Evaluation of Different Sources of Nitrogen and Bio-Fertilizers on Growth and Yield of Isabgol (Plantago ovate)

A field experiment was conducted during the year 2016–17 at the Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Horticulture, Mandsaur to study the effect of different sources of nitrogen and bio-fertilizers on growth and yield of Isabgol. The experiment was laid out inrandomized block design (RBD) with three replicationsand ten treatments comprised of graded levels of recommended dose of nitrogen (RDN), vermi-compost, FYM and bio-fertilizers (Azotobactor + PSB). The resultsindicated that the growth and yield of isabgol crop can be increased by treatment T2(50% RDN through urea and 50% RDN through vermi-compost (40 kg N/ha) + bio-fertilizers as Azotobactor + PSB 3 kg/ha each).
