SUMMARY
A field experiment was conducted at Agronomy Research Area, CCSHAU, Hisar during kharif 2016 with the objective to study the effect of manure and nitrogen level on nutrient uptake, soil fertility and economics of pearl millet hybrid HHB-223. The experiment was conducted in split plot design with three replications. In the main plot, there were manurial treatments viz., control, biomix, vermicompost @2.5 t/ha and vermicompost @ 2.5 t/ha+biomix and nitrogen levels viz., 70, 80, 90 and 100 per cent RDN were kept under sub-plot. Higher N, P, K content and uptake were with biomix+vermicompost @2.5 t/ha and 100 per cent RDN. Availability of nutrient (N, P and K) after harvest in soil increased with increasing level of nitrogen and was highest in biomix+vermicompost @ 2.5 t/ha treatment among manurial treatment. In manurial treatment higher gross return (Rs. 50252) and net returns (Rs. 17532) were recorded with biomix+vermicompost @ 2.5 t/ha. Gross return, net returns and B : C ratio of pearl millet increased with increasing level of nitrogen and highest values were recorded with 100 per cent RDN and were Rs. 48217, Rs. 21036 and 1.77, respectively, but almost comparable with 90 per cent RDN. Hence, to enhance yield and monetary returns, pearl millet seed should be treated with biomix and fertilized with 90 per cent RDN along with vermicompost application @ 2.5 t/ha.
Key words: Manure, nutrient uptake, soil fertility, economics, pearl millet
