Introduction

Harvesting is the process of collecting the mature crop from the field.

Harvesting systems

1. Manual systemManual operation

sometimes using toolsLabor requirement:

48 person days / ha

1. Manual cutting Manual operation sometimes using toolsLabor requirement 48 person days / ha

Harvesting systems

Traditional Harvesting by using different Equipments like :Hand reaper •Rice, sugarcane,maize,jute etc harvest by Hand reaper

Manual system

Advantage & Problem of manual cutting

Advantage: •Local Equipment are not use power and fuel .•Unemployment problem reduce .

Problems :•More Labor Requirement•More Time & Cost consuming •Some time quality cannot ensure .

Harvesting systems

2. Machine cutting

Advantage & problem of machine cutting

• Advantages

– Saving time & Cost.– Crop loses minimum. – Quality production.

• Problems

– Places crop in window back in the field

– Problem with lodged crop– Complex cutter bar and

conveying mechanism

Commonly Use Machineries for crop Harvesting operation in Bangladesh

4. Combine harvestingCutting, hauling, threshing, cleaning in one combined operationLabor requirement: 1 OperatorCapital cost: > $ 250,000

Combine harvester

Combine harvester• Features

– capacity: 4-8 ha/day– combines cutting, threshing,

cleaning and hauling– tracks for mobility in wet

fields• Advantages

– high capacity– low total harvest losses

• Disadvantages– Requires relatively large field

sizes– Problem in terraced fields

Mini paddy cutter machine

Usage: Grain HarvesterType: Mini HarvesterDrive Type: Gear DrivePlace of Origin: BDModel Number: SAR-05Price: $150-200

Rice Reaper Binder Machine

•harvester price 1500$ -4500$ • harvester Performance 4G100 •Specifications 1.cutting width:1.0• 2.matched power:4.41kw (6.0hp) ...

When to harvest

• 20-25% grain moisture•80-85% straw colored and• the grains in the lower part of the panicle are in the hard doe stage • 30 days after flowering

Potato harvesterPotato harvesters are machines that harvest potatoes. They work by lifting the potatoes from the bed using a share. Soil and crop are transferred onto a series of webs where the loose soil is sieved out. Price :$200-700.

Mango Harvester •Traditional methods of harvesting (Mango,Guava,Papaya etc ).•Functions through the actions of holding, pulling and shearing600-800 fruits can be harvested per hour from a tree of about 4 m height in good bearing•Cost of device is Rs.250.

Losses during cutting

• Shattering loss = premature shedding of mature grains from the panicle caused by birds, wind, rats, and handling operations. Certain rice varieties shatter more easily than others.

• Lodging loss = plants with mature grains in the panicles fall on the ground making the grains difficult to recover.

• Standing crop loss = standing plants with mature grains are left standing in the field after harvesting operations as a result of oversight, carelessness or haste.

• Harvest at the right time and moisture content• Avoid stacking the cut crop in the field• Avoid delays in threshing after harvesting• Use the proper machine settings when using a

threshing machine

• Clean the grain properly after threshing • Avoid delay in drying after threshing
