“…Treatment irrigated at 60% MAD level showed 83.4% increase in average Total water productivity and 74.4% increase in average irrigation water productivity as compared to farmers' practice during both the experimental seasons. As reported by Mila et al (2017), the TWP and IWP of productivity (NEWP) varied from 5.7 to 19.9 Rs m (Table 6).…”

“…There are various factors which influence the metabolism of plants, changing the processes of growth and development of plants as well as increasing their resistance to stress factors (Vladimir et al, 2020). But fresh water is an essential and the most critical input for sustainable agricultural production and productivity (Mila et al, 2017). However, the increasing water scarcity is a major constraint in fulfilling the irrigation water demands of Indian agriculture (Das et al, 2018).…”

Aim: To study the effect of deficit irrigation on yield and water productivity of sunflower in East and South eastern coastal plains of Odisha. Methodology: The present study on water productivity was undertaken using hybrid sunflower (Swathi: NSFH-145) with application of deficit irrigation having Management Allowable Deficit level of 20%, 40%, 60% and one farmers’ practice of 70% MAD level of irrigation. Growth attributes like leaf area Index, plant height, and head diameter were recorded at 20, 45, 65 and 80 days after sowing. Yield attributes like 1000 seed weight (test weight), above ground biomass and grain yield, were recorded after threshing. Results: The growth, yield and water productivity of sunflower were significantly influenced by different irrigation levels. Irrigation scheduling at 20% MAD level showed the highest grain yield, while the lowest yield was obtained from the farmers’ practice. Irrigation at 60% MAD level showed the highest water productivity when compared with farmer’s practice as it produced the highest yield per unit quantity of water application of 0.85 kg m-3 and also produced the highest average benefit to cost ratio of 2.08. Interpretation: Taking the yield, water productivity and benefit-cost ratio into account, irrigation at 60% MAD level was found to be the best. However, irrigation at 50% to 60% MAD level may be suggested for growing sunflower under water scarce conditions in sandy loam soil for increasing water productivity.

“…Water stress significantly reduced head diameter of sunflower and maximum reduction in head diameter happened when crop encountered water deficit at flowering over vegetative stage (Hussain et al, 2015(Hussain et al, , 2017. This decrease was due to reduction in photosynthates production (Dong et al, 2017;Mila et al, 2017) and their minimum distribution to the floral parts (Dong et al, 2017). Spraying of 10 µM ABA under water deficit at flowering stage considerably enhanced head diameter because abscisic acid useful in water maintenance response of plants and may have enhanced plant growth through improvement in water use efficiency (WUE) (Wei et al, 2015;Dong et al, 2017).…”

“…Contrarily ABA foliar application may increment the action of definite enzymes such as ribonuclease and α-amylase. These enzymes may be involved in breakdown of starches plus other related materials thus making osmotic potential more adverse (Dong et al, 2017;Mila et al, 2017). Water stress at vegetative or flower initiation stage considerably decreased turgor pressure of leaf.…”

Enhancement in yield and quality of sunflower by foliar spray of abscisic acid (ABA) under water deficit condition was studied during 2016 and 2017. Three irrigation treatments were applied. Four irrigations (at 4-6 leaf, at vegetative, at flowering and at grain formation stage), three irrigations (at 4-6 leaf, at pre flowering and at grain formation stage), three irrigations (at 4-6 leaf, at vegetative and at grain formation stage). Sunflower hybrid (S-278) was sprayed with different ABA concentrations (0, 10 µm and 20 µm) at 4-6 leaf, vegetative, flowering and grain formation stage. Foliar application of 10 µM ABA under water stress at vegetative stage significantly enhanced plant height, head diameter, achene yield and biological yield. It also enhanced sunflower water relations by increasing water potential. ABA application and water deficit showed opposite results for yield and oil quality. Water deficit at vegetative or at flowering stage maximized stearic and oleic acid contents and minimized palmitic and linoleic acid contents, whereas foliar spray of ABA under water stress at both stages reduced stearic and oleic acid but maximized palmitic and linoleic acid.

“…For example, significant increases in yield were attained by improving seedling vigor in grain sorghum ( Sorghum bicolor L.) and spring maize ( Zea mays L.) (Malm, 1968; ur Rehman et al, 2015), enhancing photosynthetic efficiency in tobacco ( Nicotiana tabacum L.) and shortgrass steppe (Kromdijk et al, 2016; Morgan et al, 2001; Zhu et al, 2010), and enhancing root traits in wheat ( Triticum aestivum L.), maize, and sugarbeet ( Beta vulgaris L.) (Comas et al, 2013; Vazifedoust et al, 2008). From field management, one of the proposed strategies to improve water productivity is through DI management, which reduces irrigation inputs relative to the full crop water demand while minimizing yield reductions (Geerts and Raes, 2009; Mila et al, 2017).…”

The use of deficit irrigation (DI) management in growing crops tolerant of the semiarid conditions in West Texas may save irrigation without significant yield penalties. Field experiments were conducted at New Deal, TX, in 2017 and 2018 to determine the effects of four levels of DI (extreme, severe, moderate, and mild) on the seed yield, yield components, harvest index (HI), and oil content of three oilseed crops: sesame (Sesamum indicum L.), safflower (Carthamus tinctorius L.), and sunflower (Helianthus annuus L.). Combined irrigation and precipitation equivalent to 345 mm applied throughout the crop's life cycle was sufficient to maintain growth and development without significant penalties to the yield, yield components, HI, and oil content of the crops. Seed yields ranged from 1241 to 1359 kg ha−1 in sesame, 1365 to 1676 kg ha−1 in safflower, and 1174 to 3367 kg ha−1 in sunflower. Oil content of sesame ranged from 50.1 to 52.3%, oil content of safflower ranged from 35.4 to 39.5%, and oil content of sunflower ranged from 24.0 to 46.8%. Heavy precipitation from vegetative to reproductive stage caused favorable conditions for pest proliferation and damage to sunflower, highlighting a possible pitfall due to its pest susceptibility. Results demonstrate that sesame, safflower, and sunflower are potential low‐input oilseed crops that can grow under DI conditions without significant reductions to yield and oil content. In conjunction with economic evaluations, these results can be useful when developing or re‐assessing guidelines for optimal agronomic practices involving non‐traditional crops under reduced irrigation. Core Ideas Low water input can support acceptable growth and yield for oilseed crops. Oilseed crops acclimatize to water deficit conditions to maintain productivity. Deficit‐adapted crops thrive under low precipitation during growth. Deficit‐adapted crops can maintain productivity despite reduced water application.
