Parsley seeds are commercialized without classification by size during processing, unlike other crops. This classification procedure allows the standardization of seed size for high precision in sowing, disposal of unwanted material, and selection of high quality seeds. The aim of this study was to verify the effect of seed size on germination, vigor, and yield performance of two parsley cultivars. Seeds from eight lots of parsley of ‘Portuguesa’ and ‘Chacareira’ cultivar were separated into three size classes, represented by the seeds retained in the sieves of 0.84, 1.00 and 1.41mm mesh opening. After classification, seeds were evaluated in the laboratory for water content, germination percentage, first count, and thousand seed weight. In the field, the fresh and dry weight of aerial part and the final number of plants (stand) were evaluated after 78 days of sowing. The experimental design was the completely randomized design in an 8 x 3 factorial scheme (eight lots and three sieve opening) with four replicates, for both cultivars. Data obtained were subjected to analysis of variance and means were compared using Tukey test at 5% probability level. It was concluded that the parsley seeds separated by the 1.41 mm sieves showed higher vigor, and consequently, greater success in stand establishment at the field than those separated by other sieve size. The use of sieves in the classification of parsley seeds helps in obtaining lots with superior physiological quality.

Green mustard is one type of vegetable that is easily cultivated and has good prospects to increase farmers' income and community nutrition. Growing media is a material that is useful as a place to stand upright seedlings, to develop seedling roots, to store water, gas, and nutrients needed for seedling growth. The purpose of this study is a). to determine the effect of using a combination of cocopeat and charcoal as a medium for planting mustard greens, b). to get the best dosage of the composition of the growing medium on the growth of mustard greens. The study was conducted in a completely randomized design (CRD) with 4 treatments and 6 replications. The data were analyzed by analysis of variance (ANOVA) and further tested with the Least Significant Difference test (LSD) = 5%. The results showed that the use of cocopeat growing media and charcoal influenced germination and vigor index. Cocopeat and charcoal have a significant effect on fresh and dry weight and chlorophyll content of mustard greens. The mixture of cocopeat growing media and charcoal on P1 did not affect the growth of green mustard on the dry weight. Fresh weight gave a significant effect on K1 and P1 was also significantly different from P2 and P3.

ABSTRACT The germination of seeds is affected by many factors, including water availability and temperature. This study aimed to evaluate the effects of water stress and different temperatures on germination and initial development of S. gardneriana M. R. Barbosa & Peixoto seedlings. The experiment was carried out in a completely randomized design, in a 7 x 4 factorial scheme, with seven potentials (0; -0.1; -0.2; -0.3; -0.4; -0.5 and - 0.6 MPa) and four temperatures (25, 30, 35 and 20-30 °C), with four replicates of 25 seeds. The analyzed variables were germination, percentage of normal seedlings, germination speed index, seedling length (shoot and root) and dry weight (shoot and root). There is a decrease in the germination and vigor of the seeds as the water potential decreases, being less affected under the temperature of 25 °C and very accelerated at 35 °C. The tolerance of S. gardneriana seed germination to water stress is variable between the temperatures and limiting to the formation of normal seedlings from the potential -0.5 MPa at temperatures of 25 to 30 °C and -0.4 and -0.2 MPa for 20-30 and 35 °C, respectively.
