“…Relative water content (RWC) is considered to be a reliable parameter for quantifying plant water status and also is a useful indicator of plant water balance, since it expresses the relative amount of water present on the plant tissues (Farooq and Azam, 2006;Manavalan, et al, 2009 defined that decrease of relative water content close stomata and also after blocking of stomata will reduce photosynthesis rate. Moreover, there are reports about decrease of chlorophyll in these conditions (Saneoka, et al, 2004;Mansouri-far, et al, 2010).…”

“…The limited water resources in these areas and the cost of pumping irrigation water are the most important factors that force many farmers to reduce irrigation in many arid and semi-arid regions (Manavalan, et al, 2009;Mansouri-far, et al, 2010). Evaluation of plant water status plays an important role in assessing plant growth, predicting potential yield and monitoring the general physiological status of vegetation stands (Waraich, et al, 2011).…”

The effects of seed inoculation with Rhizobium and inorganic nitrogen fertilization on some physiological and agronomical traits of chickpea (Cicer arietinum L.) cv. ILC 482, were investigated at the Experimental Farm of the Agriculture Faculty, University of Mohaghegh Ardabili. The trial was laid out in split plot design based on randomized complete block with four replications. Experimental factors were mineral nitrogen fertilizer at four levels (0, 50, 75 and 100 kg urea ha -1 ) in the main plots, and two levels of inoculation with Rhizobium bacteria (with and without inoculation) as sub plots. N application and Rh. inoculation showed positive effects on physiological and agronomical traits of chickpea. The highest value of leaf RWC was recorded at 50 kg urea ha -1 what was statistically in par with 75 kg urea ha -1 application, while the usage of 75 kg urea ha -1 showed the maximum stem RWC. The maximum CMS was obtained from application of 75 kg urea ha ) and Rh. inoculation. Application of 75 kg urea ha -1 was statistically in par with 100 kg urea ha -1 in all of these traits. The results pointed out that some N fertilization (i.e. between 50 and 75 kg urea ha -1 ) as starter can be beneficial to improve growth, development, physiological traits and total yield of inoculated chickpea.

Traditional irrigation which focuses on yield only without considering the availability of water is not an effective method where there is water scarcity. Deficit irrigation (DI) is an alternative irrigation method which saves water without significantly affecting yield. It has been widely used in various crops. There are range limits in every crop in terms of water limit endurance. Through simulation from various research on DI, this limit can be analyzed and the results made available for others who want to apply DI. The simulation was conducted to analyze the limit point in DI treatment.

Deficit irrigation is becoming an important strategy to reduce agricultural water use in arid and semi-arid regions. A field experiment was conducted in 2007 to examine the effect of deficit irrigation on the yield performance of maize crop under Arba Minch (Ethiopia) condition. Based on four phonological growth stages (establishment, vegetative, flowering and grain-filling stages) of maize, the crop was subjected to water deficit during one, two or three growth stages. The highest yield obtained was 5.933 tons/ha and the lowest was 3.467 tons/ha. Treatments that were water stressed during single growth stages such as first and second as well as consecutively during two stages, that is, first and second growth stages produced yields that are not significantly different from the yield achieved under fully irrigated treatment. Compared to the maximum yield, 29 to 42% lower yields were registered under treatments that were subjected to water deficit during three growth stages. Not only frequency of water deficit periods but also its timing was found to have effect on the final yield. Treatments which were stressed during two growth stages had 2.2 (0011) to 38.5% (1010) yield reduction compared to the maximum yield. The highest yield reduction was observed under the treatment which was irrigated only during the fourth growth stage (0001), followed by treatment irrigated during first and third growth stages (1010) and then treatments irrigated only during second stage (0100) . This shows that prolonged deficit over three growing stages will have more yield reduction impacts. Plots stressed during third and fourth growth stages were found to produce lower yields indicating the severe effects of water stress during flowering (tasseling and silking) and early grain-filling stages on yield. The comparison of water savings achieved under different treatments that had no significant differences in yield level from full irrigated plot (1111I) ranged from 18.2% (treatments 0111 and 1011) to 36.4% (0011). This indicates that water deficit during first and second growth stages had no significant effect on the grain yield of corn and it is worthwhile to save irrigation water under this condition. The water use efficiency increased with decreasing water supply and increasing yield level. Irrigation water use efficiency increased with decreasing water supply and related yield which may not be desirable from farmers' perspective.
