Effect of integrated nitrogen management on yield and quality characters of dill seed (Anethum graveolens L.) under north Gujarat agro-climatic condition

Abstract

An experiment was conducted on loamy sand soil of Instructional Farm, Department of Agronomy, Chimanbhai Patel College of Agriculture, S.D. Agricultural University, Sardarkrushinagar (Gujarat) during the Rabi season of years 2011-12 and 2013-14 on to study “Integrated Nitrogen Management in Dill Seed (Anethum graveolens L.) under North Gujarat Agro-Climatic Condition” in Randomized Block Design (RBD) with three replications and Fourteen treatment combinations comprising urea, FYM, vermicompost and bio-fertilizer application and Gujarat dill seed 3 was used as test crop. The pooled results of yield and quality characters like as significantly maximum seed yield, stover yield, biological yield, essential oil content and essential oil yield were recorded in application of 75% RDN through urea + 25% RDN through vermicompost (T6) which was followed by 50% RDN through urea + 50% RDN through vermicompost (T8) and 75% RDN through urea + 25% RDN through FYM (T5). Application of 100% RDN through FYM recorded significantly lower value of yield and quality characters as compare to all other treatments.
