The objective of this study was to determine the relationship between body weight (BW) and heart girth (HG) in Sardi and Timahdite sheep in order to develop a prediction equation of BW from HG. The data used for this study included 476 records on BW and HG (227 in Sardi and 249 in Timahdite) collected on males and females of different ages in 33 private farms. The BW and the HG averaged 34.8 ± ...

Abstract Canopy nitrogen content (CNC, kg/ha) provides crucial information for site-specific crop fertilization and the usability of Sentinel-2 (S2) satellite data CNC monitoring at high levels in managed agricultural fields is still underexplored. Winter wheat samples were collected France Belgium 2017 (n = 126) 2018 18), analysed S2-spectra extracted sample locations. A comparison three estab...

Results We present global planting date patterns for maize, spring wheat and winter wheat (our full, publicly available data set contains planting and harvesting dates for 19 major crops). Maize planting in the northern mid-latitudes generally occurs in April and May. Daily average air temperatures are usually c. 12–17 °C at the time of maize planting in these regions, although soil moisture of...

the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...

Although rice paddy fields are one of the world’s largest anthropogenic sources methane CH4, budget ecosystem CH4 and its’ controls in paddies remain unclear. Here, we analyze seasonal dynamics direct ecosystem-scale measurements flux a rice-wheat rotation agroecosystem over 3 consecutive years. Results showed that averaged CO2 uptakes emissions seasons were 2.2 20.9 folds wheat seasons, respec...

Several vegetation indices (VI) derived from handheld spectroradiometer reflectance data in the visible spectral region were tested for modelling grapevine water status estimated by the predawn leaf water potential (Ψpd). The experimental trial was carried out in a vineyard in Douro wine region, Portugal. A statistical approach was used to evaluate which VI and which combination of wavelengths ...

OBJECTIVE Increased basal cortisol levels have been found in bulimia nervosa. After stress, increased cortisol levels have been associated with increased food intake in healthy women. Therefore, we assessed cortisol, hunger, and desire to binge eat after a cold pressor test (CPT) among women with binge eating disorder (BED). METHODS Twenty-two obese (body mass index [BMI] = 36.7 +/- 6.5 SD) f...
