A comparação dos efeitos da aplicação reguladores de crescimento cloreto mepiquat e chlormequat isolados combinados no algodoeiro (Gossypium hirsutum L.) cv. CNPA ITA 90 constituiu o objetivo do presente trabalho. O experimento foi conduzido ano agrícola 1998/99 Município Primavera Leste, MT. Foram estudados 15 tratamentos com quatro repetições, utilizando-se delineamento experimental blocos casualizados. altura das plantas a parcelada 24% menor em relação à testemunha, independentemente...
O objetivo deste trabalho foi comparar diferentes métodos de estimação da adaptabilidade e estabilidade produtiva em 17 genótipos algodoeiro avaliados 23 ambientes do Cerrado brasileiro. Os efeitos a interação x foram significativos. modelos ecovalência AMMI indicaram cultivar BRS Cedro como mais estável, enquanto as cultivares Delta Penta Ipê identificadas instáveis; nenhuma delas esteve entre produtivas. De acordo com o método Eberhart & Russell, Lin Binns Annicchiarico, 269 - Buriti...
O objetivo deste trabalho foi avaliar a produção, persistência da matéria seca e eficiência dessecação em espécies vegetais utilizadas para cultivos de cobertura do solo, quantificar seus efeitos sobre produtividade algodoeiro plantio direto. realizado Santa Helena Goiás, GO, com 16 tratamentos: Panicum maximum, cultivares Mombaça, Tanzânia Massai; Urochloa brizantha, Piatã, Xaraés, Marandu MG4; U. decumbens; Paspalum atratum cv.

Abstract The aim of this study was to investigate soil C and N stocks physical properties under a cotton ( Gossypium hirsutum ) based system using no‐till (NT) conventional tillage (CT). experiment established as randomized block design with four replications six treatments follows: [NT1], NT crop rotation cotton/soybean Glycine max )/maize Zea mays + brachiaria Brachiaria ruziziensis ); [NT2], soybean/maize brachiaria/cotton; [NT3], maize brachiaria/cotton/soybean; [CR1], CT annual...
Sustainable production systems, such as the no-tillage system (NTS), have a tendency to increase organic carbon in soil. However, Brazilian cotton production, conventional tillage (CTS) is predominant, and long-term studies on crop under NTS are scarce. The present study aimed evaluate effect of soil management rotation systems fiber yield well nitrogen accumulation This was conducted savanna over 9 years consisted following four treatments with different systems: CTS succession or crops...
Com o objetivo de avaliar os efeitos diferentes doses cloreto mepiquat aplicadas parceladamente no algodoeiro (Gossypium hirsutum L.) cv. CNPA-ITA 90, dois experimentos foram conduzidos durante anos agrícolas 1993/94 e 1994/95, na Fazenda Itamarati, Ponta Porã, MS. As estudadas foram: 1) 0,0; 2) 12,5+12,5+25,0 (50,0); 3) 25,0+25,0+25,0 (75,0); 4) 0,0+ 50,0+50,0 (100,0) 5) 12,5+62,5+50,0 (125,0) g ha-1 mepiquat. O delineamento experimental utilizado foi blocos casualizados, com quatro...
Cotton cultivar BRS 336 is a high-quality fiber upland and has wide adaptation to the Brazilian growing areas, with resistance bacterial blight. exhibited length higher than 32.0 mm in all field tests. Also, strength exceeded cotton currently grown Brazil.
BRS 369RF and 370RF were developed by the EMBRAPA as a part of efforts to create high-yielding germplasm with combinations transgenic traits. are midseason cultivars have yield stability, adaptation central Brazilian savanna, good fiber quality tolerance glyphosate herbicide.
Com o objetivo de avaliar efeito doses cloreto mepiquat aplicadas forma parcelada, foi conduzido, em Jaboticabal, SP, um experimento com a cultivar algodoeiro IAC 22. O delineamento experimental blocos casualizados, 13 tratamentos e 4 repetições. do sobre redução da altura das plantas mais evidenciado pela dose total aplicada que pelo uso esquema parcelamento. A menor estudada (55 g/ha) suficiente para as plantas, por ocasião colheita, estivessem inferior 1,30 m. proporcionou no comprimento...
Cotton cultivar BRS 293 is a midseason high-yield and has wide adaptation to the Brazilian savanna, yield stability, desirable resistance main cotton diseases good fiber quality. The meets growers' demands for competitive lint as well fulfilling industrial textile requirements.
Abstract: The objective of this work was to evaluate the dry matter yield cover crops and their suppressive effects on weeds. experiment carried out during three years in a cerrado area state Goiás, Brazil, consisted 16 treatments with fallow cultivated single cropping intercropping. Fallow allowed high weed infestation. Cover affected composition weeds, which showed greater diversity fallow, followed by Pennisetum glaucum 'BRS 1501' Cajanus cajan crops. In average experimental years,...
Este trabalho objetivou avaliar a produção, persistência e os efeitos de coberturas vegetais sobre as plantas daninhas produtividade do algodoeiro em sistema plantio direto.

Moench), capim-pé-de-galinha (Eleusine coracana Gaerth), Crotalaria juncea L., spectabilis Roth, aveia-preta (Avena strigosa Schreb.), nabo...
BRS 372 and 416 are cotton cultivars with high lint yield genetic resistance to the main diseases in Brazil, particularly Ramularia Leaf Spot. They have stable yields, good fiber quality can contribute a sustainable disease management tropical environments.
Adequate potassium (K) fertilization is essential for agricultural production in soils of the Brazilian Savanna (Cerrado biome) due to high demand by crops (especially cotton), likelihood leaching losses, and dependence on fertilizer importations. Therefore, sustainability requires improvements soil efficiency management. This study evaluated influence management crop succession or rotation combinations with cotton K dynamics exchangeable reserves profile, partial balance after nine years...
Cotton cultivar BRS 335 is a midseason high-yield and has adaptation to the Northeast Brazilian savanna, yield stability, desirable resistance main cotton diseases good fiber quality. The meets growers' demands for competitive lint as well fulfilling industrial textile requirements.
Mepiquat chloride (MC) is widely used for controlling cotton plant growth. Shoot growth modifications may affect root and, consequently, interfere with the sensitivity to water deficit. This study aimed at evaluating deficit effects, in initial phenological stages of plants from seeds treated MC doses, on shoot and Two experiments were carried out a greenhouse, Santa Helena de Goiás, Goiás State, Brazil, randomized blocks design, 4x4 factorial scheme: four regulator doses (0 g, 2 4 g 8...

Fiber length exceeds 32.5 mm strength 33 gf tex-1.
Cotton cultivar BRS 368RF was developed by EMBRAPA in a partnership with the Bahia Foundation, aiming to create high-yielding germplasm adding transgenic traits addressed Brazilian Savanna (cerrado) of Northeast and North regions. is midseason has yield stability tolerance glyphosate.
O sistema de produção predominante na cultura do algodoeiro é o convencional manejo solo, que tem proporcionado degradação dos atributos físicos, químicos e biológicos solo. Com objetivo avaliar efeito Sistema Plantio Direto (SPD) Convencional Manejo Solo (SC) sobre a produtividade fibra das cultivares BRS Cedro, Jatobá Araçá, foram conduzidos experimentos em Primavera Leste, MT, no período 2006/2007 2012/2013. foi cultivado SPD, obedecendo à seguinte sequência para os períodos verão...
Among the species cultivated in Mato Grosso do Sul, area with soybeans is larger than that only for pasture cultivation. This work was developed fourteen municipalities of state. Based on information from Brazilian Institute Geography and Statistics (IBGE), evolution occupied by soybean, sugarcane these analysed. In particular, has shown constant significant growth. On other hand, been continuously decreasing, especially Ponta Porã, Maracaju Rio Brilhante. The areas previously pastures are...
