Field Inspection - Objective
The objective of field inspection is to verify the seed crop which is: -
· Raised from seed whose source is approved and which satisfies the requirement of genetic and physical purity.
· Grown on a field area which satisfies the prescribed land requirements as to previous crop(s), to prevent contamination by volunteer plants and disease spread by pathogens.
· Provide with the prescribed isolation; and where applicable, recommended number of border rows.
· Planted in the recommended ratio of male: female parents in seed production involving two parents.
· Properly rouged to remove contaminating factors such as pollen shedders in Bajra and Sorghum. Shedding tassels in Maize crosses, off types, plants/ears affected by designated diseases, objectionable weed plants and inseparable other crop plants at appropriate stages so as to conform to the standards prescribed for these factors.
· True to the varietal characteristics descriptive of the variety.
· Harvested properly to avoid admixture.
· Grown in compliance with other special seed production requirements for the crop concerned.
Procedure for fields inspections differ among crops and among growth stage of the same crop. The following broad principles on inspection methods are common to most crops and stages of growth: -
· The number of inspections indicated in MSCS are the minimum and should be conducted at proper stage.
· The inspection officer should ensure that he is guided by the producer to the correct seed field.
· Inspection of crops pollinated crops at and after commencement of flowering should be made without prior intimation to the producer.
· The producer or his representative should be requested to accompany to the field during the entire inspection and they be shown all the factors observed in the fields and which will be recorded in the inspection report.
· When seed fields of the same class/variety of the same producer are separated by less than 50 meters they can be considered as on fields units for inspection provided, they are of same growth stage and leaves of conformity to standards. If they are separated by more than 50 meters a separate inspection report shall be made for each unit.
· It is compulsory, especially in tall crops like Bajra, Sorghum, Mustard etc. and crops requiring sizeable isolation distances to go completely around the outer boundary of the seed fields and observe it and its border areas once before entering into these fields.
· If one thirds or more of a self-pollinated/cross pollinated crop so heavily lodged that taking counts is difficult, the seed crop may be recommended for rejection/LFR.
· Walk through the entire seed field while taking fields counts and it should not be localized to a portion or a few portions of a field but should be randomly distributed all over the fields and only the prescribed number of counts be taken spread over the entire fields.
· If the plant population in a field is so thin that the entire population is less than the number required for the prescribed number of counts entire population may be counted.
· Counting may be started from any point of the seed fields but spotting a defect and trying to include/avoid it in counts is not desirable and counting in the row/shifting from row to row should be so arranged that the same plant/head is not counted twice.
· Factors counted during inspection need not normally be pulled out, but be shown to the producer to range out such plants.
· If plants/heads of the designated factors which were pulled out by the producer are lying on the ground within out skirts of the seed fields, the producer should be directed to collect and remove them from the field.
· During inspection, if the seed fields is found to be liable for rejection either in part or in full on account of inadequate isolation, the prescribed number of fields counts for the entire area must still be taken for that inspection.
· A Seed crop liable to be partially rejected due to inadequate isolation, further inspection of the entire field (including the affected portion) should be continued according to the prescribed number and procedure and separate counts for the affected area should be mentioned in the inspection report.
· If on the basis of first set of fields counts, the seed crop does not conform to the prescribed standards for any factor, a second set of counts should be taken for the concerned factor, provided the percentage of the first set of counts for the factor is more than the maximum permissible level but not more than twice the maximum permissible level.
· For seed crops involving two parental lines, even if two sets of counts in one parental line show that the field does not conform to the prescribed standards it is necessary to take counts in the other parental line.
· If on the basis of two set of counts the seed crop does not conform to the prescribed standards, further inspections need not be made unless to seed crop is eligible for re-inspection (after removal of contamination factors). If the seed crop is not eligible for such re-inspection then LIABLE FOR REJECTION and final inspection should be recorded in the inspection report.
· If the factor presents beyond the maximum permissible limit as verified by two sets of counts could not have already caused contamination of the seed crop or when contamination has already taken place, if removal of contaminating factors and contaminated materials could make the seed crop conform to the prescribed standards, their removal from the fields may be recommended or permitted. Re-inspection to conform removal and conformity to standards must then be made when re-inspection is permitted and it should be shown in the inspection report.
· Observations made during fields inspection shall be directly recorded on inspection report on the spot and the signature of the cultivator or his representative on the field should be obtained on all copies of inspection report and if, he refuses to sign then it should be indicated in the inspection report as “Refused to sign”.
· Help of Beej Mitra, if any, may be taken on copy of inspection report must then be directly given to the cultivator (Grower) the H.O. copy to reach H.O. within 75 Hrs. of inspection and the regional copy to the concerned agency office.
