the present study was carried out in order to test the effect of grapevine rootstocks root growth on biomass and leaf nutrition status in extreme soil conditions. own rooted cuttings of rootstocks fercal, teleki kober 5bb, georgikon 28 and four new rootstock hybrids from the breeding program of georgikon faculty, hungary (fb01, jb01, zamor 17 and szf10) were grown 3 months in pots. the 5 l pots...

papermill sludge (pms) is the waste product from the paper manufacturing industry and is produced in considerable quantities worldwide. this investigation characterised a pms from a papermill plant in south africa and investigated the potential for direct land application of the pms to soil. in a pot experiment, application of pms to three contrasting soils at equivalent rates of 0, 10, 20 and ...

Large pot (2 years) and field experiments (1 year) were conducted to determine the response of susceptible soybean Glycine max (L.) Merr. cultivars (Essex and Hutcheson) grown in soybean-cyst-nematode (SCN), Heterodera glycines-infested soils at three soil water regimes. The soil water regimes were irrigation whenever soil water potential ([psi]s) 0.30-m deep was i) -30 kPa (I-30) or ii) - 50 k...

A pot experiment and afield trial were conducted to study the remediation of an aged field soil contaminated with cadmium, copper and polychlorinated biphenyls (PCBs) (7.67 +/- 0.51 mg kg(-1) Cd, 369 +/- 1 mg kg(-1) Cu in pot experiment; 8.46 +/- 0.31 mg kg(-1) Cd, 468 +/- 7 mg kg(-1) Cu, 323 +/- 12 microg kg(-1) PCBs for field experiment) under different cropping patterns. In the pot experimen...

since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, plantago ovata forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in jiroft, kerman province, south of iran. as the firstfactor, drought stress included four le...

The physico-chemical characteristics as well as chemical composition of Arachis hypogaea shell (AHS) ash were evaluated by different techniques such as X-Ray fluorescence, X-Ray diffraction and thermo-gravimetry. The material, which is considered a by-product obtained from Groundnut shelling, was investigated as a potential fertilizer, energy source and as animal feeds. And this will provide a ...

The interaction of retention time in the rumen and concentrate diet on methane production in vitro and acetate:propionate ratio was examined. Twenty-four fistulated sheep were used in a complete factorial design with the sheep randomly divided into 4 groups. The sheep had a 5-wk acclimatization period on an oaten chaff diet, followed by two 3-wk diet phases. Two of the 4 groups were maintained ...

This paper presents the mesh selectivity of a net pot for white-spotted conger eel Conger myriaster. A cover-net fishing experiment was carried out in October 1995 and 1996, using five mesh openings; 11.6, 13.6, 15.5, 18.1, and 21.0 mm with a cover-net of 10.8 mm mesh opening. Each mesh-size net pot had a slightly different mesh selectivity curve in terms of R(=G/P), girth ratio G to mesh perim...

In this study, it is aimed to determine the effects of comboutea and lyophilized culture on soil some biological features. This study was carried out 2 different soils as a pot experiment in greenhouse. 4 doses (0, 10, 20, 30 ml/pot) 0.25, 0.50, 0.75 mg/pot) were applied with kg apiece pot. At end experiment, basal respiration (BR) microbial biomass carbon (MBC) analyzes made taken from pots. A...
