Background & Aim: Cassia angustifolia Vahl is a valuable medicinal plant that it is important for constipation treatment. According to the importance of organic agriculture in increasing the yield of medicinal plants, the effect of bio-fertilizer on quantities yields of Cassia angustifolia Vahl or Senna in Karaj region (Iran) was examined. Experimental: This research was carr...

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 this study, the effect of irrigation regimes and plant nutrition were evaluated as split plot arrangment based on randomized complete block design with three replications in 2010. treatments consisted of irrigation regimes at three levels: well-irrigation, irrigation disruption at vegetative growth stage, and irrigation disruption at reproductive growth stage as main plots and combination of...

The Haber–Bosch process for the commercial production of ammonia demonstrated in 1913 was a watershed event in the mass production of urea, the principal nitrogen fertilizer for modern agriculture. Today, thanks to the so-called “green revolution” starting in in the 1960s, nearly half of the world population relies on increased crop yields, through the use of nitrogen fertilizers, to access aff...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...

a split plots experiment based on randomized complete blocks design was carried out at field research center of islamic azad university, shoushtar branch during 2012 to find out the suitable sowing date and urea fertilizer used in chamomile (matricaria recutita). main plots including three sowing date (9, 19 and 29 february 2012) and subplots including four levels of urea fertilizers (5, 10, 15...

in order to study the effects of vermicompost and biological fertilizers on vegetative yield and essential oil of basil (ocimum basilicum l.), an experiment was conducted based on a complete randomized block design with nine treatments and three replications at mashhad during growing season of 2009-2010. the treatments were: 1) vermicompost, 2) nitroxin (included: azotobacter sp. and azospirill...

salicylic acid (sa) is a phyto-hormone that regulates physiological and biological processes in plants and can be used to improve plant growth under different environmental conditions, including water stress. thus, a field experiment as split plot factorial based on randomized complete blocks design with three replications was conducted in 2014 to investigate the effects of fertilizer and salic...

In order to evaluate the different growing media and nitrogen fertilizer (urea) on some morphological traits of Spathiphyllum plant, an experiment was carried out in split plot arrangement based on completely randomized design in three replications in greenhouse conditions in 2018. The main plot consisted of different growing media including T1: Leaf-mold, T2: Vermicompost and T3: A mi...
