Correlations Between Pratylenchus and Meloidogyne Populations, Soil Chemical Properties, Soil Texture, and Nutritional Status of Soybean Crops in Paraguay

Nematodes cause great damage to soybean crops in Paraguay. Studies have investigated correlations between phytonematodes and soil chemical physical properties, but little is known about with the nutritional status of crops. This study aimed assess Pratylenchus, Meloidogyne, texture, soybean. The experiment was carried out Paraguay areas commercial cultivation infested nematodes, totaling 83 collection sites. Analyses nematodes root samples, characterization acidity, fertility, leaves were performed, 36 variables. Data subjected principal component analysis. Soil Al3+ favored development Pratylenchus populations. Organic carbon negatively influenced Meloidogyne. K+ Mg2+ affected respectively. Meloidogyne correlated clay contents. In sandy soils, there a negative correlation sand content. led an increase foliar Ca decrease P. fertility management can be used as part integrated It worth mentioning that, field studies, complexity biotic abiotic factors crop system may contribute diverging results, making it difficult establish single response pattern, especially when some affect others.
