Sausen, Darlene; Neis, Franciele Antônia; Uliana, Suzi Cerezer; Farias, Júlia Gomes; Hildebrand, Hilda Soriani; Mambrin, Ritieli BaptistaThe development of more efficient plants in the use of nutrients will be fundamental for agriculture in the coming years. The objective of this work was to define a physiological marker of the nutritional status of P for potato clones cultivated off-soil and in vitro, in order to facilitate the selection process of more efficient clones in the use of P. For this, two experiments were carried out with seven pota...
Wheat Fundacep Horizonte competitive ability under competition with ryegrass
Tarouco, Camila Peligrinotti; Agostinetto, Dirceu; Langaro, Ana Claudia; Nohatto, Marcos André; Mariani, Franciele; da Silva, Bruno MonksThe weeds present in wheat compete for several factors negatively impacting on cropproductivity. In this context, the goal of the study was to morphologically analyze wheat andryegrass in response to stress caused by competition between crop and weed. The experiment wasconducted in completely randomized design with 4 replications in a replacement series with apopulation of 64 plants per pot. Treatments consiste...
Seletivicty of eucalyptus genotypes to herbicides rates
Agostinetto, Dirceu; Tarouco, Camila Peligrinotti; Markus, Catarine; de Oliveira, Ezequiel; Silva, José Matheus Betemps Vaz da; Tironi, Siumar PedroThe aim of this work was to quantify the herbicide selectivity applied at post-emergence of eucalyptus in different rates. The experiment was conducted in greenhouse conditions in the period from January to March 2007 at the Faculdade de Agronomia Eliseu Maciel in Universidade Federal de Pelotas – Capão do Leão-RS. Experimental design was completely randomized, with four replications. Treatments were in a facto...
