Cultivation of Pea (Pisum Sativum) Affected by Biostimulant Amendments and Microbial and Organic Used As İnoculants.

Abstract

: The state of Mexico, with its 22,000km² being one of the 32 states in the country, is one of the main producers of pea (Pisum sativum) in Mexico, whose production is carried out under conventional agriculture which uses agrochemicals that lead to erosion and loss of soil fertility. Hence, an alternative to soil improvement is to use biostimulant-type amendments and microbial and organic inoculants. The objective was to study three types of amendments in response to the pea plant (Pisum sativum) in agricultural soil under 12 treatments: 4 non-inoculated settings and 8 inoculated ones with Azospirillum and arbuscular mycorrhizal fungi, vermicompost, algae paste, and inorganic fertilizers. The study was carried out in the field. The production of CO2, the carbon of the microbial biomass, the organic matter, qCO2 (the metabolic quotient) was determined. The variables of height, fresh and dry weight, biomass, and SPAD units were measured in the plant. The results revealed an increase in fresh and dry weight as well as height due to the addition of mycorrhizae, Azospirillum, vermicompost, and algae paste, which suggested a favorable and sustainable option in the mitigation of environmental effects from mineral fertilizers by using biofertilizers.
