Resumo: | Industrial tomato production is hampered by weed occurrence, which may reduce productivity through competition, affect the efficiency of products applied to crops and host commercially important diseases and pathogens. Thus, this study aimed to evaluate the occurrence and management of weeds in industrial tomato cropping systems in the Cerrado of Goi?s. In Chapter One, the viable seed bank was evaluated in areas with different weed management systems. The evaluation was made in two conventional tillage areas (CT); two with no-till (NT) and four with no-till and reduced soil preparation (RSP). The most frequent weeds were Conyza bonariensis, Cenchrus echinatus, Ipomoea aristolochiaefolia, Leonotis nepetifolia, Spermacoce latif?lia, Senna obtusifolia, Nicandra physaloides, Euphorbia heterophylla, Gnaphalium spp., Brachiaria plantaginea, Zea mays, Bidens pilosa, Macroptilium spp., , Solanum lycopersicum (tiguera), Commelina benghalensis and Sida rhombifolia. Among the soil preparation systems, reduced preparation (RSP) resulted in two species with higher germination: Phyllanthus tenellus and Oxaliss pp. Conventional tillage (CT) resulted in six species with the highest plant emergence number ? Ageratum conyzoides, Coronopus didymus, Portulaca oleracea, Eragrostis pilosa, Digitaria horizontalis and Solanum americanum. In Chapter Two, different systems of weed management in tomato crops for industrial processing under center-pivot irrigation were evaluated. The applied treatments were combinations between harrowing and chemical management with glyphosate, s-metolachlor, sulfentrazone and metribuzin-based products at different application periods. The variables plant population and ?Brix were not influenced by the treatments. There was statistical difference within the production components: twenty-fruit mass, yield per plant and productivity. Highest productivity was observed in the following treatments: a) harrowing thirty days after transplant (DAT), application of glyphosate (1,080 g ha-1), metribuzin (480 g ha-1) and s-metolaclhor (1,200 g ha-1) on the seventh DAT (83.39 t ha-1); harrowing on the 30th DAT, glyphosate (1,080 g ha-1) and s-metolachlor (1,200 g ha-1) on the seventh DAT (74.75 t ha-1); c) harrowing on the thirtieth DAT, glyphosate (1,080 g ha-1) on the 14th DAT and sulfentrazone (100 g ha-1) on the seventh DAT (73.06 t ha-1); d) harrowing on the 30th DAT, glyphosate (1,080 g ha-1) on the 14th DAT and s-metolachlor (1,200 g ha-1) on the seventh DAT (71.83 t ha-1) and; e) harrowing on the 30 DAT, glyphosate (1,080 g ha-1) and sulfentrazone (100g ha-1) on the seventh DAT (71.75 t ha.-1).With the ?no weeding? and ?harrowing-only? treatments, there was reduction of 63.82% and 69.29% in fruit productivity, respectively, compared to the weeded sample. The conclusion is that the applications of sulfentrazone (100 g ha-1) or s-metolachlor (1,200 g ha-1) in weed management systems using glyphosate revealed potential alternatives for industrial tomato production in Goi?s. |

Com isso, este trabalho teve como objetivos avaliar a ocorr?ncia e o manejo de plantas daninhas em sistemas de cultivo de tomateiro industrial no Cerrado goiano. No primeiro cap?tulo, avaliou-se o banco de sementes vi?veis de ?reas com diferentes sistemas de manejo de plantas daninhas. As avalia??es foram feitas em duas ?reas de plantio convencional (PC), duas de plantio direto (PD) e quatro de plantio direto modificado com preparo reduzido do solo (PPR). As esp?cies de plantas daninhas mais frequentes foram Conyza bonariensis, Cenchrus echinatus, Ipomoea aristolochiaefolia, Leonotis nepetifolia, Spermacoce latif?lia, Senna obtusifolia, Nicandra physaloides, Euphorbia heterophylla, Gnaphalium spp., Brachiaria plantaginea, Zea mays, Bidens pilosa, Macroptilium spp., Solanum lycopersicum(tiguera), Commelina benghalensis, Sida rhombifolia. Entre os sistemas de preparo do solo, o preparo reduzido (PPR) apresentou duas esp?cies entre as de maior germina??o, a esp?cie Phyllanthus tenellus e a Oxalis spp. O plantio convencional (PC) apresentou tr?s esp?cies com maior n?meros de plantas emergidas, sendo Eleusine indica, Digitaria horizontalis e Amaranthus hybridus. O plantio direto (PD) teve seis esp?cies com maior emerg?ncia em compara??o aos outros manejos de solo, sendo Ageratum conyzoides, Coronopus didymus, Portulaca oleracea, Eragrostis pilosa, Digitaria horizontalis e a Solanum americanum. No segundo cap?tulo, objetivou-se avaliar diferentes sistemas de manejo de plantas daninhas na cultura do tomateiro para processamento industrial em parte de lavoura comercial sob piv? central. Os tratamentos utilizados foram combina??es entre o uso da gradagem e manejo qu?mico com produtos ? base de glyphosate, s-metolachlor, sulfentrazone e metribuzin em diferentes ?pocas de aplica??o. As vari?veis popula??o de plantas e ?Brix n?o foram influenciadas pelos tratamentos. Houve diferen?as estat?sticas para os componentes de produ??o: massa de vinte frutos, produ??o por planta e produtividade. As maiores produtividades foram observadas nos seguintes tratamentos: a) gradagem aos trinta dias antes do transplantio (DAT), aplica??o de glyphosate (1.080 g ha-1), metribuzin (480 g ha-1) e de s-metolaclhor (1.200 g ha-1) aos sete DAT (83,39 t ha-1); b) gradagem aos 30 DAT, glyphosate (1.080 g ha-1) e s-metolachlor (1.200 g ha-1) aos sete DAT (74,75 t ha-1);c) gradagem aos trinta DAT, glyphosate (1.080 g ha-1) aos 14 DAT e sulfentrazone (100 g ha-1) aos sete DAT (73,06 t ha-1); d) gradagem aos 30 DAT, glyphosate (1.080 g ha-1) aos 14 DAT e s-metolachlor (1.200 g ha-1) aos sete DAT (71,83 t ha-1) e ; e) gradagem aos 30 DAT, glyphosate (1.080 g ha-1) e sulfentrazone (100 g ha-1) aos sete DAT (71,75 t ha.-1). Nos tratamentos ?sem capina? e ?apenas gradagem?, houve redu??o de 63,82% e 69,29% na produtividade de frutos, respectivamente, em rela??o ? testemunha capinada. Conclui-se que as aplica??es de sulfentrazone (100 g ha-1) ou s-metolachlor (1.200 g ha-1), em sistemas de manejo de plantas daninhas contendo glyphosate, se revelaram alternativas potenciais na cultura do tomateiro industrial em Goi?s.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2018-01-26T16:05:57Z No. of bitstreams: 1 2014 - Sebasti?o Nunes da Rosa Filho.pdf: 2091591 bytes, checksum: f35a1bfbdc5bdd66764178c67ffba67b (MD5)Made available in DSpace on 2018-01-26T16:05:57Z (GMT).

Industrial tomato production is hampered by weed occurrence, which may reduce productivity through competition, affect the efficiency of products applied to crops and host commercially important diseases and pathogens. Thus, this study aimed to evaluate the occurrence and management of weeds in industrial tomato cropping systems in the Cerrado of Goi?s. In Chapter One, the viable seed bank was evaluated in areas with different weed management systems. The evaluation was made in two conventional tillage areas (CT); two with no-till (NT) and four with no-till and reduced soil preparation (RSP). The most frequent weeds were Conyza bonariensis, Cenchrus echinatus, Ipomoea aristolochiaefolia, Leonotis nepetifolia, Spermacoce latif?lia, Senna obtusifolia, Nicandra physaloides, Euphorbia heterophylla, Gnaphalium spp., Brachiaria plantaginea, Zea mays, Bidens pilosa, Macroptilium spp., , Solanum lycopersicum (tiguera), Commelina benghalensis and Sida rhombifolia. Among the soil preparation systems, reduced preparation (RSP) resulted in two species with higher germination: Phyllanthus tenellus and Oxaliss pp. Conventional tillage (CT) resulted in six species with the highest plant emergence number ? Ageratum conyzoides, Coronopus didymus, Portulaca oleracea, Eragrostis pilosa, Digitaria horizontalis and Solanum americanum. In Chapter Two, different systems of weed management in tomato crops for industrial processing under center-pivot irrigation were evaluated. The applied treatments were combinations between harrowing and chemical management with glyphosate, s-metolachlor, sulfentrazone and metribuzin-based products at different application periods. The variables plant population and ?Brix were not influenced by the treatments. There was statistical difference within the production components: twenty-fruit mass, yield per plant and productivity. Highest productivity was observed in the following treatments: a) harrowing thirty days after transplant (DAT), application of glyphosate (1,080 g ha-1), metribuzin (480 g ha-1) and s-metolaclhor (1,200 g ha-1) on the seventh DAT (83.39 t ha-1); harrowing on the 30th DAT, glyphosate (1,080 g ha-1) and s-metolachlor (1,200 g ha-1) on the seventh DAT (74.75 t ha-1); c) harrowing on the thirtieth DAT, glyphosate (1,080 g ha-1) on the 14th DAT and sulfentrazone (100 g ha-1) on the seventh DAT (73.06 t ha-1); d) harrowing on the 30th DAT, glyphosate (1,080 g ha-1) on the 14th DAT and s-metolachlor (1,200 g ha-1) on the seventh DAT (71.83 t ha-1) and; e) harrowing on the 30 DAT, glyphosate (1,080 g ha-1) and sulfentrazone (100g ha-1) on the seventh DAT (71.75 t ha.-1).With the ?no weeding? and ?harrowing-only? treatments, there was reduction of 63.82% and 69.29% in fruit productivity, respectively, compared to the weeded sample. The conclusion is that the applications of sulfentrazone (100 g ha-1) or s-metolachlor (1,200 g ha-1) in weed management systems using glyphosate revealed potential alternatives for industrial tomato production in Goi?s. |
