| ABSTRACT This study aimed to adjust the Gompertz and Logistic nonlinear models for the fresh and dry matter of aerial part and indicate the model that best describes the growth of two rye cultivars in five sowing seasons, as well as to characterize the growth of the cultivars regarding the fresh and dry matter of aerial part. Ten uniformity trials were conducted with the rye crop in 2016. A weekly sampling and evaluation of 10 plants per trial was performed from the time the plants presented one expanded leaf. For each plant, the fresh and dry matter of aerial part were weighed. The Gompertz and Logistic models were adjusted to the accumulated thermal time based on the measures of each trait in each assessment. Also the parameters a, b, and c for each... |

| Com o objetivo de determinar o efeito da densidade de plantio sobre o crescimento da planta, a produtividade e características químicas relacionadas à qualidade organoléptica das frutas da cultivar de morangueiro Camino Real em sistema hidropônico do tipo NFT, diferentes densidades de plantio foram avaliadas: 15,0; 12,5; 10,7 e 9,3 plantas m-2, correspondentes ao espaçamento entre plantas de 0,25; 0,30; 0,35 e 0,40 m, sendo fixado o espaçamento entre linhas de 0,18 m. O sistema NFT foi constituído por bancadas de telhas de fibrocimento de 1,10 x 2,44 m, considerando-se cada ondulação côncava da telha como um canal de cultivo. O transplante foi realizado em 26-04-2010, encerrando-se o experimento em 05-01-2011. Avaliaram-se a matéria fresca e seca de... |

| ABSTRACT The aim of this study was to determine the optimum plot size to evaluate the fresh matter of aerial part of dwarf pigeon pea (Cajanus cajan (L.) Millsp), cultivar IAPAR 43 (Aratã), in scenarios formed by combinations of numbers of treatments, number of replications, and precision levels. The fresh matter of aerial part was weighed on basic experimental units of 1 m × 1 m in three uniformity trials with size of 24 m × 12 m (288 m2 in each trial). The soil heterogeneity index of Smith was estimated. Also, the optimum plot size was determined by Hatheway’s method in scenarios formed by combinations of i treatments (i = 5, 10, 15, and 20), r replications (r = 3, 4, 5, 6, 7 8, 9, and 10), and d precision levels (d = 5%, 10%, 15%, 20%, 25%, and 30%).
