Short communication Tomato (Solanum lycopersicum L.) response to a liquid formulation of four Glomus strains under field conditions
Main Article Content
Abstract
four Glomus strains as liquid inoculants, at two different doses,
to the experimental areas from the National Institute of
Agricultural Sciences, on a Lixiviated Red Ferralitic soil using
plants of cv. Mara. Soil was prepared by machine and NPK
(9-13-17) fertilizer was applied before transplanting. Some
arbuscular mycorrhizal fungal (AMF) strains were used:
G. hoi-like; G.. intraradices and G.. mosseae, from which liquid
inoculants were obtained. Seedbed stage lasted 30 days and
inoculants were applied seven days after seed germination at
doses of 20 and 40 spores.plant-1, using a randomized complete
design with eight treatments and three repetitions. Some
growth (fresh root weight, dry shoot and root weight, leaf
number, fruit number.plant-1, equatorial and polar fruit diameters
and yield) and fungal variables (percentage of root colonization
and spore number in the soil) were evaluated. Results showed
the liquid inoculant based on G. mosseae strain had a notable
effect on tomato growth and yield indexes. In a similar way,
liquid inoculants based on the other strains at the dose of
40 spores.plant-1 did not have any positive effect.
