wheat crop, considering its high planting area and consumption at national scale, demand a regular yield increase. humic acid, as an organic acid obtained from humus and organic sources without any environmental destructive effects, improves wheat yield particularly in variable environment conditions. in order to evaluate the effects of different levels of humic acid on shoot and wheat yield, a...
Salinity is one of the most important non- biological stresses which limit the production of agricultural yields in dry and semi arid regions. Humic acid as an organic acid and ascorbate as a powerful antioxidant can improve yield of plants under salt stress. In order to investigation effects of salinity and its interaction with ascorbate and humic acid on growth, photosynthetic pigments conten...
Factor analysis is one of the multivariate statistical techniques that considers the interrelationships between apparently irrelevant variables and helps researchers to find the hidden reasons for the occurrence of an event. In order to evaluate the effects of different irrigation levels and humic acid foliar application and identify the factors affecting water use efficiencies of sesame (Sesam...
In order to investigate the effect of vermicompost and humic acid on the quantitative and qualitative characteristics of safflower (Carthamus tinctorius L.), an experiment was conducted in a completely randomized design with seven treatments (control, 100 g vermicompost, 200 g vermicompost, 0.5 g.lit humic acid, 1 g.lit humic acid, 0.5 g.lit humic acid + 100 g vermicompost, 1 g.lit humic acid ...
Objective: In addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. Effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to...
in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

Growth analysis is a valuable and practical method on quantitative growth, development and crop production evaluation. In order to study the effects of granular humic acid and foliar application of compost tea and vermiwash on growth indices of safflower (carthamus tinctorius), an experiment was conducted as a factorial based on randomized complete block design with three replications in agricu...
Lily (Lilium longiflorum L.) is one of the most important potted flowers, which is used largely as cut flower. An experiment, arranged as a factorial besed on completely randomized dasign with three replications, was carried out to evaluate the effects of pre-harvest foliar application of humic acid, salicylic acid and calcium chloride on quality and longevity of lilium cut flowers. Treatments ...
