Sistemas de cultivo e espaçamentos em cultivares de trigo irrigado

Abstract

The purpose of this work was to study the culture systems in two sowing spacing for the recommended wheat´s cultivars in the state of Minas Gerais in Lavras-MG. The experiment used two randomized complete blocks desing with subplots, 16 treatments, 4 replications carried out in two rows, in one of those was used no tillage and in the other one was used a conventional planting system. In the plots were used distribution of the spacings 17 cm and 34 cm between the rows and in the subplots "Embrapa 22", Embrapa 41", "Br 26 São Gotardo" and "IAC 24 Tucuruí " cultivars. The agronomical characteristics such as onset and ending standard, plants heigt, number of grains per spike, the weight of 1000 grains, the hectoliter weight and grains yield were studied. The culture system no tillage and conventional one did not interfir in the cultivars grain yield. The 17 cm spacing gave a higher wheat grain yield in both conventional and no tillage systems used. The wheat´s culture can be carried in conventional planting system or no tillage planting, not presenting variation in the grains yield in these cases.
