ABSTRACT The previous cultivation of green manures and mechanical soil decompression are options to minimize compaction the topsoil in no-tilage system (NTS) set different production systems Brazilian Savannah. In addition, it is essential relate these agricultural practices with economic benefits generated through cycles. objective this study was evaluate economically effect sporadic manure net gain margin upland rice "winter" common bean, under sprinkler irrigation, NTS lowland savannah....

Phosphorus (P) is a plant macronutrient that indispensable for maize (Zea mays L.) production. However, P difficult to manage in weathered soils, and its fertilization practice has low efficiency because it becomes unavailable absorption by roots. Symbiosis of plants with arbuscular mycorrhizal fungi increases growth enhances uptake from the soil not directly available Thus, objective this study was determine how inoculation Rhizophagus intraradices phosphate interacts influences development...

ABSTRACT In rice, the use of bacterium Azospirillum brasilense has shown to be very useful for crop, being able increase final productivity same or reduce need nitrogen in topdressing. It recently been noted that there are other regulators perform functions, such as thidiazuron (TDZ), a cytokinin-like substance significantly upland rice productivity. Thus, present work aimed verify effect interaction between foliar application A. and doses applied at occasion tillering plants on productive...

The adequacy of the best sowing times and choice rice cultivars is determinant for greater investment return in upland cultivation.Thus, this study identified time cultivar that expresses its yield potential, being adaptable stable, a low altitude Cerrado region.The was conducted during agricultural year 2016/17.The soil site typical clayey dystrophic Red Latosol.The experimental design randomized blocks, factorial scheme with four spring/summer season (October, November, December February),...

RESUMOA utilização de reguladores vegetais em arroz pode proporcionar redução na altura plantas e diminuir o acamamento. Objetivou-se verificar a influência da aplicação do regulador vegetal thidiazuron cultura terras altas, região Cerrado brasileiro. Utilizaram-se as cultivares BRS Esmeralda IAC 202, bem como delineamento experimental blocos casualizados, esquema fatorial 4 x 3 para cada cultivar, constituído doses (0 g ha-1; 0,3 0,6 0,9 ha-1) três épocas (perfilhamento, diferenciação...

O arroz é um cereal presente na alimentação básica diária brasileira, cuja demanda tem sido maior à medida do aumento populacional. Também uma cultura que, no regime de terras altas, ganhou espaço por possibilitar aproveitamento e recuperação áreas. Portanto, pode garantir rentabilidade ao produtor complementar a pelo grão mercado. Tendo em vista sistemas produção sustentáveis que impulsionam produtividade arroz, inoculação sementes com Azospirillum ser alternativa visto aumenta superfície...

ABSTRACT The symbiosis of common beans with nitrogen-fixing bacteria provides an efficient approach to sustainable and economical food production. Therefore, this study aimed evaluate the application cost-effective nitrogen management strategies in organic bean cultivation, including poultry manure liquid fertilizer, seed co-inoculation diazotrophic (Azospirillum brasilense and/or Rhizobium tropici), supplementary tropici inoculation. spanned three years a well-established cultivation field...

In modern agriculture, there is a challenge for adequately nourishing plants using sustainable techniques, mitigating the use of mineral fertilizers, especially nitrogenous which are most used corn crops.The objective this study to evaluate accumulation potential nitrogen, phosphorus and potassium in: a) cover crops (millet, crotalaria, pigeon pea, millet + pea fallow) b) sown in succession with application nitrogen doses (0, 40, 80 120 kg ha -1) topdressing inoculation via seeds...

The rationalization of water use, the increase in productivity and reduction nutrient losses are among current challenges agriculture.Recently, upland rice cultivar BRS Esmeralda with more tolerance to drought was released.Thus, objective this study evaluate hydric variation nitrogen sources topdressing Esmeralda.The experiment conducted at Education Research Farm UNESP located Selvíria, Mato Grosso do Sul (MS) state, 2013/14 2014/15.The field under randomized blocks a split-plot design...

Chemical seed treatment is an established practice in agriculture to protect crops from soil-borne pathogens and pests. Arbuscular mycorrhizal fungi (AMF) benefit plants by extending soil exploration as well water nutrient uptake.
