Effect of dolomite, horse manure and NPK application on plant growth and yield of Cauliflower and its residue effect on Snap bean cultivation

Liming and fertilizers were reported to affect significantly the plant growth. The goal of this experiment was to study effect of dolomite, horse manure and NPK fertilizer on cauliflower and its residue on snap bean yield. Research activities had been carried out at Experimental Garden of Indonesian Vegetable Research Institute (IVEGRI) in Lembang - Bandung, West Java. A Split-split Plot Design with three replications was set up in the field. The main plots were dosage of dolomite, viz. 0 and 3 t/ha, the sub plots were dosage of horse manure, viz. 0, 15 and 30 t/ha, and the sub-sub plots were dosage of NPK fertilizer, viz. 600 and 1200 kg/ha. The results showed that horse manure and dolomite significantly affect plant diameter and yield of cauliflower, but not NPK. The best yield without dolomite could be reach by 30 t/ha horse manure plus 600 kg/ha NPK fertilizer, but with dolomite 3 t/ha the best yield could be reach by 15 t/ha horse manure plus 600 kg/ha NPK fertilizer. Dolomite could reduce a half of horse manure application. Dolomite residue also gave good effect on snap bean yield.
