Weed pressure in 1995 was incredible! What happened to produce such a glorious crop of weeds? The answer: drought! The Drought of 1995 and Weeds and Weed Control in 1996 Weed pressure in 1995 was, in a word, incredible! I toured many areas — golf courses, lawns, athletic fields, and institutional grounds — that were solid crabgrass, knotweed, clover, etc. In many of these areas, if there weren’...

Assessment of seasonal variation in concentration of heavy metals–As, Cd, Co, Cr, Cu, Ni, Pb, and Zn from the Siloam Geothermal Spring and their impacts on surface soils and Mangifera indica were undertaken during winter and summer seasons in South Africa. This was done to determine the environmental pollution status of surface soils and Mangifera indica around the geothermal spring. The geothe...

—Spring-migration ecology of staging Northern Pintails, Anas acuta, was investigated in south-central Nebraska, USA. Habitat associations, local movements, settling patterns, arrival dates, residency times and survival were estimated from 71 radiomarked pintails during spring 2001, 2003 and 2004, and diet determined from 130 females collected during spring 1998 and 1999. Seventy-two percent of ...

Effects of water deficits on leaf turgor maintenance processes were analyzed for pear trees (Pyrus communis L. cv. "Barlett") grown in 120-liter containers. Four irrigation treatments were applied: a well-watered control treatment, a spring water stress cycle (Sp), a summer water stress cycle (Su), and a spring plus summer water stress cycle (Sp + Su). For the Sp treatment, water application wa...

AIM To compare the efficacy of photon-induced photoacoustic streaming (PIPS) technique with conventional, sonic and ultrasonic irrigation on the removal of apically placed dentinal debris from an artificial groove created in a root canal. METHODOLOGY Root canal preparation was performed up to size 40 on 48 extracted single-rooted teeth using ProTaper rotary instruments. The specimens were the...

In this study, a detailed hydrochemical evaluation has been made to determine the chemical processes of spring waters and their suitability for irrigation. The study area consists drainage basin Gökpınar dam fertile soils irrigable agriculture. During period August 2017 October 2018, regular samples were collected monthly from 10 140 in total subjected analysis. For purpose, 11 parameters such ...

Considering profitability in pasture-based systems, investigating parameters affecting crop coefficients for irrigation management becomes important. In this experiment, we determined the coefficient of ‘Marandu’ palisadegrass based on accumulated degree-days and estimated plant water consumption under single (‘Marandu’ alisadegrass) mixed + black oats Italian ryegrass) cropping regimes. The re...
