ABSTRACT.- Yield and fruit quality are two of the most important parameters for the profitability of vegetable crops. In commercial vegetable production, nitrogen (N) is commonly applied in excess, which is associated with nitrate (NO3−) leaching loss. In addition, excess N application may affect yield and fruit quality. The aim of this study was to evaluate the effect of N applications of very deficient N (N1, 2 mmol L−1), deficient N (N2, 8 mmol L−1), and conventional N (N3, 14 mmol L−1), according to local fertigation practices, in soil-grown muskmelon and sweet pepper crops in Almeria, South-Eastern Spain. The evaluation was conducted in three cultivars of each species. The yield and the fruit quality parameters of firmness, colour, total soluble solids (TSS) and morphometric variables were evaluated in two years for each species. For most parameters in both species, the effects of N, when significant, occurred regardless of cultivar. In muskmelon and sweet pepper, application of 8.2 mmol N L−1 (i.e., N2) was sufficient to achieve a maximum yield of 6.7 and 7.4 kg m−2, respectively. In muskmelon, very deficient N application led to an increase of 58% in the percentage of fruit discarded, mostly due to malformed and undersized fruits. Fruit firmness and red?green axis coordinate (a*) were not consistently affected by N in any of the crops. However, the fruit lightness (L*) increased with N addition in both species, likely because of increased chlorophyll pigments. With N addition, fruit TSS slightly decreased in muskmelon and slightly increased in sweet pepper. However, fruit TSS of both species were within reference values for commercialisation in the three N treatments. There were differences in yield between cultivars in muskmelon but not in sweet pepper, likely due to differences in fruit number in muskmelon. There were differences between cultivars in TSS and colour a* coordinate in both muskmelon and sweet pepper. Cultivars with higher TSS and a* coordinate will likely be more desirable for consumers because of the sweeter taste and more intense orange colour in muskmelon and reddish colour in sweet pepper. Overall, our manuscript showed that N application can be reduced, relative to the conventional N application, without reducing yield or fruit quality in muskmelon, yet additional studies should be conducted in sweet pepper to complement the results of the 2020 crop.

Abstract:
Context: Environmental conditions during hot weather decrease feed intake and cattle growth.
Aims: This study conducted over three consecutive years, during the summer, evaluated access to shade as a strategy to mitigate heat stress of finishing cattle in Uruguay.
Methods: Each year, 32 Bos taurus and/or Bos taurus crossbred steers (initially weighing 461 ± 28 kg) were blocked by initial liveweight and assigned to one of eight pens, where one of two treatments were applied, namely, no shade access or shade access (mean shaded area 4.5 m2/animal). Finishing diet was offered three times per day and cattle had ad libitum access to water. Twenty-four pens were considered in a randomised complete-block design. Average daily gain (ADG), dry matter intake (DMI) and feed efficiency were measured, and hot carcass weight was collected at slaughter. Ruminal pH and temperature were obtained using ruminal boluses. Feeding, drinking, rumination, inactive behaviours, respiration rate and painting score were observed.
Key results: Mean days on feed were 70.6 ± 5.5. The average THI ranged from 70 to 72. Steers with access to shade had greater DMI (P = 0.003), ADG (P = 0.004), and feed:gain ratio (P = 0.05) than did not shaded steers. Ruminal pH was higher (P < 0.0001) in shaded than in not shaded animals. The slaughter weight of shaded steers was 10 kg greater (P = 0.02) than that of not shaded steers. A trend (P = 0.06) to higher hot carcass weight after dressing was obtained by shaded steers. The average respiration rate and panting score was consistently lower (P < 0.0001) for shaded than for not shaded steers, except in the early morning. Access to shade increased the time spent by animals feeding (P = 0.008) and ruminating (P = 0.001), decreasing inactive time (P < 0.0001).
Conclusions: Shade could improve performance and welfare of feedlot cattle during summertime, even in regions with an average THI from 70 to 72.
Implications: Access to shade allowed fattening cattle to dissipate heat stored during the day at night and to alleviate the effect of heat load during summer in subtropical region. MenosAbstract:
