Résumé:
The diversified and sustainable production of agricultural products with emphasis on
vegetables has become in recent years a great alternative for those who want to
serve a demanding market. The objective of the study was to evaluate the economic
viability of lettuce and coriander cultivars in intercropping systems, due to different
types of organic mineral fertilizer.
The experiment was conducted under field conditions in the Science and Technology
Center Agrifood (CCTA) of the Federal University of Campina Grande (UFCG),
municipality of Pombal PB. The experimental design was a randomized blocks
treatments were made up of types of fertilizers and farming systems in a factorial 3x2
being the first factor three ferti lizations: 1 = Fertilization with Animal Waste (manure
Bovine); 2 = Mineral Fertilization; 3 = Incorporation of spontaneous vegetation and
the second factor of two farming systems: 1 consortium and 2 monoculture. In the
different systems were measured tota l operating cost (TOC), labor cost, depreciation,
efficient use of land (UET), gross income, net income, rate of return and profitability
index and cost time machine, implements and operations . The BOTs values of
intercropping systems were calculated mo nth prices June 2016. The biggest COT
was obtained in lettuce monoculture with fertilizer to the base of manure with a net
income R $ 73,706.09 ha 1. So the best result was accomplished with the planting
lettuce with coriander when fertilized will base man ure despite not having the highest
net income (68141.12 ha 1), but stood out because of a better UET (1.69) and the
diversification of products.
