“…The N-uptake in maize due to N fertilization and the relationship between dry-matter yield and N uptake was in accordance with our previous study (Abbasi et al, 2010(Abbasi et al, , 2012. High above ground dry matter yield has been shown to correlate strongly with total above ground N uptake in tropical maize populations (Azeez et al, 2006). Results of this study also demonstrated that both straw and grain yield in our conditions depended upon the growth characteristics and N balance of maize.…”

“…Relative yield increments in response to N fertilization ranged between 28 and 39% over the control. Increments in maize straw yield by N fertilizers were also reported earlier under different soils and environmental conditions (Abbasi et al, 2012;Azeez et al, 2006;Barbieri et al, 2008;Hammad et al, 2011).…”

“…The LA of maize was reported to increase with increasing N rates from 120 to 180 kg N ha −1 in Khyber Pakhtunkhwa, Pakistan (Amanullah et al, 2009). The application of low N rates (0, 30, 60, and 90 kg N ha −1 ) on maize in a tropical Alfisol in northern Nigeria increased LA from 543 to 2957 cm 2 , and N rates of 60 and 90 kg ha −1 showed the same values (Azeez et al, 2006). The effect of N fertilization in enhancing LA is well documented in maize because of the higher photoassimilates that result in more dry matter accumulation (Marschner, 1995; Uhart and Andrade, 1995).…”

“…Selection of the most appropriate N fertilizer rate is a major concern for economic viability, crop productivity, and environmental quality. Increases in maize growth and yield due to N fertilization is well documented in different parts of the world (Azeez et al, 2006; Barbieri et al, 2008; Riedell et al, 2009; Amanullah and Shah, 2010). Application of 250 kg N ha −1 has been reported as an optimum rate of N for maize under the semiarid environment of Pakistan (Hammad et al, 2011).…”

Yield and Nitrogen Use Efficiency of Rainfed Maize Response to Splitting and Nitrogen Rates in Kashmir, Pakistan

Effi cient use of N for maize (Zea mays L.) production is an important management strategy for increasing crop yield and improving N use effi ciency (NUE). A 2-yr (2007 and 2008) fi eld experiment was conducted to evaluate the eff ect of timing and rate of N application on growth and yield, N uptake, and NUE of rainfed maize. Th e experiment was a randomized complete block design with split-plot arrangement using three replications. Treatments consisted two application timings-full dose of N at planting or a split application, with half at sowing and half at V6 stage-and seven N rates of 30, 60, 90, 120, 150, 180, and 210 kg N ha -1 and a control. Results indicated that N fertilization increased straw yield by 34 and 27% and grain yield by 88 and 80% in 2007 and 2008, respectively, over the control. Th e maximum grain was recorded for 180 kg N ha -1 . Splitting N did not show a signifi cant eff ect in 2007 but displayed a signifi cant increase in both straw and grain yield (6%) over full N application in 2008. Th e maximum N uptake ranged between 122 and 139 kg N ha -1 and required 180 kg N ha -1 (except split application in 2007). Splitting of N signifi cantly increased N uptake by 6 and 13% (2007 and 2008, respectively). Th e maximum NUE was observed between 68 and 70% at 90 kg N ha -1 and there was a general trend of decreasing NUE with increasing N rates. Splitting N increased NUE by 14% (2008). Results of this experiment showed that application of 180 kg N ha -1 in split applications is a successful and sustainable management strategy for maize production in rainfed mountainous ecosystems.

“…Environmental and soil factors such as air temperature, precipitation, atmospheric CO 2 concentration, and nutrient availability affect crop phenology, growth and development. Inherent soil nutrient status and nutrient fertilization (i.e, location and cultivar specific) limits the maize yield (Azeez et al, 2006). Nitrogen is one of the most important nutrients required by maize plants in large quantities for completion of its life cycle.…”

The present investigation was carried out to access the optimal N dose and its impact on growth, yield and yield attributes of hybrid maize (Zea mays. L) under subsoil compaction condition. The experiment was conducted at Research Farm, Department of Soil Science, Punjab Agricultural University, Ludhiana during the summer seasons of the year 2012 and 2013. The experiment comprised three subsoil compaction treatments in main plots and three nitrogen levels in sub plots following split-plot design with three replications. Plant height, leaf area index and dry matter accumulation were negatively affected by subsoil compaction. However nitrogen fertilization mitigates the negative effect of subsoil compaction on growth of maize. Cob length was recorded lower with higher cob barrenness under higher degree of subsoil compaction. The grain yield was reduced by 13-16 per cent and biomass yield by 10-17 per cent due to subsoil compaction. The total N uptake was 14.6 and 18.2 per cent higher under C 0 treatment than that in highly compacted subsoil (C 2 ), while N 2 treatment had improved the total N uptake by 18.6 and 14.9 per cent as compared to N 0 treatment during the year 2012 and 2013, respectively. The results revealed that N 1 fertilization level can be recommended under subsurface compacted soils as compared to N 0 and N 2 rates. This study further suggests the management option should be explored in addition to deep tillage to maximize yield of maize.
