Growth and yield response to the application of different bio-stimulants on summer paddy

Abstract

A field experiment was conducted during rabi season of 2017-18 and 2018-19 at “C” block farm B.C.K.V Mohanpur, to study the growth and yield response of rice to the application of different bio-stimulants. The experimental design was “RBD” having ten treatments and three replications.Three types of bio-stimulants (Soligro,Opteine and Biozyme) along with vermiwash are applied in different formulation i.e granular and foliar application and combination of different time of application (Basal, Tillering and Panicle initiation Stage) along with Recommended dose of Fertilizer (RDF). The highest plant height and CGR were observed significantly in 100% RDF+ Soligro Granule at Basal and 30 DAT over control. Highest yield attributes and grain yield found in 100% RDF+ Opteine liquid at 30 DAT and 60 DAT treatment resulting in an increase by 35.03% grain yield, respectively compared to the control. The maximum straw yield was also achieved with the application of 100% RDF+ Soligro Granule at 30 and 60 DAT.
