Germination, vigor and pathogen incidence in broccoli seed treated with Carboxin + Thiran

The purpose of treating seeds chemically is to eradicate their pathogens and/or protect them against soil pathogens, mainly by germination time. However, there is little research on vegetables investigating the effect of this treatment on seed quality. Therefore, this study evaluates the effects of Carboxin + Thiram doses on germination and vigor of three lots of broccoli seeds, as well as on the incidence of fungi in...

Micropropagation of Plectranthus edulis (Vatke) Agnew from shoot tip and nodal explants

Plectranthus edulis Vatke belongs to the family of Lamiaceae, which occurs both as a wild and cultivated species. The major constraint in the cultivation of P. edulis is its low productivity due to shortage of planting materials and incidence of pests and diseases. In this study, an efficient protocol was established for the micropropagation of P. edulis germplasm using shoot tip and nodal explants. Explants were...

Effect of base saturation and nitrogen dose on cultivation of crambe

The grain production potential of crambe reported in literature may vary from 1000 to 1500 kg ha-1, but there are not yet any recommendations regarding specific nitrogen (N) fertilization for this crop. The objective of this study was to evaluate the effect of base saturation and the addition of N doses on plant development and productivity of crambe. This study was developed at the São Tomaz Jatobá farm...

Estimates of genetic components for yield and yield related traits of Tannia (Xanthosoma sagittifolium (L.) Schott) genotypes at Jimma, Southwest Ethiopia

Tannia is one of the most important root and tuber crops for food, feed and industrial applications worldwide. However, the progress to variety development in Ethiopia is so slow due to lack of adequate germplasm characterization and agronomic evaluation for yield and quality. Therefore, a total of 64 tannia genotypes were studied to determine the extent of genetic variability among genotypes at Jimma agriculture...

Mathematical modeling and thermodynamic properties for drying soybean grains

The aims of this work were to adjust different mathematical models to experimental data describing the drying of the Valiosa cultivar soybean grain, to determine and to evaluate the effective diffusion coefficient and to obtain the activation energy and the thermodynamic properties of the drying process under different air conditions. The Valiosa cultivar soybean grains, with an initial moisture content on a dry basis...
