This study was undertaken to find out national level changes in area, production and yield of two major staple crops wheat and potato in Bangladesh. The time series of secondary data was collected from yearbook of agricultural statistics under Bangladesh Bureau of Statistics (BBS) and used for the statistical analysis during the thirty-year period of 1989/90-2018/19. Moreover, selected data were divided into two groups and regarded as segment (1989/90-2003/04, 2005/06-2018/19) to examine the significant level in each crop. The results of different statistical techniques showed that wheat cultivated area and production were satisfactory level but yield was not too much standard in context of country demand. In the case of potato, yield as well as cultivated area and production were crossed the significant level and fulfilled the demand of population. In recent few years, the ratio of potato production rapidly increased, compared with the cultivation area. Based on segment (period) analysis, at the first half wheat production was always below, compared with the area but second half nine years saw slightly improved. On the other hand, in both segment potato growth rate in area, production and yield were increased throughout the study period. The highest instability was also shown in area, production and yield of potato during whole as well as segmented period. There was always a positive relationship between country’s demand and supply. Both wheat and potato are considered as staple crops and based on the productive capability over cultivated area, potato showed the higher productivity for the country of Bangladesh. In consequences, potato consuming demand also rapidly increased all over the country, compared with past respectively.

Background : The study is investigated the development of high-quality standard variety, character of gene resources, growth and yield production to collecting varieties in Agastache rugosa O. Kuntze containing antioxidant agriculturally. Methods and Results : Character of gene resources investigated collecting 16 varieties (Jeonnam Naju 1, 2, 3 (NJ), Gwangyang 1, 2 (GY), Sooncheon 4 (SC), Boseong 1, 2 (BS), Yeosu (YS), Jangheung (JH), Jindo (JD), Gyeongnam Hamyang (HY), Gyeongbuk Bonghwa (BH), Chungbuk Eumseong (ES), Cheongju (CJ), Gangwon Cheolwon (CW). Method of cultivation were conducted under sowing dates of plant a seedling were April 24. Transplanting with Agastache rugosa O.K. seeds in June 27 by growing pot seedling for 60 days in 2017. Fertilization application were standard application (N-P-K-Compost applied at 12-16-10-600 ㎏․10a−1). N-K applied at 60% of basal fertilizer, 40% of top dressing were two times (N-K) application. Planting density were spaced 30 ㎝ apart in rows 20 ㎝ apart with with non-woven fabric mulching cultivation. Plot design randomized block 3 repetition. Conclusion : Endemic characteristics of gene resources to collecting variety in leaf color (light green), leaf pliable (softness) appeared 8 lineage, leaf color (deep green), the contrary leaf pliable (roughness) showed 8 lineage. Flower color bloomed in light purple 8 lineage flower deep purple color come into 8 lineage. Also, the period of maturity ripened Sept. 27 - 31. on 8 lineage (BS2, GY1, JD, HY etc.). 3 lineage (YS, CJ, CW) attained to maturity on Oct. 14 - 16. Growth of aerial part increased on long length, large width of leaf, heavy dried weight of leaf and weight of seeds 10 lineage SC4, GY1, 2, NJ2, 3, BS1, 2, CJ, ES, BH etc. but short length, small width of leaf, declined in light dried weight of leaf and weight of seeds 2 lineage YS, CW.

Background : This study for the stable production and supply of seeds of Angelica gigas Nakai(Man-chu Korean Angelica), when seeds harvested using nets, seed productivity was investigated. Methods and Results : Planting density is 50 × 25cm, Fertilizer per 10a was sprayed amount of N-P2O5-K2O = 16-17-10kg. And the amount of compost per 10a was sprayed 3000kg. Seed harvesting nets were used for a time formed the endosperm of the seeds (later in mid-August to late). And net for seed production was used for onion nets (at least 13 × 18cm). Shoot growth conditions were as follows. Bolting rate was 89.0% in the untreated, the treated group was 93.1%. The length and thickness of each stem was 129.3 ~ 130.8cm, 1.8cm. The number of nodes per plant was 6.7 ~ 7.5 pieces, and the number of petiole was 14.8 ~ 15.5 per plant. The number of umbel was 10.3 ~ 11.1 piece per plant, and number of deleted umbel was 7.1 ~ 7.2 piece. Seed weight per plant was 24.2g of the net treatment, but ripening seeds 19.6g, 1000 grain weight were all treated and untreated 2.8g. The total seed weight per plant, the net treated was 24.2g, was the weight of the ripening seeds 19.6g. The weight of the ripening seeds were heavier than those of the control. However, the weight of 1000 grain were both treated and untreated 2.8g. When treated nets, the total seed yield per 10a was 88.0kg production, increased by 60.9% compared to untreated. In addition, the ripening seed production per 10a was 71.5kg production, increased by 50.1% compared to untreated. Researching after germination Seed Production, germination rate was 50.8% in the control group and the treatment group was 54.9%. When applying the germination rate, high-quality seed production per 10a was able to produce 39.2kg, compared to control obtain the results increased by 65%. Conclusion : Through the above results, When producing angelica seed, use of net for seed production is thought to be used as a way to prevent early shattering and insect damage.(True bug, etc.).
