“…There was linear increase in plant stand with increased seed rate and the highest seed rate gave significantly higher plant stand, followed by next rates. These findings are in agreement with the reports of Bekele et al (2002) and Iqbal et al (2010) who reported that increasing seed rates resulted in increased plant population.…”

The effect of seed rates on yield and yield components of linseed were studied in South-Eastern Highlands of Ethiopia at four locations during 2012/13 and 2013/14 which are main-cropping seasons. Randomized complete block design with three replications was used for row planting and 10m by 10m plots were used for broadcasting. The linseed variety 'Kulumsa-1' was used and sown at seed rates (kg/ha) of nine levels for row planting and six seed rate (kg/ha) levels were used for broadcasting. Results showed significant (P≤0.05) effects of seed rates were observed on all yield components reflecting the importance of seeding rate for linseed growth, yield and yield components. However, significant (P≤0.05) effects of seed rates were not observed on all yield components except on number of pods/plant in the case of broadcasting. The highest seed yield was recorded from 40kg/ha (2019kg/ha) and 70kg/ha (1908kg/ha) for row planting and broadcasting, respectively. This data depicted that 6% (111kg/ha) seed yield advantage was obtained by using row planting method as compared to broadcasting. Similarly by using 30kg/ha and 40kg/ha seed rates increased seed yield/ha by 6% (110kg/ha) and 9% (162kg/ha), respectively as compared to 15kg/ha in the case of row planting. Similarly, using 70kg/ha seed rate for broadcasting resulted in 6% (102kg/ha) and 7% (126kg/ha) seed yield advantage as compared to 30kg/ha and 40kg/ha seed rates, respectively. The results of economic analysis indicated that the highest net benefits were obtained by using a seed rate of 30 to 40kg/ha for row planting and 70kg/ha for broadcasting.

“…Also, many authors reported that increasing N level increased PH (Ali et al, 2000;Sobh et al, 2000;Jan et al, 2002;Iqtidar et al, 2006;Ali et al, 2011), SL (Ali et al, 2000;Asif et al, 2009;El-Gizawy, 2009;Ali et al, 2011;Iqbal et al, 2012;Gheith et al, 2013), NSS (Modhej et al, 2008;Ali et al, 2011;Iqbal et al, 2012), WGS (Noureldin et al, 2013), TGW (Ali et al, 2000;Iqtidar et al, 2006;Ali et al, 2011;Abedi et al, 2011) and NS m -2 (Ahmed Seham et al, 2009;Ansar et al, 2010;Njuguna et al, 2010;Abedi et al, 2011;Iqbal et al, 2012). Many studies have shown that the best yields achieved with 70 to 120 kg N ha -1 (Teixeira Filho et al, 2007;2010;Njuguna et al, 2010;Espindula et al, 2010;Abedi et al, 2011;Iqbal et al, 2012;Noureldin et al, 2013). High yields achieved in the control can be attributed to the high content of organic matter and humus in the soil in which they conducted experiments, since in the process of mineralization, which is more intensive in terms of sufficient amounts of rainfall and higher air temperatures in March and April, a significant amount of available N for plants is released (Cabrera et al, 2005).…”

Managing N inputs in wheat production systems is an important issue in order to achieve maximum profitable production, and minimum negative environmental impact. The aim of this investigation carried out in dry land farming in the Vojvodina province (Serbia) was to estimate the effects of different N fertilization levels (0, 75, and 150 kg N ha -1 ) on some quantitative traits, rain-use efficiency (RUE), N agronomic efficiency (NAE), and N use efficiency (NUE) in two Serbian winter wheat (Triticum aestivum L.) cultivars 'Pobeda' and 'Renesansa'. 'Pobeda' had higher grain yield (4437 kg . NAE and NUE declined at high N rates. Based on the results of this study, farmers should be advised that the use of large amounts of N increases production costs and reduce the economic benefits. The increase in wheat production is possible by selecting adapted genotypes with improved NUE.

“…Consequently, getting more crop production, N application is essential in the form of chemical fertilizer (Ali et al, 2000). Nitrogen is applied to the crop for higher vegetative growth, productivity and quality (Gwal et al, 1999 andIqbal et al, 2012). Balanced use of N is a key point for higher land profitability and healthy environment.…”

Nitrogen is recognized as one of the most limiting nutrient for crop growth in Bangladesh and can be supplemented with inorganic fertilizers like urea. The experiment was conducted in the net house of the Department of Agricultural Chemistry, Bangladesh Agricultural University during March to July 2012. The objective was to examine the effects of different levels of N on the growth, leaf biomass yield, N content and to estimate minimum N requirement and critical N content of stevia. The treatments included six N rates (0, 100, 150, 200, 250 and 300 kg ha -1 ). Plant sampling was done at 15, 30, 45 and 60 days after planting (DAP) to measure plant height, number of branches and leaves, fresh and dry weight of leaves, leaf area and N concentration. The results revealed that all the characters were significantly affected by different N rates. The highest values of all parameters except plant height and N concentration were obtained from 250 kg N ha -1 and the lowest values from N control. Nitrogen application at all levels increased leaf dry yield at harvest by 99 to 505% in acid soil and 69 to 438% in noncalcareous soil, respectively over control. The growth of most parameters was rapid at the later stages (30 to 60 DAP). Leaf N content proportionately increased with the increasing rates of N. The highest N concentration was obtained from its highest application (300 kg N ha -1 ). The minimum amount of N for maximum leaf biomass production in the plants grown in acid and non-calcareous soils was estimated to be ca 273 and 257 kg ha -1 , respectively. The critical N concentration to achieve 80% of the maximum production of stevia leaf was also estimated to be ca 1.43 and 1.50% in the leaves of stevia plants grown in acid and non-calcareous soils, respectively.
