“…In case of N:K correlation, there can be stated that the better plants are nourished with K in relation to N the better is their resistance and the higher is the predictive value. The above relationship was also showed by the results of other studies concerning quality wheat (Gaj 2010(Gaj , 2013. The mechanism of interaction between N and K as well as N and P has been well documented in subject literature (Marschner, et al, 1996;Greenwood and Stone 1998;Broadley, et al, 2004).…”

The aim of the study carried out under field conditions was to evaluate the effect of differentiated phosphorus and potassium fertilization level on nutritional status of winter wheat at stem elongation (BBCH 31) and flowering (BBCH 65) development stages as well as on macronutrient contents in yield obtained (grain and straw). The research was conducted in 2007-2010, within an individual agricultural holding, on lessive soil with medium and high richness in potassium and phosphorus, respectively. The contents of nitrogen, phosphorus, potassium, magnesium and calcium in wheat changed depending on the organ assessed and plant development stage. At BBCH 31, regardless fertilization level, the plants observed were malnourished with potassium, phosphorus and calcium and at the control site -also with nitrogen. Furthermore, there were found significant correlation relationships among the contents of nutrient pairs: nitrogen-potassium, nitrogen-phosphorus, nitrogen-magnesium and nitrogen-calcium. The content of nitrogen in wheat grain and straw differed mainly due to weather conditions during the study. Irrespective of the years of observation, differentiated rates of P and K applied had no significant effect on N accumulation in wheat at full ripening stage. In contrast to nitrogen, the level of P and K fertilization significantly differentiated the contents of phosphorus, potassium and magnesium in wheat grain and straw. In case of calcium, the effect of fertilization factor was indicated only as regards the content of this nutrient in grain. początku strzelania w źdźbło (BBCH31) i kwitnienia (BBCH65) oraz zawartość makroskładników w ziarnie i w słomie pszenicy ozimej. Doświadczenie przeprowadzono w latach 2007-2010 w indywidualnym gospodarstwie rolnym, na glebie płowej o średniej zasobności w potas i wysokiej w fosfor. Zawartości azotu, fosforu, potasu, magnezu i wapnia w pszenicy zmieniały się w zależności od organu rośliny oraz fazy rozwojowej. Niezależnie od poziomu nawożenia mineralnego w fazie BBCH 31 rośliny były niedożywione potasem, fosforem, wapniem, a w stanowisku kontrolnym dodatkowo azotem. Ponadto stwierdzono istotne zależności korelacyjne pomiędzy zawartościami analizowanych par składników: azot -potas, azot -fosfor, azot -magnez oraz azot -wapń. Zawartość azotu w ziarnie i w słomie pszenicy ozimej była zróżnicowana głównie warunkami pogodowymi w latach badań. Zróżnicowane dawki P i K niezależnie od roku badań nie miały również istotnego wpływu na akumulację N w fazie dojrzałości pełnej. W odróżnieniu od azotu, poziom nawożenia mineralnego P i K istotnie różnicował zawartość fosforu, potasu i magnezu w ziarnie i słomie pszenicy. W przypadku zawartości wapnia działanie czynnika nawozowego zaznaczyło się tylko w odniesieniu do zawartości składnika w ziarnie.Słowa kluczowe: zawartość makroskładników, stan odżywienia, dawki fosforu i potasu, pszenica ozima Streszczenie szczegółowe Jednym z podstawowych czynników ograniczających potencjał plonowania pszenicy ozimej jest stan odżywienia roślin w faz...

“…In addition, the result confirms that the dose of phosphorous fertilization has a significant effect on the chemical compositions of wheat grain. It is generally believed, however, that phosphorus slightly affects grain proteins in winter wheat (Batten, Fettell, Mead, & Khan, ; Benbella & Paulsen, ; Gaj, Górski, & Przybyl, ). Berecz () pointed out that the influence of phosphorus fertilization on wheat quality characters dependent largely on the nitrogen and phosphorus rates (Gaj et al., ).…”

The objective of this research was to study the effects of phosphorous and foliar iron fertilizations rates on the of protein, fiber, and water contents in wheat grains. Treatments of fertilizers included a combination of three foliar iron rates (0, 1.2, and 2 L/ha, Fusion) and four phosphorus rates (0, 75, 150, and 225 kg/ha, P2O5) at three replications. The quality parameters of harvested seeds were measured by the NIR technique. Protein content increased but and fiber and water contents decreased significantly with an increase in the iron and phosphorus fertility rates. As the rates of foliar iron increased from 0 to 2 L/ha the mean values of protein content increased significantly from 13.47% to 15.48%. With increasing the rates of phosphorus from 0 to150 kg/ha, the mean values of protein content increased significantly from 13.56% to 15.53%, however, further increase in phosphorus, causing a decreased trend in the amount of protein. Fiber and water contents of wheat decreased significantly from 13.76% to 11.86% and from 7.36% to 7.28%, respectively, as the phosphorous rate increased from 0 to 225 kg/ha. Those changes were from 13.40% to 12.03% and from 7.57% to 7.21%, respectively, for increasing foliar iron from 0, 1.2, and 2 L/ha. Mathematical relationships composed of phosphorus and iron fertilizers were developed for accurately describing the wheat protein, fiber, and water contents under different fertilization rates.

“…Wheat grain yield significantly depended on plant nutrition at the beginning of stem elongation stage [29]. Nitrogen is the key element in plant nutrition limiting plant growth and crop yields in many agro ecosystems, rain fed as well as irrigated systems [30], it is part of the protoplasmic structural proteins, cell nuclei, nucleic acids, pigments, vitamins and enzymes [31], is the most limiting nutrient for wheat production that affects the rapid plant growth and improves grain yield.…”
