The current paper has presented the data on organization of primary seed production spring barley. There been considered concept “primary” production, which is based individual-family method selecting families with a two-year estimation progeny, allows preserving and identifying varieties according to most important economic biological traits properties. emphasized an importance using qualified...

A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...

In addition, he saw algebraic 5. Idem, p. 230 6. Knowing via minimal or simplest cause would have been better stil...

Dominions, in the sense of Isbell, are investigated in the context of decomposable varieties of groups. An upper and lower bound for dominions in such a variety is given in terms of the two varietal factors, and the internal structure of the group being analyzed. Finally, the following result is established: If a variety N has instances of nontrivial dominions, then for any proper subvariety Q ...
