This study was conducted in areas of vegetable production in tropical Brazil,with the objectives of (i)measuring the variation in ??15 N in soils, organic N fertilizer sources and lettuce (Lactuca sativa L.) from different farming systems, (ii) measuring whether plant ??15 N can differentiate organic versus conventional lettuce and (iii) identifying the factors affecting lettuce ??15 N. Samples of soil, lettuce and organic inputs were taken from two organic, one conventional and one hydroponic farm. The two organic farms haddifferentN-sources with ??15 Nvalues ranging from0.0 to+14.9‰(e.g. leguminous greenmanure and animal manure compost, respectively), and differed significantly (P < 0.05) in lettuce ??15 N (+9.2±1.1‰ and +14.3±1.0‰). Conventional lettuce ??15 N (+8.5±2.7‰) differed from hydroponic lettuce ??15 N (+4.5±0.2‰) due to manure inputs. The N from leguminous green manuremade a small contribution to the N nutrition of lettuce in the multi-N-source organic farm. To differentiate organic versus conventional farms using ??15 N the several subsets ofmode of fertilization should be considered. Comparisons of ??15 N of soil, organic inputs and lettuce allowed a qualitative analysis of the relative importance of different N inputs. |

Our aim was to evaluate the use and application of different nonlinear mixed models, as well as to compare them with approach in nonlinear fixed models, for describing the growth curve of meat-type quails according to gender. A total of 15,002 and 15,408 records of males and females were used, respectively. The body weights were regressed on age of the animals using nonlinear models (Brody; Gompertz; Logistic, Morgan-Mercer-Flodin, Richards and Von Bertalanffy). All model parameters were considered fixed, whereas parameters related to asymptotic weight and maturity rate were fitted as random effects. The Bayesian Information Criterion was used to find the model of best fit. For both genders, the model that used the Morgan-Mercer-Flodin function with the inclusion of asymptotic weight as a random effect was considered the best-fitting model because it reduced the residual variance and increased the accuracy. Based on the lower absolute growth rate and growth velocity of male quails compared to that of females, it can be inferred that males should be slaughtered later. Given the results of this study, it can contribute to the current knowledge about animal yield, specifically at the best moment to slaughter and, this sense, improv the quality genetic of the populations in time. |
