in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...
An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...
an experiment with randomized complete block design with 3 replications was carried out in the rice research institute of iran, rasht, during 2008 to study the effect of supplement foliar application of nitrogen (5% n) and potassium (3% k2o) at different growth stages (maximum tillering stage, booting stage, and both of them) on grain quality and nitrogen efficiency of hybrid rice, c.v. bahar-1...
in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...
The present study aims to investigate the effects of nitrogen fertilization and municipal waste compost on yield, yield components and some of the grain macronutrients of sweet corn. A field experiment was carried out as a split plot in randomized complete block design with three replications in 2015 at Agriculture and Natural Resources Research Center Zarghan-Fars, Iran. The main plot consiste...
in order to evaluation the effects of different soil fertility systems on chickpea seed quality, field experiments were carried out in sanandaj agriculture research station of iran in 2007 and 2008 growing seasons. experimental units were arranged in split-split plots based on randomized complete blocks with three replications. green manure levels considered main plots, base fertilizer compound...
For investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the Research Field of Islamic Azad University, Jiroft, Iran in 2013-2014. The main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of ...
In order to evaluate the effect of concentration and time of foliar spraying of nitrogen fertilizer as complementary of soil nutrition on dry matter remobilization and seed and oil yield of rapeseed (Hyola401), an experiment was conducted in complete randomized block design with 16 treatments and three replications in two years (2008-2010) in Rice Research Institute of Iran (Rasht). In this exp...
In order to study the effect of application of nitrogen, phosphorus and biologic fertilizers on yield and yield components of native bean, an experiment was conducted as factorial in randomized complete block design with three replications in Lahijan, northern Iran in 2013. Treatments consisted of chemical nitrogen fertilizer (0, 60 and 120 kg ha-1 urea), chemical phosphorus fertilizer (0, 40 a...
in order to investigate the effects of nitrogen application rates and different planting beds on yield and yield components of garlic (allium sativum l.), a field experiment was conducted as split plot based on a randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, iran, during 2009-2010. three nitrogen application rates ...
