Drought stress is seen as the major abiotic stress in the modern day agriculture and hinders crop germination and seedling establishment and maize suffers the problem more as a summer season crop. Priming is a physiological method to overcome such deleterious effect of water stress with the main aim of increasing the germination of seed. A lab experiment was therefore performed with maize seed priming using Mannitol @ 0%, 2%, 4%, 6% and 8% (w/v) concentrations subjected to germination under induced drought of 0 Mpa, 0.15 Mpa, 0.5 MPa, 1.0 MPa and 1.7 MPa using NaCl. The experiment was laid in completely randomized design (CRD) with three replications. Priming with mannitol reduced the Mean Germination Time (MGT); the best result obtained in seeds primed with 2% mannitol. However, the final germination count, Relative Water Content (RWC) and root and shoot length remained unaltered. Germination activities reduced with increasing moisture stress. The study indicated that priming with mannitol could improve the speed of germination in maize seeds.

Plasma treatment is recognized as a suitable technology to improve germination efficiency of numerous seeds. The objective of this paper is to demonstrate whether cold air plasma can change the quality and quantity of wheat yield. Effects of cold plasma treatment on wheat (Pishgam variety) yield were studied by a randomized complete block design experiment at the Faculty of Agriculture of Tarbiat Modarres University, Iran, during 2015–17. Seeds were pre-treated with 80 W of cold plasma at four levels of time, 60, 120, 180 and 240 seconds. Plasma effects on yield and quality of wheat were determined by measuring plant photosynthesis, grain yield, biological yield, 1000-grain weight, total chlorophyll, carotenoid, anthocyanin, protein and starch content. Results showed that plasma treatments had positive effects on wheat characteristics, and treatment of 180 s had the highest stimulatory effect. In both years, cold plasma increased grain yield at 180 s, but decreased it at 240 s compared with control. The rate of plant photosynthesis, grain yield, 1000-grain weight, carotenoid and anthocyanin were enhanced at 180 s. The starch content and grain protein were enhanced at 120 s cold plasma application compared with control.

“…Pre-sowing seed priming is one such technology [27] that suggests that the yield gap in DSR compared to PTR caused by poor crop establishment can be closed with seed priming technology. Improved seed invigoration techniques, such as seed priming for its positive impacts including rapid and uniform crop establishment, early vigor, and yield gains, have been studied in various crops including mungbean [28], soybean [29], sorghum [30], wheat [31,32], and maize [33,34], and vegetables such as tomato [35]. Recently, with increased interest in transitioning from PTR to DSR, limited studies have been conducted on rice seed priming [36,37].…”

Poor early growth and uneven crop establishment are reported as the major bottlenecks in wide-scale adoption and optimal yield realization of dry direct-seeded rice (DSR). Seed priming can potentially help overcome these problems in DSR. Therefore, laboratory and field studies were conducted at Punjab Agricultural University, Ludhiana, India, during kharif/wet-season 2018 and 2019 to evaluate the effect of different priming techniques on germination, establishment, growth, and grain yield of rice under DSR conditions. The following priming treatments were evaluated: dry non-primed seed (control), hydropriming with distilled water, halopriming with 2.0% potassium nitrate, hormopriming with 50 ppm gibberellic acid (GA3), and osmopriming with polyethylene glycol (PEG)(−0.6 MPa), each with 12 and 24 h priming duration. In 2019, priming treatments were tested under two DSR establishment methods—conventional DSR (sowing in dry soil followed by irrigation) and soil mulch DSR (locally known as vattar DSR) (sowing in moist soil after pre-sowing irrigation), whereas in 2018, priming treatments were evaluated under conventional DSR only. In both years, halopriming and hormopriming resulted in a 7–11% increase in rice yields compared to non-primed dry seed (control). Osmopriming resulted in a 4% yield increase compared to control in 2018 but not in 2019. The higher yields in halopriming and hormopriming were attributed to higher and rapid germination/crop emergence, better root growth, and improvement in yield attributes. Priming effect on crop emergence, growth, and yield did not differ by DSR establishment methods and duration of priming. Conventional DSR and soil mulch DSR did not differ in grain yield, whereas they differed in crop emergence, growth, and yield attributes. These results suggest that halopriming with 2.0% potassium nitrate and hormopriming with 50 ppm GA3 has good potential to improve crop establishment and yield of rice in both conventional and soil mulch DSR systems.
