The selection of yerba mate superior genotypes, based on each plant leaf weight, is based on genetic parameters obtained from experimental plantations and it is practically impossible from the fourth year of age. Therefore, we estimate genetic parameters and check the feasibility of selection through notes and weight estimates of each tree at 18.5 years of age. The genetic material consists of a combined trial of provenances and progenies of half-sibs with 140 progenies from 7 provenances, installed in Ivaí, Paraná, Brazil, in a randomized block design with 10 repetitions. The genetic control of leaf production is of low magnitude (h2a = 0.175042 ± 0.0393) revealing high influence of the environment. The additive genetic correlations between the real weight of leaves × notes and real weight of leaves × visually estimated weight were of high magnitude (higher than 88%). Thus, the selection based on the leaves weight can be carried out without major losses in genetic gains by both methodologies when the purpose is the sexual selection, in which case the sort order has no importance. In the case of vegetative propagation, aiming clonal plantations, in which only the plants with the highest genotypic values should be selected, the selection by means of notes and leaves weight estimates proved to be inefficient. |

This study determined the mineral composition of sorghum Ponta Negra and its silage, irrigated with different leaching fractions with brackish water. Two experiments were performed: The first step evaluated the sorghum irrigated by four leaching fractions with brackish water (0, 5, 10 and 15%) and 4 repetitions. In the second experiment, sorghum was harvested at 101 days to make experimental silos which, according to the leaching fractions, four treatments were formed, with 5 repetitions each, totaling 20 silos stored for 90 days. A randomized block design was adopted. Different leaching fractions with brackish water provided a quadratic behavior was observed for Nitrogen (N), Phosphorus (P) and Sulfur (S) on the sorghum plant. A positive linear effect was observed for Potassium (K), Calcium (Ca), Magnesium (Mg) and Sodium (Na) with the increase in leaching fractions with brackish water in the irrigation of sorghum plant. Regarding sorghum silage, the leaching fractions with brackish water promoted a positive linear effect for the N content and quadratic effect for P, K, Ca, Mg and Na. Despite the high content of soluble salts in the water resources available in arid and semi-arid regions, the use of irrigation leaching fraction has been considered a viable alternative for the production of tolerant forage crops. |
