ABSTRACT- The increasing population and the pastures inability to meet food needs in livestock have led to the increase of cultivates forage plants. In order to evaluate the effect of plant growth promoting rhizobacteria (PGPR) and alfalfa (Medicago sativa) extract on the growth and concentration of macronutrient and micronutrient contents of  forage sorghum (Sorghum vulgare), an experiment was...

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 t...

Sweet cherries (Prunus avium L.) contain various phenolic compounds which contribute to total antioxidant activity. Total polyphenols, tannins, flavonoids and anthocyanins, and antioxidant capacity in a fruits of a number of selected sweet cherry genotypes were investigated. Total polyphenols content ranged from 4.12 to 8.34 mg gallic acid equivantents/g dry fruit weight and total tannins conte...

Abstract Trials were conducted in two experimental runs at the Purdue University Horticulture Greenhouses, West Lafayette, IN, to determine ‘Redefined Murray Mitcham’ peppermint tolerance tiafenacil. Established 20-cm-diameter polyethylene pots was subjected a simulated harvest by removing aboveground biomass substrate surface; then, tiafenacil applied 0, 25, 50, 100, and 200 g ai ha −1 . Visib...

introduction: increasing crop competitive ability is an important part of integrated weed management (iwm). in this regard, identifying weeds reaction to soil fertility status for developing fertilizing methods, as components of iwm programs, is a necessity. materials and methods: in order to evaluate the growth characteristics of purple nutsedge under the conditions of interference with onion,...

Accidental, runaway veld fires cause enormous fodder flow problems in dry regions. It was the objective of this study to estimate the short-term (one year) impact of fire over 10 growing seasons (1995/96 – 2004/05) on the productivity (aboveground phytomass and litter) of a semi-arid grassland ecosystem. Fire caused a 41% decrease in basal cover over the first season following burning. On avera...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...

Estimates of national-scale forest carbon (C) stocks and fluxes are typically based on allometric regression equations developed using dimensional analysis techniques. However, the literature is inconsistent and incomplete with respect to large-scale forest C estimation. We compiled all available diameter-based allometric regression equations for estimating total aboveground and component bioma...

—Total aboveground live tree biomass in Puerto Rican lower montane wet, subtropical wet, subtropical moist and subtropical dry forests was estimated using data from two forest inventories and published regression equations. Multiple potentially-applicable published biomass models existed for some forested life zones, and their estimates tended to diverge with increasing tree diameter at breast ...
