“…These values are similar to those reached in our study under the highest P rate (the IPAR and RUE were on averaged 833 MJ m -2 and 3.2 g MJ -1 , respectively). As in previous studies on wheat and other cereals, wheat's grain yield responses to P supply were related to the total AGB and not to HI (wheat: Manske et al, 2001;Aulakh et al, 2003;Sandaña and Pinochet, 2011). More interestingly, the present study showed that HI was also conservative in pea.…”

“…P available considers the P supplied from the soil plus P from fertilizers. PUE (g yield/g P available) = PUTE (g yield/g P uptake) x PUPE (g P uptake/g P available) (1) PUTE differences among wheat genotypes have been previously reported (Manske et al, 2001). Calderini et al (1995) found that PUTE was higher in modern wheat cultivars when compared to older cultivars, owing to the higher harvest indexes of modern wheat cultivars.…”

“…Soil phosphorus (P) deficiency is a major constraint to increased crop yields in many areas of the world (Vance et al, 2003). Relative to nitrogen and potassium, the recovery of P fertilizers by crop plants is usually very low due to soils' high capacity to fix P to soil constituents of little bioavailability (Manske et al, 2001;Lynch, 2007;Balemi and Negisho, 2012). Therefore, it is not surprising that since the green revolution, high amounts of P fertilizers have been applied to soils in order to meet the P demand of agricultural systems (Tilman et al, 2001).…”

“…Temperate cereals, especially wheat, have been much more investigated in terms of their PUE than temperate grain legumes, like pea (e.g. Batten, 1992;Gahoonia et al, 1999;Manske et al, 2001). In Southern Chile (40° S, 70° W) wheat is the most sown grain crop and pea could also be considered as an alternative crop for plant protein production (Sandaña et al, 2009).…”

The aim of the present study was to evaluate the response of grain yield, phosphorus (P) use efficiency (PUE, g yield g -1 P available) and related root traits of wheat and pea to different P availabilities in a high yielding environment (e.g.: yield higher than 10 Mg ha -1 for wheat). Two experiments were conducted in southern Chile. Treatments consisted of the combination of (i) two crops (spring-bred wheat and pea) and (ii) three rates of P fertilization (0 (P0), 100 (P1) and 250 (P2) kg P ha -1 ). Grain yield of wheat was more sensitive to P deficiency than pea. Wheat showed consistently higher (P < 0.01) PUE than pea, averaging 195 and 125 g yield g -1 P available, respectively. This was principally ascribed to the highest (P < 0.01) P utilization efficiency of wheat (430 vs. 249 g yield g -1 P uptake for wheat and pea, respectively). On the contrary, the P uptake efficiency was slightly different for these crops (0.44 and 0.49 g P g -1 P available, respectively). However, these crops presented different strategies for P acquisition. Wheat had a higher (P < 0.01) soil exploratory capacity than pea, while pea showed a higher (P < 0.01) P uptake per unit of root length than wheat. Wheat showed higher PUE than pea; however, crop differences are ascribed to differences in phosphorus utilization rather than to phosphorus uptake efficiency. This information could contribute to optimized soil P use and improved crop fertilization management.

“…Grain P is a valuable source of this nutrient for humans and animals. The additional benefit of high P contents in grain is a possibility of obtaining higher grain yields with better germination capability, which is particularly important in reproduction of sowing material (Bolland, and Baker 1988;Manske, et al 2001;De-Marco, 1990). A decrease of P contents results in reduction of grain anti-nutritional factors such as phytic acid Batten (1986).…”

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...
