Response of dry seeding of kharif paddy (Oryza sativa L.) varieties to different fertilizer levels on economics

Abstract

The agronomic investigation entitled, “Response of dry seeding of Kharif paddy (Oryza sativa L.) varieties to different fertilizer Levels” was undertaken at Post Graduate Research Farm, Agronomy Section of Rajarshee Chhatrapati Shahu Maharaj College of Agriculture, Kolhapur (M.S.), India during Kharif, 2019. The experiment was laid out in a split plot design with four replications and nine treatment combinations comprising of three varieties V1- Indrayani, V2- Phule Radha and V3- Bhogawati as main plot treatments and three fertilizer levels F1- 75% RDF, F2- 100% RDF and F3- 125% RDF as sub plot treatments on sandy clay loam soil. The gross monetary returns (Rs. 155818 ha-1), the net monetary returns (Rs. 84931 ha-1) and benefit: cost ratio (2.20) was significantly more with the variety Indrayani and which was at par with Bhogawati and significantly superior over Phule Radha. The application of 125% RDF ha-1 had significantly maximum gross monetary returns (Rs. 154360 ha-1), net monetary returns (Rs. 83397 ha-1) and B: C ratio (2.18) which was at par with application of 100% RDF ha-1 and significantly superior over 75% RDF ha-1. The effect of interactions between paddy varieties and fertilizer levels were significantly influenced the economics of paddy. The interaction effect of the variety Indrayani fertilized with 125% RDF recorded maximum gross monetary returns (Rs. 168924 ha-1), net monetary returns (Rs. 97524 ha-1) and also B: C ratio (2.37) over rest of all the remaining interaction combinations.
