the main objective for plant breeding is to increase genetic diversity. mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. the present research was aimed to compare efficacy of different doses of gamma rays (150, 200, 250, 300 and 350 gy and zero dose control) on the sesame morphological ...

recently, biofertilizer application is growing to meet sustainable agriculture goals. the present experiment was designed to evaluate four nitrogen levels (0, 60, 90 and 120 kg n.ha-1) as main plots, two supernitroplus biofertilizer levels) with and without biofertilizer) as sub-plots on yield and yield components of three sesame cultivars (naz, oltan and varamin (as sub-sub-plots in a split-sp...

this research was investigated to study relationship among seed yield, seed yield components and morphological traits and their direct and indirect effects on seed yield of 100 safflower genotypes in two water environments (normal and drought stress) at research farm of isfahan university of technology during 2012. seed yield had positive correlation with number of head per plant, seed per head...

in order to investigate the effect of seed rate on seed yield and yield components of three rapeseed varieties, a split- plot experiment was conducted in randomized complete block design with four replicates during 2008-2009 at baykola agricultural research station, neka, mazandaran province. in this experiment four seed rates (5, 7, 9 and 11 kg.ha-1) as main plots, three rapeseed cultivars (hy...

in order to study the effect of spraying of abscisic acid on yield and yield components of chickpea (cicer arietinum l.) under rainfed and supplementary irrigation, a field experiment was conducted in 2010 in agricultural research station of ilam university. a split factorial experiment based on a randomized complete block design was conducted. main plots were composed of two levels of irrigati...

in order to investigate lentil response to application times and amounts of zinc, an experiment was arranged as factorial based on randomized complete block design with four replications on farm research of gonbad higher education center during 2008-2009. treatments were application times (before flowering and beginning of pod setting) and application rates (0, 0.5, 1, 1.5 and 2 liter per hecta...

Water stress and soil nutrients affect the growth of medicinal herbs as well as the quantity and quality of their essential oils. The effect of drought stress and different fertilizers on yield and morphological traits of Ajowan was studied in a split-plot experiment on the basis of a Randomized Complete Block Design with three replications in Qaen, Iran. The main plot was devoted to irrigation...

introduction fertilizers are the key components which provide plant nutrients' needs in recent years (omid jangir & sing, 1996; kapoor et al., 2007). in many cases, using chemical fertilizers has different negative environmental effects such as soil, water and air pollution, which increase environmental hazardous and production costs (jangir & sing, 1996; kapoor et al., 2007). biological activi...
