aboveground to root biomass ratios in pea and vetch after treatment with organic fertilizer

چکیده
some growth parameters of pea (cv. pleven 4) and vetch (cv. obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the institute of forage crops, pleven, bulgaria. humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. ratios of aboveground weight to root system weight, aboveground height to root system length, as well as specific root length were determined. it was found that the growth variables of plants were positively influenced by organic fertilizer. the aboveground weight to root system weight ratios of pea ranged from 4.80 to 6.29 and was higher than vetch. aboveground height to root system length ratio in pea ranged from 6.95 to 7.93, and in vetch from 5.30 to 7.39. the use of organic fertilizer at the dose of 1.2 l/t and treatment during vegetation resulted in better performance of root system and specific root length was 78.6 for pea and 84.3 for vetch.

This research aimed to determine the effects of different cover crops and application ofbio-fertilizer on dynamic of nitrogen in the soil and sweet maize yield. Also, we evaluated theeffect of fall–winter species (common vetch, field pea, winter oats, fodder kale) and a mixtureof vetch and field pea with oats used as cover crops, as such as dead organic mulch andtraditional variant, without cov...

Bolinder, M. A., Angers, D. A., Bélanger, G., Michaud, R. et Laverdière, M. R. 2002. Root biomass and shoot to root ratios of perennial forage crops in eastern Canada. Can. J. Plant Sci. 82: 731–737. Shoot to root ratios (S:R) at peak standing crop are commonly used to estimate the annual crop residue C inputs to the soil from the root biomass left in the soil at harvest. However, root biomass ...
متن کاملAboveground biomass in Tibetan grasslands
This study investigated spatial patterns and environmental controls of aboveground biomass (AGB) in alpine grasslands on the Tibetan Plateau by integrating AGB data collected from 135 sites during 2001– 2004 and concurrent enhanced vegetation index derived from MODIS data sets. The AGB was estimated at 68.8 gm 2, with a larger value (90.8 gm 2) in alpine meadow than in alpine steppe (50.1 gm 2)...

Response of Inoculated Pea Plants (pisum Sativum L.) to Root and Foliar Fertilizer Application with Reduced Molybdenum Concentration
The effects of foliar absorbed nutrients on root processes related to assimilation of nitrogen under presence or absence of molybdenum (Mo) were studied. Pea plants (Pisum sativum L.), var. Avola were grown until the 15th day in a glasshouse on liquid nutrient solution both without and with Mo added to the media. Plants were inoculated with bacterial suspension of Rhizobuium leguminosarum bv. V...
