“…For optimum crop yield, plants require adequate P from very early growth stages Grant et al, 2001). The success or failure of the early growth stage of developing seedlings is directly related to successful remobilization of stored grain P reserves that were accumulated throughout the ripening period (Guardiola & Sutcliffe, 1971;Le Deunff, 1975;Lawrence et al, 1990;Leonova et al, 2010;Nadeem et al, 2011Nadeem et al, , 2012a. As the hydrolysis of grain P during germination is a major source of inorganic P to support the growing seedlings during early growth stages (Nadeem et al, 2011;2012b) therefore the present study was conducted to investigate the role of P nutrition to the parent plant on the dry weight and P reserves accumulation in maize grains for better selection of seeds.…”

“…Previous research showed that size of maize grain can influence the nutritional status (micro and macronutrients) of grains (Calderini & Ortiz-Monasterio, 2003;Baraloto et al, 2005;Hanley et al, 2007;Zhang et al, 2012) and consequently the growth of seedlings. Larger grains with larger nutritional reserves are capable of producing vigorous plants (Howe & Schupp, 1985;Ellison, 1987;Pommel et al, 1995;Nadeem et al, 2012a). Seedling emergence was more rapid in seeds with higher P concentrations compared to seeds with low P status (De Marco, 1990;Pommel et al, 1995).…”

“…Seedling emergence was more rapid in seeds with higher P concentrations compared to seeds with low P status (De Marco, 1990;Pommel et al, 1995). Crop grains have large enough P reserves to sustain seedling P requirement during a few weeks of early growth (White & Veneklaas, 2012), however grains with higher indigenous P reserves can support seedling growth for a longer period of time (Nadeem et al, 2012a) especially on soils with low inherent P levels. Higher P contents per seed were observed in basal grains in HP treatment.…”

Nutritional status of grains may vary due to external nutrient supply and their position within parent maize cob. Phosphorus (P) is the least mobile nutrient in the soil and therefore newly growing seedlings are largely dependent on the stored grain P contents which are accumulated during the crop maturity period. Objective of this study was to access the effects of different P applications and grain positions on P and dry matter contents in grains. Phosphorus application and grain position has significant (p<0.05) effects on P contents in grains whereas dry weight and P content are highly correlated. Grain weight and P contents decreased linearly from base to apical position possibly due to flow of nutrients from base towards apical position within cob. Significantly higher grain dry weight (0.35±0.01 g) and P contents (962±57 µg P) are recorded in high P application (92.50 kg ha-1) rate on base position whereas minimum grain dry weight (0.14±0.01 g) and P contents (219±11 µg P) were recorded on apical grain position in low P application (5.60 kg ha-1) rate. The results suggest that for better seedling P nutrition especially in soils of low inherent P, maize grains should be selected from base or middle position where maximum dry weight and P contents are concentrated to support the seedlings to reach at growth at which roots are capable of external P uptake.

“…We also recorded positive effects of P and K application on concentrations of P and K in the grain. Although P and K concentrations in barley grain have rarely been studied, they are believed to be highly important for the seeds for sowing as low concentrations of P and K in seeds in general can negatively affect the rapidity of germination and development of seedlings (Hejcman et al 2012a, Nadeem et al 2012, White and Veneklaas 2012.…”

“…For example an insufficient P concentration in seeds can negatively affect germination of seeds and growth of seedlings and therefore following yield of different crops (Hejcman et al 2012a, Nadeem et al 2012, White and Veneklaas 2012. High P concentration in seeds is thus highly important particularly for seeds for seeding.…”

Little attention has been paid to the effect of long-term fertilizer application on concentrations of elements in grain of barley produced on the metal non-contaminated agricultural soil. In 2010, we analyzed yield and concentrations of elements in grain of spring barley in unfertilized control, mineral fertilizer application (N 4 P 2 K 2 -70, 60 and 100 kg N, P and K per ha) and combinations of farmyard manure or poultry litter with mineral fertilizer (FMN 4 P 2 K 2 and PLN 4 P 2 K 2 ) treatments in the Ruzyně Fertilizer Experiment established on Luvisol in 1955 in Prague (Czech Republic). The yield of grain ranged from 4.03 to 9.74 t/ha in the control and FMN 4 P 2 K 2 treatment. There was a positive effect of fertilizer application on concentrations of nitrogen, phosphorus and potassium, but no effect on concentrations of calcium and magnesium. With the exception of iron, concentrations of micro (copper and zinc) and risk elements (arsenic, cadmium, chromium, lead, manganese and nickel) were not significantly affected by the fertilizer treatments. Long-term use of organic and mineral fertilizers with appropriate application rates does not represent any risk for contamination of barley grain by risk elements on mineral rich and metal non-contaminated agricultural soils.

Phosphorus (P) is the least mobile nutrient in the soil as compared to other macronutrients and therefore frequently limits crop growth. During germination and early growth, seed-phytate hydrolysis and seed-P remobilization is the major P source for developing seedlings. The objective of this paper was to investigate whether seed-P hydrolysis and remobilization of nonphytate P are sufficient for seedling P nutrition during early growth stages of maize. A large part of initial maize endogenous seed P reserves are mainly in the form of phytate. Till 70 cumulated degree days after sowing, nearly all the phytate (98%) was hydrolyzed and caused an increase in nonphytate P in seeds. Phytate hydrolysis and remobilization of nonphytate P was the main source of P supply for the newly growing seedlings and was not a limiting step for seedling P nutrition during the first four weeks of early growth.
