ABSTRACT
 
The experiment was conducted at horticultural farm of IAAS, Rampur from November, 2012 to March, 2013 to evaluate the efficacy of the different sources of nitrogen (inorganic-urea and organic-FYM) on the performance of late varieties of cauliflower. The experiment was laid out in two factor factorial randomized complete block design (RCBD) with three replications. The experiment comprised of 12 different treatment combinations: three different sources of nitrogen (100% N through urea, 50% N through urea + 50% N through FYM, and 100% N through FYM) and four varieties (Snow Mystique, Snow Crown, Snow Dome and Madhuri) of Cauliflower. Various growth attributing characters: plant height, number of leaves per plant and curd height were observed better in performance through 50% N-Urea + 50%N-FYM with Madhuri variety compared to other treatments. Snow Dome took the longest period to 50% curd initiation (74.22 days) and 100% curd imitation (79.44 days). Similarly, Snow Crown took the shortest period to 50% curd initiation (49.56days) and 100% curd imitation (55.56days). The maximum  curd height (7.52cm), curd diameter (16.66cm), maximum plant height at harvest (58.28cm), highest number of leaves per plant (13.93) and the highest economic yield (24.82tha) were recorded from 50%N-Urea+50%N-FYM. The highest plant height at harvest( 59.52cm), highest numbers of leaves per plant (15.06),maximum curd height (7.52 cm), curd diameter (17.20cm) and highest economic yield (27.78 tha) was recorded from Madhuri compared to other varieties. The higher yield of Madhuri was because of better vegetative growth which resulted in higher length, diameter and weight of curd. Fifty percent substitution of nitrogen requirement through FYM produced better performance in terms of morphological traits and yield parameters as compared to other combination of FYM and urea. It can be suggested that the open pollinated variety Madhuri can be grown with the combination of 50%N from FYM and 50%N from Urea in the late season under Chitwan condition.
