Abstract: To evaluate the antifungal activity of five commercial extracts against Candida albicans in vitro, five commercial extracts obtained from Allium sativum, Chamaemelum nobile, Thymus vulgaris, Zingiber officinale and Ricinus communis were tested at three different concentrations (pure, 1/2 and 1/4) for their antimicrobial activity against C. albicans using agar disc diffusion method. C. albicans was least susceptible to the commercial extracts. The diameter of zone inhibition ranged between 6 and 13 mm. Z. officinale and T. vulgaris extracts appeared to be the most active, while A. sativum, C. nobile and R. communis extracts exhibited most weak antifungal activity against C. albicans. These findings increase the possibility of exploiting these commercial extracts as a safe alternative natural preservative.

Abstract: A series of experiments were conducted to evaluate the plant establishment of white jute seeds collected from five different sources of Bangladesh. The establishment experiments were conducted at greenhouse of BJRI, Dhaka and field of Jute Agriculture Experimental Station (JAES), Manikganj during March to June 2018. The treatments consisted of five different seed sources viz., i) Bangladesh Jute Research Institute (BJRI), ii) Bangladesh Agriculture Development Corporation (BADC), iii), iv) Farmers of two different locations and v) Local market. Farmer’s source was divided into two sub-sources. The sub sources were farmer1 of Faridpur and farmer2 of Rangpur locations. Two different conditions were i) Greenhouse and ii) Field. The four seedlings age were 30, 40, 50, and 60 days. The cv. O-9897 of the Corchorus olitorius L. was used as study material. Randomized completely block design with three replication were followed. Results revealed that O-9897 seed’s seedling growth and dry weight parametersaffected significantly due to seed sources. The shoot height, base diameter, root length, shoot dry weight and root dry weights for O-9897 seed’s influenced significantly due to seed sources in both the condition of greenhouse and field. BJRI and BADC seed sources showed better performance than the others. The attributes showed significant variations for seedling ages in both the conditions also. The highest values were observed in 60 days of seedling age. The interactions of seed sources and seedling ages were highly significant for all the growth and dry weight parameters. The BJRI seeds of 60 days of seedling age performed the highest shoot height, base diameter, and root length, shoot dry weight and root dry weights.

Abstract: Jute seed scarcity in Bangladesh is a major problem for jute growers as jute and allied fibres are the most economic product for the country. Seed is a critical input for jute crop as it is not possible to get both the seed and fibre from the same crop. Organized late jute seed production is lacking in the whole country of Bangladesh. Therefore, updating seed production potential of jute was tested under Jute experimental station of Bangladesh Jute Research Institute. Following the strategy, additional nutrient response to O-9897 and O-72 (Chorcorus olitorius L.) in late jute seed production was assessed in Jute Agriculture Experimental Station (JAES), Manikganj, Bangladesh during the late Jute season. A highly significant effect was observed for plant height, number of branches/plant, number of pods/plant, number of seeds/pod and seed yield with the application of increasing doses of NPK fertilizer. Significantly high seed yields were found with the application of additional 25% NP or 25% NPK with existing recommended doses of fertilizer for late jute seed production for the varieties.

Abstract: With the increase of glyphosate tolerant transgenic soybean cultivation areas, this substance has become the main herbicide for this crop, its use may interfere with the metabolism and nutritional aspects of transgenic plants. In this scenario, the objective of this work was to verify the oil, protein, phytate and amino acid concentrations in glyphosate tolerant soybean cultivar. For this, a randomized block experiment with 6 treatments and 4 repetitions was performed. The analyzed cultivar was genetically modified soybean BRS Valiosa RR. The treatments consisted of glyphosate applied once, that is, respectively in the doses: 1,5 and 2,0 L ha-1 of the commercial product, glyphosate applied sequentially in the doses: 1,5 / 1,5; 2.0 / 1.5 and 2.0 / 1.5 / 1.5 L ha-1 of commercial products, with intervals of 15 to 20 days between applications and control (clean) weeded (without glyphosate application)). Grains were harvested, macerated and 200 mg of each sample was used for extraction of soluble amino acids. After extraction, triplicate aliquots were analyzed to determine total soluble amino acids. For quantitative determination of free amino acids, reverse phase HPLC was used after derivatization with o-ophydialdehyde (OPA) on a Spherisorb ODS-2 (C18) column. OPA derivatives were detected by fluorescence and protein contents were determined by the Kjeldhal and Soxhlet method. The data obtained were submitted to analysis of variance and F test of the statistical program ASSISTAT version 7.7 beta. Significant analyzes were performed by comparing means by Tukey test at 5% probability. In conclusion, the data indicate that although the transgenic event affects some routes, amino acid synthesis was not affected nor in nutritional terms at the glyphosate doses studied.
