Response of soluble synthetic fertilizers with varying concentration of liquid manures on growth and yield of mustard at Dehradun district of Uttarakhand

Abstract

This study was performed at Agriculture research farm of Shri Guru Ram Rai University, Dehradun, (U.K), India. In order to investigate the effect of soluble nutrients with varying concentration of liquid manure on growth parameters, various yields and yield attributes of mustard crop, field experiment was carried out during summer season (2019-20) at Research Block of S.G.R.R. University, Dehradun Uttarakhand. The layout of experimental field was laid randomized block design (RBD) with 7 treatments and 3 replications. Consisting of T1 (Control), T2 RDF (NPK 12:32:16), T3 (Vermiwash) @5%, T4 (cow urine) @5%, T5 (vermiwash @5% +cow urine @ 5%), T6 (N: P: K (19:19:19) Soluble @ 2%+cow urine @ 5%)), T7 (N: P: K (19:19:19) Soluble @ 2% +vermiwash @5%). All treatments were applied two times at 20 days interval. The results indicated that among all the treatments, T7 (N: P: K (19:19:19) Soluble @ 3% +vermiwash @5%), overall was found best for farmer point of view with respect to plant height (113.3 cm), number of seeds/siliqua (18.3), test weight (1000 –seed weight) (4.36gm), seed yield (1515.9 kg/ ha), and stover yield (1851.81 kg/ ha) at harvest and net return (51407.5 rs/ha), gross return (70787.5), B:C ratio (2.65). Based on present investigation, it can be concluded that the combination of both soluble fertilizer with liquid manure are applied that improved yield and yield attributes of mustard crop under present agro-climatic conditions.
