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.

Moler disease is the primary disease that disturbs the shallot’ cultivation. Hence, it is beneficial to have preventive measures to mitigate the risk and to improve growth. The research objective is to know the effectivity of Trichoderma harzianum suspension as a bio-fungicide and bio-stimulator. The study used seven treatments, i.e., immersion of shallot seeds on negative control (distilled water), positive control (synthetic fungicide+ZPT 1g/liter), T.harzianum suspension with different concentrations of 2 ppm, 4 ppm, 6 ppm, 8 ppm, and 10 ppm, assigned in a Completely Randomized Design (CRD). Treatment that results in a significant level will be continued to the Least Significance Different (LSD) 5% test. The observed variables are the intensity of moler disease and the growth of shallot seeds. Experiment results show the significant difference between treatments. The optimal treatment to reduce the percentage of moler disease intensity is the immersion of shallot seeds in 10 ppm-concentrated T.harzianum suspension, while to improve the shallot growth is in 8 ppm-concentrated T.harzianum suspension. The intensity of moler disease has a negative correlation to the plant’s height and leaf’s diameter but shows no correlation pattern to the number of leaves, wet weight, dry weight, and length of roots.
