| The objective of this study was to evaluate the operating performance of crop residue cutting discs with distinct cutting edges in the no-tillage system, in relation to the travel speed of the tractor/tool holder set. The experiment was carried out in an experimental area, the soil classified as Paleudalf. The experiment consisted in a factorial arrangement of 4x4, totaling 16 combinations of treatments and three replications, composed by the interaction of the factors: crop residue cutting discs (plain flat disc, wavy disc, rippled disc, and helical wavy disc coulter) and travel speed (1.11; 1.67; 2.22 and 2.78 m s-1). It was used a mobile tool holder structure for the coupling of the active organs, which was pulled by a farm tractor. For the collection... |

| ABSTRACT: The mysterious ancient Mesoamerican Indian crop chia (Salvia hispanica) is revived and expanding worldwide due to its richness of valuable nutraceuticals such as α-linolenic acid (ALA), antioxidants, food fiber, gels, and proteins. We carried out a pilot experiment on chia planting in non-frost Sichuan Basin, at Hechuan Base (30˚0′ 43″ N, 106˚7′ 41″ E, 216 m), Southwest University, Chongqing, China. The split-plot trial contained two factors, 3 spring-summer sowing times as main plots, and 6 densities as subplots, with 3 replicates. Phenological, botanical, adversity, yield, and seed quality traits were investigated. Plants were very tall, suffered from lodging, and flowered in mid-October. Sichuan Basin can be considered as a north edge for... |
