Pruning and fertilization practices plays an important role in coffee plantation, used to maintain soil quality and coffee productivity. However, the impact of pruning and fertilization practices on soil microbial activity under coffee-based agroforestry are poorly understood. The aimed of this study was to analyze the response of soil microbial properties (i.e., soil microbial biomass C (SMBC) and soil respiration rates (SR)) to pruning and fertilization management in coffee-based agroforestry in UB (Universitas Brawijaya) Forest. A split-plot design with eight treatments and three replications were used in this experiment. The main-plot factor consisted of two types of pruning (Pruning and Bending), and the sub-plot factor consisted of four types of fertilization (i.e., no fertilizer (NF), 100% chicken manure (MN), 50% chicken manure + 50% NPK-inorganic (MN+NPK), and 100% NPKinorganic (NPK)). The result showed that there was a significantly different (p<0.05) in the soil microbial biomass C and soil respiration after the application of fertilizer. The addition of chicken manure (MN and MN+NPK treatment) could enhance the soil microbial biomass and soil respiration, compared to the NF treatment under different pruning practices. The level of soil pH in MN were highest and significantly different with NPK treatment, showed that the application of chicken manure had a potential to neutralize the soil acidity. Metabolic quotient (qCO 2 ) showed highest in the NF treatment as compared to the other treatments. The soil respiration had positive correlation (p<0.05) with SMBC, while SMBC had negative correlation (p<0.01) with qCO 2 .

The increase of great chilli concumption may increase great chilli cultivation area in degraded land. To reach high crop production, foliar fertilizer enriched by hormone can be used to improve soil fertility, plant growth and production in great chilli cultivation. This study aimed to determine the effect of addition NAA on soil properties, growth, leaf nutrient content and yield on great chilli. This research took place in Agro Techo Park, Jatikerto Village, Kromengan District, Malang Regency. The study was designed by using a factorial randomized block design with 2 factors that consisted of NAA doses (P1: 0; P2: 75% NAA; P3: 100% NAA; and P4: 125% NAA) and interval application (I1: 14 days and I2: 18 days); each combination treatment was repeated three times. The result showed that difference doses of NAA on foliar fertilizer gave impact on plant growth (i.e height, number of leaf, number of flower per plant, number of fruit per plant) and crop yield of great chilli. Various doses NAA on foliar fertilizer had affected to soil chemical properties (i.e pH, Organic-C, total N, Available P, exchangeable-K and nutrient content (i.e N, P, K) in the leaf of great chilli.
