Present laboratory experiment was conducted with an objective to know the effect of seed polymer coat-ing with Zn and Fe nanoparticles (NPs) in comparison to their bulk forms on storage potential of pigeonpea seeds. Results revealed that seed polymer coating with Zn and Fe NPs had significant effect on storability of pigeonpea seeds. Among the treatments Zn NPs at 750 ppm was found to be superior in all the studied parameters viz., seed germination (96.00, 88.67 and 81.67 %), seedling length (25.67, 22.57 and 18.60 cm), seedling dry weight (85, 81.45 and 78. 45 mg), field emergence (89.67, 77.67 and 63.33 %), seedling vigour index (2556, 2001 and 1519), alpha amylase and dehydrogenase enzymes activities at 0, 6 and 10 months, respectively and it was statistically on par with Zn NPs at 500 ppm and Fe NPs at 500 ppm. The nanoparticles treatment didn’t affect the seed moisture content (%) and insect infestation (%), however the significant difference was observed between polymer coated and uncoated seeds. In over all, the results of the study demonstrated the possibility of application Nanotechnology in Seed Science Research.

A laboratory study was undertaken to know the effect of seed polymer coating with Zn and Fe nanoparticles (NPs) at different concentration (10, 25, 50, 100, 250, 500, 750 and 1000 ppm) in pigeonpea at Department of Seed Science and Technology, UAS, Raichur. Among the treatments seed polymer coating with Zn NPs at 750 ppm recorded significantly higher seed germination (96.00 %), seedling length (26.63 cm), seedling dry weight (85.00 mg), speed of germination (32.95), field emergence (89.67 %), seedling vigour index (2556), dehydrogenase activity (0.975 OD value) and α-amylase activity (25.67 mm) and lowest abnormal seedlings (2.50 %) over their bulk forms and control followed by Fe and Zn NPs at 500 ppm. However, in contrast to beneficial effects, these NPs also shown inhibitory effect on germination and seedling growth at higher concentration (nano Zn >750 ppm and nano Fe > 500 ppm). Hence, from the results it is concluded that Zn NPs at 750 ppm can be used to enhance quality of the pigeonpea seeds.

A storage experiment was conducted to know the influence of cloth, gunny, high density polythene (HDPE), and vacuum packed bags on the seed health of chickpea for 18 months. To investigate, chickpea seeds were packed in all the bags and were kept in ambient conditions. During the storage period, there was a lot of fluctuation in moisture content of the seeds based on the relative humidity in cloth, gunny, and HDPE bags due to the pervious nature of packaging materials whereas, there was no moisture fluctuation in vacuum packed bags due to lower water vapor and oxygen transmission rate and higher thickness of polythene bag used for vacuum package. After 8 months of storage period, there was bruchids infestation to the seeds stored in cloth, gunny, and HDPE bags whereas, no bruchids infestation were seen to vacuum packed bag even after 18 months of storage but germination, root length, shoot length, seedling vigour index, seedling dry weight has reduced and mean germination time, electrical conductivity of seed leachates has increased due to seed aging.  Hence, vacuum packaging technology can be effectively used for storage of chickpea seeds for longer period without any aid of chemicals.

Background: Onion (Allium cepa L.) is a major bulbous vegetable as well as condiment of family Alliaceae grown in India, originated in Iran and Pakistan. Seed pelleting is a mechanism of applying various materials to the seed that can enhance the seed quality with respect to physiological, physical and health attributes. Seed deterioration during storage is inevitable process; however seed pelleting can reduce the rate of deterioration. The leaf powders possess antioxidant, fungicidal and insecticidal properties that helps in maintaining the seed quality during storage. Methods: The present investigation was carried out in the laboratory of Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during the seasons of 2016-17 and 2017-18. This experiment comprised of pelleted seeds with different botanicals carried out to determine the effect of seed pelleting and storage potential of pelleted seeds. Result: This experiment comprised of pelleted seeds with different botanicals. In all the treatments gum Arabica (5%) was used as the adhesive except control. The pelleted seeds with different material were stored at ambient conditions for nine months. Highest germination (81.75%), seedling length (11.20 cm), seedling dry weight (1.82 g), seedling vigour index- length (920.33), seedling vigour index- mass (148.90) and speed of germination (26.57) were observed in onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azadirechta leaf powder + clay. Among the storage periods, fresh pelleted seed (0 month) showed maximum values with respect to germination (86.50%), seedling length (13.38cm), seedling dry weight (2.02 g), seedling vigour index- length (1154.50), seedling vigour index- mass (173.52) and speed of germination (29.04).From the present studies, it can be concluded that onion seeds pelleted with Azadirechta indica leaf powder + clay and Melia azadirechta leaf powder + clay showed significant effects for enhancing seed quality during storage.

The continuous rise in global population demands more food production under limited land resources accompanied by climate change. More oversupply of quality seeds to meet ever-growing food demand is a highly challenging task. Seeds with low vigour level limit the growth and yield of crops at varied field conditions. Hence, an experiment was conducted to develop a technique for the fast and homogeneous growth of kabuli chickpea seeds. The priming treatments evaluated in the present study enhanced the various seed quality parameters of kabuli chickpea significantly when compared to control. Hydro-priming for 4 hours (at 20°C) and air drying for 72 hours showed better results compared to rest of the treatments both in fresh seeds which recorded higher first count (66.38%), germination (92.50%) root length (11.85 cm), shoot length (6.16), mean seedling length (18.01), dry seedling weight (747 mg), seedling vigour index-I (1665), higher speed of emergence (0.3992) and old seeds with higher first count (61.88%), germination (74.13%) root length (8.15 cm), shoot length (5.85 cm), mean seedling length (14.00 cm), seedling dry weight (611 mg), seedling vigour index-I (1056), higher speed of emergence (0.3814). The aged seeds have recorded 29 % increase in germination percentage in contrast to 8 percent increases in fresh seeds. Kabuli chickpea seeds could be subjected to hydropriming, an affordable, alternative, and eco-friendly technique for improving seed and seedling vigour of kabuli chickpea.

The experiment was conducted at Department of Seed Science and Technology CCS, Haryana Agriculture University, Hisar, Haryana from 2013-15 and comprised of seventeen treatment combinations of manures (viz., FYM and Vermicompost), bio-fertilizers (viz., Rhizobium and PSB) and fertilizers. The freshly harvested fenugreek seeds of all the seventeen treatment plot combinations were stored in plastic containers under ambient conditions up to a period of eighteen months. Seed quality was assessed at a regular interval of six months. A significant decline in seed quality was observed in all the nutrient combinations as the period of ageing increased. It was observed that the treatment combination of Rhizobium and PSB along with 75% Recommended Dose of Nitrogen (RDN) recorded significantly higher germination % (87.33%), seedling length (24.77 cm), dry weight (7.5 mg), vigour index-I (2163) and vigour index-II (657) followed by PSB with 100% RDN and Rhizobium with 100% RDN after eighteen months of ambient storage as compared to control. The electrical conductivity (333 µS cm-1g-1) was also recorded minimum in the treatment Rhizobium and PSB along with 75% RDN followed by PSB with 100% RDN and Rhizobium with 100% RDN after the period of ambient storage while the maximum was recorded in control. The study highlighted that the slightly reduced dose of inorganic nitrogen was best when applied in combination with bio-fertilizer (Rhizobium+PSB) for maximizing the storage potential of fenugreek seed as compared to the rest of treatments.

Rumex turcomanicus Czerep., belonging to family Polygonaceae, is one of native green vegetable in Northeast Iran. Despite the high consumption, its seed germination and dormancy aspects is inconsiderable. In order to investigate the effects of seed harvesting date on seedling emergence, vigour and growth traits of R. turcomanicus Czerep., the seeds were harvested at five different times, i.e., two weeks after fruiting (WAF), 6WAF, 8WAF (mature seeds), 2 month after seed ripening (MASR) and 4MASR, and were sowed immediately, at agricultural college of Ferdowsi university of Mashhad, Iran in 2012-2013. The results was showed that the highest and lowest of seedling emergence percentage, seedling emergence rate, seedling vigour index, seedling fresh and dry weight, seedling root and shoot length, total seedling length and %final normal seedling (%FNS) was obtained in the seeds which were sowed 4MASR and 2WAF, respectively. Maximum and minimum of mean emergence time (MET) was observed in the seeds which were sowed 2WAF and 4MASR, respectively. Relationship between %FNS and MET and between %FNS and emergence percentage was highly significantly negative (-0.961) and positive (+0.962), respectively. Based on the results of this experiment, it seems that the problem of germination in most of the Rumex turcomanicus Czerep. seeds, is probably due to a kind of morphological dormancy, which is remained in most of the fresh seeds (collected 2WAF), and eliminated in the mature seeds (collected 2MASR). Also dry seed storage of the mature seeds for two months was improved seedling emergence and vigour, significantly.

Abstract An experiment was carried out in the Laboratory of Seed Technology-College of Agricultural Engineering Sciences - University of Baghdad – Iraq, to studying the stimulation of maize seeds by soaking with selenium and chitosan to improve the vigour and viability of seeds. By using factorial experiment according to the Complete Random Design (CRD) with three replications. The seeds of two synthetic cultivars of maize (Baghdad 3 and Buhoth 5018) were soaked in selenium solutions at two concentrations (2 and 5 mg L-1), and chitosan (100 and 500 mg L-1) for 10 hours, as well as the two control treatments, which were dried seeds (without soaking) and the seeds soaked in distilled water. Results are shown that low concentration of 2 mg L-1 give highest mean were recorded in the percentage of germination in the first and final counts, the mean time germination, length of root and the plumule, the seedling vigour index, germination speed, and dry weight of the seedling. Seeds soaking with the solutions containing chitosan at both concentrations did not give significant results compared to the selenium treatments, both cultivars differed significantly in some germination characteristics and the vigour and viability of the seed: (length of root and the plumule, dry weight of the seedling). The results also showed a significant effect of the interaction between seed soaking treatments and cultivar on all studied traits. We conclude from this study that treatments of stimulating seeds by soaking them with distilled water and solutions of selenium and chitosan positively affected germination and its characteristics, so we recommend using low concentrations of selenium and chitosan to improve seed germination, vigour, and viability of the seedling.
