Abstract

This was aimed to evaluate the effects of plant arrangements and cutting systems on the yield and quality of dual purpose wheat. The present study was conducted in the years 2015, 2016 and 2017 in Frederico Westphalen, belonging to the state of Rio Grande do Sul. The dual purpose wheat genotype used was BRS Tarumã. For this, five sowing densities were used, namely: 75, 150, 225, 300 and 375 seeds per square meter. The analysis of variance revealed significance for the interaction sowing density x cutting systems x chemical quality for the variables dry matter per hectare, lipids, digestible fiber in acid detergent, lignin, cellulose, mineral matter, total carbohydrates and non-fibrous carbohydrates. The positive effects on yield and bromatological quality of the forage are obtained by arranging plants and cutting systems through the sowing density of 300 to 375 seeds per meter with the practice of up to two cuts in dual purpose wheat. Superior dry matter per unit area was observed in the second cut, which was defined by the stimulation of tillering, regrowth and split nitrogen fertilization. Since, the superior bromatological quality is determined by the magnitude of non-fibrous carbohydrates in the forage.

Highlights

Wheat (Triticum aestivum L.) is considered an annual cycle plant, of great economic importance among winter crops (Mendes et al, 2015), ranked as the second most produced cereal in the world for the purpose of foraging and obtaining flour (Zocche, et al, 2018)
An increment in agricultural production is necessary, at the same time as the preservation of natural resources and biodiversity must be taken into account (Trewavas, 2002)

Summary

Introduction

Wheat (Triticum aestivum L.) is considered an annual cycle plant, of great economic importance among winter crops (Mendes et al, 2015), ranked as the second most produced cereal in the world for the purpose of foraging and obtaining flour (Zocche, et al, 2018). Wheat is an important component in crop succession and rotation systems, maximizing the potential to generate wealth per soil area in the winter period (Mendes, et al, 2018). An increment in agricultural production is necessary, at the same time as the preservation of natural resources and biodiversity must be taken into account (Trewavas, 2002). In this agenda, crop-livestock integration emerges, which are based on the premise of the sustainability of production systems (Santos et al, 2011). The advancement of research in genetic improvement and in the management of the crop has enabled genotypes of dual purpose to be obtained, so is grain production aimed, and the ability to provide quality fodder to animals (Bartmeyer et al, 2011; Carvalho, 2016a)
