“…GY, 1000 GW and biomass were also decreased at 70 and 50 % FC. Zain et al (2014) reported that GY, biomass, filled spikelet, 1000 GW and PH were reduced under increased duration of drought stress intervals. Similar results for decline in GY and plant morphology were also reported by Zulkarnain et al (2009).…”

Crop models can provide rapid and cost effective means to deal with rice crop management. The objectives of this study included, exploring the ability of CSM-CERES-Rice in scheduling irrigation and to simulate the effect of drought stress on upland rice yield. Irrigation treatments 100, 70 and 50 % of field capacity (FC) were applied from 80 days after planting (DAP) at flowering stage until maturity and CSM-CERES-Rice was used to predict irrigation amount for each water regime for treatment duration. Results showed that, at 70 and 50 % FC, performance of an upland rice genotype, Dawk Payawm was decreased significantly as compared to 100 % FC. Normalized root mean square error (RMSEn) values less than 10 % for each treatment indicated a strong agreement between simulated and observed grain yield (GY) and biomass. d-index approaching to unity and RMSEn less than 10 % indicated a good agreement between simulated and observed soil moisture contents (SMC) for all irrigation treatments. Overall, it was concluded that drought stress had negative correlation with GY and CSM-CERES-Rice was able to predict irrigation amount for all treatments assuring that, model has potential for its use as a tool to schedule irrigation for experiments under water limited conditions.

“…Zain et al (2014) compararam o desempenho de uma cultivar de arroz própria para o cultivo irrigado por inundação, nos ambientes inundado, saturado e aeróbico com deficit hídrico (sem irrigação por períodos de 5, 10, 15, 20, 25 e 30 dias). Os autores observaram que a produtividade foi a mesma nos tratamentos irrigados por inundação e na condição de solo saturado, mas observaram queda de 15% na produtividade, no cultivo com cinco dias sem irrigação, e superior a 90%, nos cultivos com mais 20 dias de suspenção da irrigação.…”

Resumo -O objetivo deste trabalho foi determinar a influência da tensão de água e de atributos físicos e químicos do solo sobre a produtividade do arroz irrigado por aspersão, em terras baixas no Rio Grande do Sul. Na safra 2011/2012, foram avaliados os efeitos das tensões de água no solo de 20 e 40 kPa, durante todo o ciclo da cultura, bem como as de 40 e 20 kPa nas fases vegetativa e reprodutiva, respectivamente. Na safra 2012/2013, foram avaliadas as tensões de 10, 20 e 40 kPa, durante todo o ciclo da cultura, e as de 40 e 10 kPa nas fases vegetativa e reprodutiva, respectivamente. Em ambas as safras, utilizou-se a cultivar de arroz irrigado BRS Pampa. O gasto com água na irrigação por aspersão representou 48% do gasto com a irrigação por inundação. A produtividade do arroz correlacionou-se positivamente com a microporosidade e com os teores de fósforo e potássio disponíveis no solo; e negativamente com a macroporosidade e a saturação por alumínio. A avaliação conjunta da tensão de água e de atributos físicos e químicos do solo permite avaliar com mais propriedade a variabilidade na produtividade de arroz irrigado por aspersão em terras baixas no Rio Grande do Sul. A irrigação por aspersão possibilita melhor uso da água proveniente da precipitação pluvial, com efeitos positivos sobre a economia de água.Termos para indexação: Oryza sativa, economia de água, fertilidade do solo, física do solo, porosidade do solo, tensão de água no solo. Sprinkler-irrigated rice yield in lowlands as a function of water availability and soil attributesAbstract -The objective of this work was to determine the effect of soil water tension and physicochemical soil attributes on sprinkler-irrigated rice yield in lowlands of the state of Rio Grande do Sul, Brazil. In the 2011/2012 crop season, the effects of 20 and 40 kPa soil water tensions throughout the crop cycle were evaluated, as well as of 40 and 20 kPa during the vegetative and reproductive phases, respectively. In the 2012/2013 crop season, soil water tensions of 10, 20, and 40 kPa were evaluated throughout the entire crop cycle, and the tensions of 40 and 10 kPa were evaluated during the vegetative and reproductive phases, respectively. In both crop seasons, the irrigated rice cultivar BRS Pampa was used. Water costs with sprinkler irrigation represented 48% of that with flood irrigation. Rice yield was positively correlated with soil microporosity and phosphorus and potassium availability; and negatively correlated with macroporosity and aluminum saturation. The joint evaluation of soil water tension and soil physicochemical attributes allow a better evaluation of the variability of sprinkler-irrigated rice yield in the lowland areas of the state of Rio Grande do Sul. Sprinkler irrigation allows better use of rainwater, revealing positive effects on water economy.

“…According to Blum (2009), since biomass production is tightly linked to transpiration, breeding for maximized soil moisture capture for transpiration is the most important target for yield improvement under water deficit. Zain et al (2014) found that 15-day water deficit cycle reduced rice transpiration rate by 42% and, as it has a positive correlation with net photosynthesis rate, reduced grain yield.…”

Performance of low phosphorus tolerant rice genotypes under drought stress

The identification of genotypes more tolerant to water deficit and more efficient in the use of nutrients little available in the soil is an important low-cost strategy to promote sustainable agriculture in marginalized regions. In this sense, a study was carried out in the SITIS Phenotyping Platform of the Embrapa Arroz e Feijão, with the objective of evaluating the drought tolerance of upland rice genotypes tolerant to phosphorus (P) deficiency. The experimental design was performed in a randomized complete block with split-split plots and two replications. In the plots were established two water regimes (with and without water deficit), in the subplots two soil phosphorus contents (25 and 200 mg dm-3) and in sub-subplots 48 upland rice genotypes. The water deficit had more impact on grain yield than the phosphorus supply. The genotypes AB 062037, AB 062041, AB 062138, Arroz Mato Grosso, BRA 02601, BRA 052045, CNA 4098, CNA 6187, Guapa, Guaporé and Rio Paranaíba were classified in the most productive group under both water regimes. The most productive genotypes under water deficit showed higher root density in the deeper soil layers. The most productive genotypes in the two water regimes were also those that showed the highest transpiration.
