Evaluation of crotonylidene diurea in turmeric

Abstract

A Field experiment was conducted to evaluate Crotonylidene Di-urea (CDU) fertilizer on Turmeric crop at ICAR-Krishi Vigyan Kendra, Sirsi of University of Agricultural Sciences, Dharwad, Karnataka during 2015-16. The testing product Crotolydene Diurea was evaluated for its effect on Turmeric and compared with urea fertilizer and in different proportionate. The results revealed that significantly higher plant height, number of tillers and number of leaves, fresh rhizome yield, number rhizome fingers per plant, rhizome length, rhizome girth, rhizome yield per plant were observed in the treatment receiving 100% N through CDU (T1) and which was onpar with 75% N through CDU + 25% N through Urea(T3). Significantly higher N,P and K uptake by crop was recorded with the same treatment. The lowest values of all the parameters were recorded with treatment 100% N through Urea (T2) recorded significantly lower.
