“…Similar effect was observed on grain yield of wheat genotypes that was decreased 30% and 42% over canal water treatment in SARC-1 and V-8670, with application of brackish tubewell water. These findings are correlated with ealier studies of Hamdy et al (2005) observed that saline water (9 dSm -1 ) decreased wheat grain yield upto 25% when compared with canal water treatment. The variation in the behavior of wheat genotypes indicated that SARC-1 produced better yield as compared to V-8670 under all treatments.…”

A field experiment was conducted to study the effect of brackish water on soil physical and chemical conditions and yield of wheat and maize genotypes at the farmers' field. Two salt tolerant genotypes for each crop were selected from previous hydroponic and lysimeters studies. Wheat-maize cropping system was followed using tubewell brackish water alone and with chemical (gypsum) and organic (FYM) amendments. The results revealed that treatments have significant effect on all growth and yield parameters and followed the trend of T1>T3 >T4 > T2. Highest grain yield of wheat genotypes (SARC

“…Moreover, tomato growth and yield were higher in alternate practice only with fresh water, whereas moderate saline irrigation for mixed treatment had the highest yield and growth. Hamdy et al (2005) investigated the possibility of saline supplemental irrigation for rainfed wheat and barley during their sensitive stages of flowering and seed formation in a Mediterranean climate. In both cases, their results showed that crop yield increased under limited irrigation of brackish water.…”

“…It seems that four days irrigation frequency in this study and daily irrigation in Tscheschke's study was the reason for this different result. However, Yazar et al (2003) stated that soil salinity increases with increasing of irrigation water salinity and salt distribution profile under saline irriga- 10 naturally play a very important role in salts leaching and justify the use of saline water for some treatments. This is true when the soil is well drained and salts can move below the root zone or out of the soil profile.…”

Use of saline water for irrigation is a strategy to mitigate water shortage. The objective of this study was to investigate the impact of the cyclic and constant use of saline and non-saline water on drip irrigated maize yield and irrigation water use efficiency (IWUE). Nine field treatments were laid out based on alternative irrigation management of non-saline and saline water combinations. The treatments were: two salinity levels of 3.5 and 5.7 dS/m and freshwater (0.4 dS/m) application in every one, three and five saline water application (1:1, 3:1 and 5:1, respectively). Results showed that the 1:1 combination management was the best in terms of crop yield and IWUE. In this treatment, salt concentration at the end of growing season was not significantly changed compared to its initial condition. If off-season precipitation or leaching was available, the 3:1 and 5:1 treatments were appropriated. Highest and lowest values of IWUE were 15.3 and 8.7 kg/m3 for the 1:1 management using water salinity of 3.5 dS/m and the treatment of constant irrigation with water salinity of 5.7 dS/m, respectively. Under low off-season precipitations, artificial leaching is essential for land sustainability in most treatments.

“…Apesar dos inconvenientes relacionados ao uso de água com qualidade inferior, algumas estratégias podem ser utilizadas para minimizar os impactos negativos do seu aproveitamento na irrigação, entre elas: escolha de espécies ou cultivares mais tolerantes, utilização dessas fontes de água nos estádios de maior tolerância das culturas, mistura de águas de diferentes qualidades, uso cíclico de fontes de água com diferentes concentrações salinas, além de diversas outras práticas (LACERDA et al, 2009). Pesquisas recentes enfocaram o manejo diferenciado da irrigação com água salina em diversas culturas (BOTÍA et al, 2005;CHAUHAN;SINGH;GUPTA, 2008;HAMDY;SARDO;FARRAG GHANEM, 2005;LACERDA et al, 2009;MALASH;FLOWERS;RAGAB, 2005;MORAIS et al, 2011;MURTAZA;GHAFOOR;QADIR, 2006). Outros estudos foram realizados para avaliar a influência da irrigação com água salina na mamoneira e vários deles indicaram suscetibilidade dessa espécie (CAVALCANTI et al, 2005;PINHEIRO et al, 2008;S I LVA et al, 2005S I LVA et al, e 2008.…”

RESUMO -Este experimento foi realizado em campo para avaliar estratégias de irrigação com água salina no crescimento e na produção da mamoneira (BRS Energia), além de identificar eventuais estádios de maior tolerância à salinidade e monitorar alguns atributos químicos do solo. Os tratamentos consistiram da irrigação com águas de CE 0,53; 2,09; 3,66 dS m -1 de acordo com a fase de desenvolvimento da cultura, totalizando cinco estratégias de irrigação com água salina e uma testemunha. As avaliações de crescimento foram realizadas aos 20; 40; 60; 80; 100 dias após a semeadura (DAS). As coletas de solo foram realizadas concomitantemente às avaliações de crescimento, nas camadas 0-0,10; 0,10-0,30; 0,30-0,50 m. A irrigação contínua com água de CE 3,66 dS m -1 reduziu a altura de planta, o comprimento de racemo terciário, o número de frutos por área útil e a produtividade de frutos. Essa estratégia aumentou acentuadamente os teores de Na + e a CE do solo no final do ciclo. Por outro lado, a irrigação com água salina começando aos 45 DAS não prejudicou as variáveis de crescimento e os componentes de produção. Essa estratégia minimizou os impactos negativos sobre a salinidade/sodicidade do solo no final do ciclo. Comportamento similar foi observado para a irrigação contínua com água de CE 2,09 dS m -1 (mistura de águas com CE de 0,53 e 3,66 dS m -1 ). A mamoneira não apresentou tolerância diferenciada à salinidade em função da fase de desenvolvimento, embora tenha sido prejudicada quando aumentaram a intensidade e a duração do estresse salino.

BRS Energia), identify eventual stages with higher tolerance to salinity and monitor some soil chemical attributes. The treatments consisted of irrigations with water of EC 0.53; 2.09; 3.66 dS m -1 according to the development stage of the culture, totalizing five irrigation strategies with saline water and a control group. The growth evaluations were done at 20; 40; 60; 80; 100 days after sowing. The soil samples were taken at the same time of the growth evaluations, from the layers of 0 to 0.10; 0.10 to 0.30; 0.30 to 0.50 m. Continuous irrigation using water with EC of 3.66 dS m -1 reduced the plant height, length of tertiary raceme, number of fruits per area and fruit yield. This strategy increased the values of soil chemical attributes Na + and EC at the end of cycle. From the 45th day on, irrigation with saline water did not damage the growth variables and the production components. This strategy minimized the negative impacts on the salinity/sodicity of the soil at the end of cycle. Similar behavior was observed for continuous irrigation using water with EC of 2.09 dS m -1 (mixing of water with EC of 0.53 and 3.66 dS m -1 ). The castor oil plant did not show different tolerance to salinity according to ...
