Seed enhancement methods are applied to eliminate or decrease adverse environmental stresses effects and increase seed germination rate and vigor of rangeland plants. The aim of this study was to assess different methods of seed coating effects on germination speed of Onobrychis sativa at different sowing depths and soil moisture levels. The experiment was conducted at growth chamber to apply a...

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing t...

although water deficiency has been seriously taken up as a subject in reducing crop production in arid and semi–arid areas, nevertheless little information has been published regarding its effects on seed quality. to evaluate the effects of irrigation regimes (full irrigation (control), irrigation until flowering stage, irrigation until doughing stage and irrigation until eight-leaf stage) on g...

The present investigation was carried out to study the induced mutagenesis of EMS (Ethyl methane sulphonate) on the seed germination, seedling survival and LD50 value of Catharanthus roseus. The seeds of Vinca rosea were treated with different concentration of EMS viz., 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 mM. The untreated seeds were taken as control. The EMS treated and control seeds were...

augment of germination rate is important in seedling establishment and crop yield. a set of study in laboratory & field conditions at agronomy department of university of tehran was conducted during 2004-2005. in lab. experiment the effects of seed priming was evaluated on germination indices (germination percentage and rate) of chickpea genotypes in a factorial experiment of 4×3×2 arranged in ...

Seeds of Balanites aegyptiaca stored for one year were germinated using cold and boiling water pre-treatments and different sowing orientations. Whole fruits were soaked in cold water for (18, 24 and 48 hours, respectively), while extracted sun dried seeds were immersed in boiling water for 7 minutes. Seeds of each treatment were sown in three orientations (seeds laid vertically with stalk end ...

A two-year field experiment was conducted at Regional Agricultural Research Station, Jessore during the rabi seasons of 2002—2003 and 2003-2004 to find out the level of disease incidence under different levels of irrigation and fungicide spray on the bulb yield of onion. Four irrigation levels: no irrigation (I1), irrigation at 10 days interval (I2), 20 days interval (I3), and 30 days interval ...

In North West India ground water is depleting because of adoption rice-wheat system. Therefore for saving precious resources there need to diversify some area under low requiring crops and adopt techniques. A field experiment was conducted evaluate individual interactive effects deep tillage, irrigation nitrogen rates on yield productivity canola (Brassica napus). Experimental treatments in mai...
