Biochar soil amendment can improve growing medium water and nutrient status crop productivity. A pot experiment was conducted using Solanum lycopersicum var. cerasiforme plants to investigate the effects of biochar (20% application rate) on a soilless substrate, as well plant growth, fruit yield, quality. During experiment, substrate characteristics, morphological traits, root leaf C/N content ...

ABSTRACT Neotyphodium coenophialum, an endophytic fungus associated with tall fescue grass, enhances host fitness and imparts pest resistance. This symbiotum is implicated in the reduction of stresses, including plant-parasitic nematodes. To substantiate this implication, toxicological effects of root extracts, polyphenolic fraction, ergot, and loline alkaloids from endophyte-infected tall fesc...

a factorial pot experiment based on randomized complete blocks design with fourreplications was carried out in order to evaluate salt tolerance of four sugar beet cultivarsincluding madison (british origin) and three iranian cultivars (7233-p12, 7233-p21 and7233-p29) using carbon isotope discrimination (δ). plants were grown in sand culturemedium in greenhouse conditions. sugar beet cultivars w...

In order to investigate the relationship between hydraulic lift and drought tolerance in potato, four cultivars differing susceptibilities were selected, a pot experiment with three different irrigation conditions was carried out randomized complete block design. Under (WW), of soil water not observed upper pots. half-irrigation (DW) (DD) conditions, content increased pots, along change root-re...

When soil moisture is heterogeneous, sap flow from, and ABA status of, different parts of the root system impact on leaf xylem ABA concentration ([X-ABA]leaf). The robustness of a model for predicting [X-ABA]leaf was assessed. 'Two root-one shoot' grafted sunflower (Helianthus annuus L.) plants received either deficit irrigation (DI, each root system received the same irrigation volumes) or par...

A pot experiment was conducted at Faculty of Education, Alzaiem Alazhari University, Sudan, during 2019/2020 to evaluate the effect Amaranthus viridis powder on emergence and growth Swiss chard (Beta vulgaris var. cicla). The set as a completely randomized design (CRD) with four replicates. In treatments incorporated into soil rate (0, 0.5, 1.0. 1.5 2.0% w/w) representing T1 (control), T2, T3, ...

An experiment was conducted to examine the influence of soil aggregate size on maize root growth and development. The loamy samples resulted from different number passes rotary tilling experimental runs under controlled bin were selected. texture chosen in this study sandy loam. obtained after interval 10 (10, 20, 30, 40, 50, 60 passes) at moisture content 10.28 % (w.b). Soil collected kept for...

The use of microalgae as natural biofertilizer in horticulture has recently been reported, while the humic substances is widespread. However, combined with applied to plant leaves still unexploited. Thus, objective this work was combine fulvic acid (FA) Scenedesmus subspicatus microalga biomass (SC) a via leaf two onion cultivars organic system. Four experiments were conducted: i) bioassays ver...
