Effect of water soluble fertilizers on growth parameters and economics of coriander (Coriandrum sativum L.)

Abstract

An experiment entitled “Effect of water soluble fertilizers on growth parameters and economics of coriander (Coriandrum sativum L.)” was carried out under medium black clayey soil and slightly alkaline soil in reaction with pH 7.9 and EC 0.49 dSm-1 during rabi season of 2016-17 at the Instructional Farm, Department of Agronomy, College of Agriculture, Junagadh Agricultural University, Junagadh. The experiment consisting of 10 treatment combinations, comprising (T1) control, (T2) RDF + water spray, (T3) RDF + WSF (19:19:19), (T4) RDF + WSF (13:40:13), (T5) RDF + WSF (12:61:00), (T6) RDF + WSF (00:52:34), (T7) RDF + WSF (28:28:00), (T8) RDF + WSF (00:00:50:17.5 S), (T9) RDF + Urea and (T10) RDF + KNO3. Foliar spray of water soluble fertilizers (WSF), urea and KNO3 was done @ 2 per cent at 30, 45 and 60 days after sowing. Recommended dose of fertilizers was applied at the time of sowing. These treatments were evaluated under randomized block design with 3 replications. The results of experiment indicated that growth parameters viz., plant height and branches per plant at harvest, dry matter accumulation at 60, 90 DAS and at harvest increased significantly with the application of RDF 20:10 kg NP ha-1 + foliar application of WSF (19:19:19) @ 2 per cent at 30, 45 and 60 days after sowing and also gave significantly higher gross return of
