Impact of inorganic, organic and bio- fertilizers on growth and yield of guava (Psidium guajava L.) var. G -27 under Gwalior agro-climatic condition of M.P.

Abstract

Guava is an important fruit crop with regards to its nutritional and commercial value. Production and productivity are the prime concern of the researchers and farmers throughout the world. Looking to the cumulative toxic effects of inorganic fertilizers and chemicals used in maximising the production and productivity, Integrated Nutrient Management is an effective measure. Keeping these facts in view, an experiment was conducted at dryland horticulture farm, Sirsod, College of Agriculture, Gwalior to study the impact of inorganic, organic and bio-fertilizers on growth and yield of Guava (Psidium guajava L.) Var. G-27 under Gwalior agro-climatic condition of Madhya Pradesh during 2018–19 with an objective of studying the effect of inorganic, organic and bio-fertilizers on growthand yield of guava, to find out the best treatment combination of inorganic, organic and bio-fertilizers for increasing the growth and yield of guava and to find out the economic feasibility of treatments. The experiment was laid out in Randomized Block Design with 14 treatments replicated thrice. It was concluded from the experiment that treatment T9 (75% RDF + Vermicompost (5kg) +Bio-fertilizers per plant) gave the best results as far as growth, yield and B:C ratio are concerned.
