| The objective of this work was to evaluate the root system distribution and the yield of 'Conilon' coffee (Coffea canephora) propagated by seeds or cuttings. The experiment was carried out with 2x1 m spacing, in an Oxisol with sandy clay loam texture. A randomized complete block design was used, following a 2x9x6 factorial arrangement, with two propagation methods (seeds and cuttings), nine sampling spacings (0.15, 0.30, 0.45, 0.60, 0.75, and 0.90 m between rows, and 0.15, 0.30, and 0.45 between plants within rows), six soil depths (0.10-0.20, 0.20-0.30, 0.30-0.40, 0.40-0.50, and 0.50-0.60 m), and six replicates. Soil cores (27 cm3) with roots were taken from 12 experimental units, 146 months after planting. The surface area of the root system and root... |

| A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots. The research was established in a completely random design with ten treatments and three replicate pots. The plants were harvested four weeks after sowning, and leaf area per plant (LA), root volume (RV), longest root length (LRL), plant height (PH), fresh (RFW) and dry weight (ROW) of roots, shoot dry weight (SOW), RDW/SDW ratio, and total dry matter production (TDM) were determined. Significant varietal differences for all characters were found, except for LRL. The data obtained allowed to identify Cargill-163 as a poor genotype at low water supply. Danac-3006, FM-6,... |

| Morphological variables such as phytomass, plant height, leaf area, number of leaves, have been used to express the influence of mineral nutrients on plant growth patterns, since the vegetative development responds, in general, favorably to fertilizer applications. This work evaluates the effect of P on both, some morphological characteristics and total [P] in the shoot of eight grain sorghum (Sorghum bicolor L. Moench) genotypes. Genetic materials were grown in nutrient solution under three concentrations of P (0; 0.5 and 1.0 mmol L-1). Plants were harvested 41 days after sowing, and leaf area per plant (LA), number of leaves (NL) per plant, root volume (RV), plant height (PH), root dry matter (RDM), shoot dry matter (SDM), total dry matter (TDM), RDM/SDM... |
