DESIGN AND DEVELOPMENT OF A TRACTOR OPERATED CARROT HARVESTER AND TRIMMER

Carrot (Doucus carota) is a very popular and one of the most important vegetable being cultivated and consumed in Pakistan; it ranks key position amongst winter vegetables. Carrots are cultivated on an area of 13.9 thousand hectares, with the production of 242.3 thousand tonnes (FAO, 2007, 2008). The national normal yield for carrot is just 17.5 tons ha-1, which is very low when contrasted with other propelled nations like Belgium (47.64 tons ha-1), Denmark (44.29 tons ha-1), and the United Kingdom (44.28 tons ha-1).

The harvesting of carrot is important stage in the cultivation technology because maturity period of carrot is about 100-120 days so carrot crop needs harvesting within a narrow time span. Generally, the farmers use traditional tools and methods for trimming of leaf and digging of carrot.  In manual harvesting the labor has to stoop forward while digging/pulling carrot from the bed/ridge and also during picking up. Stooping posture results in a lot of bio-mechanical stresses in the back and has higher energy consumption as compared to other working positions. On an average about 250-300 man-hrs/ha are required for trimming, digging and pulling of carrot. Due to industrialization, availability of labor and high labor charges has made the manual harvesting uneconomical. This is one reason that is why 13.36% and 14.5% decrease in area under carrot cultivation and carrot production respectively, has been observed during last one year.

 

OBJECTIVES;

The purpose of the project to enhance carrot productivity through introduction, promotion and provision of economical & efficient farm mechanization. Benefits

  • Timely operations will ensure quality and quantity of the material increasing yield and profitability

  • Precision farming methods and associated machinery and equipment

  • It will reduce 60-70 % labor requirement

  • Less than 2 % crop damage

  • With machine operation ultimately cost of harvesting will be reduce to 30-40 percent with better harvesting efficiency compared to manual harvesting.
