Résumé:
In recent years many plant combinations in intercropping have been studied and
have demonstrated agronomic viability due to increased production per unit área and
better use of natural resources. Alternative inputs, such as animal waste, crop
residues, and green manures have been used mainly to increase the amount of
organic matter in the soil, increasing the nutrient content, thereby providing an
increase in crop yield and reduce production costs and negative effects on the
environment. Thus, the objective is to evaluate the growth and productivity the culture
of lettuce and coriander in intercropping system and in monoculture under different
types of fertilizer in two crops. The experimenta were conducted on the premises of
the Centro de Ciências e Tecnologia Agroalimentar (CCTA) of the Universidade
Federal de Campina Grande, municipality of Pombal-PB. The treatments consisted of
types of fertilizers and farming systems in a factorial 6 x 2, with the first six factor
fertilizations: 1= Cow Dung (Fertilization with Animal Waste)l 2: Green manure
(Guandu beans)l 3: Green manure and cow dungl 4= Mineral Fertilizationl 5=
Organomineral fertilization and 6= Merger of spontaneous vegetation and the second
factor of two farming systems: 1= intercropping and 2= monocropping. The
experiments were conducted in randomized block design with four rep.lications. In
both crops, Cristina and Verdão seed were used, respectively for lettuce and
coriander. The lettuce (main culture) was transplanted at a spacing of 0.30 m
between rows and 0.25 m between plants in both culture systems. In intercroping,
coriander was sown on lettuce lhes. In both consortia as in monocultures coriander
spacing was 0.25 m between rows. There was no contrai of the spacing between
plants to coriander, thus standardizing up the amount of 3 g of seed per meter of
furrow. The characteristics evaluated were plant height, head diameter. fresh weight
and shoot dry, productivity and index of the efficient use of land (UET). The data was
subjected to analysis of variance, the averages were compared by Tukey test at 5%
probability. It was observed that, for the first crop, the highest values of growth
characteristics and lettuce productivity were monocropping when fertilized with caule
manure alone or in combination with green manure and with mineral fertilizerl the
second crop, there was this same behavior, but with high values. The combination of
animal manure with green manure provided higher yields Coriander in both crops.
Coriander had its best performance in the intercropping or similar to monocropping in
both crops, regardless of the fertilizer used. The mineral fertilization only promoted
good yields for the first crop of lettuce and cilantro. The UET has shown that all
consortia were viable in the efficient use of band.
