“…In chickpeas, foliar spray with 0.001 mM was found to be more effective than the treatment of the same dose through other application methods, so we recommend a 0.001 mM dose of calliterpenone as a foliar spray in chickpeas. These findings are in agreement with several recent studies that also found that foliar sprays of PGRs at limited concentrations significantly improve the growth as well as yield attributes in rice (Prajapati et al, 2021), wheat (Zhang et al, 2017;Dawar et al, 2021), potato (Thornton et al, 2013), tomato (Choudhury et al, 2013), onion (Ghani et al, 2021), and chickpea (Rafique et al, 2021).…”

“…Gibberellins (especially gibberellic acid) are important PGRs used for increasing the economic yields of various crops. These have been found effective in rice (Gavino et al, 2008 ; Tiwari et al, 2011 ; Prajapati et al, 2021 ), wheat (Pavlista et al, 2014 ; Amram et al, 2015 ; Zhang et al, 2017 ; Dawar et al, 2021 ), potato (Thornton et al, 2013 ), tomato (Choudhury et al, 2013 ), cotton (Copur et al, 2010 ), sweet pepper (Maboko and DuPlooy, 2015 ), Pyrethrum (Singh et al, 2011 ), peppermint (Khanam and Mohammad, 2017 ), onion (Ghani et al, 2021 ), and chickpea (Rafique et al, 2021 ). However, the higher cost of gibberellins has restricted their use to high-value crops only.…”

The global population is rising at an alarming rate, which is threatening food and nutritional security. Although chemical fertilizers and pesticides are important for achieving food security, their excessive usage critically affects soil health and adds up residues in the food chain. There is an increasing interest in identifying eco-friendly farm inputs that can improve crop productivity through sustainable agricultural practices. One of the most common approaches to reducing chemical inputs in agriculture is the use of plant growth regulators (PGRs). Here, we demonstrate the benefits of a natural and novel plant growth enhancer “calliterpenone,” isolated from Callicarpa macrophylla, a medicinal plant, for increasing crop productivity in six crops, viz., rice, wheat, potato, tomato, chickpea, and onion. Results revealed that the application of calliterpenone (foliar spraying or seed soaking) enhanced the yield of rice (28.89%), onion (20.63%), potato (37.17%), tomato (28.36%), and chickpea (26.08%) at 0.001 mM and of wheat (27.23%) at 0.01 mM concentrations in comparison to control. This enhancement in yield was reflected through improvements in its growth attributes, viz., spike length, tillers plant−1, seeds spike−1, plant height, and biomass. Furthermore, the exogenous application of calliterpenone could increase the endogenous level of indole-3-acetic acid (IAA) in all tested crops and decrease the content of abscisic acid (ABA) in a few. Trials conducted at farmers' fields showed an overall ~12% increase in rice yield (mean of 11 farmers' fields ranging from 3.48 to 19.63%) and ~10% increase in wheat yield (ranging from 3.91 to 17.51%). The 0.001 mM of calliterpenone was the best effective dose for most crops except wheat, where a concentration of 0.01 mM was found to be the most optimal. This study indicates that calliterpenone is a natural plant growth promoter that can be used in boosting the yields of multiple crops and would be an important input component of organic farming.

“…Plant scavenging system also developed positively under PGR application. Foliar use of such plant growth regulators enhances the growing abilities of plant against pathogenic and abiotic stress (Ghani et al, 2021). Besides this, a definite increase in chlorophyll pigments was observed too.…”

Exogenous application of glutamic acid promotes cucumber (Cucumis sativus L.) growth under salt stress conditions

Salinity is expected to be the major destructive abiotic stress that causes ionic and oxidative damage leading to growth reduction and ultimately plant death. Glutamic acid (GA) is an α-amino acid that is used by almost all living beings in the biosynthsis of proteins. Therefore, in the present study, we tried to investigate the effect of foliar application of glutamic acid (GA) on cucumber (Cucumis sativus L.) under altered salinity levels. Cucumber seedlings were grown in plastic pots under greenhouse conditions by applying four levels of salinity (0, 3 dS/m, 6 dS/m and 12 dS/m) and two levels of foliar applied GA (0, 10 mM). Salinity was induced by mixing the salt and soil before seed sowing; however, exogenous GA was applied when the vine length was reached up to maximum height. Morphological characters showed disruptive response under saline conditions especially in indigenous cultivar (local cucumber represented as V1). Enhanced activities of superoxide dismutase (0.29 u g-1 FW), guaiacol peroxidase (3.51 u g-1 FW) and ascorbate peroxidase (0.39 µmol AsA.mg-1 Chl min-1) were observed in salt-stressed cucumber leaves. Both varieties showed unusual behavior for malondialdehyde in decreasing manner with increasing salinity levels (2.0333 µmol g-1 FW at 12dS/m in local cultivar; while, 1.98 µmol g-1 FW at 12dS/m in hybrid cultivar SSC-228). However, exogenously applied GA played a beneficial role in promoting all morphological parameters under stress with increasing scavenging abilities against reactive oxygen species. Foliar application of GA improved plant defense mechanism with minimum destruction. Remarked calculations showed that under salt stress, GA improved plant stress tolerance against salinity by maximizing the growth rate.

“…In plants, especially in periods when their uptake is limited and their requirements are high, nutrients must be taken from the leaves. Foliar sprays are the most effective and very rapid treatment (Fernandez et al, 2013;Ghani et al, 2021). The use of foliar fertilizer is common due to these properties (Rios et al, 2019).…”
