive neuro-fuzzy inference system (ANFIS). Empirical heuristics modeling methods were employed in this study to relate leaf...
This tutorial is based on modification of the professor nomination lecture presented two years ago in front Scientific Council Czech Technical University Prague [16].It devoted to techniques for models developing suitable processes forecasting complex systems.Because high sensitivity initial conditions and, consequently, due our limited possibilities forecast long-term horizon, attention focused leading practical applications short term prediction models.The aim this paper bring possible...
Selected engineering properties (physical and mechanical) of dry bean under non-irrigation drip-irrigation were determined compared. These are necessary for the design equipments harvesting, processing, transporting, estimating loads in storage structures crops flow problems silos such as arching, ratholing, irregular segregation. Some characteristics as: average length, width, thickness, geometric mean diameter, sphericity, surface area, volume, thousand grain mass (M1000), bulk true...
Bu çalışma Tarım Reformu Genel Müdürlüğü (TRGM) tarafından projesi yürütülen Samsun ili, Bafra İlçesine bağlı 20 mahallede, Amasya ili Merkez ilçeye 10, Göynücek İlçesinde 2, Gümüşhacıköy ilçesinde 10 köyde, Sinop Boyabat 14, Durağan ilçe merkezi ve 3 köyde olmak üzere toplam 60 proje sahasında yapılan toplulaştırma projelerinde başarının değişik kriterlere göre değerlendirilmesi bunda yeni bir bakış açısı ortaya konulması amacıyla yapılmıştır. Başta parsel sayısı üzerinden oranı (TO) 17...
Analiz sonuçları kullanılarak haritalar çizilmiş ve arazinin N, P, K dağılımları çıkarılarak hassas tarım için veri elde edilmiştir.Araştırma sonuçlarına göre ortalama gübre ihtiyacı göz önüne alındığında; 763 kg azotun ihtiyaç olmayan bölgelere fazladan uygulanacağı, 313 ise eksik olarak uygulanacağı belirlenmiştir.Ayrıca Fosfor açısından 355.5kg fazlası uygulama yapılırken 370.2 olan yere atılamayacağı hesaplanmıştır
Dry bean (phaseolus vulgaris L.) field experiment was carried out under the subhumid climatic conditions of Bafra, Turkey, to evaluate possibilities using hyperspectral reflectance data for estimating yield and water consumption. Three irrigation management treatments that depend on monitoring soil content one rain-fed treatment were subjected dry beans arranged in a randomized complete block design with three replications. In addition measurements, observations made throughout beans?...
Sodyum derişiminin yüksek olduğu sulama sularıyla toprağın sulanması genellikle sodyum içeriğinin artmasına neden olur. Sulama suyunun sahip tuz ve Absorbsiyon Oranı (SAR) değerleri fiziksel yapısında önemli değişiklikler meydana getirmektedir. Yapılan çalışmalarda killi topraklarda sınırlandırıcı değişebilir Na miktarının 1 - 1.5 meq 100-1 g toprak belirtilmiştir ki bu değer 4-8 Değişebilir Yüzdesi (ESP) değerine karşılık gelmektedir. çalışmada EC sabit 0, 15, 30, 40 SAR değerlerine...
ÖZET:
Bafra ovasi kosullarinda karik sulamada uygun boylarinin belirlenmesi icin akis denemeleri yapilmis ve parametreleri degerlendirilmistir. Kariklarda 1.5, 2.0 2.5 L/s debiler kullanilarak infiltrasyon durumu ortaya cikarilmistir. Net surelerinin debide sirasiyla 205 dakika, 159 dakika 117 oldugu belirlenmistir. Karik belirlenmesinde net suresinin ¼’u kadar surede suyun sonuna ulasmasi gerektiginden debilerde cikarilan ilerleme egrileri 86.6, 92.5 97.3 m olarak en boylari belirlenmistir
In this study, some of the empirical methods such as USDA-SCS and volume balance equations were used for determining furrow length. The main purpose was proving application possibility. According to results, Volume Balance Equations can be length at Bafra Plain, Turkey. field experiment results are very close each other. Experimental different from equation but there is a relationship between both. There coefficient result (0.41) multiply by UDSA-SCS 73 m which experimental 71 m.
Sodyumlu toprakların oluşumunda en önemli etkenlerden biri de sulama suları içindeki sodyum düzeyidir. Her yapıldığında tarım alanlarındaki birikmesi, bitki aksamlarındaki değerlerini değiştirebileceği gibi toprağın değişebilir yüzdesi (ESP), toprak tuzluluğu (ECe) ve kullanılabilir suyu miktarı (AWC) özelliklerini etkilemektedir. Bu çalışmada kırmızı lahanaya tuzluluk değerleri aynı fakat adsorbsiyon farklı (SAR0, SAR5, SAR15, SAR30 SAR40) 5 uygulanmıştır. Parametre olarak katmanlar için...
This study aimed to assess the kinetics and changes in bioactive compounds, color, technological properties of Mint Vanilla Titicaca quinoa varieties stored during 360 days at 4, 10, 25°C. It was observed that an increase storage time temperature decreased total phenolics (except 25°C for Vanilla), flavonoids, DPPH, FRAP contents both varieties. After storage, it determined conditions had a significant (p < .05) effect on properties. Color change affected by temperature, with most prominent...
