It is presented to estimate neutron yield from p^7Li, p^9Be and p^<10>B fusion reaction plasma, which has not been estimated with respect to the neutron generation. Neutron yield value from the p^7Li plasma at T_i =200keV and T_e = 0.12keV is 2.94 x l0^<-2>, which is mainly contributed from ^7Li (p, n) ^7Be and ^7Li - ^7Li multi-channel reaction. The same from the p^<10>B plasma at T_e = 350keV and T_i = 0.04keV is 2.74 X 10^<-4> mainly from ^<10>B (d, n) ^<11>C reaction by deuterum as an impurity of the fusion fuel of proton. In the case of the p^9Be plasma at T_i = 95keV, yield values are 4.11 X 10^<-6> and 6.91 X 10^<-4> at the other plasma conditions of T_e = 0.05keV and T_e = 95keV, respectively, and are comparatively similar to the ones from the p^<11>B plasma at T_i = 200keV. It can be physically understood, by the both values of the reaction cross section and the lower energy of generated particles of ^4He and deuterum from the p^9Be main reaction, that the neutron yields of p^9Be reaction become almost equivalent to the ones from the p^<11>B reaction.
