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...

We sought to quantify changes in tree species composition, forest structure and aboveground forest biomass (AGB) over 76 years (1930-2006) in the deciduous Black Rock Forest in southeastern New York, USA. We used data from periodic forest inventories, published floras and a set of eight long-term plots, along with species-specific allometric equations to estimate AGB and carbon content. Between...

The growth of medicinal plants and biosynthesis of secondary metabolites is influenced by plant growth regulators. In this study we investigated influence offour levels (0, 500, 1000, and 1500 mg l-1) of2-chloroethyltrimethylammonium chloride (Cycocel), a plant growth retardant, on growth parameters and some biochemical parameters of cannabis plants. Cycocel only at 500 mg l-1 decreased shoot l...

the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

Sorghum (Sorghum bicolor ( L. ) Moench ) has emerged as a leading candidate for biomass utilization among energy crops due to high yield potential, ease o f culture and wide adaptibility. Previously, enormous diversity present in the germplasm has been manipulated by sorghum breeding programs primarily to produce grain, syrup or forage. Development of sorghums for energy utilization will requir...

Studied of genetic variability and its component traits path analysis were carried out among fifteen genotypes carrot (Daucus carota L). Highly significant differences between observed for all the characters. A moderate to wide range mean value different characters genotypes. Moderate high genotypic co-efficient variation, phenotypic variation with heritability, direct indirect effect on yield ...

Greenhouse experiments in a completely randomized design were carried out to investigate the effects of nitroxin fertilizer (0, 1 and 2 li/ha) on morphological and physiological traits of Amaranthus retroflexus in 2013. The traits in the study included plant height, fresh and dry weight of shoots, roots, stem and leaf, Chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, anthocyanin, a...
