“…The dry matter production of grains (Figure 3) decreased due to the increasing of the concentration of salts in irrigation water. The action of these salts can go beyond a simple decrease in soil water potential to cellular injury caused by oxidative stress in plants (GARCIA et al, 2007b), and these effects together result in reduced productivity (FERREIRA et al, 2007;AGUIAR NETO et al, 2008;BLANCO et al, 2008). The yields obtained were 4,362, 4,366, 3,606 and 3,110 kg ha -1 respectively for T1, T2, T3 and T4.…”

ABSTRACT:The use of saline water and the reuse of drainage water for irrigation depend on longterm strategies that ensure the sustainability of socio-economic and environmental impacts of agricultural systems. In this study, it was evaluated the effects of irrigation with saline water in the dry season and fresh water in the rainy season on the soil salt accumulation yield of maize and cowpea, in a crop rotation system. The experiment was conducted in the field, using a randomized complete block design, with five replications. The first crop was installed during the dry season of 2007, with maize irrigated with water of different salinities (0.8, 2.2, 3.6 and 5.0 dS m -1 ). The maize plants were harvested at 90 days after sowing (DAS), and vegetative growth, dry mass of 1000 seeds and grain yield were evaluated. The same plots were utilized for the cultivation of cowpea, during the rainy season of 2008. At the end of the crop, cycle plants of this species were harvested, being evaluated the vegetative growth and plant yield. Soil samples were collected before and after maize and cowpea cultivation. The salinity of irrigation water above 2.2 dS m -1 reduced the yield of maize during the dry season. The high total rainfall during the rainy season resulted in leaching of salts accumulated during cultivation in the dry season, and eliminated the possible negative effects of salinity on cowpea plants. However, this crop showed atypical behavior with a significant proportion of vegetative mass and low pod production, which reduced the efficiency of this strategy of crop rotation under the conditions of this study.

SALINIZAÇÃO DO SOLO E PRODUTIVIDADE DE MILHO E FEIJÃO CAUPI EM SISTEMA DE ROTAÇÃO CULTURAL UTILIZANDO ÁGUAS SALINASRESUMO: A utilização de águas salinas bem como o reúso de águas de drenagem na irrigação dependem de estratégias de longo prazo que garantam a sustentabilidade socioeconômica e ambiental dos sistemas agrícolas. Neste trabalho, avaliaram-se os efeitos da irrigação com água salina na estação seca e com água de baixa salinidade na estação chuvosa sobre o acúmulo de sais no solo e a produtividade de milho e feijão-de-corda em sistema de rotação. O experimento foi conduzido em campo, utilizando-se do delineamento em blocos ao acaso, com cinco repetições. O primeiro cultivo foi instalado durante a estação seca de 2007, com a cultura do milho irrigada com água de diferentes salinidades (0,8; 2,2; 3,6 e 5,0 dS m -1 ). As plantas foram coletadas aos 90 dias após a semeadura (DAS), sendo realizadas as avaliações: crescimento vegetativo, produção de grãos por planta, matéria seca de 1.000 grãos e produtividade. Durante a estação chuvosa de 2008, foi cultivado o feijão caupi nas mesmas parcelas que foram cultivadas com milho. Ao final do ciclo, as plantas foram coletadas, sendo realizadas avaliações de crescimento vegetativo e produtividade. Amostras de solo foram coletadas antes e após o cultivo do milho e ao final do cultivo com feijão caupi....

“…Salinity affects the dry and fresh mass (Tabatabaei 2006;Blanco et al 2008;Demir and Mazi 2008) the development and the productivity of cultivated species (Neto and Nogueira 1999;Kaya et al 2007;Zheng et al 2008;Demiral 2009, Galvan-Ampudia andTesterink 2011). Reduction in the growth rate of the leaf can represent an adaptation to salt stress, since increased levels of salts in the soil impedes the uptake of water by the plant (Carillo et al 2005) and the reduction in leaf area limits transpiration (Neumann 1997).…”

“…For fertigation purposes, the electrical conductivity (EC) can be expressed by the soil solution electrical conductivity (ECs) in unsaturated conditions, and by the saturation extract electric conductivity (ECse), i.e., EC saturated soil solution. Electrical conductivity values at certain levels may cause decreased productivity (BLANCO et al 2008). …”

ABSTRACT:The aim of this study was to evaluate the effect of calcium nitrate concentration of irrigation water on soil chemical attributes and productivity during the first 'Terra' banana crop cycle. The experiment followed a completely randomized design with six treatments and five replications, with six plants per plot. Treatments consisted in the use of three calcium nitrate concentrations (3.0, 10.0 and 13.0 g.L -1 ), applied via dripping and micro-micro-sprinkling irrigation. The results showed that the soil chemical properties under fertigation are influenced by the water and nutrient delivery system. There was a linear tendency of increase in electrical conductivity of the saturation extract and soil solution with the increase in calcium nitrate concentration in irrigation water. The banana tree productivity was influenced by the fertilizer concentration in irrigation water.
