The word 'Agriculture' is derived from the Latin word 'Agri' means Land or field and 'Culture' means cultivation. It means the science and art of producing crops and livestock for economic purpose. The history of dates back to Indus Valley Civilization and even before that in some places of Southern India. India ranks second worldwide in farm outputs. As per 2018, agriculture employed 50% of the Indian workforce and contributed 17- 18% to the country's GDP. In todays world where transportation is perhaps one of the most utmost elements for the business to succeed, people are always in search of better, faster and cost-effective techniques of transporting, tracking and processing their goods. In recent years, the conveyor belt system has emerged as one of the best ways of transporting the product. This system consists of two or more drums that are also referred to as pulleys with a conveyor belt i.e. he carrying medium and it rotates around the drums. The belt is propelled by one or two of the pulleys. The pulley that powers the belt is called the drive pulley and the other is called the idler pulley. The conveyor belt is
categorized intotwo classes, one that transports general material and
the other that is responsible for taking agricultural material such as sand, ore, coal, salt, grain and much more from one place to another. Uses of conveyor in the agricultural community. The uses of a conveyor system agricultural community are numerous. It is used in the feeding process that processes or freezes vegetables, fruits, and other agricultural products for packing to be sent to the retailers or other process plants. Besides this, these belts are effectively being used for loading bulk quantities into trucks to get them transported to their final destination. Bean market is another place, where conveyor belt scales are used in a large number. Additionally, these belts are also to load out the soybeans into the trucks that carry them to the end process.
Saifallah Benjaafar al.  Discussed to minimize work- in-process. It shows that the choice of layout has a direct impact on work-in-process accumulation, manufacturing lead time, achievable throughput rates, and required material handling capacity. It has two methodology sources: the processing departments and the material handling transporter. In both cases, WIP accumulation is determined by
Variability in the arrival process.
Variability processing/ transportation time.
Utilization of the departments and the transporter.
The objective is to minimize work- in-process. the model to explore the relationship between layout configuration and operational performance. It showed that the conventional criterion of selecting layouts based on average material handling distances can be a poor indicator of queuing effect.

Deterministic-based, Probabilistic, Possibility. Approaches are stochastic programming, Robust programming, Simulation-based approach. it provides a structured overview of the recent use of operations research methodologies for handling uncertainties in the framework of agri-supply chain management. Operations research has a long tradition in improving quantitatively operations and supporting decision- making processes, able to manipulate with both deterministic and stochastic data.
Abhijit Gaikwad al.  developed the material handling equipment based on facilitate easy, cheap, fast and safe loading and unloading with least human interference. They approached design calculations and considerations of belt conveyor system for press machines, in terms of size, length, capacity and speed, roller diameter, power and tension, idler spacing, type of drive unit, diameter, location and arrangement of pulley, angle and axis of rotation, control mode, intended application, product to be handled as well as its maximum loading capacity in order ensure fast, continuous and efficient movement of material. the Conveyor Belt System for material handling improves the speed of material handling and the system reduces human effort. The workers are eliminated and ultimately the operation cost is reduced and profit gets increased.
Sheetal Roman al.  The conveyor is at a specific distance from floor level which runs at a very low speed so that it becomes convenient and flexible for the operator to assemble the vehicle parts while the conveyor is moving. Then the vehicle is manually unloaded at the last station. Conveyor Design Steps: Conveyor chain the following point should be considered. Chain design, Calculating Chain Pull Attachment, Coefficient of Friction, Service factor, attachments, finite element analysis, Testing, Inspection Funcion Testing, Load Testing. It argued that by integrating information technology with production processes many undesirable material handling activities could be easily avoided, also the companies would be able to attain increased space efficiency on the production/assembly area and decreased work in process.

Problem solving approach
A chain conveyor works on the principle of the interconnectivity of a chain connects each gear, resulting in a smooth carrying process. The chain conveyor has a series of gears connected into a continuous system by the chain. Typically, each gear has teeth that deliver a free rotational interface with the chain. A slat conveyor is a two-strand chain conveyor with slats connected to the chain and a guiding system for the slats. This creates a smooth surface to which tooling details or fixtures can be mounted to hold parts in the desired position. Slat Conveyors are used in horizontal conditions and operating at relatively slow speeds. They are generally used to move items that are not typically conveyable on rollers or belts, due to an irregular shape or bottom condition. So these approaches help to solve the problem of material handled in the agriculture field.
