Description
Summary:Arbuscular mycorrhizal fungi (AMF) allow plants to make better use of water and minerals. This alliance concerns the majority of crops and might greatly limit their dependence on fertilizers. In this work, AMF contribution and moderate fertilization were assessed for their impact on root colonization, growth, yield, number of fruits and soluble dry matter of tomato (Solanum lycopersicum L. var. Fahla F1) in a Mediterranean agroecosystem (El-Tarf, Algeria). The soil had a low available phosphorus content and a low mycorrhizal potential. Tomato seedlings were uninoculated (M−) or inoculated (M+) with a commercial AMF inoculum. Three NPK (10.42.10) fertilizer rates corresponding to 0, 2000 and 4000 mg plant−1 were applied. Mycorrhizal inoculation significantly increased root colonization levels (+48%), height (+8.78%), shoot dry biomass (+21.5%), root dry biomass (+34.45%), total yield (+8.07%) and number of fruits (+19.05%). NPK decreased root colonization levels; however, it enhanced significantly tomato growth with the highest shoot dry biomass obtained with 2000 mg plant -1. Total yield and number of fruits increased with increasing NPK rate; the highest yield occurred with 4000 mg plant−1. Soluble dry matter was not affected by AMF or NPK. Tomato inoculation combined to a reduced fertilization can provide appreciable gains in terms of growth and yield in a low P soil with a low mycorrhizal potential, which enhances agricultural sustainability due to a decreased impact of fertilizers.
