Yield and Quality of Isabgol (Plantago ovata Forsk) as Influenced by Planting Geometry and Nutrient Levels under Eastern Dry Zone of Karnataka

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 number of spikes (36.50), seed yield (1221 kg /ha), husk yield (305 kg/ha), swelling factor (13.70 cc /g) and protein content (11.91%) in the seeds. Among the different nutrient levels, maximum number of spikes (35.79), seed yield (904 kg /ha), husk yield (225 kg/ha), swelling factor (13.93 cc /g) and protein content (12.24 %) of seeds 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 yiled and quality parameters found non significant.
