The use of biostimulants has been used as a new technology that provides the attenuation of salt stress in plants, as well as a greater increase in plant production. The objective of this research was to evaluate the tolerance and initial development of the Crinson Sweet watermelon submitted to applications of the biostimulant VIUSID-AGRO, grown in saline soil. Five treatments were tested: Soil salinity of 0.6 ...
Intercropping of vegetables in a poorly planned manner may not achieve the expected economic results, as it is an activity that requires a great technical and administrative capacity of the producer. This study aimed to analyze the economic feasibility of intercropping kale with coriander, lettuce, and chives in relation to monocultures. The experiment was conducted in the Center for Agri-food Science and Techn...
A alface é uma das hortaliças folhosas de grande importância comercial e de maior consumo em todo o mundo. Essa espécie apresenta grande resposta à adubação orgânica, sendo uma das fontes dos adubos orgânicas mais utilizadas na agricultura nordestina o esterco de animal, e na região do sertão paraibano, principalmente o ovino. A utilização do espaçamento adequado é determinante para que a planta possa expressar...
A lettuce is one of the most important commercial and consumer stories in the world. This species presents a great response to organic fertilization, being one of the sources of the most pharmacological organic fertilizers in the country's agriculture region, and in the region of the Paraíba hinterland, mainly sheep. The use of adequate spacing and determinant for the production of the product can express its p...
The consortium of vegetables combined with the use of organic compounds as a source of nutrients has been widely used and has proved to be efficient when used as such. However, to avoid compromising the productive process, an economic analysis is necessary. The objective of this work was to evaluate the economic profitability of the lettuce crop in a consortium and monoculture system in function of different ty...
O grau de interferência entre plantas em função da densidade é um dos fatores que afeta a quantidade e qualidade das mesmas, pois quanto maior a densidade de plantas, mais elevada será a concorrência pelos recursos do ambiente. O presente trabalho objetiva avaliar o efeito da competição intraespecífica dos diferentes espaçamentos sobre o crescimento e produção da alface Cristina. O experimento foi conduzido em ...
In the past years, many combinations of plants in intercropping have been demonstrating agronomic viability due to the increase of production per unity of area and greater use of natural resources. However, the knowledge and the proper choice of crops that will be part of the system are necessary to reach achievement, so that there is mutual interaction between them. The study had the purpose of evaluate the pr...

O trabalho objetivou avaliar diferentes substratos na produção de mudas e idade de transplantio para o cultivo da alface. O experimento foi conduzido no Laboratório Didático de Fitotecnia, na Unidade Acadêmica de Ciências Agrárias da Universidade Federal de Campina Grande, UFCG, Campus Pombal, no período de abril a junho de 2009. Os tratamentos foram distribuídos em esquema Fatorial de 2 x 5, sendo o primeiro f...
