\begin{abstract}
\normalsize{
The water availability for flood irrigated rice is decreasing worldwide. Therefore, developing technologies to allow growing rice in aerobic condition, such as a no"=tillage system (NTS) can contribute to produce upland rice grains without yield losses and also in saving more water. The objective of this study was to determine the effect of soil management, seed treatment and compaction on the sowing furrow on grain yield of upland rice genotypes. We made two trials, one in an NTS and another using conventional tillage, CT (one plowing and two diskings). The field experiments were performed in the Central Region of Brazil in Cerrado soils. For each trial, the experimental design was a randomised block design in a factorial scheme, with three replications. The treatments consisted of a combination of 10 genotypes with 2 compaction pressures on the sowing furrow (25 kPa and 126kPa) and 2 types of seed treatment (with and without pesticide). Under CT, the seed treatment did not contribute to increase upland rice grain yields. However, under NTS the grain yield of some genotypes (BRS Esmeralda, BRS Pepita, AB072044, and AB072085 at 25 kPA soil compaction pressure, and Sertaneja, BRS Pepita, and AB072085, at 126 kPA soil compaction pressure) increased with the use of this practice. At CT the higher soil compaction pressure on the sowing furrow (from 25 kPa to 126 kPa) increased rice grain yield only when it was used seed treatment and the genotypes Serra Dourada, Sertaneja, and Cambará. On the other hand, under NTS, increasing soil compaction pressure on the sowing furrow allowed for an increased rice grain yield of Serra Dourada, Esmeralda, AB072044, and Cambará without seed treatment and Sertaneja  and AB072044 with seed treatment. In CT the most productive genotypes were AB062008 and BRSMG Caravera, while at NTS were the genotypes: BRSGO Serra Dourada, AB072047, AB062008, BRSMG Caravera, Cambará, AB072044, BRS Esmeralda, and BRS Pepita.}
