Influence of Bio-fertilizer on guava (Psidium guajava L.) cultivation in gangetic alluvial plain of West Bengal, India

Abstract

A field experiment was conducted at the farmer's field, Gayeshpur, Nadia, West Bengal during 2013-15 to study the effect of different bio-fertilizers on yield, fruit quality and leaf mineral composition of guava cv. L-49. The experiment was implemented using a randomized complete-block design with three replicates. Ten treatments of different bio-fertilizers alone and in combinations along with one chemical and absolute control i.e. no fertilization treatment were applied on 6 years old guava plant. Among different treatments of bio fertilizers, Azospirillum brasilense + AMF (Arbuscular mycorhizal fungi) showed highest (56.30%) fruit retention and maximum fruit yield (41.3 kg plant -1

Hongos micorrízicos nativos como promotores de crecimiento en plantas de guayaba (Psidium guajava L.)

“…On the other hand, the greatest guava plant growth obtained from seeds and inoculated with different species and the arbuscular mycorrhizal fungus combination has been reported previously (Estrada-Luna et al, 2000;Schiavo and Martins, 2002;da Silva-Campos et al, 2013;Mohandas et al, 2013;Das et al, 2017). In general, this study found an increase in guava plants propagated by seeds when a mycorrhizal consortium was applied.…”

“…Por otro lado, el mayor crecimiento de plantas de guayaba obtenidas de semilla e inoculadas con diferentes especies y combinaciones de HMA ya ha sido reportada previamente (Estrada-Luna et al, 2000;Schiavo y Martins, 2002;da Silva-Campos et al, 2013;Mohandas et al, 2013;Das et al, 2017). En general, en este trabajo se encontró un aumento en el crecimiento de las plantas de guayaba propagadas por semilla cuando se les aplicó algún consorcio micorrízico.…”

“…Los incrementos alcanzados por estas plantas respecto a plantas sin HMA, en promedio fueron de 9, 4.4, 332 y de más de 145 veces, para la altura de planta, diámetro de tallo, materia seca total y el área foliar respectivamente. Incrementos similares en variables de crecimiento han sido reportados en guayaba por efecto de la inoculación con HMA (Estrada-Luna et al, 2000;da Silva-Campos et al, 2013;Das et al, 2017). Por otro lado, a pesar de Another possible cause of greater growth promotion in mycorrhizal consortia could have been an effect of the propagation method (tramp pot) when rhizosphere soil propagates; besides the AMF, this soil had microorganism diversity, mainly bacteria associated to free-life spores that have the capacity of promoting plant growth.…”

“…Similar growth results were reported by Schiavo and Martins (2002) with Glomus clarum, Panneerselvam et al (2012); Glomus mosseae, da Silva-Campo et al (2013); Acaulospora longula, Gigaspora albida and Glomus etunicatum. On the other hand, Das et al (2017) reported an increase in guava plant production mycorrhized with Glomus mosseae.…”

“…Resultados similares en el crecimiento reportan Schiavo y Martins (2002) usando Glomus clarum, Panneerselvam et al (2012) usando Glomus mosseae, da Silva-Campo et al (2013) con Acaulospora longula, Gigaspora albida y Glomus etunicatum. Por su parte, Das et al (2017), reportan un incremento en la producción en plantas de guayaba micorrizadas con Glomus mosseae.…”
