Combining ability study for yied and its component in Indian mustard (Brassica juncea (L.) Czern & Coss)

Abstract

Cogen ash, a by-product of sugar mills obtained during co-generation process to produce heat and electrical energy by burning bagasse and/or coal was used to study its effect on yield, nutrient content and uptake of paddy. The experiment was conducted in research block of Sri Chamundeshwari Sugars Ltd., K.M. Doddi, Mandya during kharif 2014 with 13 treatments replicated thrice using RCBD. Straw and grain yield was increased with increasing levels of cogen ash and further increased when applied along with recommended doses of FYM and chemical fertilizers. Data indicated that macro and micro nutrient content in paddy grain and straw was significantly higher in treatment T9 which received RDF + RD FYM+ 15.0 t ha-1 cogen ash compared to all the other treatments, and in majority the same treatment showed significantly higher uptake of nutrients.
