“…Generally, results in Tables 2 and 3 illustrate the positive responses of K fertilization on maize yield and its components which may be attributed to medium level of available K in soil (Table 1) and to the importance of K for increasing maize yield components and then stalk and grain yields, or may be due to increasing the tolerance of plants to drought under the climatic conditions of Aswan Governorate (Cox, 2001 andWiebold andScharf 2006). Similar results were obtained by Tabatabaii, et al, (2011), Ahmad et al, (2012) El-Dissoky et al, (2013 and Abd El-Rheem et al, (2015). Tables 2 and 3 show also that foliar fertilization of B at 25 and 50 mg L -1 significantly increased ear length, number of rows ear -1 , 1000-grain weight; ear weight as well as stalk and grain yields fed -1 in favor of 50 mg B L -1 , while the increases in plant height, and ear diameter were insignificant.…”

“…Yet, potassium plays important roles in plant; potassium involved in most steps of the protein synthesis, especially transport of amino acids to developing seeds (Mengle, 1980 andBlevins, 1985). These results are in accordance with those of Ahmad et al (2012) and El-Dissoky et al (2013). Boron effect: data in Tables 5 and 6 illustrate that foliar spraying of B (B 1 and B 2 ) significantly increased N, P, K and B concentrations and contents in grain.…”

Potassium (K) and boron (B) are essential nutrients for plant growth, yield and quality, for their roles as enzymes activities and for sugars and carbohydrate transport as well as the synergetic relationship between them. In addition, plants that are large consumers of K require B levels greater than 20 ppm in the tissue to accomplish this. Also, to achieve or maintain maximal maize yields, supplemental K and B fertilization is often required, particularly on soils testing low for native available soil K and B. So, two field experiments were carried out during the two successive summer growing seasons of 2015 and 2016 at Kom Ombo Agriculture Research Station, Aswan Governorate (Latitude 24° 47 ' 21.40" N, Longitude 32° 92' 47.5" E), to evaluate the response of maize crop (Zea maize L. c.v yellow single hybrid 168) to K and B fertilization. Treatments were carried out in a split plot design with three replicates; the main plots were assigned for 6 rates of K fertilizer: K 1 (control: without K fertilization), K 2 (24 kg K 2 O fed -1 ), K 3 (36 kg K 2 O fed -1 ), K 4 (48 kg K 2 O fed -1 ), K 5 (foliar applied 2% K 2 O) and K 6 (24 kg K 2 O fed -1 + foliar applied 2% K 2 O), and the split plots were devoted to three treatments of foliar applied B (B 0 : without B, B 1 : 25 mg B L -1 and B 2 : 50 mg B L -1 ). Results demonstrated the importance of potassium and boron fertilization for maize crop yield and its quality under the present conditions. Results showed that addition of K fertilizer rates as soil and/or foliar with boron increased maize grain yield, its components and quality. N, P, K and B concentrations and uptake in both stalk and grain were also significantly increased. Yet, interactions among K fertilization rates and foliar applied B significantly increased grain and stalk yields as well as grain contents of carbohydrate and oil. The highest grain and stalk yields (3700 and 5369 kg fed -1 , respectively) were recorded by the interaction of K 4 ×B 2 without significant differences between it and the yields recorded by the interactions of K 3 ×B 2 or K 6 ×B 2 . N, P, K and B concentrations or uptake in grain and stalk increased with interaction between K and B, but these increases were only significant for K and B. On the other hand, economic evaluation of the studied treatments illustrated that the treatments of K 6 (24 kg K 2 O fed -1 +foliar applied 2% K 2 O) and K 3 (36 kg K 2 O fed -1 ) with foliar applied 50 mg B L -1 were the most profitable since they achieved the optimum maize grain yield under this study conditions.

“…Potassium application to maize crop grown in saline soil decreased sodium percentage and enhanced potassium percentage in maize grain and stalk as well as distinctly boosted the maize salt tolerance by decreasing the sodium to potassium ratio. The most significant effect was observed at higher potassium fertilizer application rates [67].…”

Maize is a cross-pollinated, polymorphic plant in nature. It is commonly a moderately salt-sensitive crop. Salinity stress is the main abiotic factor that arrests the physiological characteristics and plant growth of a maize plant. It causes the osmotic effect, associated with an increase in phytotoxic ions, oxidative stress by increased reactive oxygen species (ROS) production, and ionic effect in the cytosol. These salinity effects hinder the maize plant’s physiological processes such as respiration, photosynthesis, transpiration, stomatal functioning, hormone regulation, and functioning, seed germination, and dormancy and water relation with plants and ultimately reduce the plant growth and yield. However, the physiology of maize subjected to salinity shows various responses that depend on the genetic responses and growth stages. Maize plant undergoes many physiological changes and adapts some mechanism internally to cope with salinity stress. Numerous mitigating strategies such as application of chemicals, application of plant growth-promoting rhizobacteria (PGPR), application of hormones, and use of genetic and molecular techniques are used to handle salinity. This chapter will cover the effect of salinity on maize growth, its physiology, and physiological adaptations of maize plants with management strategies.

“…Na + concentration increased in saline soils, showing a higher value of Na + /K + ratio. Conversely, K application exogenously decreased this ratio and alleviated the nasty effects of Na in maize [210,211]. Recently, Hussain et al [211] claimed that applying K sulfate and diammonium phosphate (DAP) as a mixture in saline soil increased the growth and productivity of maize.…”

Maize, along with rice and wheat, is a popular staple food crop worldwide, and the most widely produced cereal crop. It is a versatile crop that may be utilized as a source of raw materials for human and animal fodders. Low agricultural yield and rapid population expansion significantly threaten future food security. Maize production is hampered by biotic and abiotic causes, with abiotic factors being the most critical limitation to agricultural output worldwide. Soil salinity is a key abiotic factor that reduces agricultural production by imposing negative impacts at several life cycle phases, including germination, seedling, vegetative, and reproductive development. Maize plants experience many physiological changes due to osmotic stress, toxicity of particular ions, and nutritional imbalance induced by salt stress. The degree and duration of stress, crop growth phases, genetic characteristics, and soil conditions influence yield reduction. Maize plants can tolerate salt stress involving a complex mechanism by changing their physiological, biochemical, and metabolic activities like stomatal functioning, photosynthesis, respiration, transpiration, hormone regulation, enzymes, metabolite generation, etc. After studying the salt tolerance mechanisms of maize plants under stress, integrated management techniques should be developed for maize agriculture in saline settings. Therefore, the study of plant responses to salt stress, stress tolerance mechanisms, and management strategies is one of the most imperative research fields in plant biology, and the study will focus on the effects of salt stress in different growth stages, plant tolerance mechanisms, and agronomic management practices for successful maize production all over the world.
