Resumo:
Coriander (Coriandrum sativum L.) is an annual herbaceous vegetable crop
with average height 10-20 cm plant-1, depending on the soil conditions that are being
grown, cultivar and fertilization. Its cultivation is mainly geared to meet the demand for
fresh consumption stems and condiments industries. In this sense the research aimed to
evaluate the jitirana (Merremia aegyptia), silk-flower (Calotropis procera) and kills
pasture (Senna uniflora) as a source of green manure on agroeconomic performance of
cilantro. The experiment was conducted at the Experimental Farm Rafael Fernandes,
located in the district of Alagoinha, rural area of Mossoró-RN, in the period from July-
September 2014. The experimental design was complete randomized block with treatments
arranged in a factorial 4 x 3, with 3 repetitions. Treatments included a combination of four
amounts of wild species (0,4; 0,8; 1,2 e 1,6 kg/m2) and the second factor, corresponding to
three types of spontaneous species (jitirana, silk-flower and bush-pasture). Each plot
consisted of twelve rows of plants spaced 0,1 mx 0,05 m, with 05 plants pit-1. Ten days
after germination thinning took place thirty-three days after the planting to harvest was
performed. The characteristics evaluated were: plant height, number of stems per plant,
fresh coriander mass, dry mass and number of bunches cilantro coriander, economic
parameters were: gross income, net income, rate of return per dollar invested and
profitability index. Plant height in relation to the types of green manures, a difference was
observed in relation to the jitirana-flowered silk-flower and bush-pasture, with average
values of 18.9; 16.8 and 16.0 cm plant-1. For fresh pasta, it was observed that the jitirana
was superior to silk-flower and bush-pasture and woods with maximum productivity of
0,9; 0,7 to 0,8 kg m-2 construction, equivalent to 18, 14 and 16 m2 sauces construction, the
quantity of 16.0 t ha-1. The application of spontaneous caatinga species yielded net profit of
R $ 6.070,00, return rate of R$ 2,80 and the profit margin of 64,2% for jitirana. Net profit
of R $ 2.920,00, rate of return of 1.86 and profitability index of 46,3% for the silk-flower
and net profit of R$ 4.270,00, rate of return of 2,26 and profitability index of 55,8%.
Accordingly, the cultivation of coriander fertilized with wild species of the caatinga
constitutes alternatively as green manure.
