this experiment was conducted in order to study the influence of different levels of municipal solid waste compost and nitrogen rate on grain quality of sweet corn (zea mays l. saccharata) and some soil properties under marvdasht conditions during growing season of 2008-2009. the experiment was arranged as split plots based on a randomized complete block design with two factors and three replic...

In the present study, some nutritional imbalances, specific ion toxicity and yield-ion concentration relationships in maize under water, nitrogen (N) and salinity stresses were assessed. Effect of different levels of irrigation water (I1=1.0ETc+0.25ETc as leaching, I2 =0.75I1 and I3 =0.5I1) as main plot, salinity of irrigation water (S1=0.6, S2= 2.0 and S3=4.0 dS m-1) as sub-plot and N fertiliz...

a study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (ocimum basilicum l.). the research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. the experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

The field investigation was carried out for two years at the Students’ Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana during spring season 2018 and 2019. experiment laid in a split plot design with four levels gypsum (0, 125, 175 225 kg ha-1) combination application stages (full sowing 50 % + flower initiation stage) main three nitrogen phosphorus (15 N ha-1 20 ...

background and objectives: soybean is one of the plants that need large amounts of nitrogen for grain yield production. todays bio-fertilizers are considered as a best replacement for chemical nitrogen to increase soil fertility and sustained agricultural production. meanwhile, the use of soybean symbiotic bacteria and nitroxin, which contain the most effective nitrogen-fixing bacteria of the g...

in order to study the influence of nitrogen and different harvesting dates on sorghum yield, a split plot experiment based on randomized complete block design was conducted with three replications in 2010 at the research farm of islamic azad university, ardabil branch. factors were: different harvesting dates in three levels containing, beginning of flowering, two and four weeks after beginning...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 kg N.ha-1 each) for Yazd location )0, 43.5, ...
