Impact of vermicompost, nitrogen and phosphorus on yield, quality and uptake of coriander (Coriandrum sativum L.) under arid condition

Abstract

The use of vermicompost, Nitrogen (N) and phosphorus (P) as organic and inorganic sources under arid condition was tested in this study. Accordingly, a field experiment was carried out and Coriander (Coriandrum sativum L.) was grown in the research farm of agronomy, College of Agriculture, SKRAU, Bikaner. The experiment was conducted based on split plot design using three replications. Twenty seven treatment combinations i.e. three levels of vermicompost (control, 2.5 and 5.0 t ha-1), three levels of nitrogen (control, 40 and 80 kg ha-1) as main plot treatment and three levels of phosphorus (control, 20 and 40 kg P2O5 ha-1) as sub plot treatment was laid out. From the results, among all the treatment combined application of vermicompost @ 2.5 t ha-1 with N level @ 40 kg ha-1 and P level 20 kg ha-1 significantly increased all the yield, quality and uptake parameters viz., seed, stover and biological yield, oil and protein content, total N, P and K uptake by coriander over the other treatments. However, fiber content of coriander not increased significantly with application of these treatments. Therefore, it appears more logical to recommend a more realistic dose of 2.5 t vermicompost ha-1, 40 kg N ha-1 and 20 kg P ha-1 for coriander crop grown on loamy sand soil under irrigated conditions of north western Rajasthan to make the fertilizer use more gainful with considerable response
