Canna indicaL.roots are used for medicinal purpose. A decoction of the root with fermented rice is used in the treatment of gonorrhea and amenorrhea. The seed of canna is extremely hard, and needs to be "scarified" before sowing. The aim of the present investigation is to determine the hardiness problem of the seed. The seed sample was collected from the IARI, New Delhi in 2008. The wo...

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...

the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...

parsley has a very high nutritional value, containing a, b and c vitamins and mineral nutrients. in order to investigation of the effect of different nitrogen sources on parsley an experiment conducted in a factorial combination of three nitrogen forms (calcium nitrate, ammonium sulphate and urea) and four nitrogen levels (0, 100, 125, 150 kg ha-1) by using a factorial experiment based on rando...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

the superabsorbent polymer withholding water and disperse it gradually to roots increase soil water capacity. to study the effect of superabsorbent polymer on decreasing water stress effect as well as increasing irrigation efficiency a factorial experiment based on randomized block design with 4 replicates was design. treatments were 0, 10 and 20 % v superabsorbent and irrigation levels 25, 50 ...

Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...

     Due to the environmental problems caused by the accumulation of significant amounts of waste from peanut cultivation, it seems necessary to provide a solution for the reuse of this organic waste. Therefore, this experiment was conducted to investigate the possibility of using compost of peanut shells in potting Begonia rex. This research was based on randomized complete block desi...
