Abstract:
The Agricultural machinery rental services (UPJA) program has an important role on the application of agricultural mechanization and increasing farming income. This study aims: (1) to compare the farm costs between the farmers who apply mechanization under UPJA program and those who do not (Non-UPJA), and (2) to know the effect of implementing agricultural mechanization and the other factors toward farm income in Prambanan Sub-District, Sleman District. The data collected consists of 25 farmers who apply agricultural mechanization under UPJA program, choosen by sensus and 25 farmers who do not apply (Non-UPJA), choosen by using proporsional random sampling. To determine the differences of farm costs, farming analysis and mean difference test using independent sample t-test was applied. To determine the effect of mechanization toward farm income, multiple liniear regression analysis was used. The result of mean difference test showed that there is no significant differences of farm costs between UPJA and Non-UPJA farmers. The result of multiple liniear regression analysis showed that mechanization has significant effect to the farm income. Farm income of the farmers who apply mechanization under UPJA program is significantly higher than the farmers who do not. Other factors that have significant effect to farm income are land area, price of organic fertilizer and price of ZA fertilizer.

Abstract:
The paper attempts to explore the factors affecting the farm mechanization in Nepal, where agriculture is the primary livelihood of most people and the mechanization is crucial for efficient production and productivity. The government has also introduced a separate policy for agriculture mechanization in 2014. A primary data was collected from 300 households and analysed to assess and quantify the determinants of the farm mechanization. A descriptive analysis was carried out for understanding the data and the results were interpreted. Similarly, the multiple regression was executed to assess the factors affecting total investment in the farm machinery. The five different models were specified and compared for the better results. Moreover, to have deeper insight, the farm machinery was categorized into light machinery, heavy machinery and animal power. The results showed that light machinery is an essential part of Nepali farming system. Likewise, the presence of animal power, income per capita, per capita farm area, adaptation due to change in temperature, Household size, Farm area and income are significant determinants for total investment in farm mechanization.

Abstract:
This descriptive study was conducted to determine the coping strategies of farm laborers in San Jose, Occidental Mindoro towards farm mechanization. It was conducted at Barangay Central, San Jose, Occidental Mindoro, one of the top rice producing barangays in the province. The 123 of the 215 farm laborers listed in the different Kabesilya or farmers labor group were selected using simple random sampling. The farm laborers were engaged in planting and harvesting of rice for at least three years in Central, San Jose, Occidental Mindoro. The researcher used an interview schedule in gathering data. The study used descriptive statistics such as mean, frequency, and percentage. Pearson’s Product Moment Correlation was also used. Result shows that the farm laborers were in their middle aged, literate and with medium household size. The farm laborers generally “agree” that farm mechanization had affected their employment, food security level, education of children, monthly income, and agricultural production operations. The farm laborers “moderately practiced” the different coping strategies to meet the undesired effect of farm mechanization. Further, the “highly practiced” coping strategies were minimizing food expenses and seasonal migration of some household members to find odd jobs. Moreover, years spent in formal education and household size has a significant relationship on the extent of which farm laborers experience the effect of farm mechanization. Years spent in formal education have significant relationship on the coping strategies employed by farm laborers on advent of farm mechanization in the area.

Purpose The purpose of this paper is to investigate the impact of mechanization services on farm productivity in Northern China from an empirical perspective, with the aim to identify the underlying market and institutional barriers. Design/methodology/approach The authors apply the regression method with the control of village fixed effects to examining the relationship between capital–labor ratio, mechanization service ratio and farm productivity, using the panel data collected in 2013 and 2015 by CCAP. Findings Mechanization services improve farm productivity through substituting labor, but it may generate a less positive impact on farms who do not have self-owned capital equipment. Originality/value It is the first study to investigate how mechanization services affect farm productivity for grain producers in Northern China.

Abstract:
Identifying the determinants of farm mechanization can play a crucial role in the agriculture sector’s development. The present study identifies the determinants of potato farm mechanization employing the ordered probit model. A total of 150 potato farmers were interviewed to achieve the objectives. The findings indicate that only around 13% of the respondents were high adopters. The adoption of potato farm mechanization was influenced by education, spouse education, farm size, and training. Marginal effect analysis suggested that farm size and training decrease the likelihood of being in the low adopter’s category, respectively, by 13.2% and 10%, while increases the likelihood of being in the high adopter’s category by 7.5% and 5.7%. Policy implications included more investment in extension facilities such as training from public agencies to sustain and increase adoption. Modifying the existing extension strategy by targeting not only primary farmers but also members of their families would help with the widespread adoption of farm mechanization.

Abstract:
Effective utilization of farm machinery requires more than transfer of information. New skills have to be built among farmers, especially those introducing machinery for the first time. Building such skills requires infrastructure, trained personnel and time. The total capacity to train of the Farm Machinery Training and Testing Institutes of the Government of India at Budni, Hissar and Garladinne as well as the 20 agricultural universities in the country amounts to only about 7,000 a year compared to a need of about 25,000. Girja Sharan discusses how interinstitutional collaboration can help bridge the gap to enable farmers to realize the full benefits of mechanization.

A mamona tem demonstrado grande importância ao ser cultivada no período de safrinha, após cultivo de milho ou soja, e seu melhoramento visa à obtenção de materiais genéticos adaptados às condições de cerrado e com características apropriadas ao cultivo mecanizado. A implantação da cultura utilizando espaçamento reduzido entre plantas tem como finalidade adaptar a mamoneira às condições de cultivo similar ao da soja, para o aproveitamento do mesmo maquinário agrícola. Com isso, o objetivo deste trabalho foi avaliar o desempenho de híbridos de mamona no período de safrinha em espaçamento reduzido. Foram instalados dois experimentos no município de Primavera do Leste – MT, em 2011, ambos conduzidos em blocos ao acaso com quatro repetições. O primeiro experimento foi composto por 11 híbridos e uma cultivar testemunha IAC 2028, com espaçamento de 0,45m entre linhas e 0,35m entre plantas. O segundo, composto por sete híbridos e a mesma testemunha, com espaçamento de 0,45 m entre linhas e 0,50 m entre plantas. As características avaliadas foram produtividade de grãos (PG), porcentagem de plantas femininas (%), altura média das plantas (AP), altura de inserção do racemo primário (AI), diâmetro do colmo (DC) e número médio de racemos (NR). Para ambos os experimentos, os dados obtidos foram submetidos à análise de variância através do teste F e a comparação entre médias pelo teste de Duncan a 5% de probabilidade.No experimento 1, em relação a produtividade de grãos, verificou-se que os híbridos diferiram entre si, com maior produtividade observada no híbridos 4, com médias de 5.392,40 kg.ha-1. A testemunha (12) obteve uma produção menor que a média geral para esta característica.

Abstract: One of the main variables that affect the productive performance of operators of agricultural tractors and can cause serious health problems is the vibration generated during the operation of the machine. This work aimed to evaluate the vibration that affects the whole body of the operator through the seat of a farm tractor in a standardized vibration track test. It was used a 92 kW tractor with four conditions of ballasting: full weight, employing only solid ballast, only liquid ballast and completely without ballast, in four speeds of displacement: 1.19 m s-1; 1.47 m s-1; 1.75 m s-1 and 2.08 m s-1, and three combinations of inflation pressures in the rear and front axle, respectively: 82.73 kPa and 110.31 kPa; 110.31 kPa and 137,85 kPa and 137.85 kPa and 165.47 kPa. It was utilized a three-axis accelerometer (x, y, and z axes), fixed on the tractor seat for evaluation of the effect of vibration on the whole body of the operator. The acquisition was made with HVM-100 and software BLAZE ® 6.1.1, being obtained the average acceleration parameters, maximum and minimum acceleration, vibration dose value, the crest factor and the dose projection to 8 hours of work. It was realized the analysis of variance and average separation for all components analysed, and analysis of major components for the values of average acceleration and vibration dose value. All the statistical analyses were made with Tukey test at 5% probability (p < 0.05). Combinations of tire inflation pressures doesn't affected the values of vibration that occured on whole body of the operator. The speed was the factor that showed greater influence on vibration of the whole body of the operator, where the smallest tractor displacement speed resulted in the best scenarios. The maximum ballast presented the best scenarios for the operator when combined with the lower speed. For the vibration dose value was not found values above the ...

O Sistema Plantio Direto consiste no conjunto de técnicas que associam preservação dos recursos naturais, aliadas à mínima mobilização do solo. O desempenho da semeadora-adubadora está diretamente ligado aos mecanismos de contato com o solo, mais especificamente, as hastes sulcadoras. O objetivo deste trabalho foi avaliar a mobilização do solo, o desempenho operacional e o desenvolvimento da cultura do milho, quando semeado com dois tipos de hastes sulcadoras em três profundidades de semeadura. O experimento foi conduzido no ano agrícola de 2011/12 em área experimental da Fazenda de Ensino, Pesquisa e Extensão da UNESP/Jaboticabal em LATOSSOLO VERMELHO Eutroférrico típico. O delineamento experimental foi em blocos casualizados, esquema fatorial 2x3, com quatro repetições. As variáveis analisadas foram: área mobilizada, desempenho operacional e características agronômicas da cultura. A área mobilizada houve significância para os fatores haste e profundidade. O comportamento distinto das hastes é devido a seus parâmetros construtivos, sendo fator limitante para profundidade de trabalho, pois, determina o volume de solo mobilizado. No desempenho operacional do conjunto trator semeadora-adubadora houve diferença tanto para haste como profundidade. Desta forma opta-se pela haste que teve uma maior mobilização do solo e exigiu menor força e potência na barra de tração, trabalhando a menor profundidade desde que o solo esteja em condições adequadas de semeadura, um vez que não houve diferença na produtividade final de grãos
The no-tillage system is a set of techniques that combine natural resources preservation combined with minimum soil tillage. The seeder performance is directly linked to the mechanisms in contact with the soil, more specifically the planter shanks. This paper had as objective to evaluate the soil mobilization, operational performance and development of the corn crop when sown with two shank types furrow openers in three sowing depths. the operating performace of the tractor-seeder, soil tillage and agronomic characteristics of maize, working with two types of planter shanks fertilizer and three depths of operation. The experiment was conducted in the agricultural year 2011/12 at the experimental area the farm of teaching, research and extension UNESP/Jaboticabal on Eutrudox. The experimental design was completely randomized, 2x3 factorial with four replicates. The variables analyzed were mobilized area, operating performace and agronomic characteristics culture. The area mobilized indicated significant factors and depth shank. Results showed no interaction between types of shank and depth factors, however the mobilized area showed different behavior for shank factor because of this construction parameters, been a limiting factor for depth of work, thus determines the volume of mobilized soil. Operating performance of the tractor seeder was no difference for both shank as depth. Thus opts for shank had a greater mobilization of soil and required less force and power to the drawbar, working the shallowest depth where the ground conditions are suitable for sowing, one time there was no difference in the final yield of grains

Os sistemas de preparo do solo para implantação de culturas de grão são de grande importância, desde o desenvolvimento da cultura e desempenho de máquinas agrícolas até a conservação do solo e da água. Assim, para o produtor que deseja implantar culturas de grãos, faz-se necessário o conhecimento prévio do solo que se irá trabalhar, o tipo de ferramenta para prepará-lo, a máquina ideal para o aproveitamento de potência e a contribuição ao meio ambiente que o preparo de solo escolhido irá propiciar. Neste trabalho foram realizados três estudos que tiveram como objetivos avaliar a emissão de CO2 do solo, o desempenho de máquinas agrícolas e o desenvolvimento da cultura do milho em função da quantidade de solo mobilizado por hastes sulcadoras em sistema plantio direto e hastes subsoladoras em sistemas de preparo localizado do solo. No primeiro estudo foram utilizadas três hastes sulcadoras (H1: inclinada com ângulo de ataque de 17°; H2: reta, com ponteira inclinada e ângulo de ataque de 29° e H3: parabólica e ângulo de ataque de 27°) e cinco profundidades de trabalho (5,5; 9,0; 12,5; 16,0 e 19,5 cm). No segundo estudo utilizou-se a haste H1 em três profundidades de trabalho (9,0; 12,5 e 16,5 cm) e quatro teores de água do solo (TAS 1, 2, 3 e 4), estando o solo mais seco no TAS1 e mais úmido no TAS4. Ambos estes estudos em Latossolo Vermelho eutroférrico e sistema plantio direto com mais de 8 anos localizados na região de Jaboticabal-SP-Brasil. Para o terceiro estudo utilizou-se uma haste subsoladora em três profundidades de preparo localizado do solo, conhecido também como preparo em faixas (strip-tillage) nas profundidades de 26, 32 e 38 cm, em solo franco-arenoso Dothan, localizado no norte da Flórida (Estados Unidos da América).

The soil tillage systems for grain crops deploying are of great importance, since crop development and performance of agricultural machinery to the soil and water conservation. Therefore, for the producer who want to cultivate grain crops, he needs before to get knowledge about soil, the tool type to prepare it, the ideal machine for the power utilization and the contribution to the environment that soil tillage system chosen will provide. This study carried out three experiments that the aim was to evaluate the soil CO2 emission, the performance of agricultural machines and the corn crop development as a function of the disturbed soil amount by furrow opener hoe type in no-tillage system and subsoiler opener in strip-tillage system. In the first study we used three planter furrow opener hoe type (H1: inclined at 17° rake angle; H2: straight, with inclined tip and 29° rake angle and H3: parabolic and 27° rake angle) and five working depths (5.5, 9.0, 12.5, 16.0 and 19.5 cm). In the second study we used the H1 opener in three working depths (9.0, 12.5 and 16.5 cm) and four water content of the soil (WCS 1, 2, 3 and 4), it being dryer in WCS1 and wetter in WCS4. Both of these studies was carried out in eutroferric Red Latosol and no-tillage system with more than 8 years (Jaboticabal city, São Paulo, Brazil). In the third study we used a subsoiler opener at three working depths (26.0, 32.0 and 38.0 cm) in strip-tillage system, in a Dothan sandy loam (north Florida, USA). For the first study, the geometry of the opener directly affected soil disturbance, machine performance and the crop development. However, we suggested that the inclined opener with 17° rake angle, working at greater depths, because this combination presented lower fuel consumption per volume of disturbed soil without reducing crop yields. For the second study, the opener disturbed more soil at greater depths, but this increase was not proportional from the ...

Abstract:
India, the world’s largest producer of cotton, contains more than 4 million cotton farms that are less than 5 acres. These farms are incapable of large-scale mechanization due to small farm size and irregular farm shape. A previous team developed a handheld, roller-based picking device that demonstrated increased performance over similar products. However, a significant improvement in productivity requires increasing picking speed through mechanization as well as increasing worker cotton carrying capacity. We present a system that utilizes the roller-based picking device in tandem with a compressive storage bag and an efficient carrier. Through modeling and initial testing, the system demonstrates a two times (2X) improvement in worker productivity over current methods. This paper characterizes the cotton picking process, details the modules of the integrated system, and suggests further procedural improvements for greater increases in worker productivity.

Abstract:
In recent years, there has been an increasing demand for tractor usage for agricultural activities in the world. Tractors are an integral part of mechanization and have a crucial role to play to enhance agricultural productivity. They are used for many kinds of farm work, under various soil and field conditions. It provides agricultural activities in challenging conditions by using several farming equipment. During the operations, tractors have to efficiently transfer power from the engine to the drive wheels and PTO through a transmission. Tractor clutch is the essential element in this system. During the torque transmission, loads which occur on the clutch components cause damages. In many cases, especially PTO clutch finger mechanism is fractured under the torque transmission. In this study, finger mechanism, which used in tractor clutch PTO disc, is investigated. Finite element analyses were performed for two different thicknesses (3.5 and 4 mm) of the finger mechanism. Stress and deformation values which occur during the transfer of power in a safe manner are investigated for these thicknesses. The finger mechanism CAD models were created using CATIA V5 and then imported into ANSYS for static finite element analyses. As a result of the analyses, approximately 13% stress decreasing was observed with the increment of the 0.5 mm for the finger thicknesses. Results from the analyses provide an accurate prediction of the material yielding and load path distribution on the PTO clutch finger. To verify the analyses results prototype PTO finger mechanism was manufactured and was conducted bench tests. Consequently, a good correlation was achieved between finite element model and test results.
