Abstract

To evaluate fertilization with organic compost associated to supermagro biofertilizer leaf application on growth and development of coffee (Coffea arabica L. cultivar Topázio MG-1190), a greenhouse study carried out at the Federal University of Lavras, from March 15 to October 4 of 2003. A randomized complete block design in factorial arrangement (5 x 5 + 3 adictional factors) was used with four replications, using one plant per plot. First factor used was organic compound rate/pot (110, 330, 550, 770 and 990 g). The second factor was supermagro applied monthly to leaf at 0%, 3%, 6%, 12% and 24% concentration. Additional treatments were organic fertilizer, organic + mineral and mineral fertilizer soil application. Characteristics evaluated were plant stalk node number, leaf area (cm2), leaf number, leaf dry weight, aerial part plant dry weight, total plant dry weight. Significant interaction occurred with numbers of lateral branch, leaf, leaf dry weight, aerial part dry matter and total plant dry weight. The best plant development was from 702 to 770g rating of the compost/pot plus supermagro application from 14.6% to 16.2% rating.
