They all emphasize an important factor in the operation of a farm or ranch in today‟s world Management is important This does not mean that management was not important in the past However in agriculture which is highly mechanized, uses many technological innovations, and operates with large amounts of borrowed capital, management takes on a new dimension and importance Why some farmers make more money than others? Why some farm businesses grow and expand while others struggle to maintain their current size? Good or bad luck can not explain all the differences observed in the profitability of farms and ranches even among those which have about the same amount of land and capital available Farm business records from many states show the top one-third of the farm to be highly profitable while the bottom one-third are often operating as a loss Why the difference? Observation and analysis often lead to the same conclusion The difference is due to management These differences in management can show up in three areas: production, marketing and financing Production differences include the choice of agricultural commodities to be produced and how they are produced Marketing includes the when, where, and how of purchasing inputs and selling commodities Differences here are reflected in different prices paid and received Financing covers not only borrowing money and the related questions of when, where, and how much, but also the entire area of how to acquire the resources necessary to produce agricultural commodities There is risk to be considered in all three areas – how farm managers adapt to and handle this risk can have a major impact on profit If management is so important, we must ask even more questions What exactly is management? What managers ? what is the difference between management and labor ? what knowledge and skills are needed to become a better manager ? Farm and ranch management There are some differences in the management of a farms or ranch and a management of a non-farm business corporation The obvious differences are in size, type of business, and the products or services produced Other differences include the relationship between labor and management and the setting of goals In a corporation, the board of directors sets policies and goals and hires managers to achieve them It is generally easy to separate corporation employees who are managers from those who provide the labor necessary to produce a product or provide a service On a typical farm or ranch, one individual or a family group sets the goals, provides the management, and performs much or all of the labor required This makes it difficult to separate the management activity from labor because the same individuals are involved and both tasks may be performed at the same time For example, a farmer may be mentally planning a marketing strategy or developing next year‟s cropping program while operating a tractor or combine When one person performs both the management and labor functions, there is a danger that the immediate need for labor to perform some task will place management in a secondary role, with management decisions postpones or delayed These differences are not readily apparent when definitions of business management and farm and ranch management are compared, but they are nevertheless important There are many different textbook definitions of farm and ranch management, but several common English for Specific Purposes 77 78 points run through all of them One of the more concise definitions is „Farm management is concerned with the decisions which affect the profitability of the farm business‟ This broad definition contains several important points First, it identifies profitability as a major objective of the business but not necessarily to the exclusion of other objectives Second, this definition specifically identifies decisions and decision making as part of the management process Other farm management texts contain alternative definitions but with many of the same concepts or ideas There is usually some reference to decisions or decision making as being part of management process Also some mention is made of goals or objectives This may be done in general terms, or a more specific goal such as profit maximization may be identified as being an important end to which the management effort is directed Finally, some mention of the organization and operation of the farm or ranch business is included in many definitions Farm and ranch management can be thought of, then, as being a decision-making process It is a continual process because of the continual changes taking place in our economy and in an individual business The decision are concerned with allocating the limited resources of land, labor, and capital among alternative and usually competing uses This allocation process forces the manager to identify goals and objectives to guide and direct the decision making In this text, the following definition will be adopted: farm and ranch management is the decision-making process whereby limited resources are allocated to a number of production alternatives to organize and operate the business in such a way as to attain some objective(s) While this definition is somewhat long, it does identify most of the characteristics of the management activities found on farms and ranches II Comprehension questions: Why has farm management taken on a new dimension and importance ? Does luck account for the success or failure of farms ? What factor does account for the success or failure of farms ? In what three areas does the farm manager face risks ? What is different between a farm and a business corporation ? Why is it difficult to separate management and labor on a farm ? What danger does a farmer who is both manager and worker face ? What ideas most definitions of farm management have in common ? How does the writer think of farm management ? 10 Why does this process go on all the time ? III Vocabulary: Look at the first paragraph again What words respond to the definitions: a measurement of any sort something new that is introduced physical strength money with which the business is started or expanded English for Specific Purposes 78 79 something that is said Look at par again What words have the same meaning as: keep present, at the moment working Look at par 3, again What words have the opposite meaning to: minor exclude selling lending ignorance Look at par 5, again What words have the same meaning as: carries out, does reach, attain employs in the mind very clear, easy to understand put off until the later date Look at par 10 What words correspond to these definitions ; giving as a share or for a purpose choice between two or more things by which IV Grammar: A Eg: –ing form or the infinitive ?

Where the model tests take place ? How many sails has the windmill got ? What shape are they ? What is the purpose of the experimental studies ? The advantage of the V-axis sailing water pumping system in comparison to the Savonius-type - o0o - MECHANIZATION IN SUGAR CANE PRODUCTION - DEVELOPMENT OF SEED CANE PLANTER Sugar cane is one of the sweet source producing crop grown in tropical and subtropical regions Sugar cane is grown as one of the main crops in south-east islands of Kagoshima and Okinawa which locate the most southern part of Japan, and contributed to the development of regional agricultural industries Recently, the number of farmers decreased in sugar cane production region and the cultivated area or the yield of sugar cane tends to decrease For sugar cane production, many kinds of operations are required such as tilling, planting, weed control, applying pesticide, harvesting, leaf stripping and conditioning The mechanization of each operation has been demanded and tilling, maintenance of the field and harvesting operation have been mechanized, and the working hour has gradually decreased while the growing area per farm household has increased in these several years But the seed-cane planting has not mechanized which shares nearly 20% of the whole working hours for sugar English for Specific Purposes 83 84 cane production Therefore, to develop the full automatic seed-cane planter, a prototype machine was developed and the planting performance was evaluated Seed-cane planting The first step for planting sugar cane is to prepare the seed-cane which is cut from the stem in the length of 20 to 30 cm generally containing two buds After tilling and making groove on field, seed-canes are put horizontally at the bottom of the groove and covered with soil at the depth of around 20 to 30 cm Some parts of the seed-cane planting operation is mechanized as the one or two additional operator should ride on a planting machine which is called semi-automatic planter The aiming of this research is to develop a full automatic seed-cane planter with any additional operator This system enables to operate all of the planting procedure such as tilling soil, seed-cane planting, covering soil and mulching by one operator who is driving a tractor This research may contribute to the establishment of the mechanized sugar cane production from planting through harvesting In this research, a feeding mechanism of two buds-seedcane was developed and evaluated With the results obtained in a laboratory test, field tests were carried out mounting the developed system behind tractor and rotary tiller Materials and methods The seed-cane variety used in this test was Nco310 and the 20 cm seed-cane were cut from the sugar cane stem of 150 to 180 cm length The average diameter of the seed-canes was 2.1 cm and weight was 77.3 g The schematic diagram of the tested seed-cane feeding mechanism is shown in the Fig below The seed-canes are kept in hopper which can hold 500 seed-canes and are shaken by the board for the smooth feeding to the rotating roll The seedcane are fed downward by a couple of rolls (20cm diameter and 30cm length) to the groove conveyor and then carried to the planting outlet At the lower end of the shaking board, 12 links of chains are attached to assist the smooth feeding of seed-canes The board was shaken by a cam attached on roll shaft and they shook times per one rotation of the roll The roll was made of urethane rubber A guide plate was mounted under the roll to ensure seed-canes filling in conveyor groove The under cover of the conveyor was supported by coil spring The outlet height was designed to be 30cm from the bottom regarding the conventional planting method A VS motor was used for driving the roll and the conveyor at laboratory experiment (adapted from the reports at the International Workshop of Agricultural Mechanization Current Situation and Issues of Priorities, 1998) Question: Where is sugar cane grown ?
