“…According to Duzdemir et al (2009), the pea is a crop which is very sensitive to water stress. Giordano (1997) also highlights that excess of water can affect plant development, due to lodging, an increase of fungal diseases and uneven maturity.…”

Proper irrigation management is crucial to obtain high yields of pea, since its cultivation is recommended in cold and dry seasons. Taking into account the great genetic diversity, we considered necessary to evaluate cultivars which best adapt to the intrinsic conditions of Cerrado Region, as it presents low fertility soil, long dry period in the winter, drought periods (veranicos) in rainy season, mainly in January and February (summer). Thus, the aim of this study was to evaluate adaptability of green-pea cultivars under different irrigation depths in Northeast Region of state of Mato Grosso do Sul. The experiment was installed in a split plot scheme, with four irrigation depths [50, 75, 100 and 125% of crop evapotranspiration (ETc)] and at subplots, four pea cultivars (Forró, Frevo, Pagode and Samba) in a randomized block design with three replications. Pod length, number and mass of grains per pod, number of pods per plant, plant length, productivity and efficiency of water use were evaluated. Excess water supply (water stress) or shortage (water deficit) can cause decrease in the productivity of pea crop for green grains, considering replacement of 114.81% of Etc, the most recommended for the crop. Cultivar Forró, showed the best productive performance in relation to other cultivars, in the climatic conditions of Southern Cerrado (Mato Grosso do Sul, Brazil).

“…Water stress possibly reduced pollen fertility, increased pod abortion and reduced pod filling in soybean that resulted in decreased number of filled pods (Khan et al, 2016;Duzdemir et al, 2009). The maximum 100-seed weight of 10.62 g was obtained from control which was identical to water stress during 4 th to 6 th weeks after emergence (10.52 g) and 6…”

“…Plants are unable to maintain metabolic activities, especially the turgidity of cell for normal growth under salt or water stress conditions, and that finally resulted yield reduction (Khan et al, 2016). Salinity or water shortage decreased pod number in pea (Duzdemir et al, 2009) and soybean (Chowdhury et al, 2015). Soybean is classified as a moderately salt sensitive crop (Katerji et al, 2003) and denoted as sensitive to drought stress, especially at the early reproductive stage (Westgate and Peterson, 1993).…”

“…Prepared saline waters for each treatment were stored in 100 liter-plastic containers. EC i of these waters were controlled by an EC/pH meter (Jenway 430 model) before each irrigation application and the adjustment was done if necessary (Ünlükara et al 2008;Düzdemir et al 2009;Ünlükara et al 2010). Tap water (EC i = 0.65 dS m -1 ) was used to irrigate of the control treatment in the salinity experiment and the treatments of the irrigation regime experiment.…”

“…Letey & Dinar (1986) stated that different conditions for evapotranspiration were obtained by applying different soil moisture regimes but rarely by using saline water. Ozturk et al (2004) reported decreasing effect of salinity on water consumption for lemon balm, Yurtseven et al (2005) for tomato, Ünlükara et al (2008) for okra, Düzdemir et al (2009) for cowpea, Ünlükara et al (2010) for eggplant, Kurunc et al (2011) for bell pepper. Plant water consumption also changes with changing climatic conditions.…”

Both electrical conductivity of soil saturation paste extract (EC e ) and plant water consumption (ET) should be considered for assessing crop yield tolerances to salinity since ET decreases by increased salinity effects. In this study, conducted in a greenhouse under controlled conditions, it was afforded to use soil salinity and water consumption for the purpose of assessing plant responses to salinity. Additionally, growth and yield of green long pepper (Capsicum annuum L. Demre) under different saline and water regime conditions were examined. For these purposes, the green long pepper were exposed to six water salinity levels (S 1 = 0.65; S 2 = 2.0; S 3 = 3.0; S 4 = 4.0; S 5 = 5.0 and S 6 = 7.0 dS m -1 ) and four water application rates (IR 1 = 1.43; IR 2 = 1.0; IR 3 = 0.75 and IR 4 = 0.50 times of depleted water). The yield response factor (K y ), is 1.56 for salinity stress and 1.66 for water stress. Water consumption of the plant exponentially decreased ) whereas relative fruit yield decreased linearly (7.03%) for unit increase in soil salinity after a threshold value of 1.20 dS m -1 . A stronger three-dimensional relation was found among relative yield, relative water consumption and soil salinity (R 2 = 0.94). Using water consumption as a second factor in evaluation of plant response to salinity may be useful for reflecting effects of different climatic conditions.
