Corn (Zea mays L.) is one of the main commodities of Brazilian agribusiness, however, the sowing operation of this crop still presents challenges related to the performance of the metering mechanisms and operational speed, since these can affect the physical quality of the seeds and impair germination. The aim of this study was to evaluate the physical quality of maize seeds as a function of different metering mechanisms and operational speeds in a controlled sowing trial. The experiment was carried out at the State University, UNESP/Botucatu-SP, using five commercial models of seed dosers at four operational sowing speeds. The results showed that the metering model and the operational speed directly affected the physical quality of the corn seeds,...

A cultura do milho, quando sujeita a instabilidades climáticas, pode sofrer reduções severas no rendimento de grãos. O entendimento e a quantificação dos riscos climáticos envolvidos na produção de milho é, portanto, o primeiro passo para que se estabeleçam estratégias de manejo que possam minimizar esses riscos. Objetivou-se com este trabalho avaliar a variabilidade interanual da produtividade e a diferença entre a produtividade potencial e atingível de milho de sequeiro, para diferentes datas de semeadura, na safra e safrinha, em Rio Verde, Goiás. Empregou-se o modelo CSM-CERES-Maize, previamente parametrizado, juntamente com 33 anos de dados históricos diários de clima para simular cenários de épocas de semeadura, na safra e safrinha, e para avaliar a...

A preliminary study of the behaviour and vitality of reseeded juvenile great scallops, of three sizes in three seasons
Provedor de dados: 5
Autores: Fleury, Pierre-gildas; Mingant, Christian; Castillo, A.
In order to have a better understanding of recessing in great scallop, Pecten maximus and consequently the causes of mortality at reseeding, this study has monitored, at different seasons, the dispersion and recessing of different sizes of juveniles (about 15, 30 and 45 mm, called small, medium and large) after seeding. Moreover, the aim was to see when small spat (15 mm) could be seeded, and thus reduce the costs of intermediate culture. Three monitoring approaches were used together: (1) continual observations by remote video camera, of a defined area (less than 1 m2) containing 10 scallops from each size group; (2) daily monitoring of behaviour with divers along three bottom lines, with 20 × 1 m2 plots each and nine marked scallops per plot; and (3) the...

Provedor de dados: 91
Autores: Santos,Viviane C. dos; Santos,Paulo R. A. dos; Lima,Isabela O.; Pereira,Valberto R. F.; Gonçalves,Flávio R. F.; Chioderoli,Carlos A.
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)....

Provedor de dados: 91
Autores: Feitosa,Jardênia R.; Fernandes,Haroldo C.; Cecon,Paulo R.; Leite,Daniel M.; Nery,Filipe M. T.; Pereira,Janielle S.
ABSTRACT Excessive tillage operations under inadequate conditions can raise the cost of agricultural production and lead to soil degradation without adequate crop response. The objective of this study was to evaluate the onion crop response to soil water contents and tillage systems. Three tillage systems were evaluated: P1 (plowing + two harrowings + two seedbed raising operations), P2 (two harrowings + one seedbed raising operation), P3 (one harrowing + one seedbed raising operation); and four soil water contents: 12, 15, 23 and 26%. The experiment was conducted in the irrigated perimeter of Tourão, Juazeiro, BA, Brazil (9° 24’ 7.3” S; 40° 26’ 8.7” W and altitude of 368 m), in 2017, and was installed in split plots, in a randomized block design, with...

Seed distribution by punch seeder in family farming
Provedor de dados: 124
Autores: Melo,Rafaela Paula; Albiero,Daniel; Praciano,Aline Castro; Monteiro,Leonardo de Almeida; Garcia,Angel Pontin.
ABSTRACT Family farming seeks to use less-aggressive agricultural practices, however, there is little machinery available that is suitable for the reality of this sector. This has led to the use of technically incorrect practices, which have contributed to the impoverishment, compaction and desertification of agricultural soils. Punch seeders are seen as a promising alternative for carrying out sowing in family farming, as they employ localised seed distribution with less disturbance of the soil and the consequent preservation and conservation of its structure. The aim of this study was to evaluate the quality of seed distribution by a punch seeder used in family farming. The experiment was carried out in a soil classified as a Red-Yellow Argisol....
