Endomycorrhizal Inoculation Effect On Beans (Phaseolus vulgaris L.), OAT (Avena sativa L.), And Wheat (Triticum aestivum L.) Growth Cultivated In Two Soil Types Under Greenhouse Conditions
The objective of this research was to evaluate the effect of inoculation with Glomus intraradices on oat, beans, and wheat. The study was done under greenhouse conditions at the Montecillo Campus of the Postgraduate College, Mexico. Two soil types from San Luis Potosà State were used, one was red (Xerosol), and the other one was grey (Litosol). With and without Glomus intraradices inoculation. Three bean cultivars: Pinto Saltillo, Bayo comercial and Flor de Mayo; Chihuahua (oat variety); and Tlaxcala wheat genotype were planted. The experimental design was factorial complete randomized block and three replications. The result showed that bean yield (average 3.7 g plant-1), pod number and dry weight, leaf area, plant height, stem diameter, and aerial part dry weight were positively affected by the inoculation with Glomus intraradices, but not by soil type. A similar trend was observed in root length, volume and dry weight, and in the nodule number. In relation with the species studied, Phaseolus vulgaris varieties had higher values than wheat and oats in growth and yield variables evaluated. It is concluded that endomycorrhiza inoculation (Glomus intraradices) gave better growth and yield, especially in beans. The soil types studied did not affect significantly plant responses in this study
Fungicide Effect on Glomus Intrarradices in Different Genotypes of Beans (Phaseolus Vulgaris L.), OAT (Avena Sativa L.), and Wheat (Triticum Aaestivum L.) Growth Cultivated in Two Soil Types under Greenhouse Conditions
The objective of this research was to evaluate the effect of fungicides on the association with Glomus intraradices and soil contamination on three genotypes of beans (Phaseolus vulgaris L.), one of oat (Avena sativa L.), and another one of wheat (Triticum aestivum L.). The study was done under greenhouse conditions at the Montecillo Campus of the Postgraduate College, Mexico. Two soils were used, one irrigated with sewage water and the other one with clean water from a well. Half of the plants were inoculated with Glomus intraradices. Metacaptan was used as a fungicide applied to half of the seeds. The pH of the soil was alkaline. Electric conductivity, and organic matter, nitric and ammoniac nitrogen, phosphorous, copper and nickel quantities were higher on the soils irrigated with sewage water. The soil contamination did not affect significantly plant responses in this study. It is concluded that endomycorrhiza inoculation (Glomus intraradices) gave better growth and yield, especially in beans. The application of fungicides improved plant growth
