“…In the case of N application strategies, during 2010 and 2011 maximum grain protein content was recorded by using the N 3 . these results are related to the finding of Thomison et al (2004) and Gallais et al (2008), who reported that N application by different methods and at different timing had significant effect on grain protein content. However, reduced grain protein content was obtained in N 5 .…”

Nitrogen (N) is one of the major limitations to crop productivity. Therefore, a field study was conducted to examine the impacts of N application strategies: N 1 -20% of N at sowing through broadcast + 79% N at mid-season through fertigation + 1% of N at flowering through foliar application, N 2 -40% of N at sowing through broadcast + 59% of N at mid-season through fertigation + 1% of N at flowering through foliar, N 3 -60% of N at sowing through broadcast + 39% of N at mid-season through fertigation + 1% of N at flowering through foliar, N 4 -80% of N at sowing through broadcast + 19% of N at mid-season through fertigation + and 1% of N at flowering through foliar and N 5 -100% of N at sowing through broadcast, on the productivity of maize hybrids (H) single cross-6142 (H 1 ) and double cross-4444 (H 2 ) over a 2-year period, 2010-2011. During both years, N strategies and maize hybrids differed significantly for all the observed traits of yield and quality. The highest biological yield (16.99-17.62 t ha -1 ) and grain yield (6.83-7.16 t ha -1 ) were recorded by using the strategy N 3 . Similar trends were also observed for other traits except the grain oil content which was the maximum (3.38-3.98%) at N 5 . However, in both years, maximum biological yield (14.83-15.69 t ha -1 ) and grain yield (5.01-6.02 t ha -1 ) were evident in H 1 . the interactive effect of H 1 × N 3 gave maximum biological yield (17.55-20 t ha -1 ) and grain yield (7.53-8.83 t ha -1 ). In 2010 and 2011, the highest net income (1220-1272 USD ha -1 ) and benefit cost ratio (2.52-2.56) was also attained at H 1 × N 3 . In conclusion, our results suggested that maize productivity (grain yield up to 5.01-6.02 t ha -1 ) could be improved on economic basis (benefit cost ratio up to 2.52-2.56) by growing the single cross hybrid-6142 (H 1 ) with N application strategy N 3 .

“…This trend was not unexpected since higher grain protein content has been linked to increasing nitrogen fertility (Lambert et al 1998;Thomison et al 2004). At Elora, no differences (P 0.05) between the nitrogen fertilizer levels were observed in either 2001 or 2002 and were regressed into single lines.…”

Nitrogen availability is often a limiting factor for optimum crop growth on agricultural soils amended with papermill biosolids (PB). The objective of our study was to evaluate the effect on corn (Zea mays L.) and soybean (Glycine max L.) production of adding supplementary nitrogen fertilizer to soils amended with increasing rates of PB. Papermill biosolids were applied annually on four agricultural soils in southern Ontario, Canada. Treatments included three rates of PB (50, 100, and 150 Mg ha-1), combined with four levels of nitrogen fertilizer [crop recommended [CR], [CR] + 0.5 kg N Mg-1 PB, [CR] + 1.0 kg N Mg-1 PB, and [CR] + 1.5 kg N Mg-1 PB]. In addition, non-amended plots were also established receiving either (a) zero PB and zero nitrogen fertilizer or (b) zero PB and [CR] nitrogen fertilizer only. All the plots received the same treatment combinations, i.e., PB × N, each year for the duration of the study. In corn, [CR] nitrogen fertilizer was insufficient to satisfy plant growth and PB decomposition requirements. Supplementary nitrogen fertilizer at a rate of 1.0 kg N Mg-1 PB was generally required to maintain or increase corn grain production relative to the control plots receiving the [CR] nitrogen fertilizer only. Corn grain yield increases ranged from 1000 to 6000 kg ha-1 relative to the control at some of the research sites. The optimum rate of supplementary nitrogen fertilizer varied by soil texture (location) and year. In contrast, production of soybean did not require high supplementary nitrogen fertilizer, or in some cases any, in order to maintain or increase yields at most locations. Our study shows that nitrogen fertility management had a greater impact on yields in production systems planted to corn than soybeans while receiving annual PB amendments. No residual effects on corn yield or corn grain protein content were observed after PB amendments were stopped.Key words: Papermill biosolids, carbon:nitrogen ratio, corn, soybean, nitrogen fertilizer

“…In Jellum et al found that increasing nitrogen application rate had no influence on the oil concentration of corn grain [26]. According to Thomison et al grain oil concentration, averaged across hybrids and N treatments, in maize were 6.0, 6.5 and 6.4% in 2000,2001, and 2002, respectively [21]. Among the maize genotypes, the maize hybrid (P-3025) had significantly (P ≤ 0.05) higher SOC than the two local cultivars (Azam and Jalal) in both years (Table 3), although the differences in the SOC of two local cultivars were not significant.…”

“…In Argentina, even for the same genotype cropped under nonlimiting N conditions in the field, grain protein concentration varied drastically among the years from 60 to 120 g kg -1 [20]. According to Thomison et al grain protein concentration, averaged across hybrids and N treatments, in maize were 9.2, 7.5, and 9.4% in 2000, 2001, and 2002, respectively [21]. The relatively low percent grain protein in 2001 was attributed to protracted wet soil conditions during the spring, which favored loss of N through denitrification and leaching.…”

“…Among the maize genotypes, the maize hybrid (P-3025) had delayed PM, increased SPC, SOC, SSC and TSW than the two local cultivars (Azam and Jalal) and was confirmed the most efficient genotype than the two local cultivars because of its positive response to the all three sources and levels of N. Jalal stood second, but Azam because of its early PM, ranked in bottom in terms of its lowest SPC, SOC, SSC and TSW and was considered the least efficient genotype in this study. Grains of maize hybrids containing nutritionally enhanced genetics may exhibit higher oil and crude protein profiles than normal field maize [21]. In Fageria et al suggested that in the 21 st century, nutrient efficient plants will play a major role in increasing crop yields compared to the 20 th century, mainly due to limited land and water resources available for crop production, higher cost of inorganic fertilizers, declining trends in crop yields globally, and increasing environmental concerns [8].…”

Field experiments were conducted during summer 2008-09 (Y1) and 2009-10 (Y2) at the Agronomy Research Farm of The University of Agriculture Peshawar-Pakistan to investigate the impact of different N-fertilizer sources [urea, calcium ammonium nitrate (CAN) and ammonium sulphate (AS)] and their levels (50, 100, 150 and 200 kg ha -1 ) on phenology, seed weight and composition (seed protein, oil and starch content) of maize (Zea mays L.) genotypes "Local cultivars (Azam and Jalal) vs. hybrid maize (Pioneer-3025)". The results revealed that the rest (all the experimental plots applied with N) had delayed phonological development and had produced heavy grains with higher protein, oil and starch contents over control (N not applied). In both years, the maturity was delayed, seed weight and seed protein content increased with the application of two higher N rates (150 and 200 kg ha -1 ) as compared with the two lower N rates (50 and 100 kg ha -1 ). Applications of N in the form of ammonium sulphate enhanced maturity and decreased seed weight but increased seed oil content over urea and calcium ammonium nitrate. The maize hybrid (P-3025) with delayed maturity produced heavy seeds and higher seed protein and oil contents as compared to the two local cultivars (Azam and Jalal). The hybrid (P-3025) was considered the more efficient maize genotype that responded very well to different sources and rates of N than the local maize cultivars.
