“…Parker et al (1993) demonstrated that peach tree growth, expressed as change in trunk cross-sectional area (TCSA), was greater in a weed-free environment than a weedy environment. Other research documented that weed pressure in a young peach orchard reduced TCSA compared to a weed-free environment (Belding et al, 2004). Competition was also detected between apple trees and slow growing living mulches as compared to a weed-free control (Hoagland et al, 2008).…”

Trials were established at two locations to evaluate weed control provided by mulches and organic herbicides alone or in combination. Mulch treatments included barley straw, pine wood chips, paper, and no mulch (bare-ground control). Herbicide treatments included three organically certified herbicides: lemon grass oil (14% v/v), clove oil (8% v/v), and two rates of acetic acid (10 and 15% v/v). Other treatments included pelargonic acid (7% v/v), glyphosate (1.06 kg ai/ha), and no-herbicide (control). Individual herbicide treatments were applied according to weed pressure and were determined every 7 to 10 days. Herbicide applications were made two and three times in 2009 at Logan and Kaysville, respectively. Treatments were carried out for a second year at both locations with herbicide treatments applied a maximum of four times. A third trial was established in 2010 at Kaysville with four application times. Weed control evaluations were made once a month, and weed population densities were evaluated at the beginning and end of the season. Weed biomass and percent weed cover were collected at the end of the 2010 season. Mulches each provided significant weed suppression in the first year, but each mulch presented unique challenges over time. For example, paper mulch effectiveness decreased over time as cracks developed during wet-dry cycles allowing weed seedlings to emerge. Volunteer barley became problematic in straw mulch plots in the first year of each trial, and annual weed seed germination on top of the wood chip mulch became problematic in the second year. The straw mulch consistently provided among the highest weed control and the least end-of-season weed biomass. Glyphosate and pelargonic acid gave Use of trade names does not imply an endorsement of the products named or criticism of similar ones not named.Organic In-Row Orchard Weed Suppression 317 near 100% weed control among all mulch treatments, including the non-mulched plots. Lemon oil and clove oil displayed the same weed control ratings as the no-herbicide treatment in the three mulches (straw, wood chip, and paper), but displayed 41-95% weed control when applied without mulch. While organically certified herbicides generally did not provide sufficient weed control alone, some mulches and organic herbicide combinations provided weed suppression similar to conventional herbicide application.

“…However, any vegetation growing in plant rows and interrows of orchards is a strong competitor for water, nutrients, and yield (Wright et al, 2003;Belding et al, 2004). Previous studies have indicated that mowing the vegetation in the interrow and applying herbicides to the plant row are the best practices for sustainable soil management in orchards (Hogue and Neilsen, 1987;Lipecki and Berbeć, 1997).…”

Machinery-based farming operations used for perennial fruit crops often damage soils, particularly if the soil is wet and prone to compaction. We hypothesized that perennial vegetation growing in the interrows of orange orchards can mitigate the soil physical degradation from machinery traffic. The objective of this study was to investigate the effects of different groundcover management systems on the soil physical quality indicators including the least limiting water range (LLWR). An experiment was started in 1993 in a Typic Paleudult to evaluate three groundcover management systems: Bahia grass (Paspalum notatum) with mowing, perennial peanut (Arachis pintoi), and natural regrowth in which weeds were controlled by herbicide. The experimental design was randomized complete block with three replications. In May 2003, 216 undisturbed soil samples were collected at 0-0.15-m depths under and between wheel tracks in the orchard interrows. The soil bulk density, soil organic carbon content, resistance to penetration, soil water retention curve and soil resistance to penetration curve were determined in order to estimate the LLWR. The higher LLWR under wheel tracks in Bahia grass compared to perennial peanut or natural regrowth suggest that a better soil physical quality was achieved with Bahia grass. Key words: organic carbon, soil compaction, bulk density, resistance to penetration, available water Intervalo hídrico ótimo e qualidade física do solo em sistemas de manejo nas entrelinhas de citros RESUMO: Operações motomecanizadas utilizadas no manejo das entrelinhas dos pomares de frutas com freqüência causam a degradação física do solo, especialmente quando realizadas com o solo úmido e suscetível à compactação. A hipótese desse estudo é que a manutenção da vegetação permanente nas entrelinhas do pomar pode mitigar a degradação física do solo causada pelo tráfego de máquinas. O objetivo desse estudo é verificar o efeito de diferentes sistemas de manejo da cobertura permanente das entrelinhas sobre o intervalo hídrico ótimo (IHO) e a qualidade física do solo. Um experimento foi iniciado em 1993 num Argissolo Vermelho distrófico latossólico para avaliar diferentes sistemas de cobertura permanente do solo: gramínea "grama matogrosso" ou "grama batatais" (Paspalum notatum) com roçadas, amendoim forrageiro (Arachis pintoi) e vegetação espontânea manejada com herbicida. Em maio de 2003, foram coletadas 216 amostras de solo não deformadas na camada de 0-0,15 m de profundidade sob as posições de amostragem rodado e entrerrodado das máquinas nas entrelinhas do pomar. A densidade do solo, teor de carbono orgânico, resistência do solo à penetração, curva de retenção de água e curva de resistência do solo à penetração foram determinadas para estimar o IHO. A manutenção da cobertura do solo nas entrelinhas do pomar reduziu a compactação do solo e a utilização da gramínea proporcionou melhor qualidade física do solo no pomar de laranja. Palavras-chave: carbono orgânico, compactação do solo, densidade do solo, resistênc...

“…Cover crops can provide effective weed suppression for such cropping systems. Winter annual cover crops have been successfully incorporated into crop rotations and are most widely used to date to control weeds in various crops (Belding et al 2004;Brennan and Smith 2005;Buhler et al 1996;Hooker et al 1997).…”

Effects of alternative winter cover cropping systems on weed suppression in organically grown tomato (Solanum lycopersicum)

et al. 2009

Weed control is a major concern for organic farmers around the world and non-chemical weed control methods are now the subject of many investigations. Field studies were conducted in tomato (Solanum lycopersicum L.) from 2004 to 2006 at the Black Sea Agricultural Research Institute experiment field to determine the weed suppressive effects of winter cover crops. Treatments consisted of ryegrass (Lolium multiflorum L.), oat (Avena sativa L.), rye (Secale cereale L.), wheat (Triticum aestivum L.), gelemen clover (Trifolium meneghinianum Clem.), Egyptian clover (Trifolium alexandrinum L.), common vetch (Vicia sativa L.), hairy vetch (Vicia villosa Roth.) and a control with no cover crop. Treatments were arranged in a randomized complete block design with four replications. To determine the weed suppressive effects of the cover crops, weed density and total weed dry biomass were assessed at 14, 28, and 56 days after termination (DAT) of the cover crops from all plots using a 50×50 cm quadrat placed randomly in each plot. After cover crop kill and incorporation into soil, tomato seedlings variety 'H2274' were transplanted. Broadleaved weed species were the most prominent species in both years. Total weed biomass measured just prior to cover crop incorporation into the soil was significantly lower in S. cereale plots than in the others. The number of weed species was lowest at 14 DAT and later increased at 28 and 56 DAT, and subsequently remained constant during harvest. This research indicates that cover crops such as L. multiflorum, S. cereale, V. sativa and V. villosa could be used in integrated weed management programs to manage some weeds in the early growth stages of organic tomato.
