Abstract

A field experiment was conducted during rabi season 2019- 20 at Agricultural Research Station, Navgaon (Alwar), S.K.N Agriculture University, Jobner, Jaipur (Rajasthan) India, to study the effect of water soluble fertilizer on yield of mustard. The experiment was laid out in a randomized block design with eleven treatments and replicated thrice. The crop was sown as per the package of practices recommended for zone IIIB of Rajasthan. The treatments were application of 50 % RDF (N:P2O5:K2O 40:20:20 kg ha-1), 75 % RDF (N:P2O5:K2O 60:30:30 kg ha-1), 100 % RDF (N:P2O5:K2O 80:40:40 kg ha-1 ), 50 % RDF + foliar spray of 19:19:19 @ 2% , 75 % RDF + foliar spray of 19:19:19 @ 2%, 50 % RDF + foliar spray of DAP @ 2%, 75 % RDF + foliar spray of DAP @ 2%, 50% RDF + foliar spray of urea @ 2%, 75% RDF + foliar spray of urea @ 2%, including foliar water spray and Control. Among the treatments, application of water soluble fertilizer i.e. 75 % RDF + foliar spray of 19:19:19 @ 2% was recorded significantly higher plant height at 30, 60, 90, 120 DAS and at harvest stage, 23.4 cm, 118.2 cm, 156.6 cm, 197.5 cm, 198.9 cm respectively), siliqua per plant (159), seed per siliqua (14), test weight (4.98 gm), seed yield (3666 kg ha-1), stover yield (9780 kg ha-1), with higher harvest index (27.25%) and gross returns (Rs.162211 ha-1) and net returns (Rs.127804 ha-1). However, benefit cost ratio established its economic superiority over other treatments. However, it remained at par with 50 % RDF (N:P2O5:K2O 40:20:20 kg ha-1), 75 % RDF (N:P2O5:K2O 60:30:30 kg ha-1), 100 % RDF (N:P2O5:K2O 80:40:40 kg ha-1), 50 % RDF + foliar spray of 19:19:19 @ 2% , 50 % RDF + foliar spray of DAP @ 2%, 75 % RDF + foliar spray of DAP @ 2%, 50% RDF + foliar spray of urea @ 2%, 75% RDF + foliar spray of urea @ 2%. However, foliar water spray and control were recorded significantly lowest plant height, siliqua per plant, seed per siliqua, test weight, seed yield, stover yield with higher harvest index (%) and gross returns, net returns and BC ratio.
