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.

Field experiments were conducted with four levels of seed priming including control and two varieties of pigeon pea at ICAR-Indian Institute of Seed Science, Mau during three consecutive years (2011-12 to 2013-14). One-year-old seeds of pigeon pea varieties (Bahar and Malviya-13) were primed with growth regulator (100 ppm GA3), in-organic salt (0.2% KNO3) and tap water (sanitized) separately for 06 hrs. and sown in field under RBD with 03 replications. Observations were recorded on seed quality parameters, biochemical attributes including nitrate assimilatory enzymes and activities of anti-oxidant enzymes during seedling stage. Seed quality parameters including germination, seedling growth and vigor indices were significantly enhanced through seed priming with GA3 followed by KNO3 and tap water over unprimed control. Biochemical attributes viz; chlorophyll a andb contents, were more influenced with GA3 priming followed by KNO3 and tap water whereas the proline accumulation was reduced with priming treatments and maximum reduction was noted with GA3 followed by KNO3 and tap water. Enhancement in nitrate assimilatory enzymes including nitrate and nitrite reductase activities was more with KNO3 priming followed by GA3 and tap water. Anti-oxidant enzymes activities including Catalase, Peroxidase and Super Oxide Dismutase were also increased significantly by KNO3 priming followed by GA3 and tap water over unprimed control.

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.

Background: Seed priming technique involves soaking of seeds in priming agent to a point where germination related metabolic activities occur in the seeds followed by drying of imbibed seeds to original moisture to prevent the radical protrusion and facilitate storage of primed seed. Draining of priming agent and drying of large quantity of primed seeds is a laborious and time consuming process. The current study was aimed to standardize automation of seed priming process by utilizing house-hold top loading washing machine. Methods: The top loading washing machine referred to as Seed Priming Cabinet, contained a priming drum with provision for draining water. On completion of the soaking period, the ‘SPIN’ button was pressed by setting the duration of spin drying (1, 2, 3, 4 and 5 min.). Then the seeds were removed from the drum of priming cabinet and subjected to shade drying so as to reach the original moisture content and evaluated for seed quality parameters. Result: The blackgram seed subjected to conventional hydropriming was compared with automatic seed priming for 1, 2, 3, 4 and 5 min. and observed that hydropriming and spin drying for 3 min. was found to be optimum and the per cent increase in germination recorded over control was 18.0 per cent thus suggesting that automation of seed priming technology can be recommended for enhanced seed vigour and crop productivity of blackgram.
