Influence of consortium of endophytic nitrogen fixing bacteria with levels of nitrogen on yield attributing characters of Pre-Seasonal sugarcane (Second Ratoon)

Abstract

A field experiment was conducted during the year 2015-16 at the Post Graduate Institute Farm, Mahatma Phule Krishi Vidyapeeth, and Rahuri, to study the “Effect of consortium of endophytic nitrogen fixing bacteria on yield, quality and nutrient uptake of pre-seasonal sugarcane (second ratoon). The experiment was laid out in randomised block design with four replications and six treatments. There were four levels of nitrogen 0, 25, 50 and 100% and 100% P2O5, 100% K2O along with and without foliar spray of consortium of endophytic nitrogen fixing bacteria. The result of the experiment revealed that Total cane height, Millable cane height, Girth of internodes, Length of internodes and No. of millable canes of pre-seasonal sugarcane (second ratoon) were increased with foliar spray of consortium of endophytic bacteria along with 25% N of RDF. Among all the treatments, 100% N (RDF) recorded significantly highest yield attributing characters.
