Effect of Sugarcane Trash Biochar on Growth and Yield of Sugarcane Seed Crop

Abstract

                                A field experiment was conducted at Sugarcane Research Station, Cuddalore with the objective to ascertain the effect of sugarcane trash biochar on growth and yield of sugarcane seed crop during special season 2017- 2018. The variety used was CoC 25 and the treatment consists of Recommended NPK alone (300:100:200 kg ha-1), Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1, 50 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1+ Bio-fertilizer @ 10 kg ha-1, 75 per cent Recom. NPK+ sugarcane trash Bio-char @ 2 t ha-1 + Bio fertilizer @ 10 kg ha-1, 100 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio-fertilizer @ 10 kg ha-1, 125 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio fertilizer @ 10 kg ha-1, 150 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio fertilizer @ 10 kg ha-1. Integrated Nutrient Management practice of 150 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio-fertilizer @ 10 kg ha-1 recorded higher growth and yield attributes viz., plant height, tiller population, root length, dry matter production, single cane weight and seed cane yield. This was followed by 125 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio fertilizer @ 10 kg ha-1. But, higher benefit cost ratio was obtained with the application of 100 per cent Recom. NPK + sugarcane trash Bio-char @ 2 t ha-1 + Bio-fertilizer @ 10 kg ha-1

Key words : Sugarcane, Biochar, Seed cane yield

(7.15 mg kg-1) recorded in the treatment T5 which received 100% RDF + Vermicompost @ 5 t ha-1. The post harvest available K (77.48 mg kg-1) was registered with application of 100% RDF + Lignite Flyash @ 10 t ha-1 (T9 ).

Key words : : Brinjal, Municipal solid waste compost, Vermicompost, Rice husk ash, Lignite flyash. .
