“…An adequate supply of water is necessary for plant growth and hence crop yield, and water stress can affect normal growth processes such as cell expansion and regulation of photosynthesis [28]. However, water stress can affect different crops in different ways, for example the growth phase of hazelnuts [29] and the reproductive phase of peanuts [30] are particularly sensitive to water stress, whereas almonds are relatively drought resistant but do respond to severe water deficits during the stress-sensitive vegetative growth and post-harvest phases [31]. Similarly with pecans, the timing of applied water stress influences maximum nut production [32].…”

“…Firstly, yield measurements were inconsistent across the papers, for example some reported seed yield in tonnes/hectare or grams/nut/metre 2 , whilst others reported only yield components such as pod biomass or seed weight in grams. The effects of environmental stressors can affect plant growth at different stages, and therefore mediate their effect on different yield components such as seed or pod size, weight, branch number, plant biomass and total dry weight to differing extents [30,53]. Whilst we were unable to directly compare the absolute effect on yields, the change in percentage yields or yield components were calculated in order to facilitate some comparison between studies.…”

Background: Environmental changes are predicted to threaten human health, agricultural production and food security. Whilst their impact has been evaluated for major cereals, legumes and vegetables, no systematic evidence synthesis has been performed to date evaluating impact of environmental change on fruits, nuts and seeds (FN&S)-valuable sources of nutrients and pivotal in reducing risks of non-communicable disease. Methods: We systematically searched seven databases, identifying available published literature evaluating impacts of water availability and salinity, temperature, carbon dioxide (CO 2 ) and ozone (O 3 ) on yields and nutritional quality of FN&S. Doseresponse relationships were assessed and, where possible, mean yield changes relative to baseline conditions were calculated. Results: 81 papers on fruits and 24 papers on nuts and seeds were identified, detailing 582 and 167 experiments respectively. A 50% reduction in water availability and a 3-4dS m −1 increase in water salinity resulted in significant fruit yield reductions (mean yield changes: −20.7% [95%CI −43.1% to −1.7%]; and −28.2% [95%CI −53.0% to −3.4%] respectively). A 75%-100% increase in CO 2 concentrations resulted in positive yield impacts (+37.8%; [95%CI 4.1% to 71.5%]; and 10.1%; [95%CI −30.0% to 50.3%] for fruits and nuts respectively). Evidence on yield impacts of increased O 3 concentrations and elevated temperatures (>25°C) was scarce, but consistently negative. The positive effect of elevated CO 2 levels appeared to attenuate with simultaneous exposure to elevated temperatures. Data on impacts of environmental change on nutritional quality of FN&S were sparse, with mixed results. Discussion: In the absence of adaptation strategies, predicted environmental changes will reduce yields of FN&S. With global intake already well-below WHO recommendations, declining FN&S yields may adversely affect population health. Adaptation strategies and careful agricultural and food system planning will be essential to optimise crop productivity in the context of future environmental changes, thereby supporting and safeguarding sustainable and resilient food systems.

“…The more F increased, the more significantly PYs decreased. Other studies on PY reported that WD shows a decrease in fresh fruit of PY (Jain et al, 1997; Aydinsakir et al, 2016; Sezen et al, 2019). In this study however, the results showed that the PRZD treatments had the same value of IW with the DI treatments in both years, but the PRZD treatments achieved noticeably greater PY than the DI plots (Table 4).…”

“…Arioglu et al (2018) reported that the pod yield increased from 4185 to 5682 kg ha −1 when harvesting was delayed from 149 days after sowing (DAS) to 170 DAS in a 2-year average. Aydinsakir et al (2016) reported that based on the influence of yield decrease, water productivity (WP) and grain quality properties, peanut plants can be irrigated up to 100% of pan evaporation when there is no lack of moisture, and can be irrigated up to 75% of pan evaporation under WS situations. Aly et al (2016) reported that the highest values of WP were gained using an irrigation level of 50% available soil moisture (ASM) irrigation treatment followed by 25 and 75% ASM, and the differences were significant.…”

The aim of this study was to assess the impacts of varied irrigation regimes on the yield, irrigation water productivity (IWP) and crop water productivity (CWP) of Arachis hypogaea L. under pressurized irrigation in the southwest of Iran (Hamidiyeh, Khuzestan Province, Iran). The test was performed in a splitplot pattern. The main treatments were three irrigation frequencies (Fs) based on varied levels of cumulative pan evaporation (CPE) amounts (F 1 : 35 mm; F 2 : 60 mm; F 3 : 85 mm of CPE). The subtreatments were seven irrigation water levels (Is) (I 1 = 60%, I 2 = 85%, I 3 = 100%, I 4 = 135% (of actual evapotranspiration (ETc)), I 5 = PRZD 60 , I 6 = PRZD 85 and I 7 = PRZD 100 treatments) with four replications. The partial root-zone drying (PRZD) treatments received 60, 85 and 100% of the actual evapotranspiration (ETc), respectively, from replacing laterals. Crops were planted on 1 June 2017 and 1 June 2018. The results indicated that the F 2 I 4 treatment in both years showed the greatest peanut yield (PY). Moreover, in order to avoid greater PY loss the PRZD method was a proper and favourable option compared with traditional deficit irrigation (DI). However, PY declined by an average of 11.1 and 3.4% compared to the F 2 I 4 treatment in 2017 and 2018, respectively, but the F 2 I 7 treatment had about 16.3 and 16.1% lower water value than the F 2 I 4 treatment. PRZD treatments (I 5 and I 6) have effective amended PY than deficit irrigation treatments (I 1 and I 2) in both growing seasons, whereas these treatments received the same amount of moisture for all Fs (F 1 , F 2 and F 3). In the end, crop water productivity and IWP amounts also declined with rising irrigation frequency.

“…Irrigation is important factor in achieving high yield and seed quality of peanuts. Water deficit on peanut can decrease seed weight and percentage of extra-large kernels that reduce market quality (4) . Pre-harvest aflatoxin contamination of peanut is common when peanut is deprived of water, and soil temperature is high during the last 3 to 6 weeks of the pod maturation period (5) .…”

Background/Objectives: A study on enhancing peanut production through drip irrigation (DI) technology was conducted to increase the productivity and profitability of peanut production in the Ilocos region, Philippines. It sought to develop irrigation management strategies suitable for peanut. Methods/Statistical analysis: Decision Support System for Agrotechnology Transfer (DSSAT) simulation was done, and field validation was conducted to achieve the objectives. The simulation activity led to the determination of the top three promising drip irrigation management schemes suitable for peanut production, which were then field validated through actual field setup in three different locations. The best scheme (DI S9 410mm) was then pilot-tested at the farmers' field and compared with Farmers' Practice (FP) d using t-test. Findings: Using the DI scheme, dry pod yield was increased from 1.59Tha-1 to 2.09Tha-1 or 31.45% increase as compared to the farmer's practice. This result is a little higher than the target increase in yield of 30%. Findings indicate that the DI is a much better method than FP, increasing the dry pod yield to as much as 70.21% during the dry season. Yield increase could be attributed to more even application of water and less water stress. On the other hand, water productivity was only increased by around 16% due to farmers' limited water application. In terms of seed quality based on seed size, DI and FP are comparable. Results the economic analysis showed that yield of peanut under DI were higher by about 0.84Tha-1 to 1.16Tha-1 as compared to FP with a Return of Investment (ROI) of 0.25. In the long run, the profitability of DI could be improved through water productivity and yield improvements. Water savings was not a factor in profitability due to under-irrigation by farmers. Novelty/Applications: The use of DI technology with the developed irrigation scheme substantially contributed to the goal of increasing the productivity of and profitability of peanut. It is especially useful for areas with limited water supply for irrigation.
