“…According to Akhter et al, [2], addition of 0.1, 0.2 and 0.3% hydrogel increased the moisture retention at field capacity with a liniear correlation of r = 0.988, thus the amount of plant-available water was significant in both sandy loam and loam soils. The application of hydrogel can avoid moisture deficit and improve crop yield [3]. ) of maize…”

“…In many regions of the world, including India, drought stress is one of the most important factors that decrease agricultural crop production [1]. Maize is the third leading cereal crop of the world after wheat and rice [2][3][4][5][6][7]. In India, the crop is grown more than 76.03 lakh hectares under rainfed conditions (Agricultural Market Intelligence Centre, PJTSAU, 2021) with the erratic distribution of rainfall, and dry spell finally leads to reduced crop yields.…”

The advances and development in agriculture depend not only on mechanization and new hybrid seeds but also on the improvement of soil physical and chemical properties which in turn help to increase crop productivity in dry land soils. A field study was carried out to study the influence of superabsorbent polymer at 2.5 and 4.5 kg ha-1and humic acid at 15 and 30 kg ha-1 alone and their combinations with recommended 100% fertilizers on yield, uptake, and photosynthetic pigments of maize grown on rainfed alfisols at Regional Agricultural Research Station, Palem, Telangana. The experiment was laid out in randomized block design with three replications, consisting of nine treatments. Further, results showed that conjoint application of hydrogel@4.5 kg ha-1 + humic acid@30 kg ha-1 along with 100% RDF package significantly increased the pooled grain and stover yield (7136 and 8457 kg ha-1) of maize. Irrespective level of hydrogel and humic acid combinations with 100% RDF increased the macronutrient uptake by grain and stover, which further build up the total uptake. A similar pattern was also observed in corresponding to grain and stover yield.The chlorophyll “a”, “b” and total chlorophyll content (1.81, 1.69 1.54; 0.69, 0.62, 0.55 and 2.65, 2.46 and 2.24 mg g-1 in fresh plant weight at 30, 60 and 90 DAS) significantly influenced by application of hydrogel@4.5 kg ha-1+ humic acid@30 kg ha-1. In conclusion, the present investigation indicates the positive interaction between humic acid and super absorbent polymer which improved nutrient uptake and maize yield.

“…Moreover, this decrease creates a risk of secondary oxidative stress (Flexas et al 2006). Among the studies, several described a water-stress-induced decreased respiration rate in leaves or in different plant organs (Ghashghaire et al 2001;Haupt-Herting et al 2001;Mohammadkhani et al 2007) others showed almost unaffected (Ribas-Carbo et al 2005) or even increased respiration rates in water-stressed plants (Zagdanska, 1995).…”

Water stress has become the most uncontrolled and unpredictable factor, which is continuously limiting production in crops. Legumes are the major source of protein and are well-recognized for their nutritional benefits as well as their impact on the sustainability of agricultural systems are well known. Leguminous crops are severely affected by water stress causing alterations in various development processes. Proper nutrient management helps in attaining economical legume yields from drought-prone lands. The protective role of potassium in plants suffering from water stress has been documented and it positively influences plant capacity to adjust water stress conditions. This review compromises the information on the water stress-induced harmful effects on legumes growth, nitrogen fixation, gaseous exchange and mineral uptake parameters and proposes appropriate management by potassium application to alleviate the severity of water stres on above mentioned parameters. Application of potassium proved to meet higher yield from legume on cultivation under low/residual soil moisture availability conditions.

“…Seemingly, shortened flowering period and the adverse effect of water deficit stress on the existing photosynthesis and the loss of assimilates translocation into flowers were the main causes of the significant decrease in single-flower dry weight under severe water deficit stress. Also, Mohamadkhani and Heydari (2007) stated that the loss of leaf area resulted in the loss of light interception and the resulting loss of total photosynthesis capacity and obviously, the limitation of assimilate production under water deficit conditions led to the stunted growth of the plants and finally decreased their yield. The decrease in flower yield with the increase in water deficit stress has been reported for marigold (Saleem, 2009) and chamomile (Arazmjo et al, 2009), too.…”

In order to study the effect of water deficit stress and different nitrogen levels on flower yield and yield components of Calendula officinalis L., an experiment was conducted as split plot design based on randomized complete blocks with three replications, at research field of Islamic Azad University of Birjand branch in 2009.In this research water deficit stress set as main factor with three levels (irrigation after 60, 120 and 180 mm cumulative evaporation from pan class A) and nitrogen set as sub factor with four levels (0, 60,120 and 180 kg N.ha -1 ). The number of flowers per m 2 was 2.58 times greater in the treatment of irrigation after 120 mm accumulative evaporation than in the treatment of irrigation after 180 mm, but it showed an 11.2% loss compared with the treatment of irrigation after 60 mm accumulative evaporation. Also treatment of irrigation after 180 mm accumulative evaporation decrease of single flower weight by 13.3 and 18.2% at the treatments of irrigation after 120 and 60 mm accumulative evaporation, respectively. Means comparison showed that the increase in N fertilization rate from 0 to 180 kg N.ha -1 significantly increased the number of flowers per m 2 , flower fresh and dry yield by 33.7, 36.8 and 35.4% respectively. Finally, the results indicated that treatment of irrigation after 120 mm evaporation with 120 kg N. ha -1 application is suitable for marigold cultivation in Birjand.
