Studies on Application of Organic-Compound Fertilizer on Hilly Mixed Sward Ⅱ. Effect of organic-compound fertilizer application on qualities of grasses

With a purpose of finding out the effects of magnesium and boron enriched organic-compound fertilizer application on qualities of grasses on the hilly pasture, a field experiment was arranged with five different treatments as a randomized block design and lasted from September, 1984 to the end of growing season in 1986. The results obtained are summarized as follows: 1. Mean chemical components except NFE of grasses at the plots with organic-compound fertilizer application were appeared to contain slightly high comparing to single dressing. 2. Production of DCP with organic-compound fertilizer (1,170.2 kg/ha) was significanty increased by 20% comparing to single dressing (975.7 kg/ha) in the conventional fertilization level (p<0.05), but it was not significantly different between them in the low dressing level. 3. Production of energies (TDN, StE and NEL) with organic-compound fertilizer of low and conventional dressing level were appeared to increase by 10 and 13 to 15% than those of single dressing of the same levels, respectively. But it was not significant difference. 4. Like single dressing nutrient productions with organic-compound fertilizer were appeared significantly high due to increasing of dressing gradually (P<0.05-0.01) 5. Mineral contents of P and Mg at the plots with organic-compound fertilizer were a little higher, on the other hand, K, C/P and K/Ca + Mg equivalent ratio were slightly lower than those of single dressing, but the content of Ca tended to similar between them.
