“…The model has been successfully used to simulate different cereal UPS in semi-arid areas. We found six papers that discussed planting dates for maize [77,184], barley [136,186], winter wheat [135], and varying nitrogen levels (microdose fertilization) for maize [132]. We found the model to have the potential for extrapolating successful cereal UPS in arid and semi-arid areas.…”

“…It also simulates evapotranspiration as separately soil evaporation and crop transpiration. The model also simulates the biomass accumulated each day using crop specific parameters that are normalized for reference evapotranspiration [183][184][185], which makes the model useful to in different climates [132,186,187]. The model has been successfully used to simulate different cereal UPS in semi-arid areas.…”

Spatiotemporal rainfall variability and low soil fertility are the primary crop production challenges facing poor farmers in semi-arid environments. However, there are few solutions for addressing these challenges. The literature provides several crop upgrading strategies (UPS) for improving crop yields, and biophysical models are used to simulate these strategies. However, the suitability of UPS is limited by systemization of their areas of application and the need to cope with the challenges faced by poor farmers. In this study, we reviewed 187 papers from peer-reviewed journals, conferences and reports that discuss UPS suitable for cereals and biophysical models used to assist in the selection of UPS in semi-arid areas. We found that four UPS were the most suitable, namely tied ridges, microdose fertilization, varying sowing dates, and field scattering. The DSSAT, APSIM and AquaCrop models adequately simulate these UPS. This work provides a systemization of crop UPS and models in semi-arid areas that can be applied by scientists and planners.

“…As lâminas de irrigação proporcionaram efeito linear positivo na matéria seca da parte aérea da cevada BRS Manduri, ou seja, o aumento da lâmina de irrigação proporcionou aumento dessa variável. Araya et al (2010) avaliando a cevada na Etiópia também observaram aumento da biomassa com lâminas crescentes de irrigação. Nas outras cultivares, a lâmina de irrigação proporcionou efeito quadrático (Figura 2).…”

“…O maior valor de eficiência de uso da água, em todos os tratamentos, foi 2,73 kg m -3 , ou seja, para produção de 1.000 kg de grãos de cevada foram necessários 366.000 litros de água. Já as lâminas de irrigação proporcionaram efeito quadrático na eficiência de uso da água pela cevada (Figura 2) corroborando com Guerra (1994), Araya et al (2010) e Mollah e Paul (2011). As máximas eficiências de uso da água pela cevada, estimadas pela equação de regressão, para as cultivares BRS Sampa, BRS Manduri e BRS 195 foram de 2,74; 1,84 e 1,91 kg m -3 , para as lâminas de irrigação de 99,1; 93,4 e 86,5% da ETc, respectivamente.…”

ResumoObjetivou-se avaliar o desempenho agronômico de cultivares de cevada cervejeira submetidas a diferentes lâminas de irrigação no cerrado sul-mato-grossense. O experimento foi conduzido no delineamento inteiramente casualizado, com parcelas subdivididas, tendo nas parcelas quatro lâminas de irrigação (50, 75, 100 e 125% da evapotranspiração da cultura) e nas subparcelas três cultivares de cevada (BRS Sampa, BRS Manduri e BRS 195), com quatro repetições. As cultivares de cevada diferiram apenas em número de perfilhos por planta, espiguetas por espiga e profundidade do sistema radicular. As produtividades máximas de grãos para as cultivares BRS Sampa, BRS Manduri e BRS 195 foram de 5.848, 5.449 e 4.767 kg ha -1 , respectivamente. A cevada BRS Sampa apresentou valor 17% superior à produtividade divulgada pelo detentor. As lâminas de irrigação afetaram todas as características agronômicas avaliadas. Recomenda-se para o nordeste sul-mato-grossense a BRS Sampa irrigada com reposição de 100% da evapotranspiração da cultura, por não ter diferido das demais cultivares e ter sido desenvolvida para região de clima semelhante. Palavras-chave: BRS Sampa, irrigação por gotejamento, Hordeum vulgare L., produtividade AbstractThe research work aimed to evaluate the performance of barley cultivars under different irrigation depths in Brazilian Cerrado. The experiment was conducted in a split plot completely randomized design, with irrigation depths (50, 75, 100 and 125% of crop evapotranspiration) in the plots and barley cultivars (BRS Sampa, BRS Manduri and BRS 195) in the split-plots, with four replications. Barley cultivars were different regarding number of tillers per plant, number of spikelets per spike, and root depth. The maximum yields for BRS Sampa, BRS Manduri and BRS 195 were 5,848; 5,449; and 4,767 kg ha -1 , respectively. BRS Sampa showed a value 17% higher than the yield reported by the holder. The irrigation depth affected all the agronomic traits. It is recommended BRS Sampa for Brazilian Cerrado, that didn't differ from other cultivars and was developed in region of similar climate; with replacement of 100% of crop evapotranspiration.

“…AquaCrop is developed from revision of 'FAO Irrigation and Drainage Paper No. 33 Yield Response to Water' (Doorenbos and Kassam, 1979).The capacity of AquaCrop model in simulating the yield in response to water is proved by various researchers (Araya et al 2010a, Heng et al, 2009Stricevic et al, 2011;Abedinpour et al, 2012, Andarzian et al, 2011.The use of these models can assist in evaluating and reducing time intensive and expensive field tests (Whisler et al, 1986). Model results with regards to crop performance, management and yield estimates will help decision makers to decide which management system is suited best for a particular field, by estimating the yield and crop water productivity optimum.…”
