Legume overseeding along with P fertilization is a common practice used in natural temperate and subtropical grasslands to increase forage production. This practice has been evaluated at experimental plots but not at the paddocks level of commercial farms. The latter are realistic evaluation units to generate knowledge for livestock management. In this study, the enhanced vegetation index (EVI), a proxy of forage production, was used to evaluate the effect of this practice on grazed paddocks in Uruguay. Twenty paired paddocks under similar grazing conditions were selected with natural grassland (NG) and natural grassland with legume overseeding and P fertilization (NG-LP). Paired paddocks were compared in terms of EVI mean and its temporal variability. After nine years of the intensification practice, mean annual EVI of NG-LP was 4% higher than that of NG, while the mean winter?spring EVI of NG-LP was 7.5% higher. EVI intra- and inter-annual variability of NG-LP was 8?11% higher than that of NG. Additionally, forage production was estimated using a radiative transfer model. Differences between NG-LP and NG were amplified six to seven times. Legume overseeding along with P fertilization increased forage production in pastoral livestock paddocks, particularly in the period of forage deficit, while it also increased intra and inter-annual variability of forage production. |

ABSTRACT.- Apple trees set many more fruit than desired, requiring a crop load adjustment to achieve acceptable fruit size in the season and an adequate return bloom, thus avoiding biennial bearing. Thus, the aim of this study was to evaluate the effect of different plant growth regulators as 6-benzyladenine (6-BA) and naphthaleneacetic acid (NAA) sprays and lime sulfur (LS) in apple thinning. Two trials were carried out in Uruguay on 2020/2021 growing season in 'Gala Baigent' and 'Rosy Glow' apples, respectively. Productive and quality parameters were evaluated. LS (3%) sprayed three times near the bloom and the different combination of 6-BA (100 mg L-1) + NAA (10 mg L-1) showed positive results reducing the number of thinned fruit and time of hand thinning compared to control trees in 'Gala Baigent' in 2020/2021 growing season. LS (3%) and the combination of 6-BA + NAA increased fruit weight of 'Gala Baigent' and did not significantly reduce yield on 2020/2021 growing season. For 'Rosy Glow' apples, LS sprayed three times reduced the number of thinned fruit and time of hand thinning compared to control. Fruit weight of 'Rosy Glow' apples was not increased by LS neither NAA at full bloom + 6-BA at petal fall, however, the combination of 6-BA (100 mg L-1) + NAA (10 mg L-1) at petal fall and the multiple sprays of NAA at full bloom plus the combination of 6-BA and NAA at petal fall, plus 6-BA + mineral oil at 15-18 mm increased fruit weight compared to untreated control trees. Collectively, our results are promising and indicate all the thinners used are potential tools on a chemical thinning program for apples to replace carbaryl. Furthermore, LS could be an option for growers in a thinning program, including for organic production. © 2023 International Society for Horticultural Science. All rights reserved.
