Full Text | -2- FIELD OF THE INVENTION This invention relates to an improved method for grainage and a tray used therefor. BACKGROUND OF THE INVENTION Grainage is as such known in the art, comprising the steps of transportation, preservation, emergence, egg laying, washing and egg drying. Transportation involves transferring of cocoons in bamboo baskets, cartons or gunny bags. This allows limited transportation of alive cocoons in the form of garlands. Preservation of alive cocoons is carried out in the form of garlands of length 100-150 cm, which are placed on the stretched wire in the preservation room. The garlands and two consecutive rows of wires are separated by a distance of 4-9 inch and 2- 21/2 feet respectively. As a result of preservation, emergence takes place from the garland. The egg-laying is done in the bamboo monias, earthen cups/pots, plastic boxes as well as in the nylon bags. The eggs are collected mechanically, which are processed in Musling cloth. Finally, spreading of the washed eggs is done on ash or oven/bioting paper so as to obtain the final product. The above process is associated with the following disadvantages: 1. Deficiency of grainage which results in high cost of seed production. 2. More space requirement. 3. Consumption of more time. 4. Decentralization of process, which requires more manpower. 5. It is hazardous. OBJECTS OF THE INVENTION The primary object of the present invention is to propose an improved method for grainage technology and a tray used therefor, which causes convenience in the sorting of alive cocoons. Another object of the present invention is to propose an improved method for grainage and a tray used therefor which facilitates more production per unit area because of more preservation at a time. Further object of the present invention is to propose an improved method for grainage which is simple and easy to conduct. Still another object of the present invention is to propose an improved method for grainage and a tray used therefore which is more hygienic than the prior art thereby avoids dis-insfection. STATEMENT OF INVENTION According to this invention there is provided an improved method for grainage comprising steps of transportation, preservation and emergence wherein the cocoons are disposed in the small holes and big holes of a tray provided with cones, which are closed with perforated cups; egg laying, for which the perforated caps are replaced with the cones; dipping of the tray with the cones in both sides in NaOH solution for 20 seconds and ringing in water is carried out for 5 times for 2 minutes each in 5 different pots separately; dis-infection of the eggs is carried out in 3% Hcl and KOH solution for 30 minutes taken in the ratio of 1:1. ». Further according to this invention there is provided a tray assembly for improved grainage comprising of a base tray provided with a plurality of big and small holes for the placement of cocoons therein, the big holes are disposed with a plurality of cones, perforated caps and pathological caps. BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWING Further objects and advantages of this invention will be more apparent from the ensuing description when read in conjunction with the accompanying drawings and wherein: Figure 1 shows: plan and front elevation of the tray of the present invention. Figure 2 shows: sectional view of the tray. DETAILED DESCRIPTION OF THE INVENTION WITH REFERENCE TO ACCOMPANYING DRAWING. This invention proposes improved grainage technology which is conducted in a tray of the present invention. The tray is disposed with a plurality of big and small holes (1 and 2) symmetrically. The invention is carried out in 6 stages namely, transportation, preservation, emergence, egg laying, egg washing and egg drying as it was in prior art; In the process of transportation, the big holes of the tray are fixed with the cones (3) and tasar cocoons are placed in the small holes. This step is followed by placement of second tier of cocoons inside the cone on its reverse side, which is closed with perforated cup. The trays are piled after filling each tray. The cones are provided with a plurality of slits on their circumference and perforations on their top portion. The cocoons in the tray are allowed for preservation and emergence for a prescribed time period with the cones and perforated caps. During preservation, each tray is put on the rack in the preservation room. The emergence is followed by egg laying for which the perforated cap is replaced with cone. Thereafter, the moth are taken to the Examination room for testing, which confirms the dis-infection of the moth. This test is carried out in an other tray, the big holes of which are fixed with the pathelogical cups provided with pastals. The pathelogical cups are used for moth smear preparation. The infected eggs are taken out of the tray. Subsequently, the tray with eggs and cones on both sides is dipped in NaOH solution for maximum 20 second and thoroughly ringed in water for atleast 5 times for 2 minutes each in 5 different pots separately. Ultimately the eggs are dis-infected with 3% Hcl and 3% KOH solution for 30 minutes taken in the ratio of 1:1 and the dis-infected eggs are washed with water and allowed to dry in-situ condition. The eggs are prepared in the cellular condition which can be collected by taking out the lower cones for mass production and supply. The base tray is made of for example: plastic (HDP/LDP) or PVC. The collars are extended upwardly and downwardly so as to facilitate the placement of the different components like cones etc. The big holes are provided in for example: 6X7 rows. The small holes are extended in one direction having collar provided in for example: 6X5 rows. In the present invention, the upside down placement of cocoons against the traditions enables smooth emergence and conserves energy of moth resulting in better fecundity. This is in confirmation with other sericigenous insects such as Bombyx mori. The statistically pooled data on emergence efficiency, crippled moth, pupal mortality and egg laying co-efficient are presented in Table - 1 given below:- The perusal of data indicates that there is non-significant difference at 5% level in emergence efficiency of both the sexes, mean emergence of male and female crippled moth and egg laying coefficient under existing practices. However, moth and pupal mortality showed statistically significant difference at 5% level. It adjudicated that the application of TGT is at par with the existing grainage practices. It indicated statistically significant reduced pupal mortality (7.77 ± 2.37) and moth mortality (0.92 ± 0.21) in non-diapausing population against control i.e 26.63 ± 2.33 and 2.28 ± 0.54 respectively. The perusal of Table 3 indicates that a total of 38660 cocoons processed and produced 7965 dfls with 4.85:1 (cocoon dfl) is at par with expected result of 5:1. The second crop grainage gave 3.86:1 in DTv and 4.9:1 in DBv indicates better results which can be further improvised with TGT applications. The economics of TGT projections against the existing practices to adjudicate the unit cost of tasar seed production is depicted in Table 2. It is note that with TGT applications, the unit cost of BV and TV dfls comes to Rs. 3.51 and Rs. 2.86 respectively against Rs. 4.35 and Rs. 3.50, with existing technology. With introduction of total modality in grainage has an economic efficiency of 19.3% and 18.29%. This also reduces drastically the capital expenditure on infrastructures with partial reduction in working capital. It is to be noted that the present invention is susceptible to modifications, adaptations and changes by those skilled in the art. Such variant embodiments employing the concepts and features of this invention are intended to be within the scope of the present invention, which is further set forth under the following claims:- WE CLAIM; 1. An improved method for grainage comprising steps of: transportation, preservation and emergence wherein the cocoons are disposed in the small holes and big holes of a tray provided with cones, which are closed with perforated cups; egg laying, for which the perforated caps are replaced with the cones; dipping of the tray with the cones in both sides in NaOH solution for 20 seconds and ringing in water is carried out for 5 times for 2 minutes each in 5 different pots separately; dis-infection of the eggs is carried out in 3% Hcl and KOH solution for 30 minutes taken in the ratio of 1:1. 2.
