Analysis of variance revealed that the differences among 12treatments were significant for seedling characters and field parameters. Mean value is defined by the ratio of the sum of observations to the total number of observations. It avoids variation of over all data and depends only on extreme values. The data is presented in field parameters (Table 1a and 1b, Fig 1) and seedling characters (Table 2, Fig 2) which show the mean performance of 12 treatments and is used to check whether they are statistically at par by subtracting the CD value from the highest value of a particular set of observations.
Analysis of variance for field revealed that mean sum of squares due to seed priming treatments were highly significant at @ 5% and 1% level of significance for 2 parameters and 5% significant for all other characters under study indicating presence of good amount of variability among the treatments for all parameters of (Fig 1 and Fig 2) used in the study. This indicated the ample scope of seed priming treatments in kodo millet. Replications were non- significant for all parameters except panicle length indicating good homogeneity among replications. This suggested, an ample scope to identify suitable seed priming method to improve seed quality and yield attributing traits of Kodo millet.
Field emergence
The mean performance of field emergence ranged from 79.160% to 98.610% with mean value of 86.110% and found significantly maximum of 98.610% of T
4- magnetic @ 200 mT and T
5- magnetic @ 400 mT was found to be at par value. After post-harvest conditioning seeds are more vigorous and less sensitive to unfavourable environmental conditions during field emergence given by
(Rochalska et al., 2005). Similar findings were reported by
Rajesh (2011) in finger millet.

The mean performance of plant height ranged from (259.033 to 358.600 cm) and (358.433 to 437.667 cm) with mean value of 310.867 cm and 393.567 cm significantly maximum, highest plant height was recorded (358.600 and 437.667 cm) by T
5 magnetic field @ 400 mT. The results are of findings of
Kalaraju et al., (2009) in pearl millet found taller plants at harvest stage. Similar results are in conformity with the findings of
Makkhanlal et al., (2007) and
Michael et al., (2016) in pearl millet. The enhancement of most vegetative characteristics of a plant can be explained by magnetic seed treatment that the groups of molecules become small in size compared to their pre-magnetization status. This allows for good and rapid transfer through root cells and come up with enhanced mineral uptake.

(Nandini et al., (2019).

Naidu and Rao (1958), Narasimha
Rao et al., (1963); Rajesh (2011) in finger millet.

Elangovan et al., (2013) and similar results were reported by
Dossou-Aminon et al., (2015) and reports of
Akatwijuka et al., (2016) in millets.
Peduncle length per plant
It was presented the mean performance of peduncle length per plant ranged from 23.3 cm to 32.933 cm with mean value of 27.433 cm. Significantly maximum peduncle length per plant (32.933 cm) highest value was recorded by T
5 - Magnetic field @ 400 mT. Similar reports by

It was presented the mean performance of grain yield per plant ranged from 27.9 gm to 45.867 gm with mean value of 35.933 gm. Significantly maximum Grain yield per plant (45.867 gm) highest value was recorded by T
5 - Magnetic field @ 400 mT and T
0 - control (27.9 gm) was recorded and found to be lowest value. Cultivation of plants with desirable density has positive effect on crop yield components, so that the suitable yield was achieved by superlative plant density by
(Ullah et al., 2005).

It was presented the mean performance of seed yield per kg/ha ranged from 100.44 kg to 165.12 kg with mean value of 129.36 kg. Significantly maximum seed yield per kg/ha (165.12 kg) highest value was recorded by T
5 - Magnetic field @ 400 mT. The results were observed by Moobe,
Martha et al., (2014) on growth and grain yield in finger millet. But Morphological differences in plants of Barley grown from treated seed were significantly lower than those of barlev grown from untreated seed. The decrease in yield might be related to the lack of sufficient soil moisture during the later stages of development of the early maturing plants grown from treated seed is indicated by the lower test weight of the crop produced by the treated seed.
Germination %
It was presented the mean performance of germination % ranged from 80.25% to 98.5% with mean value of 90.25%. Significantly maximum percentage of Germination % (98.5%) highest value was recorded by T

0 - Control (9.733 cm) and found to be lowest value. Seed priming showed significantly good results over control for time taken to germination % root length and shoot length
(Afzal et al., 2009) and the potential to improve the early seedling growth and nutrient contents of seedlings
(Harshan et al., 2011) in Barley. Magnetic field treatments were used in agriculture to improve the germination and growth seedling. In this research, general results showed that the magnetically treated sorghum seed gave the significant effect on all germination and growth seedling parameters studied, where the best period to expose the seeds recorded in 6 hour treated seeds in all measurements parameters in comparision with untreated seed, except root length.

5 - magnetic field @400 mT and T
0 - control (0.00329 gm) and found to be lowest value. It might also due to result of better activity of mitochondrial enzymes accompanied by an increase of the oxygen consumption. The similar results were observed by
Mahmoudi et al., (2012); Piri et al., (2009). An increase in the wet and dry weights of the treated plants was recorded with magnetized water was reported.

(Afzal et al., 2009). Similar results of agro-morphological characters in finger millet observed by
Patil et al., (2019).
