“…Additionally, the time, labor, and fuel required for mechanical weed control is a significant contributor to total production costs in organic cropping systems (Archer et al 2007). For example, compared with conventional production, time spent hand weeding was almost double in organic fresh market tomato ( Solanum lycopersicum L.) production (Hillger et al 2006), and on-farm fuel costs were almost double in organic soybean [ Glycine max (L.) Merr.] production (McBride and Greene 2009).…”

Strip-intercropping of functionally diverse cover crop mixtures including cereal rye (Secale cerealeL.) and hairy vetch (Vicia villosaRoth) is one mechanism by which nitrogen (N) banding can be applied to an organic, strip-tilled system to increase crop competitiveness over weeds. We hypothesized that by targeting hairy vetch, a low C:N legume, to the tilled strip directly in row with future crop establishment, and cereal rye, a high C:N grass, to the untilled strip directly between future crop rows, that N would be preferentially available to the crop. We conducted a field study between 2011 to 2013 in southwest Michigan to examine the effects of rye–vetch mixture spatial arrangement (strip intercropping vs. full-width mixture) on (1) soil inorganic N; (2) weed biomass; and (3) sweet corn (Zea maysL.) biomass, yield, and competitiveness against weeds. We found that as the proportion of vetch biomass in the crop row (in-row, IR) increased, we also saw increasing levels of IR soil inorganic N and greater early sweet corn N uptake and growth relative to weeds. However, sweet corn yield and final biomass were more responsive to vetch biomass across the whole plot (WP) and did not respond to rye and vetch segregation into strips. Increasing vetch WP biomass increased sweet corn final biomass across both years, but only increased corn competitiveness against weeds in 1 out of 2 years and decreased sweet corn competitiveness in the other year. Strip-intercropping of cereal rye and hairy vetch has potential to increase soil N availability to the crop, thereby increasing early crop competitiveness, which may lower weed management costs.

“…O Brasil destaca-se como um dos maiores produtores dessa cultura, considerando a produção destinada à indústria, com área colhida de aproximadamente 55.000 hectares e uma produção de cerca de 3.200.000 toneladas, atingindo a produtividade de 58.000 kg ha -1 em 2007 (AGRIANUAL, 2008). Entretanto, o tomateiro está sujeito à interferência negativa de plantas daninhas que competem por nutrientes, água e luz e podem causar sérios prejuízos à cultura, reduzindo assim sua produtividade (NASCENTE et al, 2004;HILLGER et al, 2006).…”

RESUMOO objetivo da presente pesquisa foi estudar o efeito da interferência de caruru-de-mancha (Amaranthus viridis), picão-preto (Bidens pilosa), tiririca (Cyperus rotundus) e Maria-pretinha (Solanum americanum) sobre a altura de plantas, a área foliar, o teor de clorofila, o acúmulo de massa seca e macronutrientes na cultura e a massa fresca de frutos do tomateiro industrial. Os tratamentos foram (a) duas plantas de tomateiro + duas de A. viridis; (b) duas plantas de tomateiro + duas de B. pilosa; (c) duas plantas de tomateiro + duas de C. rotundus; e (d) duas plantas de tomateiro + duas de S. americanum. Além disso, manteve-se uma testemunha com duas plantas de tomateiro sem associação com planta daninha. Dentro de cada espécie de planta daninha, o efeito sobre a cultura foi o mesmo para todas as características avaliadas, independentemente da distância utilizada. A. viridis e S. americanum foram plantas daninhas com maior capacidade competitiva que B. pilosa e C. rotundus. O teor de clorofila, a altura e a área foliar do tomateiro não foram afetados pela convivência com as plantas daninhas. B. pilosa e C. rotundus não influenciaram no acúmulo de macronutrientes do tomateiro, enquanto A. viridis e S. americanum afetaram de maneira diferenciada em função da distância utilizada, sendo A. viridis a espécie mais competitiva. A massa fresca de frutos do tomateiro não foi reduzida pela convivência com as quatro espécies de plantas daninhas.Palavras-chave: tomate, plantas daninhas, competição, crescimento, macronutrientes. ABSTRACT INTERFERENCE OF SLENDER AMARANTH, AMERICAN BLACK NIGHTSHADE, HAIRY BEGGARTICKS AND PURPLE NUTSEDGE ON PROCESSING TOMATOThe objective of the present research was to study the effect of interference of slender amaranth (Amaranthus viridis), American black nightshade (Bidens pilosa), purple nutsedge (Cyperus rotundus) and hairy beggarticks (Solanum americanum) on height, leaf area, chlorophyll content, dry mass and macronutrients accumulation and fruits fresh mass of processing tomato. The treatments were: (a) two tomato plants + two ones of A. viridis; (b) two tomato plants + two ones of B. pilosa; (c) two tomato plants + two ones of C. rotundus; e (d) two tomato plants + two ones of S. americanum. Moreover, a weed-free check with two tomato plants was maintained. For each weed species, the effect on tomato was the same for all evaluated characteristics, independently to distance used. A. viridis and S. americanum showed higher competitive potential than B. pilosa and C. rotundus. Chlorophyll content, plant height and leaf area of tomato was not affected by weed coexistence. B. pilosa and C. rotundus did not influenced on tomato macronutrients accumulation while A. viridis and S. americanum affected differentially it in function of distance used, and A. viridis was the most competitive species. Fresh mass of tomato fruits was not reduced due to coexistence with the four weed species.

“…and as a result reduce yield (Buckelew et al 2006;Garvey et al 2013). Herbicides, cultivation (in bareground tomato), hand weeding, mulch, and crop rotation are techniques used for weed management in tomato (Hillger et al 2006). It has been shown that crop rotation (with soybean, corn, or both) can improve yield and N fertilization (Seliga and Shattuck 1995) and have a positive effect in weed management (Bond and Grundy 2001).…”

Field experiments were conducted at the Ohio Agricultural Research and Development Center in Wooster, OH, in 2005, 2006, and 2007 to evaluate the tolerance of eight tomato varieties to thifensulfuron-methyl and POST control of broadleaf weeds. Herbicide treatments included thifensulfuron-methyl at 0, 6, and 12 g ai ha−1. In 2005, significant injury was observed in variety TR122244 at 1 and 3 wk after treatment (WAT). The highest crop injury in 2005 was 38% at 1 WAT for variety TR122244. However, this variety experienced a conflicting effect on crop marketable yield when treated with the low and high rates of thifensulfuron-methyl in 2005. Variety TR122244 had the highest crop injury, yet produced the highest marketable yield when treated with either rate of thifensulfuron-methyl. At 3 WAT in 2005, significant injury occurred in variety 11111120, with 13% injury recorded for both the high and low rates of thifensulfuron-methyl. No significant injury resulted from either rate of thifensulfuron-methyl at 1, 3, or 6 WAT in 2006 or 2007. However, in 2006 a significant marketable yield reduction was observed for variety 97045116 when treated with the high rate of thifensulfuron-methyl. No varieties experienced significant marketable yield effects or injury when treated with either rate of thifensulfuron-methyl in 2007. Registration of thifensulfuron-methyl herbicide is not recommended at this time because of the potential for crop stunting and yield reduction in certain tomato varieties.
