“…For example, water was extracted from the uppermost layers of the soil profile first and then from progressively deeper layers as the profile dried; moreover, water was extracted more from deeper layers of the profile in N treatments (198 kg N ha −1 ) than in zero-N treatments (0 kg N ha −1 ) at Nabeul in the Cap Bon peninsula (Latiri-Souki et al, 1998). In our study, the amount of soil water consumption in N2 was significantly greater than that in other treatments in the 60-140 cm soil profiles in the period from 2012 to 2013 and in the 60-160 cm soil profiles in the period from 2013 to 2014 (Fig.…”

“…For example, Behera and Panda (2009) reported that the crop evapotranspiration (ET) in the 80 kg N ha −1 treatment was higher by 22 mm from 2002 to 2003, 28.3 mm from 2003 to 2004 and 37.3 mm from 2004 to 2005 than that in the 0 kg N ha −1 treatment under 40% maximum allowable depletion of available soil water. Moreover, the response of crops to N fertilisation is dependent on soil water status, amount and frequency of precipitation during the growing period of crops, more than amount and timing of N applications (Latiri-Souki et al, 1998;Tilling et al, 2007). In the semiarid Loess Plateau in China, Guo et al (2012) reported that the optimal N fertilisation rates in dry, normal and wet years were 45, 135 and 180 kg ha −1 , respectively, in a rain-fed winter wheat cropping system.…”

“…Nitrogen is one of the most important macronutrients that are used highly in today's input agriculture (Latirisouki et al, 1998 [7]; Lawlor, 1995 [8]). Nitrogen at the cellular level increases the number and size of cells and increases the leaf area and the efficiency of radiation absorption by plant (Jenkyn and Luch, 1998 [9]; Marbet, 2000 [10]).…”

To study the effects of different levels of nitrogen fertilizer on yield and yield components of cultivars of rainfed wheat a study was done in the crop year 2012-2013 as factorial in a randomized complete block design with 3 replications, in 2 research stations of Kohne Kand city in Bojnord and Shirvan dryland research station. The treatments of study contain cultivars of wheat in 4 levels (Rasad, Sabalan, Cross Sabalan and Azar 2) and 4 levels of nitrogen fertilizer (75, 50, 25 and 0 kilograms nitrogen per hectare). The results showed that the yield in Shirvan was significantly higher than that in Bojnoord. Moreover, the impact of cultivar and nitrogen on yield and yield components was significant in both regions and among different cultivars Azar 2 has the highest yield in both regions and the lowest yield was for cross Sabalsn in Shirvan and Sabalan in Bojnoord. Furthermore, yield increased by increasing the nitrogen in both regions but there was no significant difference between levels 50 and 75 kilograms per hectare. Among yield components except the number of spikes per square meter, others had a high correlation with yield.

“…Relatively strong growth, in terms of plant height, leaf number and stem width in response to higher N treatments, suggest that the increased growth is not directed only towards apical dominance but rather generates increased biomass. N is generally linked to increased dry matter production (11,12) and the production of vegetative growth over reproductive growth (13) or secondary metabolite formation (14).…”

Perennial horticulture centre, tasmanian institute of agriculture, university of tasmania, hobart, tasmania, australia ABSTRACT Developing systems for the commercial production of native plant species is required to ensure a sustainable supply of quality material. The aim of this study was to examine the influence of key nutrients on the early establishment of Tasmannia lanceolata for potential plantation production of leaves from which polygodial is extracted. Treatments of N, P and K fertilizers were imposed on a single clone in a pot trial with a factorial design. Levels of all other essential nutrients were kept constant. The highest application level of N (20 mM, 2.32% N in leaves) achieved the highest level of polygodial as a percentage of dry matter. The highest P (2 mM, 0.42% P in leaves) and K (12 mM, 1.73% K in leaves) treatments produced a noticeable decline in total polygodial yield, with mediumlevel treatments of both nutrients producing the highest levels of polygodial. The implications of these findings for the production of commercial quantities of T. lanceolata leaf material are discussed.
