A factorial completely randomized block design experiment with three replications was carried out in greenhouse to evaluate cereal genotypic variation in phosphorus (P) acquisition and utilization efficiency in a calcareous soil with low available P (4.6 mg P kg-1 soil) and high total P (1260 mg P kg-1 soil). Treatments consisted of eight bread wheat (Triticum aestivum L.), three durum wheat (T...

Pasture productivity in the Mediterranean region depends mainly on soil water deficit. Subterranean clover originates from and is adapted to areas with hot dry summers. The response of Subclover drought was studied greenhouse subjected three soils - levels: 100% (control), 50 25% field capacity (FC). After 70 days deficit treatment, our results showed that increasing levels constraint resulted ...

The effects of different concentrations (0, 25, 50, 75 and 100%) of aqueous leachate of Achillea biebersteinii on germination characteristics, seedling growth, photosynthetic pigments and protein contents of pepper (Capsicum annuum L.) were investigated through conducting laboratory and greenhouse experiments. Leachate of A. biebersteinii affected negatively germination percentage, germination ...

Effect of cobalt (Co) stress on morphological parameters and pigments of Arachis hypogaea L. were studied. Growth parameters such as, root and shoot length, number of nodules, total leaf area and root and shoot dry weights; photosynthetic pigments viz., chlorophyll ‘a’, chlorophyll ‘b’, total chlorophyll and carotenoid contents were analysed. Growth parameters and pigments have beneficial value...

Climate change is increasingly impacting the water deficit over the world. Because of drought and the high pressure of the rising human population, water is becoming a scarce and expensive commodity, especially in developing countries. The identification of crops presenting a higher acclimation to drought stress is thus an important objective in agriculture. The present investigation aimed to a...

A rhizobacterium isolated from groundnut rhizosphere and identified as Alcaligenes faecalis BCCM 2374 produced siderophore during 24 h submerged growth in modified succinic acid medium (SM) prepared in tap water without deferration. For the optimized production of siderophore in the presence of starch and sucrose, the optimum parameters found were as follows: slight acidic pH (5.5), 35C tempera...

In arid and semi-arid areas of the world, excessive mineral aerosol carried by air parcels is a common climatic incident with well-known environmental side effects. In this study, the role of sand-dust accumulation was investigated on various aspects of photosynthetic yield of Plantago lanceolata including chlorophyll (Chl) a, b, effective quantum yield of PSII photosystem (ФPSII), maximal quan...

The study aimed to evaluate the effect of three different manganese (Mn) concentrations on plant growth, leaf chlorophyll, carotenoid content, photosynthetic activity, and root morphological development in eggplant (Solanum melongena L. ‘Adana cv. Dolmalık’ ‘Köksal F1’). Plants were grown continuously aerated nutrient solution by using a deep-water culture (DWC) technique fully automated climat...
