The application of remote sensing in plant breeding is becoming a routine method for fast and non-destructive high-throughput phenotyping (HTP) using unmanned aerial vehicles (UAVs) equipped with sensors. Alfalfa (Medicago sativa L.) is a perennial forage legume grown in more than 30 million hectares worldwide. Breeding alfalfa for herbage accumulation (HA) requires frequent and multiple phenotyping efforts, which is laborious and costly. The objective of this study was to assess the efficiency of UAV-based imagery and spatial analysis in the selection of alfalfa for HA. The alfalfa breeding population was composed of 145 full-sib and 34 half-sib families, and the experimental design was a row-column with augmented representation of controls. The experiment was established in November 2017, and HA was harvested four times between August 2018 and January 2019. A UAV equipped with a multispectral camera was used for HTP before each harvest. Four vegetation indices (VIs) were calculated from the UAVbased images: NDVI, NDRE, GNDVI, and GRVI. All VIs showed a high correlation with HA, and VIs predicted HA with moderate accuracy. HA and NDVI were used for further analyses to calculate the genetic parameters using linear mixed models. The spatial analysis had a significant effect in both dimensions (rows and columns) for HA and NDVI, resulting in improvements in the estimation of genetic parameters. Univariate models for NDVI and HA, and bivariate models, were fit to predict family performance for scenarios with various levels of HA data (simulated in silico by assigning missing values to full dataset). The bivariate models provided higher correlation among predicted values, higher coincidence for selection, and higher genetic gain even for scenarios with only 30% of HA data. Hence, HTP is a reliable and efficient method to aid alfalfa phenotyping to improve HA. Additionally, the use of spatial analysis can also improve the accuracy of selection in breeding trials.

High Wide Ridge Soil Management is a conservation practice associated with the no-tillage, reduced tillage, and conventional tillage systems, usual in small farms in southern Brazil. Integrated with winter grain or ground cover crops such as wheat (Triticum aestivum), rye (Secale cereale), black oats (Avena strigosa) and white oats (Avena sativa), millet (Pennisetum glaucum L.), Sudan grass (Sorghum sudanense), sorghum (Sorghum spp.), mucuna (Mucuna spp.), and brachiaria (Brachiaria spp.), high wide ridge is being used for tobacco (Nicotiana tabacum), soybean (Glycine max L.), maize (Zea mays), and beans (Phaseolus vulgaris) during the spring and summer seasons. The benefits expected from this technology, related to the performance of the tobacco crop, have already been proven experimentally and on a farm scale. However, the benefit in regard to the effectiveness in controlling runoff resulting from intense rainfall, has not yet been quantified. The aim of this study was to validate the effectiveness of the high wide ridge in containing runoff from intense rainfall, with return periods equal to, or greater than, 10 years. The study was carried out on 11 farms, located in nine municipalities (four in Rio Grande do Sul state, three in Santa Catarina state, and four in Paraná state), where tobacco was grown following winter cereal as a ground cover crop, on three types of topography (gently undulating topography, undulating topography, and highly undulating topography) with 11 soil types that were texturally and taxonomically different. It was concluded that high wide ridge is capable of containing the flooding generated by rainfall with return periods of more than 10 years, allowing the science of soil conservation to promote it as a conservation soil management practice.
