MANUAL ON STANDARDS OF MUSTARD AND RAPESEED

 

1. INTRODUCTION

 

            Promotion of standardization and grading of agricultural commodities is an important aspect of agricultural marketing. The agricultural commodities are heterogeneous and hence it is very essential to grade these commodities as per standards to command better price either at domestic or international market.  Sale of  Mustard and Rapeseed is offered on the basis of variety, wholesomeness, appearance, colour, presence of foreign matter, damaged seeds, broken seeds, admixture of inferior variety, moisture, harmful contaminants, etc.  A quality grain is that which meets the end user specifications with respect to range of pre-determined Quality and Safety standards.

 

2. OBJECTIVE

 

The Manual has been designed with the objectives to

                                 i.            Create awareness about standards prescribed by various organizations for domestic and international markets so as to raise quality consciousness among the farmers, entrepreneurs and other market functionaries with the objective to equip them better to face the global competition in the post WTO era.

                               ii.            provide details of various parameters responsible for quality; and

                              iii.            describe the advantages of grading & standardization so that farmers may get prices commensurate with the quality produced by them.

 

3. IMPORTANT PARAMETERS RESPONSIBLE FOR QUALITY

 

3.1 Following Parameters are important in determination of QUALITY of Mustard and Rapeseed:

 

·         Foreign matter

5. STANDARDS APPLICABLE FOR STORAGE OF MUSTARD AND RAPESEED

 

5.1 CENTRAL WAREHOUSING CORPORATION (CWC) :  The CWC works as an agent of the government for  purchase, sale, storage and distribution of agricultural and industrial commodities, seeds, fertilizers and notified commodities for individual, cooperatives and other institutions in the country.  CWC provides modern efficient warehousing to ensure maximum returns to the growers with better opportunities. It provides scientific facilities to the farmers for the stock of agricultural produce at a reasonable cost.   CWC issues Warehouse Receipts to a person depositing goods in the warehouse.  The banking institutions accept the Warehouse Receipts as co-lateral security for grant of loans to the holder of the Warehouse Receipt on its being endorsed and delivered to them.   Thus, warehousing plays an active role in marketing and also provides socio-economic gains to the farmers, who otherwise get exploited by the middlemen and are forced to have distress sales.

6.   STANDARDS APPLICABLE FOR DOMESTIC MARKET

 

6.1 The Prevention of Food Adulteration Act, 1954 (PFA Standards)

Prevention of Food Adulteration Rules, 1955 (PFA Rules) have been notified to carry out the provisions of the Prevention of Food Adulteration Act, 1954. These rules define the standards of quality and fix the limit of variability permissible in respect of article of food. These rules also provide guidelines for packing and labeling of an article of food. Standards framed under the provisions of the Rules are popularly called PFA standards. PFA standards prescribe minimum limit for Quality as well as Safety parameters. PFA standards are minimum standards and are mandatory.  They do not differentiate between Quality.  Food articles being sold in the market should comply with PFA standards.   Standards of Mustard and Rapeseed prescribed in PFA Rules, 1955 are as follows :

7.STANDARDS FOR GRADING

 

7.1 GRADING - Grading provides description of the quality of the consignment and assists in the formation of a legally binding agreement. It facilitates proper marketing of agricultural commodities.  It also ensures that agricultural commodities move through the market faster and  without obstructions.   This also facilitates transactions without physical verification by the distant buyers.

 

 

 

Advantages of Grading

 

-          It brings confidence between the buyer and the seller.

-          It facilitates interstate and international marketing.

-          Disputes in the market can be solved amicably.

-          Stability of the price is ensured.

-          Farmers can take loans easily from the banks on the basis of grades of produce stored in the godown

-          Arbitrary fixation of price by middlemen is eliminated.

-          Brings about improvement of the crop.

-          Reduces risk of producer and seller in transactions.

-          Future marketing is facilitated. Grades become a commercial measure of quality.

-          It also helps in implementation of contract farming.

 

7.2  AGRICULTURAL PRODUCE (GRADING & MARKING) ACT, 1937 (AGMARK STANDARDS).

 

Standards of various agricultural commodities prescribed under the provisions of the Agricultural Produce (Grading & Marking) act, 1937 are popularly called AGMARK Standards.  AGMARK standards comply with minimum standards of quality & safety prescribed in Prevention of Food Adulteration Rules, 1955.  In addition AGMARK standards differentiate between quality by having three grades for Mustard and Rape seed.  The grades are differentiated on the basis of foreign matter, dead badly discoloured and damaged, unripe  shriveled and slightly damaged ,small atrophied seeds, admixture of other varieties of seed etc .
