“…As many crops are likely to have a plastic root system, this may equally apply to other crops in which alternate partial root-zone drying does not lead to higher yields compared to other water deficient treatments (e.g. Wakrim et al 2005). Moreover, some of the roots in all treatments were episodically exposed to dry soil, which may reduced the effectiveness of the water pattern treatments.…”

“…Specific irrigation technologies have been tested to develop precision agriculture (Kang et al 2000;Panda et al 2003;Wakrim et al 2005), including Alternate Partial Root-zone Drying irrigation (APRD) as a new water-saving irrigation technique (Kang and Zhang 2004;Centritto et al 2005;Liu et al 2006). Previous studies on APRD showed that it provides a means of reducing water consumption while minimizing adverse effects on yield (Sepaskhah et al 1997;Kang et al 2000;Kirda et al 2004).…”

Root foraging and yield components underlying limited effects of Partial Root-zone Drying on oilseed rape, a crop with an indeterminate growth habit

We report on two experiments with oilseed rape (Brassica napus L.) to test if partial root-zone drying techniques improve yield in a crop in which vegetative and reproductive growth overlap (indeterminate growth habit), and to investigate what plant morphological responses contribute to the yield that is realized. Deficit irrigation resulted in smaller plants with smaller yields but larger seeds compared to treatments with shallow groundwater (first experiment) and with fully watered conditions (second experiment). Different partial root-zone drying treatments (water supply patterns) under deficit irrigation, however, had little effect on plant growth and yield components (number of branches, branch lengths, number of pods, etc.). Our results suggest that partial root-zone drying doesn't work well with oilseed rape. Detailed measurements of soil water contents and root distribution indicate that roots were extremely plastic, effectively foraging for water, and these root responses may have overwhelmed physiological effects of partial root drying on the shoot. Furthermore, in crops with indeterminate growth with a short vegetative growth phase, partial root-zone drying may be ineffective in enhancing the major yield components. Further reasons for the lack of success are discussed.

“…Mixed cropping, rainwater harvesting, or no-tillage agriculture were among the more commonly applied strategies to combat drought in dry environment (Davies et al, 2011). Since biomass production was tightly linked to transpiration (Blum, 2009), reduced yield might occur with DI or PRD (Wakrim et al, 2005), although increased water productivity and yield were observed in many other cases (Sadras, 2009;Sepaskhah and Ahmadi, 2010). The ability of soybean to increase their water-use efficiency (WUE) with partial closure of stomata (Liu et al 2005) could be responsible for their relative production resilience (Fig.…”

As a result of climate change, drought is predicted to pose greater pressure on food production system than in the past. At the same time, crop yield co-varies with both environmental (e.g., water, temperature, aridity) and agronomic variables (i.e., crop species, soil texture, phenological phase).To improve our quantitative understanding on the effect of these co-varying factors on agricultural productivity, we synthesized previous meta-analysis studies summarizing the results of numerous independent field experiments on drought and its effect on the production of cereal, legume, root and/or tuber (root/tuber) crops. We also included new crops species that were not covered in previous meta-analyses and the effects of heat stress. Our results indicated that cereals tended to be more drought resistant than legumes and root/tubers. Most crops were more sensitive to drought during their reproductive (i.e., grains filling, tuber initiation) than during their vegetative phase, except for wheat, which was also sensitive during vegetative phase. Recovery from drought impact at reproductive phase was either: (i) unfeasible for crops experiencing damage to their reproductive organs (e.g., maize, rice) or (ii) limited for root/tuber crops, provided that water was abundant during the subsequent root/tuber bulking period. Across soil texture, the variability of yield reduction for cereals was also lower in comparison to legume or root/tuber crops, probably due to the extensive and deep rooting system of cereal crops. As crop species, plant phenology, and soil texture were important co-varying factors in determining drought-induced crop yield reduction, no single approach would be sufficient to improve crop performance during drought. Consequently, a combination of approaches, particularly site-specific management practices that consider soil conditions (i.e., intercropping, mulching, and crop rotation) and selection of crop varieties adjusted to the local climate should be adopted in order to improve the sustainability of agricultural production in a changing climate.3

“…Sob condições de sequeiro, conhecer o período de cultivo mais propício é essencial quando se tenta evitar que a cultura tenha resposta negativa ao estresse hídrico. Wakrim et al (2005) observaram uma diminuição do desempenho da cultura conforme havia menor disponibilidade de água, mas ao mesmo tempo a eficiência do uso da água apresentava aumento. Tendo em vista que o sistema radicular das plantas que vão estar sobre déficit hídrico, vai estar mais desenvolvido em profundidade devido à procura de água no solo, a cultura estará aproveitando melhor a disponibilidade de água que encontra ao longo do perfil.…”

RESUMOO cultivo de feijão é tradicional ao produtor brasileiro, principalmente para os pequenos e médios produtores. No plantio, as altas produtividades se devem em parte à irrigação, que para ser feita de maneira sustentável tem que ser acompanhada de um manejo. Objetivou-se estudar nesse trabalho o comportamento da cultivar de feijoeiro "Ouro Vermelho" a vários níveis de irrigação durante o período sem ocorrência de chuva frequente. Foram testados quatro níveis de irrigação de acordo com uma metodologia de cálculo de lâmina utilizada para o manejo de irrigação, variando em 30%, 80%, 100% e 145% da quantidade recomendada por este método. A irrigação foi feita através de um pivô central convencional. A área experimental era plana, uniforme e não apresentava problemas de salinidade do solo e da água, e ocorrência de ataque de doenças ao longo do experimento. A ausência do ajuste quadrático em relação às lâminas de irrigação não permitiu a definição de um ponto ótimo para a produção final de grãos e biomassa, sendo quanto maior a lâmina maior o desempenho da cultura. O índice de aproveitamento da água evapotranspirada pela planta foi proporcional à sua produtividade nos níveis de lâmina aplicados. Conclui-se que as lâminas de irrigação apresentaram efeito crescente no rendimento da cultura no campo.Palavras-chave: agricultura irrigada, produção agrícola, disponibilidade hídrica.
