Agrupamento de colheitas de tomate e estimativas do tamanho de parcela em cultivo protegido

Abstract: Para verificar qual a interferência da variabilidade das estimativas dos valores usados para determinação do tamanho de parcela com simulações de diferentes números de plantas por parcela e agrupamentos de colheitas, realizou-se um trabalho com três experimentos de tomate no Departamento de Fitotecnia da UFSM. Em dois experimentos foram utilizados túneis plásticos, com irrigação por gotejamento, camalhões com mulching preto de PEDB, três linhas de cultivo, 24 plantas por linha, espaçamento entre plantas 0,8 m … Show more

“…Some studies have been carried out to estimate plot size in the sweet pepper (LORENTZ; LÚCIO, 2009;LÚCIO et al, 2004), tomato (LÚCIO et al, 2010(LÚCIO et al, , 2012, lettuce (LÚCIO et al, 2011) and green bean (SANTOS et al, 2012). However, these studies were not concerned with investigating whether the sizes used in the uniformity trial were sufficient to accurately estimate the plot size.…”

“…Cargnelutti Filho et al (2004) obtained higher CV% values at the beginning and end of the tomato harvest, because the beginning and end of the fruit production were not uniform among the plants. In another study on tomatoes, Lúcio et al (2010) found that the largest production of fruits occurred mid-way and at the end of the production cycle, and that the variability increased due to physiological aspects of the plants, because they go into a state of senescence.…”

“…LÚCIO et al (2010), also with tomatoes, seen that the bigger production of fruits is focused mainly at half productive cycle and that in the end of the cycle the Table 1 -Harvesting groups simulated for the crops of zucchini. In all the cases, it was possible to identify the VC minimum point.…”

“…This is because many times the plants do not have fruits or they are not appropriate for being harvested yet, resulting in null values of production and increasing variability inside the crop rows. LÚCIO et al (2010) also realized that there was a reduction in the magnitude of this indicator of accuracy due to e filling out of gaps formed by plants that were not harvested, resulting in the increase of the mean.…”
