The experiment was conducted to study the variability among seven parental genotypes and their twenty one F progenies of Brassica rapa at Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh. 2 Results showed that seed yield plant had significant positive association with number of primary branches 1 plant , number of secondary branches plant , number of siliquae plant . Path co-effici...

The study was attempted with an objective to check the purity of commonly used farmer’s rice seed stock. Assessment of varietal purity of collected 76 rice genotypes showed that there was a variation among the genotypes for varietal purity. Thirty-two genotypes showed 100% varietal purity and forty-four genotypes were contaminated with different types of offtypes. The lowest varietal purity was...

Seed storage experiment was carried out to investigate the most appropriate period of storing and preserving soybean seed quality under ambient conditions. Germination percentage, seed vigour, moisture content, 1000 seed weight, protein and oil contents were assessed before storage (control), three months (90 days) and six months (180 days) after storage. The results indicated that soybean seed...

This research was made during the 2011 and 2012 growing periods in the trial filed of "Research Station for Management of Soil Water and Desertification" according to “Randomized Blocks Design” with 3 replications. Research material was the following chickpea genotype; CA119, CA128, CA149, CA150, CA222, CA250, CA254 and other 2 commercial varieties named as Gökçe and Yaşa. Some agronomical char...

Orchid seeds, which are produced in abundance, are particularly small and light. Some orchid species are anemochorous, i.e., bear seeds that are dispersed by wind. To characterize the seeds of Japanese orchids, we measured the size of seeds and embryos of 68 Japanese orchid species. Most orchid seeds had a length of 0.3 to 2 mm and a width of 0.07 to 0.2 mm. Embryo length and width were 0.1 to ...

The study diagnosed engineering properties on varying moisture content of sunflower seed and kernel from 7.6 to 25% (wet basis). On increasing moisture, dimensional values increased for both seed and kernel. Bulk density, true density and porosity were found higher for kernel as compared to seed at each moisture content. On increasing the moisture content from 7.6 to 25%, true density, porosity...
