“…Compared to unprimed seeds (control) except treatment T 5 (nutripriming with ZnSO 4 0.025 per cent + borax 0.01 per cent), the other treatments recorded higher germination per centage, germination index, speed of germination and mean daily germination. The result is in conformity with the findings of Farooq et al (2007) and Sajjan et al (2017) who observed that the seed priming enhanced the germination rate, better allometric attributes, faster emergence of seedlings as well as early germination. Faster emergence of primed seeds might be due to metabolic repair during imbibition (Bray et al, 1989) and build of germination enhancing metabolites (Basra et al, 1995), while higher and synchronized emergence was the consequence of reduced physiological non-uniformity in the seeds due to priming (Juraimi et al, 2012).…”

The experiment was conducted at Coconut Research Station, Balaramapuram with an objective to study the effect of nutripriming with ZnSO4 and borax on the early growth and seedling vigour and Zn and B content in grain cowpea. Nutripriming treatments had significant effect on germination parameters. Nutripriming with ZnSO4 either at 0.025 or 0.05 per cent recorded higher values for the germination parameters. These treatments recorded 19.68 and 18.51 per centage higher germination than control. Germination index was 1.4 times higher in seeds primed with ZnSO4 @ 0.025 and 0.05 per cent and also recorded higher values for mean daily germination and speed of germination. The highest co-efficient rate of germination and germination rate index was recorded by seed priming with ZnSO4 at 0.05 per cent and it was closely followed by ZnSO4 @ 0.025 per cent for 4 h. Nutripriming with ZnSO4 either @ 0.025 or 0.05 per cent recorded the lowest mean germination time and time to reach 50 per cent germination and also recorded higher Zn and B content. Vigour index also followed the same trend. Hence it can be concluded that nutripriming with ZnSO4 either at 0.025 or 0.05 per cent can be recommended for early seedling growth, seedling vigour and higher Zn and B content in grain cowpea.

“…Seed priming ensures increased and uniform germination by reducing the imbibition time [27], increasing the pre-germinative enzyme activation, increasing metabolite production [28], repairing the damaged DNA [29], and regulating osmosis. There are many reports on seed priming toward improving seed germination, seedling emergence, stand establishment, crop growth, nodulation, and productivity in various crop species viz., rice [30][31][32], wheat [33,34], pulses [35][36][37][38][39][40][41], okra [42], Chinese cabbage [43], sunflower [44], and melons [45]. Seed priming induces antioxidant activity and storage protein solubilization and minimizes lipid peroxidation [46].…”

Drought is a serious threat to the farming community, biasing the crop productivity in arid and semi-arid regions of the world. Drought adversely affects seed germination, plant growth, and development via non-normal physiological processes. Plants generally acclimatize to drought stress through various tolerance mechanisms, but the changes in global climate and modern agricultural systems have further worsened the crop productivity. In order to increase the production and productivity, several strategies such as the breeding of tolerant varieties and exogenous application of growth regulators, osmoprotectants, and plant mineral nutrients are followed to mitigate the effects of drought stress. Nevertheless, the complex nature of drought stress makes these strategies ineffective in benefiting the farming community. Seed priming is an alternative, low-cost, and feasible technique, which can improve drought stress tolerance through enhanced and advanced seed germination. Primed seeds can retain the memory of previous stress and enable protection against oxidative stress through earlier activation of the cellular defense mechanism, reduced imbibition time, upsurge of germination promoters, and osmotic regulation. However, a better understanding of the metabolic events during the priming treatment is needed to use this technology in a more efficient way. Interestingly, the review highlights the morphological, physiological, biochemical, and molecular responses of seed priming for enhancing the drought tolerance in crop plants. Furthermore, the challenges and opportunities associated with various priming methods are also addressed side-by-side to enable the use of this simple and cost-efficient technique in a more efficient manner.

“…The size of the individual seed also plays a major role in the seed germination quality. Large sized seeds in pigeon pea recorded a higher percentage of germination and field emergence [ 16 , 17 , 18 ]. These properties are affected by numerous factors such as size, form, moisture content of the grain [ 19 ] and varieties [ 20 ].…”

The objective of this study was to explore the physical properties of maize seeds in competition with weeds. The basic and complex geometric characteristics of seeds from maize plants, competing with Datura stramonium L. (DS) or Xanthium strumarium (XS) at different weed densities, were studied. It was found that the basic and complex geometric characteristics of maize seeds, such as dimension, aspect ratio, equivalent diameter, sphericity, surface area and volume, were significantly affected by weed competition. The increase in weed density from 0 to 8 plants m2 resulted in an increase in the angle of repose from 27° to 29°, while increasing weed density from 8 to 16 plants m2 caused a diminution of the angle of repose down to 28°. Increasing the density of XS and DS to 16 plants m2 caused a reduction in the maximum 1000 seed weight of maize by 40.3% and 37.4%, respectively. These weed side effects must be considered in the design of industrial equipment for seed cleaning, grading and separation. To our knowledge, this is the first study to consider the effects of weed competition on maize traits, which are important in industrial processing such as seed aeration, sifting and drying.
