Pathology challenges Turf nematodes are worm-like animals that are less than one-eighth of an inch long. Because they can't be seen by eye or hand lens, live hidden in the soil and cause no specific symptoms in turfgrasses, nematode damage goes unnoticed or is explained away to other problems, such as poor fertility, soil compaction, watering or diseases. The first symptom of nematode damage is...

Jerusalem artichoke is a staple for the raw material base of healthy food, beverages, feed, medicine, and fuel, in addition to being source its herbage tubers. The choice conditions cultivating variety depends on purpose or direction crop products obtained from it. This research involved laboratory on-farm studies 16 varieties different maturity groups cultivated sod-podzolic sandy loam soils d...

Drought is one of the major threats to cowpea productivity in tropical countries, and understanding its impacts germane ensuring food security a global context. The present study was established screen some accessions for drought tolerance at flowering stage pots under controlled conditions house. High significant differences were observed among wilting recovery traits, stomatal conductance, re...

To ensure the selection of wheat genotypes that are resilient to future climatic conditions, with drought already being most significant and acute problem in many areas, twenty winter cultivars were tested for stress tolerance from beginning stem elongation (DC 30; Zadoks decimal codes) 49 days (until stage grain development, DC 73–75) within an automatic phenotyping platform. The control plant...

Abstract Due to global shifts in climate, studies contrasting conditions of two natural and climatic zones are particular interest: (1) subzone mixed broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, therefore increase loss quality materials. The frequency occurrence mycoses autumn is 2-14 tim...

Pastures cover, in Brazil, around 165 million ha, most of them are at some degradation level. Recovering these pastures is essential. The objective this study was to evaluate the sensibility soil organic matter (SOM) and its physical attributes pasture different levels (1 4), Capoeiras 2) secondary Forest (Control). Samples were collected four depths (0.00-0.05, 0.05-0.10, 0.10-0.20 0.20-0.40 m...

[1] Tower-based measurements of mass and energy exchanges at the end of the growing season in central Botswana were used to evaluate functional relationships commonly applied to predict water and carbon fluxes between savanna landscapes and the atmosphere. Following a large rainfall event, daily evapotranspiration (ETdaily) exhibited an exponential decay consistent with a derived analytical exp...

We present a novel measurement setup for monitoring changes in leaf water status using nondestructive terahertz time-domain spectroscopy (THz-TDS). Previous studies on a variety of plants showed the principal applicability of THz-TDS. In such setups, decreasing leaf water content directly correlates with increasing THz transmission. Our new system allows for continuous, nondestructive monitorin...

Nitrogen nutrition exerted a strong effect on stomatal sensitivity to water stress in cotton. In well-watered plants grown with 0.31 millimolar N in the nutrient solution, stomata closed at a water potential of -9 bars even though the wilting point was below -15 bars. For each doubling of nutrient N level, the water potential for stomatal closure decreased by about 2 bars. Elevated intercellula...
