“…The maximum value of yield (20.53 t ha −1 ) was obtained when the plants were irrigated with the highest IWA (I 100% ), while the minimum value of yield (14.89 t ha −1 ) was recorded for the lowest IWA (I 60% ), (Table 7). Similar trend of results were obtained by (Ertek et al, 2006;Wang et al, 2009;He-xi et al, 2011) who reported that cucumber fruit yields increased with the increase of IWA. This result may be due to the sufficient available water in the soil under this level which led to an increase in both water and nutrients absorption and consequently an increase in the metabolic mechanisms in plants leading to an increase in fruit weight and number of fruit plant −1 .…”

“…Based on reduced tank evaporation, WANG et al (2009) concluded that the treatments of 80 and 100% replacement of water in the soil showed no significant difference in the cucumber yield, implying that application of 80% of the evaporated water in the tank could save 14.3% water irrigation. This reinforces the idea that deficit irrigation can be viable environmentally and technoeconomically, depending on the culture, climate, region, and availability of irrigation water.…”

ABSTRACT:The experiment was performed in the experimental area of the Engineering Department Federal University of Lavras, Minas Gerais State, Brazil. It aimed at identifying the adequate irrigation management of the greenhouse-cultivated Japanese cucumber (Cucumis sativus L.). complete randomized design, with four levels of soil water potential (15; 30; 60 e 120 kPa) at two phenological phases (vegetative and reproductive), and 5 replications. Overall, the results showed decrease of yield according to increase of soil water potentials. During the reproductive stage, Japanese cucumber plants were more sensitive to water deficit, resulting in further decrease in yield compared to applied water deficit during the vegetative stage of the culture. KEYWORDS:Cucumis sativus L., greenhouse, irrigation management. EFEITO DO DÉFICIT HÍDRICO EM DUAS FASES FENOLÓGICAS SOBRE A PRODUÇÃO DO PEPINO-JAPONÊS CULTIVADO EM AMBIENTE PROTEGIDORESUMO: O experimento foi realizado na área experimental do Departamento de Engenharia da Universidade Federal de Lavras, em Lavras -MG, e teve como objetivo identificar um manejo adequado da irrigação para a produção do pepino-japonês (Cucumis sativus L.) cultivado em ambiente protegido. Foi utilizado um delineamento inteiramente casualizado, envolvendo, como tratamentos, quatro níveis de potencial de água no solo (15; 30; 60 e 120 kPa) em duas fases fenológicas da cultura (vegetativa e reprodutiva), com 5 repetições. De forma geral, os resultados mostraram decréscimo da produtividade de acordo com o incremento do potencial de água no solo; as plantas do pepineiro-japonês, quando na fase reprodutiva, mostraram-se mais sensíveis ao déficit hídrico, redundando em maiores quedas de produtividade em comparação com o déficit hídrico aplicado durante a fase vegetativa da cultura. PALAVRAS-CHAVE:Cucumis sativus L., manejo da irrigação, produtividade.

“…There are several methods to reduce soil evaporation. Methods such as the use of drip systems and subsurface drip systems can significantly reduce soil evaporation losses of irrigated land (Wang et al, 2009). In rainfed systems, soil evaporation can be reduced by mechanical mulching (Prathapar and Qureshi, 1999) or by straw mulching (Zhang et al, 2003).…”

Abstract. The paper demonstrates the application of a new water accounting plus (WA+) framework to produce information on depletion of water resources, storage change, and land and water productivity in the Indus basin. It shows how satellite-derived estimates of land use, rainfall, evaporation (E), transpiration (T ), interception (I ) and biomass production can be used in addition to measured basin outflow, for water accounting with WA+. It is demonstrated how the accounting results can be interpreted to identify existing issues and examine solutions for the future. The results for one selected year (2007) showed that total annual water depletion in the basin (501 km 3 ) plus outflows (21 km 3 ) exceeded total precipitation (482 km 3 ). The water storage systems that were effected are groundwater storage (30 km 3 ), surface water storage (9 km 3 ), and glaciers and snow storage (2 km 3 ). Evapotranspiration of rainfall or "landscape ET" was 344 km 3 (69 % of total depletion). "Incremental ET" due to utilized flow was 157 km 3 (31 % of total depletion). Agriculture depleted 297 km 3 , or 59 % of the total depletion, of which 85 % (254 km 3 ) was through irrigated agriculture and the remaining 15 % (44 km 3 ) through rainfed systems. Due to excessive soil evaporation in agricultural areas, half of all water depletion in the basin was non-beneficial. Based on the results of this accounting exercise loss of storage, low beneficial depletion, and low land and water productivity were identified as the main water resources management issues. Future scenarios to address these issues were chosen and their impacts on the Indus Basin water accounts were tested using the new WA+ framework.
