Optimizing growth, yield, and nutritional quality of Chinese cabbage through vermicompost and reduced fertilizer application in organic farming systems
Chinese cabbage, though less prominent in Bangladesh, has shown potential for successful cultivation in theregion. This study aimed to assess various cultivars’ efficacy on Chinese cabbage growth, yield, and qualitywithin an organic farming system. A field experiment employed a for two consecutive years, investigating thecombined impact of cultivar and vermicompost with reduced fertilizer levels on yield. Three cultivars viz., BARIChinakopi 1, Blues, and Retasi, were tested along with four fertilizer levels namely, recommended NPK (control);80% NPK + vermicompost 6 t/ha; 70% NPK + vermicompost 8 t/ha; and 50% NPK + vermicompost 10 t/ha.Results demonstrated that cv. Blues, treated with 50% NPK + 10 t/ha of vermicompost, exhibited significantenhancements in various parameters compared to the control group. Notably, the treated var. Blues showcasedincreased plant height (43%), head diameter (46.3%), dry matter (71.2%), and gross yield (72.2%) at harvest.Moreover, var. Blues treated with vermicompost at 10 t/ha displayed elevated levels of vitamin C (28%),β-carotene (96.3%), Ca (7.1%), Mg (18.4%), P (5%), K (10.5%), Fe (13.1%), and Zn (21%) compared tocontrol. These findings suggest that utilizing 50% NPK + vermicompost at 10 t/ha significantly enhances Chinesecabbage growth and quality, particularly in cv. Blues. Incorporating this treatment method could effectivelyelevate both production yield and crop quality, providing valuable insights for organic farming practices

Impact of culture vessels on micro-morphological features of in vitro Dendrobium Sabin Blue orchid
Different designs of the plant tissue culture vessel, such as size, material, and shape, may alter its microenvironment atmosphere. The present study was conducted on protocorm-like bodies (PLBs) of Dendrobium Sabin Blue orchid to determine the development of PLBs on plastic and glass culture vessels of different sizes. PLBs were cultured in half-strength Murashige and Skoog (MS) medium with the same initial weight of 0.5 g in 10 replicates.
The growth index of the PLBs was calculated after 11 weeks to study their growth in every vessel; additionally, biochemical analysis was performed to determine carbohydrate content, proline concentration, and photosynthesis pigments in the PLBs. Scanning electron microscopy (SEM) was performed to study stomata development on PLBs in each vessel, and histological analyses were conducted to study the cell structure. Overall, the PLBs cultured in a large 470 ml plastic vessel showed successful growth with a high growth index, high carbohydrate content, low-stress condition, and high chlorophyll content. SEM confirmed that the presence of trichome
and rhizoid in PLBs cultured in the 470 ml plastic vessel. Histological analysis showed the formation of the shoot on the PLBs and the presence of starch granules. Thus, the use of plastic as a culture vessel provides a good impact for culturing PLBs and has low cost
