Abstract:
A field experiment to study the influence of fertigation of N and K fertilizers on physiology and yield of turmeric (Curcuma longa L.) cv. BSR 2 was carried out during June 2007 to February 2008. The experiment consisted of seven treatments replicated four times in a randomized block design. The physiological parameters viz., crop growth rate, chlorophyll a, chlorophyll b, total chlorophyll, soluble protein and yield parameters viz., number of mother, primary and secondary rhizomes, length and girth of mother, primary and secondary rhizomes, weight of mother, primary and secondary rhizomes, fresh, cured rhizome yield plant-1 and estimated cured rhizome yield hectare-1 were recorded. The study revealed that the fertigation treatments were significantly superior over the control. Among the treatments, N + K @ 100 % level (150 : 108 NK kg ha-1) by fertigation using water soluble fertilizers viz., Urea and Multi ‘K’ registered the highest values for the above parameters.
