“…This was also pointed out more recently by Reddy et al (2003) in a review. The flowering rate was shown to depend on the frequency of water application and was reduced when water was applied less than once in 6 d (Ishag, 1982). Peg elongation depends on turgor and was shown to be delayed by drought (Boote and Ketring, 1990).…”

ture in the pod elongation zone is critical for peg penetration and the formation of pods (Reddy et al., 2003). Irrigation of peanut (Arachis hypogaea L.) with a moving sprinklerDevelopment of pods and kernels is progressively inhibirrigation system (MSIS) could affect runoff, evaporation, and crop yield. The objective was to determine the effects of irrigation manage-ited by drought because of lack of turgor and insuffiment on soil water withdrawal, runoff, peanut yield and quality, and cient assimilates (Boote and Ketring, 1990; Meisner and irrigation water use efficiency (WUE). Peanut was grown in a com- Karnok, 1992). Other researchers (e.g., Pallas et al., 1979; mercial field on a loess soil that is sensitive to seal formation and Metochis, 1993), however, claim that proper soil moisrunoff. Irrigations were applied once every 3 or 7 d during the vegetature during the entire growing period is important for tive stage, and each of these treatments was subdivided into three optimal production. In semiarid regions, optimal soil irrigation-frequency treatments of 3, 7, and 10 d during the flowering moisture content can be maintained by proper irrigaand pod-filling stages.

“…Water relations of groundnuts, and their irrigation and water use in the United States, have been comprehensively reviewed by Klepper (1973) and Davidson et al (1973). Water stress reduces yield (Ishag, 1982) and produces pods with a greater aflatoxin content (Pettit et al, 1971).…”

S U M M A R YA field study was conducted on vertisols to determine the effect of three watering regimes and two plant densities on growth and yield of groundnuts. Total water requirements ranged from 486 to 597 mm depending on treatments. Three quarters of the water depletion was from the upper 20-30 cm. Plants in the sparse population were more sensitive to water stress so that the watering interval could be lengthened in the dense population without seriously reducing yield.

“…Previous studies indicated that the phenological stages of peanut that are most sensitive to drought stress are the flowering and pod filling stages (Black et al 1985;Stirling et al 1989;Reddy et al 2003). Ishag (1982) found that irrigation frequency affected the flowering rate, such that less than once irrigation every 6 days caused a reduction in flowering rate. Figure 3 also showed that ET-based water productivity was in a reasonable agreement with cumulative irrigation, with 2008), Pimratch et al (2008) and Tojo Soler et al (2013) also reported that water deficit reduced the total dry matter of different peanut genotypes.…”

Drought stress is an important factor limiting the yield potential of peanut. In order to determine the effect of different irrigation scenarios on peanut production, field experiments were conducted in 2011 and 2012 growing seasons using factorial design with three replicates. On the other hand, the crop simulation models can be useful to predict crop yields and to investigate the impact of drought stress on plant growth and development. In this study, the Cropping System Model-Crop Growth (CSM-CROPGRO)-Peanut model was employed for the simulation of seed yield, pod yield, biomass, soil water balance components and water productivity for peanut in Astaneh-Ashrafiyeh, Iran. Results showed that the model was able to reasonably simulate seed yield, pod yield and final biomass for different irrigation scenarios (RMSEn < 20%, R 2 > 0.8 and d > 0.8). According to the results, irrigation depth and interval were important factors affecting yield and biomass. In general, model error increased as the amount of water applied decreased. The least amount of water applied (40 mm) resulted in yield reductions by 76%, 70% and 67% of the greatest amount of water applied (480 mm) for seed yield, pod yield and final biomass, respectively. For each irrigation interval, larger irrigation depth led to lower water productivity (WP) of irrigation (WP I ), but higher WP based on evapotranspiration (WP ET ) and transpiration (WP T ).The average amounts of WP I , WP ET , WP T based on seed yield were 1.2, 0.63 and 1.01 kg m −3 , respectively.
