to investigate the effect of spraying with different concentrations of vermiwash solution on the morphological traits, percentage and yield of essential oil of lemon balm (melissa officinalis l.), this experiment was conducted as randomized complete block design (rcbd) with four replications in experimental field of agricultural faculty of ferdowsi university of mashhad (fum). the treatments we...

abstract salinity is one of the major abiotic challenges influencing plant productivity worldwide. to examine the response of two alfalfa cultivars (bami and hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mm l-1 nacl), a glasshouse experiment was conducted at the college of agriculture, shiraz university, shiraz, iran in 2008. the results showed that in bami (which appeared...

Studies were conducted to characterize the effect of advanced potato (Solanum tuberosum L.) seed-tuber age on plant growth potential and whole-plant morphology. Plant growth from single-eye seedcores from 5- to 18-month old ;Russet Burbank' seedtubers was compared. Loss in apical dominance was apparent with advanced age. On a per-core basis, the amount of plant dry weight was equal for the two ...

In the present investigation attempts were made to estimate genetic parameters for yield and its components in 315 genotypes of cocoyam collected from thirteen aroid growing districts. Plant height, petiole length, petiole breadth, leaf number, leaf length, leaf breadth, LAI, Inflorescence length, peduncle length, spathe length, spathe breadth, corm length, corm breadth, cormel number, cormel l...

According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...

in the present study, effect of five isolates of trichoderma harzianum on growth parameters of tomato was carried out as cr design with six replications under greenhouse conditions. the concentrations 0.5%, 1% and 1.5% inoculums per pot were used. plant length, shoot and root fresh/dry weight, number of leaves and stem diameter as growth parameters were measured. the results showed that isolate...

Background: The aim of this study was to examine the resource allocation among the organs and the leaf morphology of Polygonatum humile. The data were collected from June 2014 to May 2015 in a natural P. humile stand of a temperate forest gap. Results: The dry weight of new rhizome (R0) sharply decreased to the time of new shoot sprouting in next year and was constant for 2 ~ 3 years. However, ...

salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...

in order to evaluate the effects of different levels of water and plant density on yield, yield components, morphological and physiological characteristics of a new corn hybrid (ksc 500), an experiment was carried out in 2006 in karaj area. the experimental design was split plot based on randomized complete blocks design with three replications. main plots were three irrigation levels: 75%, 100...
