Among the abiotic factors that causes threat to crop production, drought is one of foremost constraints in changing climatic era. Hence, a study was conducted mitigate effect stress blackgram with peanut shell carbon dots (PNS-CDs) as seed priming and foliar spray agent. Blackgram seeds were primed PNS-CDs at 200 ppm for 3 h plants sprayed 50 on 30th 45th DAS under conditions (30%, 50% 75% WHC). The imposed treatments included dry (control), water plants, PNS-CDs, combination both. results demarcate exemplary performance when given combined application (200 ppm) (50 terms its growth yield. Further, an increased activity catalase (12%), peroxidase superoxide dismutase (22%), glutathione reductase (60%), ascorbate (55%), H2O2 scavenging (32%) proline (35%) noticed over seeds, which confirmed antioxidant defense mechanism offered by PNS-CDs. In addition, percentage increase photosynthetic parameters like total chlorophyll (44%), soluble protein (54%), rate (89%), stomatal conductance (40%), internal CO2 concentration (74%) stability index (51%) role photosynthesis enhancer stress, resulted enhanced tolerance, plant Thus, it found followed 30 could serve sustainable alternative chemical inputs, ensuring better productivity tolerance water-limited environments. future research explore molecular mechanisms underlying different crops, biotic will also pave way broader agricultural sustainability eco-friendly approach.
