Lettuce crop management to control phytonematodes and agroecological transition

Lactuca sativa; Meloidogyne spp; liming; organic fertilizer.

The project aims to develop and improve agricultural practices and phytonematode management methods in lettuce production on a property undergoing agroecological transition in the municipality of Rosário da Limeira-MG, aiming to increase productivity, reduce environmental impact and balance the agroecosystem.

Specific objectives

a) Compare different phytonematode management methods and their impact on soil production, quality and health.

b) Investigate and evaluate the influence of organic matter management and soil acidity correction on the control of phytonematodes for lettuce crops, using chicken litter, biochar and green manure with sunn hemp.

 c) Evaluate the use of composting chicken litter and composting chicken litter with Biochar to control phytonematodes in lettuce and maintain organic matter in the soil, in addition to being a source of nutrition.

 d) Identify and establish a relationship between biotic and abiotic factors that favor the occurrence of and damage caused by phytonematodes in the agroecosystem, with an emphasis on organic agricultural systems.

e) Develop a booklet containing management practices and techniques for controlling phytonematodes, specifically aimed at organic and agroecological farmers, aiming to provide practical and applicable information.

f) Test tolerance or resistance of the BRS Leila and BRS Mediterrânea varieties.
