“…The simultaneous decrease in nitrate and water circulation from roots to shoots and the increase in root K + efflux tend to induce a potassium deficiency (Phukan, Mishra, & Shukla, 2016). As a matter of fact, waterlogging symptoms have been shown to be partly alleviated by foliar spraying of potassium (Ashraf et al, 2011;Dwivedi et al, 2017;Gautam et al, 2016).…”

K deficiency and waterlogging are common stresses that can occur simultaneously and impact on crop development and yield. They are both known to affect catabolism, with rather opposite effects: inhibition of glycolysis and higher glycolytic fermentative flux, respectively. But surprisingly, the effect of their combination on plant metabolism has never been examined precisely. Here, we applied a combined treatment (K availability and waterlogging) to sunflower (Helianthus annuus L.) plants under controlled greenhouse conditions and performed elemental quantitation, metabolomics, and isotope analyses at different sampling times. Whereas separate K deficiency and waterlogging caused well‐known effects such as polyamines production and sugar accumulation, respectively, waterlogging altered K‐induced respiration enhancement (via the C5‐branched acid pathway) and polyamine production, and K deficiency tended to suppress waterlogging‐induced accumulation of Krebs cycle intermediates in leaves. Furthermore, the natural 15N/14N isotope composition (δ15N) in leaf compounds shows that there was a change in nitrate circulation, with less nitrate influx to leaves under low K availablity combined with waterlogging and more isotopic dilution of lamina nitrates under high K. Our results show that K deficiency and waterlogging effects are not simply additive, reshape respiration as well as nitrogen metabolism and partitioning, and are associated with metabolomic and isotopic biomarkers of potential interest for crop monitoring.

“…Further, additional fertilization of 20-20 kg N-K 2 O/ha at 5-6 days after termination of submergence was found to be more promising and the most suitable fertilizer rate and application time for better recovery, crop growth, yield, and yield attributes of Swarna Sub1 in the submergence-prone ecosystem. Dwivedi et al (2017) also found that application of potassium at panicle initiation stage was more beneficial to enhance plant survival, better recovery and yield of rice during complete submergence. This might be because potassium mitigates submergence-induced stress in rice by maintaining survival after de-submergence and physiological activities (chlorophyll and antioxidant activity) to mitigate the adverse effect of submergence.…”

“…In particular, nitrogen has been reported to be the only possible limiting nutrient for rice production in flood-prone areas (Panaullah et al 2001). Similarly potassium application after de-submergence is also considered beneficial especially in submergence prone-areas (Gautam et al 2016b) as it has important role in mitigating submergence-induced stress in rice (Dwivedi et al 2017). Therefore, additional potassium along with N was applied to observe its effect on post submergence recovery.…”

Two field experiments were conducted at Regional Agricultural Research Station, Tarahara, Nepal during 2012 and 2013 to determine the effect of agronomic management on growth and yield of Swarna Sub1 under flash floods. The first experiment was laid out in a split plot design with three replications; and four different nutrient combinations at nursery as main plots and three age groups of rice seedlings as sub plots. The second experiment was laid out in a randomized complete block design and replicated thrice; with three post flood nutrient doses at six and 12 days after de-submergence (dad). The experiments were complete submerged at 10 days after transplanting for 12 days. The survival percentage, at 21 dad, was significantly higher in plots planted with 35 (90.25%) and 40 (91.58%) days-old seedlings compared to 30 days-old seedlings (81.75%). Plots with 35 days-old seedlings produced 5.15 t ha -1 with advantage of 18.83% over 30 days-old seedlings. Plots with 100-50-50 kg N-P 2 O 5 -K 2 O/ha at nursery recorded the highest grain filling of 79.41% and grain yield of 5.068 t/ha with more benefit. Post flood application of 20-20 N-K 2 0kg/ha at 6 dad resulted in higher plant survival and taller plants, leading to significantly higher grain yield of 5.183 t/ha and straw yield of 5.315 t/ha. Hence, 35-40 days old seedlings raised with 100-50-50 kg N-P 2 O 5 -K 2 O /ha in nursery and the additional application of20-20 kg N-K 2 O /ha at 6 dad improved plant survival and enhanced yield of Swarna Sub1 under flash flood conditions. The practice has prospects of saving crop loss with getting rice yield above national average yield leading to enhanced food security in the flood prone areas of Nepal. ;f/f+ z crfgs af9L cfPsf] cj:yfdf jfnL Joj:yfkgaf6 :j0f{ ;a ! wfgsf] a[ l¢ / pTkfbsTjdf kg] { c;/x?sf] cWoog ug{ o; If] qLo s[ lif cg' ;Gwfg s] Gb| , t/x/f, ;' g;/Ldf ;g\ @)!@ / @)!# ;fndf @ j6f kl/If0f ;+ rfng ul/Psf] lyof] . klxnf] kl/If0f :KnL6 Kn6 l8hfOgdf tLg k6s bf] xf] of{ O{ , ;fy} d" Vo Kn6df g;{ /L Aof8df dnsf $ j6f ljleGg dfqfx? / ;a Kn6df # j6f pd] /sf j] gf{ /flv ;+ rfng ul/Psf] lyof] . bf] >f] kl/If0fnfO{ klg # k6s bf] xf] of{ O{ /] g8dfOH8 sDfKnL6 Ans l8hfOgdf ;+ rfng ul/Psf] lyof] . h;df # j6f ljleGg dnsf] dfqf kfgL x6fOPsf] ^ / !@ lbgkl5 xflnPsf] lyof] . oL b' j} kl/If0fx?nfO{ /f] kfO{ u/] sf] !) lbg kl5 !@ lbg;Dd kfgLdf 8' afOPsf] lyof] . pSt kl/If0fx?af6 kfgL x6fOPsf] @! lbg kl5 #% lbgsf] j] gf{ df ()=@%Ü / $) lbgsf] j] gf{ df (!=%*Ü jfRg ;Sg] Ifdtf k| ltzt kfOof] .;fy} #% lbgsf] j] gf{ sf] pTkfbsTj %=!% 6g÷x] S6/ cyf{ t !*=*#Ü n] #) lbgsf] j] gf{ eGbf a9L kfOof] . g;{ /L Aof8df gfO6« f] hg, km:kmf] /; / kf] 6fl;od dnsf] dfqf !))M%)M%) s] =hL÷x] S6/sf] b/n] ;a} eGbf a9L k' i6 bfgf k| ltzt -&(=$!Ü_ / pTkfbsTj -%=)^* 6g÷x] S6/_ lbPsf] kfOof] . bf] >f] kl/If0fdf

9 10 analysis of spike metabolites was proceeded by LC-MS (liquid chromatograph-mass 32 spectrometry) firstly. Then the Heat-map, PCA, PLS-DA, OPLS-DA and response ranking 33 test of OPLS-DA model methods were used to analysis the function of differential metabolites 34 (DMs) during the rice panicle differentiation stage under abrupt drought-flood alteration. In 35 addition, relative quantitative analysis of spike total proteins under the treatment was 36 conducted iTRAQ (isobaric tags for relative and absolute quantification) and LC-MS. In this 37 study, 5708 proteins were identified and 4803 proteins were quantified. The identification and 38 analysis of DEPs function suggested that abrupt drought-flood alteration treatment can 39 promote carbohydrate metabolic, stress response, oxidation-reduction, defense response, and 40 energy reserve metabolic process, etc, during panicle differentiation stage. In this study 41 relative quantitative proteomics, metabolomics and physiology data (soluble protein content, 42 superoxide dismutase activity, hydrogen peroxidase activity, peroxidase activity, 43 malondialdehyde content, free proline content, soluble sugar content and net photosynthetic 44 rate) analysis were applied to explicit the response mechanism of rice panicle differentiation 45 stage under abrupt drought-flood alteration and provides a theoretical basis for the disaster 46 prevention and mitigation. 47 48 Abstract 49 Abrupt drought-flood alternation is a meteorological disaster that frequently occurs during 50 summer in southern China and the Yangtze river basin, often causing a significant loss of rice 51 production. In this study, a quantitative analysis of spike metabolites was conducted via liquid 52 chromatograph-mass spectrometry (LC-MS), and Heat-map, PCA, PLS-DA, OPLS-DA, and a 53 response ranking test of OPLS-DA model methods were used to analyze functions of 54 differential metabolites (DMs) during the rice panicle differentiation stage under abrupt 55 drought-flood alternation. The results showed that 102 DMs were identified from the rice 56 spike between T1 (abrupt drought-flood alternation) and CK0 (control) treatment, 104 DMs 57 were identified between T1 and CK1 (drought) treatment and 116 DMs were identified 58 between T1 and CK2 (flood) treatment. In addition, a relative quantitative analysis of spike 59 total proteins was conducted using isobaric tags for relative and absolute quantification 60 (iTRAQ) and LC-MS. The identification and analysis of DEPs functions indicates that abrupt 61 3drought-flood alternation treatment can promote carbohydrate metabolic, stress response, 62 oxidation-reduction, defense response, and energy reserve metabolic process during the 63 panicle differentiation stage. In this study, relative quantitative metabolomics and proteomics 64 analyses were applied to explore the response mechanism of rice panicle differentiation in 65 response to abrupt drought-flood alternation. 66 Keywords: Rice (Oryza sativa L.), abrupt drought-flood alternation, metabolomics, 67 p...
