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 attempt was made to predict the relative storability of seeds of soybean varieties (JS-335 and DSB-21) through accelerated ageing technique in comparison with that of natural ageing where both the varieties had similar initial germination (93 %). The seeds were subjected to accelerated ageing conditions at 41 oC temperature and 95 ± 5 per cent relative humidity up to 180 hours. While, for natural ageing, the seeds were packed in cloth bag with the initial moisture of 9.5 per cent and stored under ambient conditions. The experimental results revealed that with the subsequent increase in accelerated ageing duration from 24 hours onwards up to 180 hours, the seed quality parameters viz., seed germination percentage, mean germination time, seedling vigour index and dehydrogenase enzyme activity decreased significantly. While the electrical conductivity increased significantly. When the accelerated ageing results were compared with that of natural ageing, accelerated ageing for 132 hours (67 % germination) was nearly equal to nine months of natural ageing (69 % germination) in case of JS-335 whereas in DSB-21, 144 hours of accelerated ageing (70 % germination) was equal to nine months of natural ageing (70 % germination). Hence, the accelerated ageing test can be used to predict the relative storability of soybean seeds. Hence, the seed producers can take decision regarding which seed lot can be stored for longer time and which one should be immediately sold to the market without any compromise in seed quality. It also helps in taking other management decisions.
