What is pre-harvest handling?

INTRODUCTION. A pre-harvest system may be defined as a system of existing technologies for agricultural raw materials production. Thus, the term describes the fundamental technical and economic relations within agriculture.

What are the three pre-harvest factors?

The pre-harvest factors influencing postharvest quality were cultural practices, mineral nutrition, genetic factors and climatic factors.

What are the different stages of postharvest handling?

Diagram 2. Stages of a whole post-harvest system

(01) HARVESTING handling
(03) DRYING transport and distribution
(06) PRIMARY PROCESSING cleaning, classification, dehulling, pounding, grinding, packaging, soaking, winnowing, drying, sieving, whitening, milling

What is the importance of pre-harvest modifiers?

3 Main Reasons: to prevent or correct minor element deficiencies with nutritional sprays as part of the mineral nutrition program. to control diseases, insects and mites with pesticides.

What are pre-harvest losses?

Pre-harvest losses occur before the process of harvesting begins, and may be due to insects, weeds, and rusts. Harvest losses occur between the beginning and completion of harvesting, and are primarily caused by losses due to shattering. Post-harvest losses occur between harvest and the moment of human consumption.

How should harvest be handled?

Three keys to protecting the quality of your produce after harvest are temperature, moisture, and ventilation. Temperature: For produce such as peas and sweet corn, the conversion of sugar to starch is critical to interrupt at harvest. To minimize this conversion, the produce must be cooled immediately.

What are the methods of harvesting?

In general, these are the three different harvesting methods that take place when harvesting fruits and vegetables:

  • Hand Harvesting.
  • Harvesting with Hand Tools.
  • Harvesting with Machinery.

What is pre-harvest modifiers of quality?

>is a existing environment factors during production of the crop and production practices adopted by the growers influence the nature of the commodity at harvest.

Why postharvest handling is important?

DEFINING POST-HARVEST MANAGEMENT The importance of post-harvest management has been established over the years—it strengthens the action chain that produces, transports, and processes food and all other related products that give sustenance to the world population.

What are the 4 causes of harvest loss?

Mainly, during retailing, rotting, mechanical damage, poor handling, improper management of temperature and relative humidity, and hygiene problems during handling are among the major causes of postharvest losses.

What is the most important preharvest pathogen?

Grey mold ( Botrytis cinera ) is considered to be the most important pre- and postharvest pathogen in berry crops, but other preharvest pathogens (e.g., Alternaria, Colletotrichum , and Rhizopus ) can become major problems, depending on other preharvest factors.

Why are there few post-harvest methods for organic fruits and vegetables?

There has been insufficient effort to provide new quality-maintaining technologies for organic products, resulting in few post-harvest methods being available for organic fruits and vegetables. The greatest need is to develop strategies to control post-harvest decay and disorders.

What are the non-chemical post-harvest technologies used in agriculture?

Other non-chemical post-harvest technologies which may be successful will also be discussed, e.g., ethylene and other sprout control technologies, UV-C treatment, heat treatment, anti-microbial surfaces, and natural volatiles. More research is needed on each of these technologies, both singly and in combination with each other.

What do farmers do during pre-harvesting tasks?

During pre-harvesting tasks farmers focuses on selection of crops, land preparation, seed sowing, irrigation, and crop maintenance which includes use pesticides, pruning etc.
