background & aim: in sustainable agriculture, organic fertilizers are considered as important alternatives for chemical ones and are of great importance in organic producing of medicinal plants. this study was conducted to study the effects of organic fertilizers on cassia angustifolia vahl in dry and subtropical climate.  experimental: this study was carried out in jiroft region, kerman (i...

A pot experiment was conducted to evaluate the effect of salinity on growth and heavy metal uptake by maize (Zea mays) plant. The results study show that NaCl NaCl+CaCl2 treatments decreased plant (plant height, shoot weight root weight) significantly. proportion viable roots fresh declined with time. In contrast, enhanced length. increased accumulation Cd, Zn Cu in considerably both root.

to study the effect of salinity stress on seed germination and seedling growth of four medicinal plants, nigella sativa l., cannabis sativa l., trigonella foenum graecum and cynara scolymus l. an experiment was conducted in the botany laboratory of islamic azad university, birjand branch. a completely randomized design (crd) with 3 replications was used as separately for each species. treatment...

Field microplot experiments were conducted from 1987 to 1992 to determine the relationship between fresh weight leaf yield of shade tobacco (Nicotiana tabacum) and initial density of Globodera tabacum tabacum (encysted J2 per cm(3) soil). Initial nematode densities of 0.1 to 1,097 J2/cm(3) soil were negatively correlated with leaf yield, total shoot weight, and normalized plant height 5 to 6 we...

Background: The composition of the planting beds and its microorganisms has a very important role on the establishment, growth and phytochemical performance of medicinal plants. Objective: The aim of this study was to determine the effect of different planting beds and inoculation of mycorrhizal fungus on the changes of stevioside, rebaudioside, and morpho-physiological traits of stevia. Meth...

This experiment was conducted to determine allopathic effects of Cyperus rotundus extracts on the tomato germination. It was a completely randomized design (CRD) with four replications, carried out in the laboratory of the Agricultural College of University Jiroft during 2011. The various test treatments were extracts of Cyperus rotundus taken from aerial organs, root, and com...

Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...
