開墾地에 있어서 마그네슘, 붕소 및 아연 施用이 참깨 諸形質變化에 미치는 影響

This study was conducted to increase the seed yield and to find the interaction of several characters of sesame on the reclaimed upland by application of minor nutrient which were boron, magnesium and zinc. A result of testing of boron and magnesium were effective relatively. Application of boron and magnesium were increased the dry stem wt. of upper capsule setting position, Specially dual application of boron and magnesium were remarkable. Dry stem wt. affected on seed increasing of lower and middle capsule setting part. Capsule no. per plant was showed higher degree in dual B+Mg than each application. Capsule no. affected on increasing of dry stem wt. as well as seed yield also. Capsule no. of lower and upper capsule setting part indicated relation with seed yield, 1000 grains weight. This result showed increasing tendency of upper capsule setting part in B+Mg+Zn application. The products of seed yield indicated the increasing of estimate production at the highest 21% in dual Mg+B, 17% of dual B+Zn+Mg secondly, 12% of single boron application thirdly.
