“…In a work on two cultivars of broad bean, two sources of K + , i.e., KNO 3 and CH 3 COOK, were used in a nutrient solution to combat salinity. However, neither was growth improved nor the K + concentration increased in the plant tissue (Bulut et al, 2011).…”

About 7% of the total land around the globe is salt-affected causing a great loss to agriculture. Salt stress refers to the excessive amount of soluble salts in the root zone which induce osmotic stress and ion toxicity in the growing plant. Among toxic ions, sodium (Na + ) has the most adverse effects on plant growth by its detrimental influence on plant metabolism in inhibiting enzyme activities. An optimal potassium (K + ) : Na + ratio is vital to activate enzymatic reactions in the cytoplasm necessary for maintenance of plant growth and yield development. Although most soils have adequate amounts of K + , in many soils available K + has become insufficient because of large amounts of K + removal by high-yielding crops. This problem is exacerbated under sodic or saline-sodic soil conditions as a consequence of K + -Na + antagonism. Here K + uptake by plants is severely affected by the presence of Na + in the nutrient medium. Due to its similar physicochemical properties, Na + competes with K + in plant uptake specifically through high-affinity potassium transporters (HKTs) and nonselective cation channels (NSCCs). Membrane depolarization caused by Na + makes it difficult for K + to be taken up by K + inward-rectifying channels (KIRs) and increases K + leakage from the cell by activating potassium outward-rectifying channels (KORs). Minimizing Na + uptake and preventing K + losses from the cell may help to maintain a K + : Na + ratio optimum for plant metabolism in the cytoplasm under salt-stress conditions. It would seem a reasonable assumption therefore that an increase in the concentration of K + in salt-affected soils may support enhanced K + uptake and reduce Na + influx via HKTs and NCCSs. Although very useful information is available regarding K + -Na + homeostasis indicating their antagonistic effect in plants, current knowledge in applied research is still inadequate to recommend application of potassium fertilizers to alleviate Na + stress in plants under sodic and saline-sodic conditions. Nevertheless some encouraging results regarding alleviation of Na + stress by potassium fertilization provide the motivation for conducting further studies to improve our understanding and perspectives for potassium fertilization in sodic and saline-sodic environments. : Exogenously supplied compatible solutes rapidly ameliorate NaCl-induced potassium efflux from barley roots. : Loss of the AKT2/3 potassium channel affects sugar loading into the phloem of Arabidopsis.

Faba beans are highly nutritious because of their high protein content: they are a good source of mineral nutrients, vitamins, and numerous bioactive compounds. Equally important is the contribution of faba bean in maintaining the sustainability of agricultural systems, as it is highly efficient in the symbiotic fixation of atmospheric nitrogen. This article provides an overview of factors influencing faba bean yield and quality, and addresses the main biotic and abiotic constraints. It also reviews the factors relating to the availability of genetic material and the agronomic features of faba bean production that contribute to high yield and the improvement of European cropping systems. Emphasis is to the importance of using new high-yielding cultivars that are characterized by a high protein content, low antinutritional compound content, and resistance to biotic and abiotic stresses. New cultivars should combine several of these characteristics if an increased and more stable production of faba bean in specific agroecological zones is to be achieved. Considering that climate change is also gradually affecting many European regions, it is imperative to breed elite cultivars that feature a higher abiotic–biotic stress resistance and nutritional value than currently used cultivars. Improved agronomical practices for faba bean crops, such as crop establishment and plant density, fertilization and irrigation regime, weed, pest and disease management, harvesting time, and harvesting practices are also addressed, since they play a crucial role in both the production and quality of faba bean.

“…Experimental studies related to nutrient-salt interactions, and plant growth and quality were completed for several plants, including: horticultural crops (Prazeres et al 2013;Saykhul et al 2013), leguminous crops (Correia et al 2010;Bulut et al 2011) and grasses (Morshedi and Farahbakhish 2012). It was shown that yield response to salinity tolerance is not always a constant as the model of Maas and Hoffman (1977) suggests, but fertilization increases tolerance to salinity (salinity threshold value); however, at high salinity levels, the osmotic effect is more pronounced and enhanced fertilization may provoke a negative effect on crop yield .…”

The Influence of Nutrients on Turfgrass Response to Treated Wastewater Application, Under Several Saline Conditions and Irrigation Regimes

The vast development of golf courses implemented in arid and semiarid regions, and the intense aquifer pumping rate of the water needed to irrigate these grass lands, provokes saline problems, mainly in the coastal areas, due to sea water intrusion. The reuse of treated wastewater to irrigate golf courses is considered as an alternative to the use of potable and ground water. The objective of this work was to study the response of Bermuda grass (Cynodon dactylon, L. Pers) to several irrigation rates I with reused treated municipal wastewater in two locations in southern Portugal. Three different irrigation regimes based on different values of electrical conductivity (EC w ), namely EC w =0.3 dS m −1 (potable water; control treatment), EC w =1.6 dS m ). We conclude that wastewater can be used to irrigate turfgrass as an alternative to potable water due to the presence of significant quantities of some essential nutrients, like K. However, the EC of wastewater can be a limiting factor.
