Effect of boron on seed quality of peanut Tainan 9

Keerati-Kasikorn, P., Panya, P., Plaskett, D., Bell, R.W., Hiranburana, N., Laohasiriwong, S. and Loneragan, J.F. (1988) Effect of boron on seed quality of peanut Tainan 9. In: Proceedings of the 26th Annual Kasetsart University Conference, Plant Science, 3 - 5 February, Kasetsart, Bangkok.



Boron deficiency of peanut in Khan Kaen province was wide spread. The experiments were set up to investigate the effect of boron on the yield of peanut Tainan 9 and its seed quality with respect to the incident of hollow heart in the seed, seed germination and vigor. Application of boron at the rate of 0.25 kgB/ha significantly increased pod and seed yield per plant. The hollow heart incident due to boron deficiency of the large and the small seeds (a seive with a hole of 0.7 cm in diameter was used to separate the size) were decreased significantly when boron was applied at the rate of 0.5 and 1 kgB/ha respectively. However, boron applied at such rate could only reduce the hollow heart incident of the large seed group to be less than 20Jo. The application of boron omitted fertilizers to peanut growing on the boron deficient soil accentuated the magnitude of hollow heart incident of the seed. The large seed had less degree of hollow heart incident than the small one. Two-seeded pod and one-seeded pod were not significantly different in term of the production of seed with hollow heart incident. Lower boron seed (8.4-9.2 ugB/g) had less germination percentage, and vigor than higher boron one (11.1 ugB/ g). Germination percentage of seed was not affected by external application of boron.
