“…Pattanashetti et al [43] also observed enormous genetic variation in SCMR reading of groundnut mini core collection across five growth stages. Similar results were also reported by Mann et al [44] and Song et al [45], where lower SPAD values were recorded in no Fe received plants (-Fe) as compared to the plants treated with iron. This might be due to the association of iron in the biosynthesis of the porphyrin ring of chlorophyll.…”

Aims: In the present study twenty groundnut genotypes are evaluated for their resistance to IDC and to identify feasible indicators for screening iron (Fe) efficient groundnut genotypes in calcareous soils based on the morphophysiological parameters at 45 days after sowing (DAS). Study Design: The experiment was replicated three times with two iron treatments (+Fe and – Fe) in a randomized block design Place and Duration of Study: Field screening of genotypes was carried during Kharif 2019 at Thondamuthur block, Coimbatore district (10°59’31.9” N 76°47’15.4 E), Tamil Nadu, India. Methodology: The randomized field experiment was comprised of two major factors, i) Fe status (with Fe, without Fe), and ii) genotypes (twenty) with differential IDC response. Seven morpho-physiological parameters associated with IDC resistance were evaluated in groundnut genotypes. Results: Under Fe deficit conditions, IDC efficient genotypes recorded significantly higher shoot dry weight, root dry weight, root volume, SPAD values, active Fe, catalase activity, peroxidase activity, and higher yield compared to susceptible ones because of better Fe utilization efficiency. The various morpho-physiological parameters studied showed a significant correlation with pod yield. The four genotypes viz., TAG 24, CO 7, VRI 8, and VRI-16086 were efficient under both sufficient and deficit conditions under calcareousness. The stepwise multiple regression shows the peroxidase (POD) accounts for 71 % under +Fe condition and SPAD accounted for 66 percent in -Fe in predicting the pod yield. Hence, POD and SPAD can be used as indicators for selecting Fe efficient groundnut cultivars for calcareous soil. Conclusion: The findings indicate that SPAD values are most optimal for the initial large-scale screening of groundnut genotypes for tolerance to IDC, whereas peroxidase may be used to validate established genotypes.

“…In present experiment, the response of these two genotypes to various foliar applications was studied. Foliar application of Fe is a common mean to correct Fe deficiency in agricultural crops (Mann et al 2017;Álvarez-Fernández et al 2005).…”

“…Foliar applications of various chemicals are useful in combating Fe deficiency. Foliar applications of FeSO 4 can increase leaf Fe concentration, while basal treatments are more effective for long results (Mann et al, 2017). Under 21 days of Fe deficiency treatment, foliar applications of salicylic acid and sodium nitroprusside in combination increased the level of chlorophyll, active Fe and increased Fe accumulation was observed in cell organelles showing less symptoms of interveinal chlorosis (Kong et al 2014) Different foliar applications containing (FeSO 4 .7H 2 O, Fe(III)-citrate, Fe(III)-EDTA, Fe(III)-DTPA, Fe(III)-IDHA) and a surfactant were able to correct Fe deficiency in Prunus persica L. Foliar applications always resulted in leaf chlorophyll increase, although different degrees of re-greening were observed for the various Fecompounds tested.…”

In present study, different foliar treatments were applied on peanut to check their ameliorative effect on Fe deficiency. In hydroponics experiments, foliar applications of FeSO 4 , Fe-EDTA, sequestrene and ferric chloride were applied to check their effect on Fe deficiency chlorosis in two varieties of peanut already screened as BARI-2000 (Fe deficiency tolerant) and BARD-699 (Fe deficiency sensitive). Sequestrene proved to be more effective in increasing the growth of plant. Photosynthetic rate increased up to 58 and 70% in BARI-2000 and BARD-699 respectively as compared to control with foliar application of sequestrene. Similarly higher active Fe concentration was recorded in both genotypes. Up to 14 and 41% increase in active Fe concentration was observed. Various morpho physiological parameters including root length, shoot length, root fresh weight, root dry weight, shoot fresh and shoot dry weights, SPAD values, photosynthetic and transpiration rates showed that BARD-699 was more responsive to foliar applications, while foliar application of sequestrene can be used in correcting Fe deficiency in both genotypes. Active Fe was significantly correlated with different morphological parameters in both genotypes. The results of presense experiment suggested that foliar applications were helpful in correction Fe deficiency in peanut and growth can be enhanced.

“…Calcareous soils cover major cultivated land of south Mediterranean lands, which decreased crop growth and yield under low Fe availability. A lot of research showed that the most obvious effect of Fe deficiency is a decrease in the amount of chlorophyll pigments [ 7 , 8 ]. Therefore, there is a close relationship between plant growth and photosynthesis [ 7 , 9 ].…”

“…Therefore, there is a close relationship between plant growth and photosynthesis [ 7 , 9 ]. In fact, Mann [ 8 ] and Ren [ 9 ] showed that plants responded strongly to iron deficiency in physiological traits where chlorophyll content and plant biomass were reduced [ 10 ]. Hence, in calcareous soils, cultivating Fe-efficient plants is important for maintaining yields while enhancing environmental sustainability.…”

The aim of this study was to assess the effect of symbiotic bacteria inoculation on the response of Medicago truncatula genotypes to iron deficiency. The present work was conducted on three Medicago truncatula genotypes: A17, TN8.20, and TN1.11. Three treatments were performed: control (C), direct Fe deficiency (DD), and induced Fe deficiency by bicarbonate (ID). Plants were nitrogen-fertilized (T) or inoculated with two bacterial strains: Sinorhizobium meliloti TII7 and Sinorhizobium medicae SII4. Biometric, physiological, and biochemical parameters were analyzed. Iron deficiency had a significant lowering effect on plant biomass and chlorophyll content in all Medicago truncatula genotypes. TN1.11 showed the highest lipid peroxidation and leakage of electrolyte under iron deficiency conditions, which suggest that TN1.11 was more affected than A17 and TN8.20 by Fe starvation. Iron deficiency affected symbiotic performance indices of all Medicago truncatula genotypes inoculated with both Sinorhizobium strains, mainly nodules number and biomass as well as nitrogen-fixing capacity. Nevertheless, inoculation with Sinorhizobium strains mitigates the negative effect of Fe deficiency on plant growth and oxidative stress compared to nitrogen-fertilized plants. The highest auxin producing strain, TII7, preserves relatively high growth and root biomass and length when inoculated to TN8.20 and A17. On the other hand, both TII7 and SII4 strains improve the performance of sensitive genotype TN1.11 through reduction of the negative effect of iron deficiency on chlorophyll and plant Fe content. The bacterial inoculation improved Fe-deficient plant response to oxidative stress via the induction of the activities of antioxidant enzymes.
