The olive tree (Olea europaea L.), a species adapted to the Mediterranean climate, has expanded into new climatic regions. Uruguay has a humid temperate climate and highly irregular climatic conditions among years. Environmental factors can be an obstacle to full production, as they affect pollination and fruit set. In this research, the phenology of five olive cultivars (Arbequina, Arbosana, Manzanilla, Picual and Koroneiki) widely cultivated in Uruguay was studied, using the BBCH phenological scale. The pollen grains of five cultivars were submitted to in vitro germination and incubated at temperatures of 0°, 10°, 15°, 20°, 25°, 30° and 40°C for 24 hours, and pollen grains germination and pollen tube length were evaluated. These temperatures were analyzed for the occurrence probability. They were based on the historical series analysis of hourly average temperature data, from September 26 to November 15 (flowering period), for the years of 1998 to 2019. Phenology results show that flowering can occur from day 268 to day 320 of the year, with cultivar 'Manzanilla' being the earliest and 'Arbosana' the latest. It was observed that the temperature of 10°C has no effect on pollen grain germination and on pollen tube growth. Moreover, the temperatures of 15 to
20°C are not very effective and the optimal temperature occurs between 25 and 30°C. In Uruguay, during flowering, temperatures between 10 and 20°C are more likely to occur. These results indicate possible causes that affect fruit set and productivity of olive trees in the field.

Abstract:
Context: Early sown, annual ryegrass pastures and winter crops provide a high-quality feed for livestock and also have a high water content during autumn and early winter compared with typical temperate pastures.
Aim: We hypothesised that beef cattle grazing annual ryegrass or forage oats would not need additional access to drinking water to maintain their intake and growth.
Methods: In Experiment 1, 48 weaned, castrated male Hereford calves with liveweight 154 kg (±6.7 kg; s.d.) grazed Italian ryegrass at a daily allowance of 4.5 kg dry matter (DM)/100 kg liveweight in two treatments including with or without access to drinking water. In Experiment 2, 60 Hereford steers with liveweight 382 kg (±20.6 kg; s.d.) were offered a daily allowance of 5 kg DM/100 kg liveweight of forage oats in a 2 × 2 factorial design either with or without access to drinking water and with or without sorghum grain silage supplemented at 1% of liveweight. The experiments were analysed as a completely randomised design, with individual pasture plots as the experimental unit.
Key results: Daily growth rates of calves in the two treatments were similar (P > 0.05); however, calves with access to drinking water consumed 60% more water than did the calves without drinking water (P < 0.001). Access to drinking water had no effect (P > 0.05) on the daily growth rate of steers (P > 0.05); however, the daily growth rate of supplemented steers was 9% higher than that of the unsupplemented steers (P < 0.05). Total water intake was affected by access to drinking water (P < 0.005) but not access to supplementation (P > 0.05).
Conclusions: Both calves and steers derived no production benefits by having access to drinking water when grazing actively growing annual ryegrass pasture or forage oats. Nevertheless, livestock should be monitored closely so that appropriate interventions can be made if there are changes in the pasture availability or weather.
Implications: Grazing early sown winter forages by livestock can help circumvent the autumn?winter feed gap and these forages can be utilised more cost-effectively by not having to provide drinking water when the DM content is low. MenosAbstract:
