An experiment was conducted to investigate the influence of fungicides and packaging materials on longevity of chilli seed (variety: RCH-1). The seeds were treated with 15 fungicides and were kept in three containers viz. Metal box, Cloth bag and Plastic zipling bag up to 12 months under ambient conditions in seed pathology laboratory of Department of Seed Science & Technology, CCSHAU, Hisar, India. The samples were drawn at quaterly intervals for ascertaining the seed quality parameters. The seeds treated with flusilazole (2 g kg-1 seed) and stored in metal-box were found better for maintenance of higher seed quality parameters [germination, root length, shoot length, mean seedling dry weight, vigour indices] during the study period. The study suggested that use of appropriate packaging material and seed treatment could be useful to prolong the storage life of chilli seeds.

Good storage is the basic requirement in seed production programme as maintenance of high seed viability and vigour from harvest to planting is of utmost importance in a seed production programme. Therefore, inexpensive, simple and practicable technology to prolong the shelf life of seeds under ambient condition is immensely needed. Hence, an experiment was carried out to study the effect of seed treatment with neem oil, nimbicidin, emamectin benzoate 5 SG, deltamethrin 2.8 EC, novuluron EC on black gram seed quality under ambient conditions. The seeds without any seed treatment were included as control. The treated and untreated seeds were stored in cloth bag and polylined cloth bag. The results revealed that, botanicals and emamectin benzoate seed treatments were significantly superior in controlling the storage insect and maintaining higher seed quality up to 10 months of storage when compared to control. Among the chemicals, the emamectin benzoate 5 SG @ 40 mg kg-1 of seed found better by recording significantly higher germination percentage (80.28), vigour index I (2124) and dry weight of seedlings (43.14 mg) and lower electrical conductivity (0.939 dSm-1) and seed damage (0.00 %) compared to control (78.78%, 2012, 38.90 mg, 0.942 dSm-1, respectively) at the end of 10th month of storage. The emamectin benzoate 5 SG and nimbicidintreated seeds stored in polylined cloth bags were considered as effective seed storage management approach in blackgram.

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 present investigation on effect of nitrogen [N0 (Control), N1 (50 kg N/ha), N2 (100 kg N/ha), and N3 (150 kg N/ ha)] and plant growth regulators [G0 (Control), G1 (50 ppm GA3), G2 (50 ppm NAA) and G3 (500 ppm Cycocel)] on seed yield per plant and seed quality parameters in brinjal (Solanum melongena L.) cv. GJB 3 was carried out at the Instructional Farm, Department of Agronomy, Junagadh Agricultural University, Junagadh during kharif 2015-16. The experiment was laid out in field as per randomized block design (Factorial) with three replications. The seed harvested from 16 different treatments combinations replicated thrice from the field were analyzed in the laboratory following completely randomized design (factorial) for various seed quality parameters. Application of nitrogen @ 150 kg N/ha recorded significantly (P<0.05) highest seed yield per plant, shoot fresh weight, root dry weight, shoot dry weight and vigour index – 2 (mass), while application of 100 kg N/ha resulted in significantly (P<0.05) highest germination percentage, root length, shoot length, root fresh weight and vigour index – 1 (length). Application of GA3 at 50 ppm recorded significantly the highest seed yield per plant, germination percentage, root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight, vigour index – 1 (length) and vigour index – 2 (mass). Among the 16 different treatment combinations, nitrogen @ 150 kg/ha and GA3 50 ppm noted the maximum seed yield per plant, shoot dry weight and vigour index – 2 (mass), while significantly the maxi-mum germination percentage, root length, shoot length, root fresh weight, shoot fresh weight and vigour index – 1 (length) were registered in treatment combination nitrogen 100 kg N/ha and GA3 @ 50 ppm. Therefore, it is advised that application of 100-150 kg of N/ha as a nitrogenous fertilizer and spray GA3 @ 50 ppm (G1) at 45 days after transplanting helps in increasing the seed yield per plant and seed quality parameters in brinjal seed production.

An experiment was conducted to investigate the influence of packaging materials and seed treatments on storability of cluster bean under ambient conditions of Bengaluru. The experiment consisted of six treatments viz. control (T1), bavistin @ 2 g kg-1 (T2), spinosad @ 0.04 ml/kg (T3), neem leaf powder @ 1:20 ratio (T4), Acorus calamus@ 10 g kg-1 (T5) and cow dung powder @ 10 g kg-1 (T6) and three packaging materials viz., cloth bag (C1) super grain bag (C2) and poly lined cloth bag (C3). Treated seed samples were stored in three containers under ambient storage conditions up to the duration of which seeds maintain minimum seed certification standards and samples were drawn at bimonthly intervals for ascertaining the seed quality parameters. The study suggested that seed treat-ment could be useful to prolong the storage life of cluster bean seeds. The seeds treated with spinosad (0.04 ml/kg) and stored in super-grain bag were better for maintenance of higher seed quality parameters [germination (80.00%), root length (11.70 cm), shoot length (13.60 cm), mean seedling dry weight (152 mg), seedling vigour index I and II (2024&12140) and TDH activity (1.224) with low electrical conductivity (0.368 dSm-1)] up to 18 months under ambient conditions of Bengaluru (room temperature). Super-grain bag proved to be better storage container with higher seed quality attributes viz., germination (72.38 %), seedling vigour index-I (1726), total dehydrogenase activity (1.201) and other seed quality parameters compared to cloth bag. The study suggested that use of appropriate packaging material and seed treatment could be useful to prolong the storage life of cluster bean seeds.

This research was performed for a period of three years to determine the effect of natural seed ageing on different physiological and biochemical changes in three extensively cultivated onion cultivars in Northern India. Seed storage studies showed that germination percent, seed viability and other seed quality parameters decreased significantly with increasing storage time. The onion seed can be stored for a maximum period of one year under ambient conditions to maintain required germination percentage (>70%). Overall, Hisar Onion-4 stored better when compared to Hisar Onion-3 and Hisar-2. As the ageing progressed the seed antioxidants, namely superoxide dismutase (SOD), catalase (CAT), dehydrogenase (DHA) and peroxidase (POD) decreased significantly (p < 0.05) in all cultivars whereas, the electrical conductivity (EC) of seed leachates increased significantly. Under the field conditions, seedling establishment percent (SE) onion seed was positively correlated (R2 = 0.98; p < 0.05) with germination percent (GP). Overall, more than one year period of seed storage was associated with poor germination and seedling establishment potential in onion.

Soybean seed is classified as “poor storer” as it loses viability under warm and humid conditions and is invaded by storage fungi. The seed of soybean variety PS 1347, obtained from Breeder Seed Production Centre, G. B. Pant University of Agriculture and Technology, Pantnagar was used for storage study. Root length (cm), shoot length (cm), seedling fresh weight (g) and seedling dry weight (g) decreases with the increase in seed storage periods. Out of all chemical treatments, Flowable thiram @ 2.4 ml/kg (T2) and Polymer + vitavax 200 @ 2g/kg seed (T5) were found effective to maintain Seedling root length, shoot length, seedling fresh weight and seedling dry weight by producing vigorous seedlings. Seeds stored in cloth bags exhibited higher seed infection than in seed stored in polythene bags, irrespective of seed treatment and period of storage. Treatment T4 (Vitavax 200 @ 2 g/kg seed)and T5(Polymer + vitavax 200 @ 2 g/kg seed) exhibited minimum percent seed infection of Aspergillus flavus. Cloth bag was not found safe for longer storage of soybean seeds under ambient storage at Pantnagar.

The study revealed that China aster seeds lose viability quickly if stored under ambient conditions. At the end of 12th months, seeds stored at refrigerated condition (5-70C) still maintained high seed germination (64.00%) at field condition well above the minimum seed certification standards. However, in case of ambient storage very drastic reduction in seed germination was observed. It was 32.43 % for first months and reduced to 14.95 % for second month by declining 53.90% as compared to first month and thereafter no germination was recorded at field condition. Results from the interaction effect indicated that previously stored seeds of China aster for six months in aluminium foil and kept under refrigerated condition recorded higher seed quality parameters viz. percent seed germination at field (92.67 and 72.00%), percent survival of seedlings (89.33 and 70.67%), height of seedling (11.53 and 8.60 cm), shoot length (7.00 and 5.10 cm), root length (4.53 and 3.50 cm), shoot weight (0.42 and 0.33 g), root weight (0.040 and 0.027 g), root:shoot ratio (0.095 and 0.082) and percent seed germination at laboratory (97.33 and 76.00%) for first and sixth month, respectively.
