Doses of organic residues in soil mulch influence productivity and profitability of Peruvian carrot
ABSTRACT Organic residue addition to soil is a recommended practice for arracacia production. This study was aimed at analyzing the agroeconomic productivity of arracacia cultivated with different doses (0, 5, 10, 15, and 20 Mg ha−1) and residue types in broiler manure (sawdust and rice hu...

| Sumario: | ABSTRACT Organic residue addition to soil is a recommended practice for arracacia production. This study was aimed at analyzing the agroeconomic productivity of arracacia cultivated with different doses (0, 5, 10, 15, and 20 Mg ha−1) and residue types in broiler manure (sawdust and rice hulls). From the arrangement in a 5 × 2 factorial scheme, ten treatments resulted, in a randomized complete block design with four replications. The highest leaf mass production was obtained with 11,2 Mg ha−1 of broiler manure. The use of broiler manure containing sawdust at 16 Mg ha−1 resulted in the highest shoot and root productivities. The maximum numbers of shoots were 649.500 ha−1 and 651.560 ha−1, with 12,48 Mg ha−1 and 9,20 Mg ha−1 of broiler manure containing sawdust and rice hulls, respectively. The maximum number of marketable roots was obtained by using 11,77 Mg ha−1 and 12,21 Mg ha−1 of broiler manure containing sawdust and rice hulls, respectively. The costs per hectare varied by R$ 3.233,55 between the lowest and highest costs. It was concluded that the highest productivity of marketable arracacia roots was obtained with 16 Mg ha−1 of broiler manure containing sawdust. The highest gross and net incomes were obtained with 15 Mg ha−1 of broiler manure containing sawdust. |
