Abstract

Applying inorganic fertiliser can boost crop output, but protecting the environment for future generations is burdensome, especially with the ongoing rise in global population. It is possible to achieve sustainable agricultural yield by using fertilisers, both organic and artificial, in a strategic way. Parts of inorganic fertilisers could be replaced with organic fertilisers in order to preserve and boost soil productivity and increase crop yield.

The two year field experiment was conducted at experimental farm at Lovely Professional University, Phagwara, Punjab during the kharif season 2019- 2020 to study the influence of integrated use of organic manures and inorganic fertilizers on physiochemical properties of soil and yield of maize in coarse loamy Typic Haplustept soil with 8 treatments treatments T1- Control, T2 (125:60:30) kg ha-1, T3- RDF +10 ton farmyard manure ha-1, T4- 75% RDF+10 ton farm yard manure ha-1+Vermicompost @ 2 ton ha-1, T5-75% RDF+10 ton farmyard manure ha-1, T6- 50% RDF +10 ton farm yard manure +vermicompost@ 2 ton ha-1 + azotobacter ha-1, T7-50% RDF +15 ton of farmyard manure +azotobacter ha-1, T8-25 % RDF + azotobacter + vermicompost@ 2 ton ha-1 in RBD design with 3 replications.

The soil pH was found highest in T2 (RDF (125:60:30) kg ha-1) (7.41) whereas highest EC was found in T2- RDF (125:60:30) kg ha-1 (0.23 dSm-1). The highest bulk density found under T1 (Control) (1.83 g cm-3) and porosity was highest in T6 (50% RDF +10 ton farm yard manure + vermicompost@ 2 ton ha-1 + azotobacter ha-1) (36.66%). In T6 (50% RDF +10 ton farm yard manure + vermicompost@ 2 ton ha-1 + azotobacter ha-1), the highest amount of nitrogen (312.3 kg ha-1), phosphorus (25.6 kg ha-1), potassium (285.33 kg ha-1) and organic carbon (5.6g kg-1) was found. In terms of yield parameters, the grain yield (4223 kg ha-1), straw yield (5266 kg ha-1), harvest index (41.53%) and 1000-seed weight (286.66 gm) was found highest in T6 (50% RDF +10 ton farm yard manure + vermicompost @ 2 ton ha-1 + azotobacter ha-1). There are significant difference in all the treatements with respect to the physico-chemical properties of soil and yield paramters of maize.
