Bromeliads have been gaining ground in the economic scenario due mainly to their use as ornamental plants. Bromeliads of the genus Dyckia exhibit different morphologies, and therefore, have relevance in this market. However, some species are threatened due to the extraction of plants from their natural environments. Many of these species are endemic and native to Brazil and there are few studies on their seed physiology; hence, expansion of research into this topic is essential. An alternative for the preservation of such plants is the production of seedlings using seeds. To this end, the objective of this work was to evaluate the physiological potential of seeds of Dyckia brevifolia, Dyckia beateae, and Dyckia excelsa at different temperatures, and determine the number of days to carry out the tests. A completely randomized design was adopted, with three species of Dyckia, analyzed separately, and four temperatures (20, 25, 30, and 35 °C). The following were evaluated: first germination count, germination, germination speed index, length of seedling, and seedling dry weight. The data were analyzed using the Sisvar software for normality and homogeneity, and when the assumptions were met, they were subjected to analysis of variance using the F test (p < 0.05) and the means were compared using the Tukey test at 5% probability. Seeds of D. excelsa emit the radicle more quickly at 20 and 35 °C; however, temperatures of 25 and 30 °C provide better conditions for seedling growth and development. The greatest vigor of D. brevifolia seeds is observed at temperatures of 30 and 35 °C. Seeds of D. beateae emit the radicle more quickly at 20 °C, and the largest seedlings are observed at 35 °C. The first germination count of D. brevifolia, D. beateae, and D. excelsa should be evaluated on the third day after sowing. The germination evaluations for D. excelsa and D. beateae should be carried out on the ninth day after sowing, and those for D. brevifolia on the sixth day after sowing.

A pot experiment was carried out to assess the comparative effects of Trichoderma-enriched biofertilizer and farmyard manure on the growth and yield components of brinjal (Solanum melongena L.). The treatments were T0 (control), T1 (Trichoderma-enriched biofertilizer 5 t/ha), T2 (Trichoderma-enriched biofertilizer 10 t/ha), T3 (Trichoderma- enriched biofertilizer 15 t/ha), T4 (Farmyard manure 5 t/ha), T5 (Farmyard manure 10 t/ha) and T6 (Farmyard manure 15 t/ha). The experiments were laid out in completely randomized design (CRD) with three replications of each treatment. Among the different treatments T3 showed best as much as twice more effective than farmyard manure in increasing growth and yield parameters (plant height, fruit length, fresh weight and dry weight of stem, leaf and fruit) of brinjal plants. Overall, all the treatments increased macronutrients and micronutrients content and uptake by brinjal plants over control. Analysis of post-harvest soil samples also revealed that all the parameters except pH were increased due to different treatments. Dhaka Univ. J. Biol. Sci. 29(1): 1-8, 2020 (January)

Geranium `Yours Truly' in 15-cm diameter plastic pots were greenhouse-grown as single pinched plants in a completely randomized design. Plants were irrigated with 300 mg/liter N from 20N-4.4P-16.6K with leaching fractions (LF) of 0, 0.1, 0.2, and 0.4. There were 24 irrigations during the 8-week study. Plants with LF of 0.2 and 0.4 had 46% greater leaf area, 40% greater top fresh weight, and 37% greater top dry weight than plants with LF of 0 and 0.1. By week 5 the leachate electrical conductivity (EC) for LF of 0.1, 0.2, and 0.4 had increased from about 3 dS/m initially to 12, 8, and 4 dS/m, respectively. At harvest, medium ECe was 7, 4, 3, and 2 dS/m for LF of 0, 0.1, 0.2, and 0.4, respectively. At harvest, medium pH was the same in the top, middle, and bottom thirds of the pot. At harvest medium ECe with LF of 0.1, 0.2, and 0.4 was 47, 68, and 60% lower in the bottom two-thirds of the pot than in the top third. With a LF of 0 the medium ECe was not lower in the bottom of the pot. Minimizing the LF for potted geraniums substantially reduced plant growth.

Katuk (Sauropus androgynus (L.) Merr.) is an indigenous leafy vegetable whose growth is affectedby nitrogen element. This study was aimed at assessing the agronomic performance of four katukaccessions grown with various rates of cattle urine. A factorial completely randomized design wasused. The first factor was katuk accession consisting of four levels, namely Pandeglang, Cianjur,Sukabumi, Leuwiliang, and Kemang. The second factor was cattle urine rates consisting of 5 levels,namely 0%R cattle urine (0.0 ml/plant), 50%R cattle urine (468.75 ml/plant), 100%R cattle urine(937.50 ml/plant), 150% R cattle urine (1406.25 ml/plant), and 100%R urea (8.2 g/plant). Thegrowth and productivity of katuk of Cianjur accession had the highest number of buds, total lengthof buds, number of leaves, number of leaflets, fresh weight, and dry weight. The utilization of 50%R,100%R, and 150%R of cattle urine was found to have higher fresh and dry weight than did theutilization of 0%R cattle urine and 100%R urea. The best quality katuk was Cianjur accessionwhich was found to have the highest vitamin C and chlorophyll contents. No significant effects ofall treatments were found in all vegetative variables except plant height and root fresh and dryweight. It was concluded that cattle urine could be used as a urea substitute.Key words: Sauropus androgynus, number of buds, dry weight, indegenous plant
