Provedor de dados: 70
Autores: Gazola,Rodolfo de N.; Melo,Luiz M. M. de; Dinalli,Raíssa P.; Teixeira Filho,Marcelo C. M.; Garcia,Cássia M. de P.
The forage production in crop-livestock integration is critical both for formation of straw for no tillage planting and food for livestock farm. The experiment was conducted in the autumn/winter of 2009 and 2010, in the city of Selvíria -state of Mato Grosso do Sul -MS, Brazil, at Experimental Station of FEIS/UNESP. The objective was to evaluate the optimal depth for deposition of seeds of two Brachiaria species intercropped with corn with emphasis on grain yield and straw. The experimental design was a randomized block design in a factorial scheme 3 x 3, with four replications. The main treatments were two species of Brachiaria (Urochloa brizantha "Marandú" and Urochloa ruziziensis), which seeds were mixed with corn fertilizer and a control treatment...

GRANULOMETRY AND ENERGY CONSUMPTION AS INDICATORS OF DISINTEGRATION EFFICIENCY IN A HAMMER MILL ADAPTED TO EXTRACTING ARROWROOT STARCH (Maranta arundinacea) IN COMPARISON TO STARCH EXTRACTION FROM CASSAVA
Provedor de dados: 70
Autores: Branco,Fabiano P.; Naka,Marco H.; Cereda,Marney P.
ABSTRACT The commercial sector of starch extraction has fully automated plants with a minimum scale of 200 ton.day–1, which extracts starch from maize and cassava in Brazil. Although these starches are commodities, the market demands starches with special properties obtained without chemical modifications. A higher-priced starch can compensate for small-scale extraction, as in the case of arrowroot starch, which would correspond to an alternative income for the producer. As a small-scale equipment was not available in Brazil, it was necessary to adapt a hammer mill for arrowroot starch extraction, which should have a performance similar to that obtained from cassava roots using industrial grinders. The degree of disintegration and energy consumption were...

PARAMETERS OF OPERATIONAL PERFORMANCE OF SOIL PREPARATION AND SEMI-MECHANIZED TRANSPLANTATION OF COFFEE SEEDLING
Provedor de dados: 70
Autores: Cunha,João P. B.; Silva,Fabio M. da; Andrade,Ednilton T.; Barros,Murilo M. de.
ABSTRACT In recent years, the coffee has undergone major changes, and in case of transplanting operation, the use of machinery has proved to be a viable alternative to producers. Prior knowledge of the influence of the variables that influence the operational capability of these machines can generate models to estimate precisely these parameters, thus enabling the optimization and management of mechanized operations. One of this tool is the use of the response surface methodology, which allows checking the influence of different independent variables and the response generated to allow a great value. This study aims to verify the use of the response surface method to determine parameters of mechanized operations in coffee plant implantation. The results...

Harvest Cost and Value of Citrus Operations with Alternative Technology: Real Options Approach
Provedor de dados: 31
Autores: Iwai,   Nobuyuki; Emerson,   Robert D.; Roka,   Fritz M.
The prospect of immigration policy reform has renewed growers’ concerns of serious labor shortages and cost increases. These concerns are more serious for specialty crop agriculture, not only because it is highly labor intensive, but also it requires labor in a very short period, particularly at harvest time. Two representative approaches of the investment valuation have been applied to the case of harvesting mechanization for the model citrus grower in Florida. Specifically, we applied the NPV approach and the real options approach (ROA) to processed-market Hamlin orange operations in Southwest Florida.

The objectives of our project were the development of a model for estimating the working time requirement of all Austrian farms. A guideline was to calculate the working time requirement with the already ascertained data from INVEKOS and Statistics Austria. This resulted in the objectives to calculate the working time requirement on the basis of the area of the cultivated crops and the number of kept animals. The slope inclination can be additionally considered in mountainous regions. Further factors of influence had to be standardised. By taking all these guidelines into account a standard working time requirement was derived for the relevant farm activities starting with standard procedures and a standard mechanization. In the field of outdoor operations...

The structure of farms, farm households, and the rural communities in which they exist has evolved markedly over the last century. Historical data on a range of farm structure variables—including the value of agricultural production, commodity specialization, farming-dependent counties, and off-farm work—offer a perspective on the long-term forces that have helped shape the structure of agriculture and rural life over the past century. These forces include productivity growth, the increasing importance of national and global markets, and the rising influence of consumers on agricultural production. Within this long-term context of structural change, a review of some key developments in farm policy considers the extent to which farm policy design has or has...

Labor Cost and Value of Citrus Operations with Alternative Technology: Enterprise DCF Approach
Provedor de dados: 31
Autores: Iwai,   Nobuyuki; Emerson,   Robert D.; Roka,   Fritz M.
The prospect of immigration policy reform has renewed growers’ concerns of serious labor shortages and cost increases given that a large portion of the workforce is unauthorized for U.S. employment. This concern of labor shortages and cost increases is more serious for specialty crop agriculture which is highly labor intensive. Specialty crop growers may address the problem in various ways, but likely options include adoption of mechanical harvesting. In the current paper we study the citrus industry case and estimate the value for two operational modes (hand and mechanical harvesting) using the enterprise discounted cash flow (DCF) approach. Further we implement a simulation to forecast how the value for each operational mode would change with a change in...

Autores: Mome Filho,Edison Aparecido; Silva,Alvaro Pires da; Figueiredo,Getulio Coutinho; Gimenes,Fernando Henrique Setti; Vitti,André Cesar.
Modern agriculture techniques have a great impact on crops and soil quality, especially by the increased machinery traffic and weight. Several devices have been developed for determining soil properties in the field, aimed at managing compacted areas. Penetrometry is a widely used technique; however, there are several types of penetrometers, which have different action modes that can affect the soil resistance measurement. The objective of this study was to compare the functionality of two penetrometry methods (manual and automated mode) in the field identification of compacted, highly mechanized sugarcane areas, considering the influence of soil water volumetric content (θ) on soil penetration resistance (PR). Three sugarcane fields on a Rhodic Eutrudrox...

Autores: Cunha,João P. B.; Silva,Fabio M. da; Andrade,Ednilton T. de; Carvalho,Luis C. C.
ABSTRACT In super-mechanized coffee harvesting system, all operations are performed mechanically. In order to improve the logistics of mechanized agricultural operations, the knowledge on the variables that affect the operational performance can generate models to accurately estimate these parameters. The use of response surface methodology (RSM) allows to verify the influence of different independent variables and the generated response to allow for a great value. This study aimed to verify, using RSM, the influence of speed, mean length of rows and the slope of the areas on the operational performance parameters in different mechanized operations in coffee production, such as: harvest, sweeping and gathering. The results show that the slope directly...

Capacity of the mechanical harvesting process of sugar cane billets
Provedor de dados: 63
Autores: Peloia,Paulo Rodrigues; Milan,Marcos; Romanelli,Thiago Libório.
The mechanized harvest of sugar cane (Saccharum officinarum L.) in Brazil is an irreversible trend and it comes with a great concern about the quality of the cane delivered to the industry. A key component to quality is the billet length which affects the processing of raw material, cane deterioration, invisible losses and load density of transport vehicles. Thus, due to the importance of the billet standard in quality and cost of raw material, this study aimed to evaluate if the mechanized harvesting of sugar cane can supply the quality requirements for the crushing process, regarding the billet length. A plot with burnt sugar cane (3.2 ha) and another one with green sugar cane (8.0 ha) were selected to be harvested by two (2) self-propelled sugar cane...

Material flow determination through agricultural machinery management
Provedor de dados: 63
Autores: Romanelli,Thiago Libório; Milan,Marcos.
The approach of material embodiment in agricultural production systems is important because it determines the convergence of inputs (indirectly, the natural resources) to the field. Additionally, material flow is the basis for both environmental (energy analysis, emergy synthesis, life-cycle analysis and carbon inventories) and economical analyses. Since different materials cannot compose a single index, generally these flows are not shown, making comparisons among approaches difficult. Another aspect that makes comparisons difficult is the definition of the boundary of the studied system. If these boundaries differ, results will also be different, hiding actual distinctions among systems. The present study aims to suggest an arrangement of existing models...

Provedor de dados: 63
Autores: Costa Neto,Wilson Valente da; Elorza,Pilar Barreiro; Garrido-Izard,Miguel.
ABSTRACT: Since its inception approximately 50 years ago, the grape harvester has been one of the machines responsible for the expansion of viticulture in the world. In Spain, harvesters were introduced in the 1990s (there are now approximately 3,000 machines there as of 2017), while they were introduced in Brazil in 2010. Harvest mechanization requires specific crop adaption and new work features that deserve to be analysed from their very beginnings. The aim of this study was to evaluate the management of four commercial grape harvest machines under actual field conditions on an intercontinental basis in two locations in Brazil and Spain. Machine performance measured by work (ha h−1) and processing capacity (kg h−1), together with field efficiency (%)...

Provedor de dados: 111
Autores: Ishpekov, Stoyan Savov.
In this study we have experimentally determined the inertial force for releasing seeds from the capsules of six sesame genotypes that had been selected in IPGR- Sadovo, Bulgaria.The influence of seed moisture, the size and direction of the inertial force over the percentage of released seeds has been analyzed. The results of the study have proved that releasing the seeds is possible by inertial impacts, which do not require breaking up of the capsules of the tested sesame genotypes. Compared to the threshing, this impact can be applied to harvesting the seed with twice higher moisture, without mechanical damages and with lower energy consumption.
