Thanks for all post. I will post some picture tobacco next day

 

[NRustica]

So Jessica when are you all going to start germinating this year? Are we going to get pics on the major steps from seed to field?

 

[BarG]

I have some bezuki seed coming to me this year, and my question is this.

Should I allow all my bezuki plants to flower and pollinate or bag one , while preventing all other varietys from reaching the pollination stage? I will be growing a multiple of varietys. I appreciate your help.

 

[NRustica]

If you are growing multiple varieties it is best to bag whatever plants you are allowing to go to seed.

 

[COLIN]

I found that it best to select your best plant's and not waste time with anything inferior.

 

[JessicaNicot]

one complete rundown of what I do in the summer wasn't enough for you?! i'll think about another thread for this year tho. we haven't yet started germinating things for our nursery this year but probably in the next couple weeks we will. i'll have 250 more plots this year (and several hundreds more for the program as a whole).

I would recommend bagging a couple of plants (bagging is the only way to ensure that insects aren't bringing in pollen from other plants). the plants that you bag don't necessarily have to be the best ones but you should make sure that they don't look off type from the rest.

topping has little to do with the threat of cross pollination (as bees can travel in from 2-3 miles away) and everything to do with getting the nicotine to come up into the leaves. the nicotine is made in the roots of tobacco and topping the plant is like a traumatic injury that causes the mobilization of nicotine (a natural pesticide) into the leaves.

Intresting facts Jessica, so what you say is that , if i want lower nicotin content in the leafs , i should let the flowers stay on the plants , do you have any facts on how much nicotin content is reduced and are there some other properties can be changed by not topping the plants

Nope we find it all very fascinating.

you guys are going to love this. with a lot of searching I found a place where you can download an old book (WW Garner, The production of tobacco) that can tell you a lot of information. it may be old, but a lot of it still applies. there is a section on the effects of topping and suckering. this is the link to where the book is hosted:
http://krishikosh.egranth.ac.in/handle/1/2024773

there is also another old article on some of the other physical changes that are induced by topping: http://www.jstor.org/stable/2471838?seq=4
im not sure if you will be able to access it. if you cant then just PM me and I can download it and then email it to you.

 

[leverhead]

Thank you! I'm going to read the book tonight.

 

[jojjas]

Thanks Jessica , this is a treasure find for me , but i could only access the first link , not the second one ,
and you have made me occupied for the remains of this year
Thanks again Jessica

Thank you. I am just now trying to find info on the bezuki plant. I'm still unsure which variety I have Besuki TBN, Bezuki VBN, or Bezuki NO.

After a while searching the web I found the most info here. http://fairtradetobacco.com/threads/606-Indonesian-Tobacco-a-discussion

Several members are doing rather large seed grow outs this year, but we also want to harvest and smoke our leaves. Should we top all the plants to trigger the release of nicotine and then allow the top one or two suckers to grow and produce a seed head? Will this kill the two birds?

 

[JessicaNicot]

yes, you can top the primary head to release the nicotine and then bag a sucker. two things to keep in mind though are that suckers don't tend to produce as many flowers as the primary head (so you might have to bag more plants or multiple suckers per plant) and that it will push back the date in which the seed will be ready to harvest (which may be important if you live farther north and are prone to early frosts).

i got pelleted seed from europe a couple of years ago and there were more seeds than one in every pellet. some pellets grew five or six plants so i didn't see the reason to use pellets again if i have to thin them out anyways. the seeds were even color coded.

that is interesting because multiple seeds/plants in a single float tray cell (which is what commercial pelleted seed is used for) is very undesirable. I know that the larger US based tobacco seed companies do a good job trying to keep one seed per pellet. I don't know who you got seed from, but, just like in anything else, if you want good quality product you need to do business with a reputable dealer.

i ordered them from http://www.thetobaccoseed.com/Pelleted_Tobacco_Seeds.html. they grew well but i got more than one plant in many of the cells.

 

[JessicaNicot]

were the plants really sterile? to the best of my knowledge, male sterile tobacco varieties are a relatively new addition to tobacco breeding and it makes me highly suspect that he's reselling commercially bought seeds under another name (for example, buying commercial MS KY14 X L8 seed from Rickard and then reselling it as "Tennessee burley"). with so much seed on his site and only three pelleted varieties, it stands to reason that he's not the one sending his seeds off to be pelleted, but is purchasing pre-pelleted seed from elsewhere for resale (which im pretty sure is illegal if the variety is registered).

 

[BigBonner]

That is true but remember Rickard's , Clays and Workman are now importing most of their seeds from Argentina and other countries . What may be illegal here may be legal over there .
I see www.thetobaccoseed.com they have Turkish Basma in pelleted seeds .These are not used in the USA that I know of .

I use USA grown commercial seed and they are getting harder to find .
I also use un pelleted heirloom seeds in my float trays .
