Influence of Bio-fertilizer on guava (Psidium guajava L.) cultivation in gangetic alluvial plain of West Bengal, India
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
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) with maximum fruit length, diameter, fruit weight and pulp weight, this was followed by the treatment with Azospirillum brasilense + Bacillus megatherium. The same treatment combination exerted maximum peak in quality parameters like TSS (10.30o Brix), total sugar (7.85%) and ascorbic acid (153.44 mg100-1 g of pulp) by increasing the leaf mineral content and soil microbial population substantially. So, for getting higher yield and quality fruit of guava, Azospirillum brasilense + AMF may be a good option for the guava-growers in gangetic alluvial plain of West Bengal.
