In this c<strong>on</strong>necti<strong>on</strong>, the seed quality of farmers’ homegrown seed samples was collected <strong>and</strong> determinedthe quality in the laboratory to st<strong>and</strong>ardize their per<strong>for</strong>mance. The laboratory results showed that theaverage moisture c<strong>on</strong>tents of farmers’ seed were higher than that of Certified <strong>Seed</strong> in all the studyareas. These were 14.6 %, 15.0 % <strong>and</strong> 14.6 % in Rajshahi, Rangpur <strong>and</strong> Jessore, respectively while thest<strong>and</strong>ard moisture c<strong>on</strong>tent of Certified <strong>Seed</strong> is <strong>on</strong>ly 12 % (Table 4.1.39). But the percentage of pureseed was found well above the st<strong>and</strong>ard level. On the other h<strong>and</strong>, the germinati<strong>on</strong> percentage was quitelower (<strong>on</strong>ly 69.1 %) than that of Certified <strong>Seed</strong> st<strong>and</strong>ard (80 %). There<strong>for</strong>e, the quality of f armers’homegrown rice must be improved through ensuring proper post harvest activities in order tosustain/improve crop productivity of cereals in the country.Table 4.1.39 <strong>Seed</strong> quality of farmers’ homegrown rice seed in the study areasFarmers’ Rajshahi Rangpur Jessore Average (all sites)Category % M % P % G % M % P % G % M % P % G % M % P % GLarge 13.6b 98.5b 74.3a 15.2 98.1b 68.8b 14.0b 98.5b 72.2a 14.3b 98.4b 71.8aMedium 14.8a 98.7ab 72.8a 14.2 98.6ab 71.7a 14.3b 98.3b 68.7ab 14.4b 98.5b 71.1aSmall 15.4a 98.9a 66.9b 15.4 99.4a 64.5c 15.5a 99.6a 62.3b 15.4a 99.3a 64.6bAverage 14.6 98.7 71.4 15.0 98.7 68.3 14.6 98.8 67.7 14.7 98.7 69.1CV (%) 4.6 0.3 8.4 6.45 0.5 7.6 3.8 0.5 6.1 - - -Level of sig. ** * ** NS * * * * * ** * **Laboratory St<strong>and</strong>ard of Certified <strong>Seed</strong> 12.0 96.0 80.0Note: * <strong>and</strong> ** significant at 5% <strong>and</strong> 1% level of probability; NS-Not significant;M-Moisture c<strong>on</strong>tent, P-Pure seed <strong>and</strong> G-Germinati<strong>on</strong>4.1.40 Effect of different storage c<strong>on</strong>tainers <strong>on</strong> the seed quality of riceThe seed quality parameters in relati<strong>on</strong> to farmers’ stored seed such as seed moisture c<strong>on</strong>tent, numberof insects present in stored seed, diseased seed <strong>and</strong> germinati<strong>on</strong> were affected significantly due todifferent storage c<strong>on</strong>tainers in all the study areas (Table 4.1 .40). The rice seeds stored into theplastic/metal drums showed the lowest moisture c<strong>on</strong>tent (13.3, 13.5 <strong>and</strong> 12.9% in Rajshahi, Rangpur <strong>and</strong>Jessore, respectively), which was partially identical to polythene lined plastic bag (13.9, 13.8 <strong>and</strong> 13.2%,respectively). The values, however, are all above the critical level of the Certified <strong>Seed</strong>.On the other h<strong>and</strong>, seeds stored in jute bag showed the highest values of moisture c<strong>on</strong>tent (15.5, 15.8 <strong>and</strong>15.6% in Rajshahi, Rangpur <strong>and</strong> Jessore, respectively) that were statistically similar to earthen pot <strong>and</strong>dulee. Rahman et al. (2003 a) in laboratory experiments observed that the germinati<strong>on</strong> of Boro riceseeds, insect damaged seeds <strong>and</strong> number of insects ranged from 86.20 to 93.39%, 0.20 to 0.93% <strong>and</strong>0.20 to 2.07 per 100g rice seeds,, respectively depending <strong>on</strong> the c<strong>on</strong>tainers. Rahman ( 2004) furtherstudied the quality of Boro rice seed stored <strong>for</strong> 18 weeks in two types of painted motka (30 <strong>and</strong> 20 kgsize), metal drum <strong>and</strong> plastic drum. The moisture c<strong>on</strong>tent of the stored rice seeds during storage varied<strong>for</strong>m 10.23 to 13.83% depending <strong>on</strong> storage c<strong>on</strong>tainers <strong>and</strong> length of storage. The lowest moisturec<strong>on</strong>tent was recorded in plastic drum (12.00%), while the highest value (12.91%) was observed inpainted partially filled motka (big), followed by painted fully filled motka (small) <strong>and</strong> metal drum.Higher moisture c<strong>on</strong>tent of seeds recorded in painted partially <strong>and</strong> fully filled motka (big <strong>and</strong> small)46
was probably due to absorpti<strong>on</strong> of some moisture by the storage c<strong>on</strong>tainers prevailing in the storehouse.In c<strong>on</strong>trast, metal drum <strong>and</strong> plastic drum were less permeable, while painted partially <strong>and</strong> fully filledmotka (big <strong>and</strong> small) were more moisture permeable. The seed stored in motka absorbed moremoisture (0.51–0.61% more) compared to metallic <strong>and</strong> plastic drums. This was probably due to the factthat motka was not as airtight as the metal <strong>and</strong> plastic drums.Table 4.1.40 <strong>Seed</strong> quality of rice as affected by different storage c<strong>on</strong>tainers in the study areasC<strong>on</strong>tainerRajshahi Rangpur Jessore% M % In % D % G % M % In % D % G % M % In % D % GPoly+Plastic 13.9ab 2.4b 3.1b 70.5a 13.8bc 2.2b 12.7b 73.9ab 13.2bc 2.4b 2.5b 80.1abDrum 13.3b 1.9b 3.0b 73.0a 13.5c 2.0b 2.4b 76.8a 12.9c 2.1b 2.3b 82.0aJute bag 15.5a 4.1a 8.1a 62.5b 15.8a 5.4a 7.5a 63.1c 15.6a 6.6a 7.3a 68.0cEarthen pot 15.3a 5.3a 7.4a 63.9b 15.3ab 5.3a 7.3a 67.8a-c 14.5a-c 5.8a 7.0a 72.7a-cDulee 15.3a 4.2a 5.8a 64.3b 15.0a-c 4.8a 6.6a 66.8bc 14.7ab 5.2a 6.4a 71.6bcAverage 14.7 3.6 5.5 66.8 14.7 3.9 5.3 69.7 14.2 4.4 5.1 74.9CV (%) 5.9 13.1 16.1 7.6 4.2 12.5 17.1 7.1 4.2 13.2 12.1 6.7Level ofsignificance* ** ** * ** ** ** * ** ** ** *Note: * <strong>and</strong> ** significant at 5 <strong>and</strong> 1% level of probability;M-Moisture c<strong>on</strong>tent; In-Insect affected seed; D-Diseased seed; G-Germinati<strong>on</strong>4.1.41 Dem<strong>and</strong> <strong>and</strong> supply of quality seed of riceIn the private sector, the rice seed producti<strong>on</strong> <strong>and</strong> distributi<strong>on</strong> system started gradually turning towardsan organized from the un-organized state.
