“…Results showed that 2% SSP recorded higher seed yield of 1705 kg/ha with significantly higher N uptake. Sharma et al, (2013) conducted an experiment to study the various seed priming methods for seed germination, seedling vigour and fruit yield in okra. Seeds were subjected to four priming methods, namely, hydro-priming, osmopriming, halo-priming and solid matrix along with control.…”

“…It is concluded that seed priming may serve as an appropriate treatment for accelerating the emergence of sorghum genotypes studied. Meena et al, (2013) conducted an experiment for two consecutive years 2010-11 and 2011-12 to evaluate the influence of hydro-priming grain yield of wheat. The experiment was conducted with seed priming treatments (dry seed, hydro-priming, and pre-germinated seeds) in subplots.…”

Germination and seedling emergence are the critical stages in the plant life cycle. Insufficient seedling emergence and inappropriate stand establishment are the main constraints in the production of crops which receiving less rainfall. Farmers do not have sufficient resources to meet the requirement of seedbed preparation for sowing and they are at more risk as compared to progressive farmers. On the other hand good establishment increases competitiveness against weeds, increases tolerance to drought period, increase yield and avoids the time consuming need for re-sowing that is costly too. It is well accepted fact that priming improves germination, reduces seedling emergence time and improves stand establishment. A method to improve the rate and uniformity of germination is the priming or physiological advancement of the seed lot. The general purpose of seed priming is to partially hydrate the seed to a point where germination processes are begun, but they would exhibit rapid germination when re-imbibed under normal or stress conditions. A lot of work has been done on seed priming and results of these studies indicate well the importance of priming to get a good crop stand in many crops of tropical region such as rice, maize, sorghum and pigeon pea.

“…Interaction between treatments and soaking time revealed that hydro priming with 2 hrs priming duration was most effective for enhancing the rate of germination. Meena (2013) found that seed hydropriming resulted in earlier seedling establishment, which contributed to better crop stand, increased tillering and higher grain yield in wheat than dry seed control. On the contrary, seed priming with KNO improved cotton emergence in green house as compared to hydropriming (Ahmadvand ., 2012b).…”

Aim : Methodology :Results : Interpretation :High temperature during sowing of cotton results in poor emergence and high seedling mortality, thus leading to poor crop stand and reduced yield. Improvement in germination by seed priming may combat this problem as this physiological technique results in faster and synchronous seed germination. Hence, studies were conducted to evaluate the effect of different temperature regimes, seed priming and also duration of priming on germination and seedling growth to determine and exploit their usefulness in improving cotton seed germination for better seedling establishment.Seeds of cotton hybrid (Ankur 3028 BGII) were primed separately with water and KNO at different concentrations (2.5, 5.0, 7.5 & 10.0%) for 2, 4 and 6 hrs. Non-primed seeds and hydro primed seeds for 4 hrs were considered as control. Seeds for each set of treatment were placed on moistened filter paper in petri dish. Each treatment was then divided into two sub-sets for assessment of seedling response at two temperature regimes 25°C and at ambient temperature of 32-38.5°C. After 7 days, final germination percentage, root length, shoot length and fresh weight of seedling were measured at both temperature regimes. Germination count was recorded on daily basis and was used to calculate speed of germination.Primed seeds exhibited an increase in germination by 43% and 34% than control (non-primed seeds) at ambient temperature (32-38.5°C) and 25°C respectively. Germination speed also improved by 61% and 67% respectively at ambient temperature and 25°C over control. Hydropriming resulted in highest germination (75.5 and 79.2%), germination speed (5.13 and 6.63 days), root length (4.68 and 6.30 cm) and shoot length (2.59 and 3.40 cm) than control at 25°C and ambient temperature respectively. Contrarily, increase in KNO concentration caused deleterious effects on root and shoot length.Cotton seed germination was higher at ambient temperature (32°-38.5°C) than 25°C and priming improved germination potential of seeds. Hydropriming was more effective than KNO for enhancing germination percentage, germination speed and seedling growth at both temperature regimes. Studies concluded that hydro priming of cotton seeds improved germination, a key factor for better crop stand having positive effect on crop survival, and consequently improved cotton productivity.

“…Hence it can be concluded that primed seeds have suppressive effect on weeds. Halopriming enhanced the competitive ability of wheat crop against weeds (Meena et al, 2013). Effect on water use efficiency: Early and synchronized field emergence observed in seed priming treatments resulted in more leaf area and early canopy development.…”

Seed priming is controlled hydration of seeds to a level that allow pre-germinative metabolic activity to continue, but interrupt the emergence of the radicle. Seed priming improves seed performance, ensures uniformity and better establishment, enhances the yield in diverse environments, greater tolerance to environmental stress and helps to overcome dormancy. Change in seed water content, cell cycle regulation, modification of seed ultrastructure, management of oxidative stress and reserve mobilization are the major physiological and biochemical changes takes places during seed priming. Priming methods adopted should be simple and affordable for its easy spread and adaptability. Seed priming should be influenced by factors such as light, aeration, temperature, time and seed quality. Different methods of priming are hydropriming, osmopriming, halopriming, solid matrix priming, biopriming and hormonal priming. Seed priming had significant effect on agriculture. It will hasten and synchronize the germination, enhances the plant growth, have better stress resistance, increase the use efficiency of nutrients and water and have better weed suppression effect. The review paper discusses about seed priming, physiological and biochemical changes in seed priming, different methods of seed priming and its role in sustainable agriculture.
