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.

The seeds must be viable and non-dormant for the efficient cultivation of the species of medicinal plants. The seeds of Solanum nigrum possess primary dormancy, which restricts germination. Hence, a laboratory experiment was conducted during 2019 in the Department of Seed Science and Technology, Agricultural College and Research Institute, Madurai, Tamil Nadu. The S. nigrum seeds were primed by soaking in different chemicals viz.,GA3 100ppm, Thiourea1%, KNO3 0.5%, Succinic acid 100 ppm, Ascorbic acid 100 ppm, hydro and dry control with soaking durations of 12h and seeds were dried under shade to bring back to their original moisture content and used for assessing the seed quality studies. The results revealed that among the different priming treatments Thiourea 1% recorded higher seed quality parameters viz, speed of germination (5.6), germination (88 %), seedling length (5.92 cm) and vigour index (520) and the enzyme activity of dehydrogenase (0.072 OD value) and lower values of electrical conductivity( 0.027 dsm-1),  amino acids (0.119 ?gg-1 ) and sugars ( 0.175 ?gg-1 ). Hence it could be recommended as pre-sowingg seed priming treatment in S. nigrum.

Hydration And Dehydration

Background: Seed priming is controlled hydration and dehydration that results in improved seed quality and yield. However, hydration-dehydration of fresh seeds would result in soaking injury especially in legumes. The disadvantage reported in pulses can overcome through pre-conditioning of seeds which allows the seeds to slow hydration and prevent the soaking injury. The conditioning of seeds in large scale is tedious and skill oriented. To overcome this problem, an innovative seed priming technology is essential for pulses to enhance the seed germination, vigour and seed yield. Methods: Experiment was carried out at National Pulses Research Centre, Vamban during 2016-18. Seed priming technology was developed by using marginal vigour lot of blackgram. The marginal vigour seeds were packed in gunny bag up to 3/4th level and soaked in water for 2 h and 4 h and incubated for 2 h, 4 h and 6 h. After the incubation period, seeds were dried back to original moisture content (9.0%) and seed quality parameters were analyzed. The best performing organic priming concentrations under laboratory were forwarded to field trial and yield parameters were assessed. Result: Marginal vigour lot of blackgram seeds packed in gunny bag and soaked in seaweed extract @ 0.4% for 2 h and incubated for 4 h significantly increased the seed quality parameters. Among the various organic priming, marginal vigour lot of blackgram seeds packed in gunny bag and soaked in seaweed extract @ 0.4% for 2 h and incubated for 4 h significantly increased the seed quality parameters and yield over hydro priming and control.

The experiment was conducted to find out the effect of variety, nitrogen level and harvesting time on yield and seed quality of barley. The treatments used in the experiment consisted of two varieties viz. BARI Barley 4 and BARI Barley 5, three harvesting time viz. 35, 40 and 45 Days after Anthesis (DAA) and nitrogen levels viz. 0, 70, 85 and 100 kg N ha-1 . The experiment was laid out in a spilt- spilt-plot design with three replications assigning the variety to the main plot, harvesting time to the sub-plots and nitrogen level to the sub-sub plots. Variety had significant effects on the all yield attributes except fertile seeds spike-1 . Seed quality parameters viz. normal seeds spike-1 , deformed seeds spike-1 , germination (%) and vigour index were statistically significant. The variety BARI Barley 5 produced higher grain yield and seed quality than BARI Barley 4. Grain yield from BARI Barley 5 and BARI Barley 4 were 4.59 t ha-1 and 4.24 t ha-1 , respectively. Significantly, the highest 1000-seed weight (46.90 g) was produced by BARI Barley 5 than (37.90 g) BARI Barley 4. The result revealed that harvesting time had significant effect on yield and yield attributes and seed quality parameters. Seed yield was highest (4.65 t ha-1 ) when the crop harvested at 40 DAA and it was increased linearly from 35 DAA. Maximum quality seed and 1000-seed weight (43.20 g) was obtained when the crop harvested at 40 DAA. All the yields, yield attributes and seed quality parameters were significantly influenced by nitrogen levels. The highest grain yield (5.14 t ha-1 ) was obtained when BARI Barley 5 variety was fertilized by 100 kg N ha-1 and the lowest (3.14 t ha-1 ) was obtained from control treatments. Normal seeds spike-1 , vigour index, germination (%) were better at 85 kg N ha-1 in variety of BARI Barley 5 than BARI Barley 4. So it can be concluded that BARI Barley 5 showed better result when fertilized with 100 kg N ha-1 and harvested at 40 DAA for getting maximum yield and 85 kg N ha-1 and harvested at 40 DAA for getting better quality seed.

Priming Technique

Summary A useful approach for improving seed germination and seedling growth is a seed priming technique. Application of the priming technique enhances water absorption, causing activation of metabolic activities in the seed. The objective of this study was to evaluate the effect of seed priming on germination parameters of safflower and to compare different priming techniques: priming by soaking and priming on filter paper. The priming treatments included hydropriming (distilled water) and osmopriming with 0.1% and 0.5% solutions of KNO3 for 8 and 16 hours. The experiment revealed significant difference between the priming treatments and the control. The highest germination (89.50%) was recorded within the priming treatments by soaking in the solution of 0.1% KNO3 and priming on filter paper moistened with 0.5% KNO3 for 8 hours. Considering germination index, mean germination time and time to 50% germination, the best results were obtained within hydropriming on filter paper for 16 hours. This study has shown that the priming techniques significantly improved germination parameters of safflower. Although priming on filter paper showed better results, the soaking technique – due to its simplicity, low cost and easiness of application – can be successfully used to improve germination parameters of safflower and increase the number of plants per unit of area and thus increase the seed yield per acreage.
