Abstract
The present study entitled, “Integrated nutrient management in barley” was conducted during
the Rabi season of 2017-2018 at the Agronomy Research Farm of Chaudhary Charan Singh Haryana
Agricultural University, Hisar with the objective to study the effect of different nutrient management
practices on growth, yield, quality and economics of barley. The experiment was laid out in Randomized
Block Design replicated thrice with ten different treatments viz. T1(Control) , T2 (Biomix) , T3
(Vermicompost @ 5 t ha-1), T4 ( Biomix + Vermicompost @ 5 t ha-1), T5 (50 % RDN + Vermicompost @
5 t ha-1), T6 (75 % RDN + Vermicompost @ 5 t ha-1), T7 (50% RDN + Biomix + Vermicompost @ 5 t
ha-1), T8 (75 % RDN + Biomix+ Vermicompost @ 5 t ha-1), T9 (RDN) and T10 (RDN + Biomix +
Vermicompost @ 5 t ha-1). Among nutrient management practices treatments T10 recorded significantly
higher growth parameters viz. [plant height (cm), LAI, number of tillers / m.r.l. and dry matter
accumulation/plant (g/plant)], yield attributing characters [Number of grains per spike and spike length
(cm) ] , grain, straw and biological yield (kg ha-1), protein content, N, P and K content in grain and straw
(except K content in straw), gross returns, net returns and benefit: cost ratio of barley. Performance in
terms of growth, yield, nutrient studies, quality and economics of barley in treatment T8 (75 % RDN +
Biomix+ Vermicompost @ 5t ha-1) was at par with treatment T9 (RDN) and T10 (RDN + Biomix +
Vermicompost @ 5t ha-1). Treatment T10 took highest number of days to flag leaf emergence, booting,
anthesis and maturity as compared to other treatments. Treatment T1 being at par with treatment T2
recorded significantly higher value of malt content of barley than treatment T3 to T10. But various
combinations of nitrogen fertilizer, biomix and vermicompost failed to produce any significant variation
in days taken to emergence and tillering, plant population at 20 DAS, test weight, harvest and attraction
index, quality parameters like hectoliter weight and boldness as well as thinness of barley grain, K content
(%) in straw and available N, P and K status of soil after the harvest of barley.
