1. Pre-harvest desiccation in biomass sorghum with herbicides
ABSTRACT The purpose of this study was to assess the effect of different herbicide treatments on moisture removal and calorific power of biomass sorghum for co-generation of electric energy through burning. The experiment was conducted in randomized complete block design with four replicates per treatment and a 6x4 factorial scheme (six herbicide treatments

2. Response to commentary by Howard Waitzkin
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

5. Quantitative and qualitative damages of Oebalus poecilus on irrigated rice in southern Brazil
ABSTRACT Oebalus poecilus is one of the most important pests of irrigated rice in Brazil. However, the impact of this species on the cultivar IRGA 424 RI, which is the most used, is unknown. Hence, the objective of this work is to evaluate the damage caused by O. poecilus on cv IRGA 424 RI. Panicles of this cultivar were infested for seven days at the R5 sta

6. Biomass and nitrogen accumulation in white oat (Avena sativa L.) under water deficit
ABSTRACT Knowledge on nitrogen absorption rate by crops can indicate important managements, especially the definition of rates of this nutrient and the best time for topdressing application. This study aimed to evaluate and compare the accumulation of biomass and nitrogen in white oat cultivated under severe, moderate and no water deficit. Treatments consist

7. Agronomic performance of white oats cultivated under fertigation with treated sewage effluent and definition of critical limits of Normalized Difference Vegetation Index
ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.

8. Phenotypic variance of black oat growing in crop seasons reveals genetic effects predominance
Abstract: This work aimed to determine variance components and genetic parameters, as well as phenotypic, genetic and environmental correlations among black oat (Avena strigosa) families grown in different crop season. Seventy-six black oat families and three controls (BRS Madrugada, BRS Centauro, BRS 139 Neblina) were evaluated in two crop seasons (2016 and

11. Estimates of genetic parameters between and within black oat populations
ABSTRACT The aims of this study were to characterize black oat populations by estimating between- and within-populations variance components and genetic parameters, as well as to distinguish the populations using multivariable statistics. The experiment was carried out in randomized blocks design with three repetitions, with 14 black oat populations collecte
