“…(2006) and Kannan et al. (2017) also support the findings of this study. Poor microbial activity at elevated temperature coupled with low moisture conditions could explain the reduced impact of PPFM under the harsh conditions of north India.…”

“…Application of PPFM improved SCY only under mild water stress over the control, while under severe stress, the yield increment was trivial. The slight effects of PPFM application on cotton and sugarcane due to release of various sugars and alcohols on the leaf surface as reported by Madhaiyan et al (2006) and Kannan et al (2017) also support the findings of this study. Poor microbial activity at elevated temperature coupled with low moisture conditions could explain the reduced impact of PPFM under the harsh conditions of north India.…”

“…Similarly, potassium nitrate (Hussain et al, 2020; Shahzad et al, 2019) and urea (Shalaby, 2018) applications also exhibited potential to induce abiotic stress resilience among field crops. Microbes such as pink pigmented facultative methylobacteria (PPFM) have been shown to affect the release of some sugars and alcohols and improve SCY under moisture stress when combined with cotton stalk biochar/crop residue mulch (Kannan et al., 2017).…”

In north-western India, short-term droughts due to insufficient rainfall or irrigation canal closures are common. To quantify seed cotton yield (SCY) loss under moisture deficit and evaluate the efficacy of foliar-applied osmo-protectants (OPs), a 2-year field experiment was conducted with three moisture regimes (M 1 : well watered, M 2 : rainfed after single post-sowing irrigation [POSI], and M 3 : rainfed after two POSIs) in main plots and eight OPs (S 1 : control, S 2 : four sprays of 2% urea at weekly intervals, S 3 : four sprays of 2% KNO 3 at weekly intervals, S 4 : single spray of 500 mg kg −1 thio urea [TU], S 5 : single spray of 50 mg kg −1 salicylic acid [SA], S 6 : single spray of 100 mg kg −1 glycine betaine [GB], S 7 : single spray of 100 mg kg −1 SA, and S 8 : three sprays of 1% pink pigmented facultative methylobacteria at 10 days interval) in sub-plots of a split plot design. Moisture stress induced a reduction of relative water content (RWC) and consequently decreased SCY by 17% and 32.9% under M 3 (2821 kg ha −1 ) and M 2 (2291 kg ha −1 ), respectively, compared to M 1 (3418 kg ha −1 ). Except for TU, all tested OPs improved SCY by 6.3%-23.7% in comparison to the nontreated control. Application of SA and GB enhanced photosynthesis, improved stomatal conductance, and maintained higher RWC. Application of SA at 100 mg kg −1 resulted in an additional income of US$458 ha −1 and was the most economical treatment for countering short-term drought.
