Effect of humic acid and mulches on some characteristics of tall fescue (Festuca arundinacea Schreb.)
Application of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality. However, limited research has investigated their effect on lawn establishment. To investigate the effect of humic acid and selected mulches on characteristics of Festuca arundinacea in its planting stage, a factorial experiment based on a completely rando...
متن کاملEffect of salicylic acid and humic acid on some physiological characteristics and yield of forage maize (Zea mays L.) under drought tension conditions
In order to investigate the effect of salicylic acid and humic acid to mitigate the impact of drought tension during pollination of forage maize, the present experiment was conducted as split plots based on randomized complete blocks design with three replications at Isfahan University of Technology. Drought tension levels included: without tension (control), mild tension (75 percent crop capa...
متن کاملEffects of humic acid on changes in nutrient concentrations of leaf, root and stem nutrients of Satureja khuzestanica under salinity stress
To investigate the influence of humic acid on the amount of absorption and allocation of elements to different parts of Satureja khuzestanica under salinity stress conditions, a greenhouse experiment was done as factorial based on a randomized complete block design in four replications. Factors included humic acid (zero, 10, 20, 30 and 40 mg kg-1 soil), and salinity stress (zero, 25, 50, 75 and...
متن کاملEffect of humic acid and mulches on characteristics of tall fescue (Festuca arundinacea Schreb.)
Application[Editor 321] of biotic growth regulators (e.g. humic components) and appropriate mulches is recommended to improve turfgrass quality especially in arid andsemi-arid climate zones. However, limited number of studies have investigated their effect on lawn establishment. To investigate the effect of humic acid (HA) and selected mulches on characteristics of Festuca arundinacea in its p...
متن کاملEffects of Humic Acid on Root and Shoot Growth and Leaf Nutrient Contents in Seedlings of Pistacia vera cv. Badami-Riz-Zarand
Humic acid is a biochemical constituent of humus and increases root biomass and shoot growth by improving absorption of nutrients. In order to study the effects of humic acid on root and shoot growth and leaf nutrient contents of pistachio seedlings, an experiment was conducted of completely randomized design with five treatments in three replications. In the first step seeds of Pistacia vera c...
