“…These findings were expected since K is commonly required by plants in greater amounts (Niu et al, 2013). In addition, this nutrient is associated with osmoregulation processes, cell extension, opening and closing of stomata, activation of enzymes and synthesis of proteins (Marschner, 2012;Pettigrew, 2008).…”

The purpose of this work was to assess biometric parameters of cedar seedlings (Acrocarpus fraxinifolius) associated with visual symptomatology of macronutrients deficiency, growth rate, and content and accumulation of nutrients in aerial parts of seedlings grown in nutritive solution. The trial was established in completely randomized design with seven treatments, four replications, and one plant per pot. Treatments consisted of complete nutrient solution, Hoagland and Arnon, and deprivation of the following selected single nutrients: N, P, K, Ca, Mg and S. Micronutrients were provided to all treatments. The following biometric parameters were assessed 90 days after the transplant: shoot height, root collar diameter, root and shoot dry weight. The Dickson index and the ratio given by roots dry weight and shoot dry weight were obtained, as well as the content and accumulation of nutrients in aerial parts of seedlings. The Sisvar statistical analysis system was run for analysis of variance, and averages were compared by means of Scott-Knott test at 5% significance. Treatments consisting of omissions of macronutrients were found to be limiting factors of plants growth and obtaining of seedlings shoot dry weight in the following order: N > P > K > Ca > Mg > S. Deficiencies of these macronutrients caused visible morphological abnormalities, where common symptoms of deficiency of N, P, K and Ca appeared before symptoms of deficiency of Mg and S. The content of nutrients found in aerial parts of seedlings of A. fraxinifolius grown in nutritive solution was greater for treatments consisting of deprivation of N, P and K. The content of nutrients found for treatments consisting of deprivation of Mg and S was not significantly different from that found for the complete nutrients solution.

“…The supply and output of N and P are nearly in balance, whereas the supply of K is much lower (only 35% of output) (Smil, 1999). With the increase of nitrogen and phosphorus fertilizer inputs and intensive cropping, the lack of potassium has become the most factor limiting wheat yields (He et al, 2012;Niu et al, 2013;Rafique et al, 2012). K-fertilizers should be added to soil to compensate for the lack of potassium.…”

We investigated the differences of K acquisition and utilization, morphological and physiological characteristics of roots and grain yield between Elymus dahuricus H + -PPase (EdVP1) transgenic wheat and wild type wheat under low K stress. The results showed that, the grain yield and K economic utilization index (KUI-E) in wild type wheat were only 61.14% and 50.20% of those in EdVP1 transgenic wheat. EdVP1 increased the free IAA accumulations in roots, which may play a key role in the development of root system. The total root length, total root surface area, root tips and total root volume in transgenic wheat were 2.26, 2.23, 2.34 and 2.00 times as high as those in wild type wheat, respectively. Excretion H + and cation exchange capacity (CEC) of roots, which were enhanced in transgenic wheat, were positively correlated with K content.The exudate of organic acid intransgenic wheat was 2.22 times as high as that in wild type wheat, leading to the strong K activation of transgenic wheat. Therefore, we assume that well-developed rootsystem containing prosperous root morphology, high excretion H + and CEC of roots and strong excretion ability of organic acids improved K acquisition and utilization efficiency in EdVP1 transgenic wheat.

“…These authors evidenced the importance of crop rotation on yields and soil natural fertility on fertilization management practices, mainly for nitrogen. Likewise, Niu et al (2013) affirmed that N and P absorptions could increase with K fertilization. In addition, differences in fertilization timing for both nitrogen and potassium might have played a role in the individual responses of the characteristics assessed.…”

“…Despite not taking part in any chemical structure of organic compounds, potassium enhances the resistance to lodging in wheat plants. It has been reported that nitrogen and phosphorus fertilization can be more effective when potassium fertilization increases (Niu et al, 2013). For Chuan et al (2013), N is the most limiting nutrient for wheat yield, followed by P and K. Besides that, potassium increases grain yield if not in excess thereof (Zhan et al, 2016).…”

This study aimed at assessing the effects of nitrogen-potassium interaction on dry matter and grain yield of irrigated wheat (Triticum aestivum L.) grown in the Brazilian Cerrado. The experiment was conducted for two consecutive cropping seasons (2014 and 2015), between March and August. The experiment was arranged in a randomized block design. Treatments consisted of five nitrogen and five potassium doses in a factorial scheme (5×5). The analyzed variables consisted of the shoot and spike dry weights, and grain yield. In both years (2014 and 2015), isolated effects of nitrogen and potassium doses were observed on the assessed traits. In 2014, the highest results were achieved by the respective nitrogen and potassium doses: 145.02 and 148.32 kg ha -1 for shoot dry weight, 133.79 and 139.85 kg ha -1 for spikes, and 119.14 and 138.83 kg ha -1 for grain yield. Yet in 2015, no significant results were identified, while nitrogen doses showed a linear effect on shoot and spike dry weights, potassium rates revealed such effect on grain yield. Although nitrogen showed a higher response in terms of dry weight for shoot and spikes, potassium induced the largest increases in productivity. Thus, for greater efficiency of fertilization, a careful analysis of the level of soil fertility, the expected productivity and the technological level employed is necessary. It should be emphasized that the management of fertilization has specificities every year, requiring constant adaptation.Keywords: BRS 254 wheat; Cerrado wheat production; nitrogen-potassium ratio; nitrogen and potassium fertilizations; Triticum aestivum.
