Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
In order to examine the effect of the quantity of Nitrogen fertilizer and bush density on vegetative and productive function of henna medicinal plant (Lawsonia inermis) factorial experimentation in the form of block plan was carried in three stages in agriculture research center in south of kerman province in corp of 2012. The first factor containing Nitrogen fertilizer in 4 levels i...
Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...
In recent years, special attention has been paid to the consumption of plant growth stimulants such as amino acids and humic acids along with micronutrients to adjust the effects of abnormal environmental conditions such as untimely cold or salinity and drought stress in grain production programs. In order to investigate the effect of growth enhancers on compensating for the lack of transport a...

in order to effects of fertilizer source and intercropping ratios on macronutrients concentration and uptake of fenugreek and black cumin, a factorial experiment was conducted as randomized complete block design with three replications at shahrekord university research farm in 2013. sole cropping of fenugreek (f) and sole cropping of black cumin (b) and three intercropping ratios (f:b 2:1, f:b ...
this research has been done for studying the effect of split application of nitrogen fertilizer on growth indexes and yield of three hybrids of grain corn in shahrood. a split plot experiment based on randomized complete block design with four replications was carried out in 2007. three hybrids of corn (double cross 370, single cross 447, single cross 499) were placed in main plots and split ap...
to evaluate the effect of time and level of nitrogen application on quantity and quality of two carrot varieties, an experiment was carried out in the framework of a 4×3×2 factorial and based upon a randomized complete block design of three replications. the levels of 25, 50, 75 and 100 kg / ha of nitrogen fertilizer were investigated within 3 applied times, namely: simultaneous with bed prepar...
Considering the importance of organic fertilizers application and the necessity of minimizing the use of inorganic fertilizers, this experiment was conducted in order to study the possibility of replacing vermicompost and poultry manure instead of chemical fertilizers in the production of two improved chickpea cultivars under dryland conditions. The experiment was laid out in a factorial arrang...
