Effect of planting geometry and nutrient levels on growth and yield of Isabgol (Plantago ovata) under eastern dry zone of Karnataka

Abstract

The experiment was laid out in a Factorial Randomized Block Design with sixteen treatments and replicated three times. The result indicated that the spacing of 22.5cm recorded significantly maximum plant height (35.09 cm), number of leaves (65.70), number of tillers (13.05), number of spikes (36.50), seed yield (1221 kg /ha) and husk yield (305 kg/ha). Among the different nutrient levels, maximum plant height (34.13 cm), number of leaves (63.95), number of tillers (13.47), number of spikes (35.79), seed yield (904 kg /ha) and husk yield (225 kg/ha) were obtained with the application of 75% RDF (37.5:18.75:22.50 + 7.5 t FYM.) and the interaction of row spacing of 22.5 cm and 75% RDF recorded maximum growth and yield.
