Em virtude das altas taxas de decomposição do material orgânico em regiões tropicais, um dos problemas para a manutenção e sustentabilidade do sistema de plantio direto é a necessidade de produção de grandes quantidades de palha. Com o objetivo de identificar, no sistema de integração agricultura-pecuária, as variações dos atributos físicos do solo e a produtividade de grãos de soja sobre palhada de braquiárias, este trabalho foi conduzido na FEPE-UNESP de Ilha Solteira, SP, e o delineamento experimental utilizado foi o de blocos ao acaso, com nove tratamentos em esquema fatorial (3 x 3), com quatro repetições. Os tratamentos foram constituídos por três espécies de braquiárias e três modalidades de consórcio das braquiárias com o milho. Os atributos...

Em regiões de clima tropical, com altas taxas de decomposição do material orgânico, uma alternativa para suprir o aporte anual de palha exigido para proporcionar a sustentabilidade do sistema plantio direto é a consorciação de forrageiras com culturas produtoras de grãos. Com o objetivo de identificar, no sistema de integração agricultura-pecuária, a melhor modalidade de consorciação de três espécies de braquiária (Brachiaria brizantha B. decumbens, e B. ruzizienses) com milho outonal (linha, entrelinha e entrelinha na época de adubação de cobertura do milho), foi conduzido o presente trabalho. Foi utilizado o delineamento em blocos ao acaso, no esquema fatorial (3x3), com quatro repetições. Foram avaliadas: massa seca de palha do milho, massa seca da...

ABSTRACT Several authors have been questioned the desiccation interval between the coverage plants and sowing plants for the soybean crop. Therefore, this study aimed to evaluate the desiccation time of the spring sorghum as a predecessor crop for summer soybean and then for autumn bean, focusing on the straw formation for maintenance of the no-tillage system and to evaluate the yield of soybeans and beans grain, as well as analyzing the interference of sorghum straw in these cultures. The experiment was developed in the Teaching and Research Farm of FE/UNESP located in Ilha Solteira/SP where it was used an experimental design of randomized blocks with five treatments and six repetitions. The treatments consisted of five different intervals between sorghum...

The sustainability of no-tillage system is fully linked to the soil use and management, in order to use technologies that promote the accumulation of dry vegetation in the soil, but it may affect the performance of agricultural machinery. Therefore, the objective of this study was to evaluate in soybean seeding the operational performance of tractor-seeder on maize straws intercropped with Urochloas in different treatments. The study was conducted in a randomized block design in factorial scheme 2 x 4 + 1, with four replications, formed by two intercropped forage species and five cropping systems. The dry maize straw, Urochloas dry mass and total straw dry mass were determined in treatments to verify the operational performance of the machines. The results...

ABSTRACT The no-tillage system optimizes agricultural areas, maintaining the supply of straw and promoting crop rotation and soil conservation. The aim of the present study was to evaluate sowing quality and grain yield of corn intercropped with three forage species of the Urochloa genus associated with two corn population densities. The experiment was conducted at the São Paulo State University (UNESP), in Jaboticabal-SP, Brazil. The experimental design was randomized blocks in a 2 x 3 factorial scheme with four replicates. The treatments consisted of two corn densities (55,000 and 75,000 plants ha-1) intercropped with three forages (Urochloa brizantha, Urochloa decumbens and Urochloa ruziziensis) sown between rows of corn in the V4 stage. The following...

The use of no tillage system associated with the crop-livestock integration is an alternate managing that promotes the accumulation of dry matter in the soil, an essential fact to make the system sustainable and profitable. The aim of this study was to evaluate the operational performance of a planter-tractor set on maize straws intercropped with Urochloa, in different seeding modes. The soybean crop was seed on the intercropping of two forage species (Urochloa brizantha and Urochloa ruziziensis) in five cropping systems: MBL (Maize with Urochloa in the maize seeding row, mixed with base fertilizer and deposited at 0.10 m), MBE (Maize with Urochloa seeded between rows at the same day of seeding maize), MBC (Urochloa between rows of maize seeded with the...

ABSTRACT The sowing process is one of the most important steps in agricultural production chain, requiring a good efficiency in order to avoid seed and plant population losses. In order to achieve a satisfactory performance of the seeder, the agricultural implement needs to be properly adjusted. Therefore, the present study aimed to verify both the operational performance and sowing quality of the agricultural equipment, depending on different working depths and different operating velocities. The experimental design was a factorial, with two theoretical velocities and three working depths. The velocity of 6.8 km h-1 achieved both a good operating consumption and a low fuel consumption per working area and when associated with working depth of 0.05 m...

ABSTRACT Agribusiness daily increases the demand for machinery with better efficiency, seeking to reduce operating costs and improve the quality of the sowing process. The objective of present study was to evaluate the quality of the longitudinal seed distribution and the operating performance of a seeder-fertilizer according to displacement velocity and furrowing mechanism for fertilizer deposition. The assay was conducted in the experimental area of the Department of Agricultural Engineering of the Federal University of Ceará. The experimental design was randomized blocks, in a 2 x 3 factorial, with four replicates with two furrowing mechanisms for fertilizer deposition (double disc and shank) and three displacement velocities (4.7, 6.3 and 8.2 km h-1)....
